Given that ∠ABC ≅ ∠DBE, which statement must be true?

∠ABC ≅ ∠ABD
∠ABD ≅ ∠CBE
∠CBD ≅ ∠DBE
∠CBD ≅ ∠ABC

Answers

Answer:

The Correct Answer Is: ∠ABD ≅ ∠CBE

Step-by-step explanation:

I just took the test

∠ABD≅∠CBE is the true statement of congruent angles as per the given condition ∠ABC ≅∠DBE.

What are congruent angles?

" Congruent angles are pair of such angles which are equal in their measurements."

According to the question,

Given,

∠ABC ≅∠DBE                                    ________(1)

As shown in the diagram drawn as per the given conditions we have,

'D' is the interior point of angle ABC.

Therefore,

∠ABC = ∠ABD + ∠CBD                         ______(2)

'C' is the interior point of ∠DBE.

Therefore,

∠DBE = ∠CBD + ∠CBE                              ______(3)

Substitute  (2) and (3) in (1) to represent congruent angles we get,

∠ABD + ∠CBD  ≅ ∠CBD + ∠CBE      

∠ABD   ≅  ∠CBE                            (∠CBD is common in both)

Hence, ∠ABD≅∠CBE is the true statement of congruent angles as per the given condition ∠ABC ≅∠DBE.

Weights and heights of turkeys tend to be correlated. For a population of turkeys at a farm, this correlation is found to be 0.64. The average weight is 17 pounds, SD is 5 pounds. The average height is 28 inches and the SD is 8 inches. Weight and height both roughly follow the normal curve. For each part below, answer the question or if not possible, indicate why not. A turkey at the farm which weighs more than 90% of all the turkeys is predicted to be taller than % of them. The average height for turkeys at the 90th percentile for weight is Of the turkeys at the 90th percentile for weight, roughly what percent would you estimate to be taller than 28 inches?

Answers

Answer:

a turkey at the farm which weighs more than 90% of all the turkeys is predicted to be taller than 79.37 % of them.

The  average height for turkeys at the 90th percentile for weight is 34.554

Of the turkeys at the 90th percentile for weight, roughly the percentage that  would  be taller than 28 inches 79.37%

Step-by-step explanation:

The data given for the study can be listed as follows

For a population of turkeys at a farm, the correlation found between the weights and heights of turkeys is r = 0.64

[tex]\overline x[/tex] = 17  (i . e the average weight in pounds)

[tex]S_x[/tex] = 5 ( i . e the standard deviation of the weight in pounds)

[tex]\overline y[/tex] = 28 (i . e the average height in inches)

[tex]S_y[/tex] = 8 ( i . e the standard deviation of the height in inches)

The slope of the regression line can be expressed as :

[tex]\beta_1 = r \times ( \dfrac{S_y}{S_x})[/tex]

[tex]\beta_1 = 0.64 \times ( \dfrac{8}{5})[/tex]

[tex]\beta_1 = 0.64 \times 1.6[/tex]

[tex]\beta_1 = 1.024[/tex]

Similarly the intercept of the regression line can be estimated by using the formula:

[tex]\beta_o = \overline y - \beta_1 \overline x[/tex]

replacing the values, we have:

[tex]\beta_o = 28 -(1.024)(17)[/tex]

[tex]\beta_o = 28 -17.408[/tex]

[tex]\beta_o = 10.592[/tex]

However, the regression line needed for this study can be computed as:

[tex]\hat Y = \beta_o + \beta_1 X[/tex]

[tex]\hat Y = 10.592 + 1.024 X[/tex]

Recall that;

both the weight and height roughly follow the normal curve

Thus, the weight related to 90th percentile can be determined as shown below.

Using the Excel Function at 90th percentile, which can be computed as:

(=Normsinv (0.90) ; we have the desired value of 1.28

[tex]\dfrac{X - \overline x}{s_x } = (Normsinv (0.90))[/tex]

[tex]\dfrac{X - \overline x}{s_x } = 1.28[/tex]

[tex]\dfrac{X - 17}{5} = 1.28[/tex]

[tex]X - 17 = 6.4[/tex]

X = 6.4 + 17

X = 23.4

The predicted height [tex]\hat Y = 10.592 + 1.024 X[/tex]

here; X = 23.4

[tex]\hat Y = 10.592 + 1.024 (23.4)[/tex]

[tex]\hat Y = 10.592 + 23.9616[/tex]

[tex]\hat Y = 34.5536[/tex]

So the probability of predicted height less than 34.5536 can be expressed as:

[tex]P(Y < 34.5536) = P( \dfrac{Y - \overline y }{S_y} < \dfrac{34.5536-28}{8})[/tex]

[tex]P(Y < 34.5536) = P(Z< \dfrac{6.5536}{8})[/tex]

[tex]P(Y < 34.5536) = P(Z< 0.8192)[/tex]

From the Z tables;

P(Y < 34.5536) =0.7937

Thus,  a turkey at the farm which weighs more than 90% of all the turkeys is predicted to be taller than 79.37 % of them.

The  average height for turkeys at the 90th percentile for weight is :

[tex]\hat Y = 10.592 + 1.024 X[/tex]

here; X = 23.4

[tex]\hat Y = 10.592 + 1.024 (23.4)[/tex]

[tex]\hat Y = 10.592 + 23.962[/tex]

[tex]\mathbf{\hat Y = 34.554}[/tex]

Of the turkeys at the 90th percentile for weight, roughly what percent would you estimate to be taller than 28 inches?

This implies that :

P(Y >28) = 1 - P (Y< 28)

[tex]P(Y >28) = 1 - P( Z < \dfrac{28 - 34.554}{8})[/tex]

[tex]P(Y >28) = 1 - P( Z < \dfrac{-6.554}{8})[/tex]

[tex]P(Y >28) = 1 - P( Z < -0.8193)[/tex]

From the Z tables,

[tex]P(Y >28) = 1 - 0.2063[/tex]

[tex]\mathbf{P(Y >28) = 0.7937}[/tex]

Answer:

125 cm and 75 cm

125:75 = 5:3

Step-by-step explanation:

Let the number be 5x and 3x

we are taking these value because in ratio

a:b = ax:bx

that is if we multiply both part of ratio by a same number ratio remains same.

____________________________________________________

Since we have divided 200 cm in two parts with value 5x and 3x

Thus,

sum of 5x and 3x will be equal to 200 cm

5x+3x = 200cm

8x = 200cm

x = 25 cm

Thus,

first part = 5x = 5*25 = 125 cm

There are 12 peaches in a bananas in a fruit basket you get a snack for yourself and three of your friends by choosing four of the pieces of fruit at random .what is the probability that all four peaches ?

Answers

Answer:

10.2% chance

Step-by-step explanation:

There are 12 peaches and 8 bananas for a total of 20 pieces of fruit.

So we can write it:

[tex]\frac{12}{20} * \frac{11}{19} * \frac{10}{18} * \frac{9}{17}[/tex] =  [tex]\frac{11880}{116,280}[/tex] = .102 or 10.2% chance

For ease multiply all numerators (top numbers) together, then multiply the denominators (bottom numbers) together, and then divide.

12 * 11 * 10 * 9 = 11880

20 * 19 * 18 * 17 = 116,280

We start with 12 peaches and 20 total fruit, as we select a peach the number of peaches and total fruit goes down by one. We do this 4 times because you draw 4 fruits. If you select 1 fruit your chances of it being a peach are 12/20, each time you select a fruit the chances of it being a peach go down because you have 1 less total fruit, and 1 less peach. This is why you multiply each probability together.

Answer:

10.2% probability

Step-by-step explanation:

12 peaches

8 bananas

Chance of getting a peach the first time is 12/20 the second time is 11/19, third 10/18, and fourth 9/17

11880/116280 = .1022 = 10.2% probability

The length of KL will be equivalent to 16.

What is the mid - point of the line segment?In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints. It bisects the segment.

Given is to that  KL = 4x - 8 and KM = 6x − 4

Since [M] is the midpoint, so we can write -

KL = (1/2)KM

(4x - 8) = (1/2)(6x - 4)

4x - 8 = 3x - 2

4x - 3x = 8 - 2

x = 6

KL = (1/2)(6 x 6 - 4)

KL = (1/2) x 32

KL = 16

The volume of the solid generated by revolving the plane region about the y-axis is approximately 6863.01 cubic units.

To use the shell method to find the volume of the solid generated by revolving the plane region about the y-axis, we need to express the limits of integration and the height of the infinitesimally thin cylindrical shells.

Given the equations:

y = x^(3/2)

y = 27

x = 0

To determine the limits of integration, we need to find the intersection points between the two curves: y = x^(3/2) and y = 27.

Setting the equations equal to each other:

x^(3/2) = 27

Taking the square root of both sides:

x = 27^(2/3)

x = 9

Therefore, the limits of integration are x = 0 and x = 9.

Now, let's consider an infinitesimally thin cylindrical shell with height "h" and radius "r" at some x value between 0 and 9.

The height of the shell, "h", is the difference between the y-values of the two curves:

h = 27 - x^(3/2)

The radius of the shell, "r", is the x-value.

The volume of the shell can be expressed as:

dV = 2πrh dx

To find the total volume, we integrate this expression from x = 0 to x = 9:

V = ∫[0, 9] 2π(27 - x^(3/2))x dx

Now, let's evaluate this integral:

V = 2π ∫[0, 9] (27x - x^(5/2)) dx

Integrating term by term:

V = 2π [(27/2)x^2 - (2/7)x^(7/2)] evaluated from 0 to 9

Plugging in the limits of integration:

V = 2π [(27/2)(9)^2 - (2/7)(9)^(7/2)] - 2π [(27/2)(0)^2 - (2/7)(0)^(7/2)]

Simplifying and evaluating the expression:

V = 2π [(27/2)(81) - (2/7)(3√(9))] - 0

V = 2π [1093.357] ≈ 6863.01 cubic units

Central Park in New York City is shaped like a rectangle. On a map of the park in the coordinate plane, three of the vertices are located at (-1.25,-0.25) (-1.25, 0.25), and (1.25, 0.25). Distances on the map are in miles. What is the perimeter of Central Park? Show your work.

Answers

Answer: P = 6 miles

Step-by-step explanation: A rectangle is a quadrilateral with opposite sides with the same measure. As Central Park is one, its parallel sides has the same measurement.

Distance of points gives the measurement of the sides of the rectangle. It is calculated as:

[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }[/tex]

For the first two points, (-1.25,-0.25) and (-1.25,0.25), note that x-components is the same, so, only y-component is relevant to the distance:

[tex]d=\sqrt{(-1.25+1.25)^{2}+(0.25+0.25)^{2} }[/tex]

[tex]d=\sqrt{(0.5)^{2} }[/tex]

d = 0.5

Two sides of the rectangle are 0.5 miles.

For points (-1.25,0.25) and (1.25,0.25), y-component will add 0 to the formula. Then,

[tex]d=\sqrt{(1.25+1.25)^{2}+(0.25-0.25)^{2} }[/tex]

[tex]d=\sqrt{(2.5)^{2}}[/tex]

d = 2.5

Two sides of the park are 2.5 miles.

Perimeter is the sum of all the sides of a geometric figure.

Perimeter of central Park is

P = 0.5+0.5+2.5+2.5

P = 6

Central Park has perimeter of 6 miles.

Answers

Answer:

1, 4, 9, 16, 25, 36, 49, 64, 81, and 100

Step-by-step explanation:

Let's pretend that the locker number is represented as a Binary (meaning it's either open or closed).

Looking at this, we can see that each locker is only acted upon if the student number is a factor of it. This is why the 3rd person changes the state of every 3 lockers, the 4th student changes the state of every 4 lockers, etc.

The factors of a number are the numbers that the original number is evenly divisible by. When we divide these, we also receive a factor. With this information, we can conclude that unless one of the factors is the square root of the number, then the "second divided by" factor is itself. For every other number, there will be a "second divided by" factor, so an even number of them. Because an even number + 1 = odd number, then only perfect squares will have an odd number of factors.

Since 4 is a multiple of 1, 2, and 4, it is changed by the 1st, 2nd, and 4th students. Since there is an odd number (3) of changes, locker 4 stays open.

Observe that a locker at position n is opened by students with factors of n.

Every number can be written as the product of a pair of distinct numbers except perfect squares. For example, 6 can be written as 1 × 6 and 2 × 3. Hence, it has 4 factors, which means it is touched an even number of times, making it stay locked.

A number like 9 is written as 1 × 9 and 3 × 3. Hence, it has 3 factors, which is odd, making it stay open.

Since the perfect squares from 1 to 100 are 1,4,9,16,25,36,49,64,81,100, then the open lockers are:

1,4,9,16,25,36,49,64,81,100

Triangle ABC has side lengths of 3 and 10. What are the restrictions on the third side?​

Answers

Answer:

  7 < third side < 13

Step-by-step explanation:

The triangle inequality requires the sum of the shortest two side lengths to be more than the longest side length. The effect of that is to limit the third side to values between the sum and difference of the other two sides:

  7 < third side < 13

Which trigonometric inequality has no solution over the interval 0<=x<=2 a. csc(x)1>0 b.cos(x)-1>0 c.cot(x)-1>0 d.tan(x)-1>0

Answers

Answer:

B

Step-by-step explanation:

a. csc x − 1 > 0

csc x > 1

sin x < 1

x = [0, π/2) U (π/2, 2]

b. cos x − 1 > 0

cos x > 1

x = no solution

c. cot x − 1 > 0

cot x > 1

tan x < 1

x = [0, π/4) U (π/2, 2]

d. tan x − 1 > 0

tan x > 1

x = (π/4, π/2) U (π/2, 3π/4)

Of the 4 options, only B has no solution.

The only inequality that does not have a solution with the range is option B;  cos x − 1 > 0.

What is inequality?

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

A. csc x − 1 > 0

csc x > 1

sin x < 1

x = [0, π/2) U (π/2, 2]

B. cos x − 1 > 0

cos x > 1

x = no solution

C. cot x − 1 > 0

cot x > 1

tan x < 1

x = [0, π/4) U (π/2, 2]

D. tan x − 1 > 0

tan x > 1

x = (π/4, π/2) U (π/2, 3π/4)

Therefore option B is the only inequality that does not have a solution with the range.

Step-by-step explanation:

Keith received a gift card of $90 for a pizza restaurant. The restaurant charges $15 per pizza. Mary received a gift card of $110 for a different pizza restaurant. The restaurant charges $20 per pizza.
Let x be the number of pizzas purchased. For each card, write an expression for the amount of money left on the card after purchasing x pizzas.
Amount of money left on Keith's card in dollars = __________
Amount of money left on Mary's card in dollars=____________
Write an equation to show that the two cards have the same amount of money left on them [don't know how to do this part.

Answers

Answer:

a)Amount of money left on Keith's card in dollars = $90 - $15x

= $(90 - 15)

b) Amount of money left on Mary's card in dollars= $110 - $20x

= $(110 - 20x)

c) Write an equation to show that the two cards have the same amount of money left on them [don't know how to do this part.

$90 - 15x = $110 - 20x

Step-by-step explanation:

Let x be the number of pizzas purchased. For each card, write an expression for the amount of money left on the card after purchasing x pizzas.

For Keith

Keith received a gift card of $90 for a pizza restaurant. The restaurant charges $15 per pizza.

x numbers of pizza costs = $15x

Hence, the amount of money left on Keith's card after purchasing x pizzas =

$90 - $15x

For Mary,

Mary received a gift card of $110 for a different pizza restaurant. The restaurant charges $20 per pizza.

Hence, x number of pizzas cost =$20 × x

= $20x

Therefore, the amount of money left on Mary's card after she buys x pizzas =

$110 - $20x

Amount of money left on Keith's card in dollars = __________

Amount of money left on Mary's card in dollars=____________

Write an equation to show that the two cards have the same amount of money left on them [don't know how to do this part.

To find the equation that shows that the two cards have the same amount of money =

Equation 1 = Equation 2

$90 - 15x = $110 - 20x

Collect like terms

-15x + 20x = $110 - $90

5x = 20

x = 20/5

x = 4

Hence, anytime Keith and Mary buys 4 pizzas their gift card will have the same amount of money left on them.

g 1.32 Two points on a sphere of radius 3 are given as P1(3,0,30) and P2(3,45,45): (a) Find the position vectors of P1 and P2. (b) Find the vector connecting P1 (tail) to P2 (head). (c) Find the position vectors and the vector P1P2 in cylindrical and Cartesian coordinates.

Answers

Answer:

a) P.V  of is OP₁ = [ 1.5i + 0j + 2.6k ],   P.V  of is OP₂ = [ 1.5i + 1.5j + 2.12k ]

b) Vector connecting P₁ to P₂ is [ 0i + 1.5j + 0.48k ]  

c) cylindrical coordinates are (1.5, π/2, 0.48)

Step-by-step explanation:

Given that;

r = 3

P₁ ( 3, 0°, 30° ),   P₂ ( 3, 45°, 45° )

a)

P.V of P₁

x = rcos∅sin∅ = 3(cos0°) ( sin30°) = (3 × 1 × 0.5) = 1.5

y = rsin∅sin∅  = 3(sin0°) (sin30°)   = (3 × 0 × 0.5) = 0

z = rcos∅        = 3(cos30°)             = ( 3 × 0.866)  = 2.6

∴ P.V  of is OP₁ = [ 1.5i + 0j + 2.6k ]

P.V of P₂

x = rcos∅sin∅ = 3(cos45°) ( sin45°) = (3 × 0.7071 × 0.7071) = 1.5

y = rsin∅sin∅  = 3(sin45°) (sin45°)   = (3 × 0.7071 × 0.7071) = 1.5

z = rcos∅        = 3(cos45°)                 = ( 3 × 0.7071)            = 2.12

P.V  of is OP₂ = [ 1.5i + 1.5j + 2.12k ]

b)

Vector connecting P₁ to P₂ is given by

OP₂ - OP₁ = [ 1.5i + 1.5j + 2.12k ] - [ 1.5i + 0j + 2.6k ]

= [ 0i + 1.5j + 0.48k ]  

c)

P₁P₂ → = [ 0i + 1.5j + 0.48k ]  = [ 1.5j + 0.48k ]  

so in a cylindrical coordinate, it should be

r = √(o² + 1.5²) = 1.5

∅ = tan⁻¹[y/π] = π/2

z = 0.48

cylindrical coordinates are (1.5, π/2, 0.48)
