Answer:

0.1587

Step-by-step explanation:

Given the following :

Mean (m) of distribution = 64 inches

Standard deviation (sd) of distribution = 2 inches

Probability that a randomly selected woman is taller than 66 inches

For a normal distribution :

Z - score = (x - mean) / standard deviation

Where x = 66

P(X > 66) = P( Z > (66 - 64) / 2)

P(X > 66) = P(Z > (2 /2)

P(X > 66) = P(Z > 1)

P(Z > 1) = 1 - P(Z ≤ 1)

P(Z ≤ 1) = 0.8413 ( from z distribution table)

1 - P(Z ≤ 1) = 1 - 0.8413

= 0.1587

*Complete Question:

Given the diagram below, where and mDE = 105^ and mGE = 125^ Find m<DEG

Answer:

m<DEG = 65°

Step-by-step explanation:

Angle DEG is an inscribed angle that intercepts the DG. Based on the theorem of inscribed angles, angle DEG = ½ of the measure of arc DG.

To find the measure of angle DEG, find the measure of arc DG first.

Measure of arc DG = 360° - (105° + 125°) => a full circle measures 369°

Arc DG = 360° - 230 = 130°.

m<DEG = ½ of 130° = ½*130° = 65°

Answer:

2.6

Step-by-step explanation:

From the image attached, the diameter of the inner semi - circle is 0.5 yards while the length of each side of the pillow is 0.2 yards.

Thus, for us to find the length of the seam which is along the edges of the pillow, we will calculate the perimeter of the outer semicircle, then add the perimeter of the inner semicircle and also add the sides too.

Now, due to the fact that the length of the sides of the pillow are 0.2 yards each, the diameter of the outer circle would be;

0.5 + 0.2 + 0.2 = 0.9 yards. So, the perimeter of the outer semicircle is,

P0 = πd/2 = π × 0.9/2 =0.45π yds

The perimeter of the inner semicircle would be given as;

PI = πd/2 = π × 0.5/2 =0.25π yds.

Thus, we can calculate the total perimeter of the pillow as;

PT = P0 + PI + 0.2 + 0.2

PT = 0.45π + 0.25π + 0.2 + 0.2

PT ≈ 2.6 yards

Answer:

[tex]\huge\boxed{a=9 ; b = -8}[/tex]

Step-by-step explanation:

[tex]f(x) = \frac{ax+b}{x}[/tex]

Putting x = 1

=> [tex]f(1) = \frac{a(1)+b}{1}[/tex]

Given that f(1) = 1

=> [tex]1 = a + b[/tex]

=> [tex]a+b = 1[/tex]  -------------------(1)

Now,

Putting x = 2

=> [tex]f(2) = \frac{a(2)+b}{2}[/tex]

Given that f(2) = 5

=> [tex]5 = \frac{2a+b}{2}[/tex]

=> [tex]2a+b = 5*2[/tex]

=> [tex]2a+b = 10[/tex]  ----------------(2)

Subtracting (2) from (1)

[tex]a+b-(2a+b) = 1-10\\a+b-2a-b = -9\\a-2a = -9\\-a = -9\\a = 9[/tex]

For b , Put a = 9 in equation (1)

[tex]9+b = 1\\Subtracting \ both \ sides \ by \ 9\\b = 1-9\\b = -8[/tex]

Hi, I'm happy to help!

Parallel means that two lines are lined up in the same directions and will never intersect even if they were extended forever in directions.

Let's look at the first option of AB, and AD. We can see that both lines intersect at point A, so AB and AD are not parallel.

For the next option of CD and BE, we can see that both lines don't intersect and won't ever even if the lines were extended. So, CD and BE are parallel.

For the third option, we have BC and DE. These lines don't intersect and aren't in line to ever do so. Therefore, BC and DE and parallel.

The last option is AD and BC. These two lines will never meet, but, they aren't line up in the same directions. AD is traveling upwards while BC isn't. Think about being able to make a road out of the two lines, it would never work. AD and BC are not parallel.

To sum it up: You should select the 2nd and 3rd options because those lines are parallel.

The value of the function (f -g)(x) will be 2x^3 + 7x^2 - 7x - 3

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable, Linear function is a function whose graph is a straight line

We are given that the function as;

[tex]f(x) = 2x^3 + 7x^2 - 4x - 5[/tex]

[tex]g(x) = 3x - 2[/tex]

We need to find the function as (f - g)(x)

(f -g)(x) = f(x) -g(x)

(f -g)(x) = 2x^3 + 7x^2 - 4x - 5 - 3x + 2

(f -g)(x) = 2x^3 + 7x^2 - 7x - 3

Therefore, the correct option is C 2x^3 + 7x^2 - 7x - 3

Z > ± 1.645

z= 3.968

Step-by-step explanation:

We formulate the null and alternate hypotheses as

H0 =μ2 ≥ μ1   Ha: μ2  <μ1  one sided

Let α= 0.05

Since the sample sizes are large therefore the test statistic used under H0 is

The critical region for α= 0.05 for a one tailed test Z > ± 1.645

Z = (x`2- x`1) /s/ √n

Z= 154.8-128.746.5/√50

z= 26.1/6.577

z= 3.968

Since the calculated value of z lies in the critical region we reject H0 that internet users spend more time  or equal time.

Answer:

m∠AOD = 140°

Step-by-step explanation:

In the diagram attached,

OA⊥OC and OB⊥OD

m∠AOD = 3.5(m∠BOC)

Since, m∠BOD = 90°  [Given: OA⊥OC]

m∠BOC + m∠COD = 90° ---------(1)

Similarly, m∠AOC = 90° [Given : OA⊥OC]

m∠AOB + m∠BOC = 90° --------(2)

Equation (1) - Equation(2)

(m∠BOC + m∠COD) - (m∠AOB + m∠BOC) = 90°- 90°

m∠COD = m∠AOB

m∠AOB + m∠BOC + m∠COD = m∠AOD --------(3)

m∠AOB + m∠BOC + m∠AOB = 3.5(m∠BOC) [Since m∠COD = m∠AOB]

2m∠AOB = 3.5(m∠BOC) - m∠BOC

2m∠AOB = 2.5(m∠BOC)

m∠AOB = 1.25(m∠BOC)

From equation (2),

m∠AOB + m∠BOC = 90°

1.25(m∠BOC) + m∠BOC = 90°

2.25(m∠BOC) = 90°

m∠BOC = 40°

From equation (1),

m∠BOC + m∠COD = 90°

m∠COD + 40° = 90°

m∠COD = 50°

Now by putting these values in equation (3)

m∠AOB + m∠BOC + m∠COD = m∠AOD

m∠COD + m∠BOC + m∠COD = m∠AOD

50° + 40° + 50°= m∠AOD

m∠AOD = 140°

Explanation:

Subtracting a negative is the same as adding. Example: 2-(-3) = 2+3 = 5.

So (x+y)-(-z) is the same as x+y+z. We can group up terms inside parenthesis and it won't change the result. Meaning that x+y+z is the same as any of the following below

We could also swap the order of either x, y or z, and still have the same result.

∠A and ∠G is the pair of vertical angles.

Step-by-step explanation:

From the figure attached,

Two lines 'm' and 'n' are two parallel lines. These lines intersect a horizontal line 'l'.

Since, "Pair of opposite angles formed at the point of intersection are the vertical angles and equal in measure."

Therefore, Opposite angles ∠A ≅ ∠G, ∠B ≅ ∠H, ∠C ≅ ∠E and ∠D ≅ ∠F are the vertical angles.

From the given options,

∠A and ∠G is the pair representing the pair of vertical angles and thus congruent.
