Step-by-step explanation:

sorry jesica I don't know the answer

its hard to explain and show work but so you know the answer is no and its because they converted yards to miles and did the formula for ft to miles instead of yd to miles they did 5280 ft per mile and not 1760 yd per miles

Answer:

13.63 miles per hour

Step-by-step explanation:

100 yards / 15 sec  converted to miles per hour

100 yards  x  60 sec  x   60 min   x  1 mile       =  13.63 miles/hr

   15 sec           1 min            1 hr         1760 yards

the mistake on Mrs Dukes is the conversion from miles to yards.

1 mile = 1760 yards NOT 5280 yards

Answer:

[tex]A(-1,-8)[/tex]

Step-by-step explanation:

Given

Point: A(2,6)

Translation: 1 left and 3 up

Rotation: 180 degrees

Required

Image of Point A

Taking the exercise one after the other

Represent the function as: (x,y)

Such that

[tex]A(x,y) = A(2,6)[/tex]

1 unit left translation means the function becomes (x - 1, y)

2 unit up translation means the function becomes (x - 1, y + 2)

Applying the above transformation

[tex]A(2,6) -> A(2-1,6+2)[/tex]

[tex]A(2,6) -> A(1,8)[/tex]

At this stage, the coordinate becomes

[tex]A(1,8)[/tex]

When a function (x,y) is rotated by 180, the new function becomes (-x,-y)

So;

The further transformation of A is

[tex]A(1,8) -> A(-1,-8)[/tex]

Hence, the new image of A is

[tex]A(-1,-8)[/tex]

(Really hoping this helps <3)

Answer:

Step-by-step explanation:

Given the vectors ⟨−39,b,3⟩ and ⟨b,b²,b⟩, for the vectors to be orthogonal, the dot product of both vectors must be equal to zero.

Taking the dot product of both vectors and equating it t zero we will have;

⟨−39,b,3⟩*⟨b,b²,b⟩ = -39(b)+ b(b²)+3(b)

(Note that when multiplying, we multiply component wise and take the sum of the product if each component)

Since the vectors are orthogonal, then -39(b)+ b(b²)+3(b) = 0

open the parenthesis

-39b+b³+3b = 0

on rearranging

b³+3b-39b= 0

b³-36b= 0

factor out b from the equation

b(b²-36) = 0

b = 0 and b²-36 = 0

from b²-36 = 0

add 36 to both sides of the equation

b²-36+36= 0+36

b² = 36

take the square root of both sides

√b² = ±√36

b = ±6

Hence the values of b for the vectors to be orthogonal are 0, -6 and 6.

Answer:

3 ; 4.5 ; 7.25

Step-by-step explanation:

Given the sample :

8 2 9 5 3 7 4 2 7 4 10 4 3 5

Calculate, the first, second, and third quartiles

Arranging the data in ascending order :

2, 2, 3, 3, 4, 4, 4, 5, 5, 7, 7, 8, 9, 10

First quartile :

Q1 = [(n + 1) /4]th value

n = 14

Q1 = [(14 + 1) /4]th = (15/4)th = 3.75 value

Taking the average of the 3rs and 4th observation:

(3 +3) / 2 = 3

Second quartile :

Q2 = [2(n + 1) /4]th value

Q2 = 2(15)/4 = (30/4)th value

Q2 = 7.5 ; taking the 7th and 8th value

Q2 = (4 +5) /2 = 9/2 = 4.5

Q3 = [3(n + 1) /4]th value

Q2 = 3(15)/4 = (45/4)th value

Q2 = 11.25 ; taking the 11th

Q2 = 7 + 0.25 = 7.25

Answer:

Step-by-step explanation:

Initial ratio of maple trees to oak trees

New ratio  of maple trees to oak trees

Number of oak trees = 132

Number of maple trees

Total number of trees

Initial number of maple trees

The difference in the number of maple trees:

Answer:

72 more trees before the bug problem

Step-by-step explanation:

The ratio was 9:5 before the bug problem and 3:11 after.

After the bug problem there were 132 oak trees,

m : 132 = 3 : 11

Then we know

m/132 = 3/11

Multiplying both sides by 132 cancels on the left

132 × (m/132) = (3/11) × 132

m = (3/11) × 132

Then solving for m

m = 132 × (3/11)

m = 36   This gives us the number of trees after the bug problem.

This would give us 168 trees in total, 132 oak, and 36 maple.

Since there is the same number of trees as before we calculate the number of maple and oak previously.

If Shelley counted 9 maple for every 5 oak we know that 9 out of 14 trees are maple and 5 out of 14 trees are oak.

9/14 = .6428 which is the percentage of maple trees before the bug problem.

We multiply .6428 x 168 (the total number of trees) and we get 108.

if there are 108 maple trees then 168-108 = 60 oak trees.

Further proof:

9:5 or 9/5 = 1.8     108/60 = 1.8

108 maple trees and 60 oak before the bug problem.

So 108 (maple before bug problem) and 36 maple trees after:

108 - 36 = 72 more trees before the bug problem

Answer:

The  value is  [tex]k = 3 \ inches[/tex]

Step-by-step explanation:

From the question we are told that

   The  length is   [tex]l = 25 \ ft[/tex]

   The  width is  [tex]w = 12 \ inches = \frac{12}{12} = 1\ ft[/tex]

Generally let assume that (k ft)  was turned up on each side hence the remaining width is  

             [tex](1 - 2 k ) \ ft[/tex]

Now  the capacity is also the volume it can hold which is mathematically represented as

         [tex]C = 25 (1- 2k) k[/tex]

          [tex]C = 25 (k- 2k^2)[/tex]

          [tex]C = 25k - 50k^2[/tex]

At maximum  or minimum  

     [tex]\frac{dC}{dk} = 0[/tex]

=>    [tex]\frac{dC}{dk} = 25 - 100k = 0[/tex]

=>    [tex]k = 0.25\ ft[/tex]

Now  to see if the value  obtained is positive or negative we differentiate a second time

    So

        [tex]\frac{d^2C}{dk^2} = - 100k[/tex]

at  k  =  0,25 ft

       [tex]\frac{d^2C}{dk^2} = - 100(0.25)[/tex]

       [tex]\frac{d^2C}{dk^2} = -25[/tex]

since a negative  value is obtained then k is  the maximum value  

converting to inches

     [tex]k = 0.25 * 12[/tex]

     [tex]k = 3 \ inches[/tex]

Answer:

Rylee spent $25 for fuel at the gas station. This money is leaving her bank account, so represent the amount with a negative sign: -$25.

Step-by-step explanation:

None. the expression explains it.

It does not deal with numeric values, but rather we're talking about names or labels when we are talking about nations of origin. This variable is categorical and nominal. It is not ordinal as we cannot order the nations in any way. You could argue about alphabetical ordering of course, but that won't apply here because you could do that about any set of labels (eg: colors red,green,blue can be ordered alphabetically but intrinsically it doesn't make sense to sort colors).

Since "nation of origin" involves categories or labels representing different countries, it is considered a qualitative variable.

We have,

Qualitative variables, also known as categorical variables, represent characteristics or qualities that cannot be measured numerically.

These variables typically involve categories or labels that describe different groups or attributes.

In the case of "nation of origin," it refers to the country from which someone originates.

This variable is qualitative because it involves different categories or labels representing different nations or countries.

Examples of possible categories for nation of origin include "United States," "Canada," "France," "China," and so on.

Therefore,

Since "nation of origin" involves categories or labels representing different countries, it is considered a qualitative variable.

Answer:

  4.32%; no

Step-by-step explanation:

The value of 0.24 differs from the mean by 0.84 -0.24 = 0.60. 2 standard deviations from the mean would be a difference of 2×0.35 = 0.70.

A statistical calculator says the probability of a depth less than 0.24 mm for the given distribution is about 4.32%.

The value differs from the mean by less than 2 standard deviations, so is not considered unusual.

Answer:

degrees of freedom = 15

tc= 1.746

Step-by-step explanation:

The degrees of freedom is given by n-1 where n is the sample size .

so the degrees of freedom for a t distribution is 16-1= 15

Now we have to find tc for 95%  confidence interval. For this we look at the t- table under the 1-0.95= 0.05  for alpha for 15 degrees of freedom and the value is 1.746

This area is to  the right side under the t distribution with the given degrees of freedom for the given alpha.

It can also be found out by other calculators such as graphing calculator.

Using the degree of freedom formula and the Tcritical distribution, the degree of freedom and Tcritical value are 15 and 2.131 respectively

Given that :

Hence, the degree of freedom, df = 16 - 1 = 15

The t critical value :

Tcritical = [tex]t_{\frac{0.05}{2}}, 15 = 2.131 [/tex]

Hence, the Tcritical value is 2.131.
