Answer:

The power of the test will be highest for;

C. The sample size is n = 1,000, and 55 percent of all students actually use vending machines

Step-by-step explanation:

For a large sample test for proportions, we have;

[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p \cdot q}{n}}}[/tex]

Where;

[tex]\hat p[/tex] = The percentage of the hypothesized proportion = 20% = 0.20

p = The actual proportion

n = The size of the sample

The power of the test increases when;

The sample size 'n' is large

When the true vale of the measured items in the test is much larger than the value set as the null hypothesis

When the significant level is high

Therefore, we have;

The power of the test will be highest when the sample size is n = 1,000, and 55 percent of all students actually use vending machines

Answer:

[tex]\frac{29}{72}[/tex]

Step-by-step explanation:

There are 360° in one complete rotation , thus angle turns

fraction = [tex]\frac{145}{360}[/tex] ( divide numerator and denominator by 5 )

             = [tex]\frac{29}{72}[/tex] ← in simpest form

Answer: One

Step-by-step explanation:

Answer:

x = 20°

Step-by-step explanation:

here's your solution

=> it is given that whole angle is 90°

=> so, x + (3x + 10) = 90°

=> x + 3x + 10 = 90°

=> 4x + 10 = 90°

=>4x = 90 - 10

=> 4x = 80°

=.

=> x = 80/4

=> x = 20°

one angle is 20° and other 70°

hope it helps

Answer:

20 is your answer

x+3x+10=90 being right angle

4x=90-10

x=80/4=20

cost of T- shirts = 125 (Fixed price) + 15* number of T- shirts

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

A school pays a company $125 to design gym T-shirts.

It costs an additional $15 to make each T-shirt.

Number of T-Shirts         Cost ($)

             0                             125

              5                            200

              10                           275

              15                           350

b) equation:

    cost of T- shirts = 125 (Fixed price) + 15* number of T- shirts

c) cost of  378 T- shirts

    =125+ 15(378)

    = 5795

c) school store has a budget of $2345

    Number of T- shirts = (2345-125)/15

                                      = 148 T- shirts

Complete Question:

g(x), represents transformations on the parent function of [tex]y = (\frac{1}{2})^x[/tex].

Write the equation for g (x ) with the following transformations:

Reflect over y-axis, and shift right 7

Answer:

[tex]g(x) = (\frac{1}{2})^{-x-7}[/tex]

Step-by-step explanation:

Given

[tex]y = (\frac{1}{2})^x[/tex]

Represent the function as:

[tex]f(x) = (\frac{1}{2})^x[/tex]

Taking the transformations, one after the other:

Reflect over the y-axis.

This is represented by the rule: (x,y) ==> (-x,y)

So, we have:

[tex]f'(x) = (\frac{1}{2})^{-x}[/tex]

Shift right 7 units

This is represented by (x,y) = (x - b, y)

Where b represents the number of units

So, we have:

[tex]f'(x-7) = (\frac{1}{2})^{-x-7}[/tex]

Hence:

[tex]g(x) = (\frac{1}{2})^{-x-7}[/tex]

Answer:

2 docenas cuestan $61.200.

Step-by-step explanation:

Para encontrar la respuesta, debes considerar que una docena equivale a 12 artículos, por lo cual tienes que multiplicar 12 por 2 para encontrar el número de rosas en 2 docenas:

12*2=24

Ahora, dado que sabes que una rosa cuesta $2.550 tienes que multiplicar este valor por 24 para encontrar cuanto cuestan 2 docenas:

$2.550*24=$61.200

De acuerdo a esto, la respuesta es que 2 docenas cuestan $61.200.

Answer:

x = -5

y = -1

Step-by-step explanation:

Y= -6/5x-7 and y=2/5x+1

then:

-6/5x - 7 = 2/5x + 1

simplify:

-8/5x = 8

divide both sides by 8:

-1/5x = 1

multiply both sides by 5:

-x = 5

x = -5

y = 2/5(-5) + 1 = -2 + 1 = -1

Given:

The limit problem is:

[tex]\lim_{x\to 3}(x^2+8x-2)[/tex]

To find:

The limit of the function by using direct substitution.

Solution:

We have,

[tex]\lim_{x\to 3}(x^2+8x-2)[/tex]

Applying limit, we get

[tex]\lim_{x\to 3}(x^2+8x-2)=(3)^2+8(3)-2[/tex]

[tex]\lim_{x\to 3}(x^2+8x-2)=9+24-2[/tex]

[tex]\lim_{x\to 3}(x^2+8x-2)=33-2[/tex]

[tex]\lim_{x\to 3}(x^2+8x-2)=31[/tex]

Therefore, the correct option is D.
