Step-by-step explanation:

As per the question, the values are:

Credit hours                                       Grade                                 fiXi

       (fi)                                                   (Xi)                              

        4                                                  B = 3                                   12

        3                                                  C = 2                                   6

        1                                                   A = 4                                   4

        3                                                  D = 1                                    3      

Now,

[tex]\Sigma fi= 25[/tex]

[tex]\Sigma fiXi = 25[/tex]

hence,

The average will be:

= [tex]\frac{\Sigma fiXi}{\Sigma fi}[/tex]

On putting the values, we get

= [tex]\frac{25}{11}[/tex]

= [tex]2.27[/tex]                              

Answer:

The answer is "0.3206".

Step-by-step explanation:

[tex]H_0: p_1 = p_2\\\\H_a: p_1 \neq p_2\\\\\hat{p_1} = \frac{X_1}{N_1} = \frac{53}{400} = 0.1325\\\\\hat{p_1}= \frac{X_2}{N_2} = \frac{78}{500}= 0.156\\\\\hat{p} = \frac{(X_1 + X_2)}{(N_1 + N_2)} = \frac{(53+78)}{(400+500)} = 0.1456[/tex]

Testing statistic:

[tex]z = \frac{(\hat{p_1}- \hat{p_2})}{\sqrt{(\hat{p} \times (1-\hat{p}) \times (\frac{1}{N_1} + \frac{1}{N_2}))}}[/tex]

[tex]=\frac{(0.1325-0.156)}{\sqrt{(0.1456\times (1-0.1456)\times (\frac{1}{400} + \frac{1}{500}))}}\\\\ = -0.99[/tex]

Calculating the P-value Approach

[tex]\text{P-value}= 0.3206[/tex]

Answer:

x = 66

Step-by-step explanation:

Remark

98 is an exterior angle. Exterior angles are the sum of the two remote interior angles. The remote interior angles have 2 properties

It's much easier just to make an equation.

x + 32 = 98             Subtract 32 from each side

Answer:

A

Step-by-step explanation:

There is an x in all for terms that means that x = 0 is one of the factors and H is incorrect.

One of the remaining factors is x^2 - 9 which factors into (x - 3)(x + 3)

You are told that x = 1  is a zero which means x - 1 is a factor.

The answer is g(x) = x (x - 3)(x + 3) (x - 1) which is A

The equation that best represents the inverse variation between A and n is: D. 2,000 = An

The equation that models an inverse variation between two variables, x and y, is: k = xy, where k is a constant value.

Given the following:

Substitute the values into k = xy:

2,000 = An

The equation is: 2,000 = An

Step-by-step explanation:

Answer:

600% of 12 is 72.

Step-by-step explanation:

[tex]\frac{72}{y}: \frac{600}{100}[/tex]

y · 600 = 72 · 100

600y = 7200

600y ÷ 600 = 7200 ÷ 600

Answer:

A

Step-by-step explanation:

Given p² varies inversely as q then the equation relating them is

p² = [tex]\frac{k}{q}[/tex] ← k is the constant of variation

To find use the condition when q = 6, p = 4 , then

4² = [tex]\frac{k}{6}[/tex]

16 = [tex]\frac{k}{6}[/tex] ( multiply both sides by 6 )

96 = k

p² = [tex]\frac{96}{q}[/tex] ← equation of variation

When p = 12 , then

12² = [tex]\frac{96}{q}[/tex] ( multiply both sides by q )

144q = 96 ( divide both sides by 144 )

q = [tex]\frac{96}{144}[/tex] = [tex]\frac{2}{3}[/tex] → A
