Answer:

Following are the responses to the given question:

Step-by-step explanation:

Level of Significance,\alpha =    0.05

Sample Size, n =    120          

Sample Proportion,   \hat{P} = 0.600      

z -value =   Z_{\frac{\alpha}{2}} =  1.960  \ \  [excel formula =NORMSINV(\frac{\alpha}{2})]

Standard ErrorSE = \sqrt{\frac{\hat{p}(1-\hat{p})}{n}} =    0.0447        

margin of error E = Z\times SE =    1.960   \times   0.0447   =   0.0877

When 95\% Confidence Interval              

Interval Lower Limit= \hat{p} - E =    0.600   -   0.0877   =   0.5123

Interval Upper Limit =\hat{p}+ E =   0.600   +   0.0877   =   0.6877

Lynna [10]
Hey You!

132*42% = 55.44

132 - 55.44 = 76.56

So, the Millers paid $55.44 for gas and $76.56 for electricity.

Hi! Can someone help me please.
Sati [7]

Answer:

27 inches

Step-by-step explanation:

We are using the Pythagorean theorem

a^2 +b^2 = c^2  where c is the hypotenuse

We are given the diagonal, which is the hypotenuse and a leg

36^2 + b^2 = 45^2

Subtract 36^2 from each side

36^2 + b^2 - 36^2 = 45^2 - 36^2

b^2 = 45^2 - 36^2

     b^2 =2025-1296

          b^2 =729

Take the square root of each side

sqrt(b^2) = sqrt(729)

b =27
