Suppose you want to estimate the proportion of cars that are sport utility vehicles (SUVs) being driven in Kansas City, Missouri

ahrayia [7]

Answer:

The sample size 'n' = 721

Number of cars 'n' = 721

Step-by-step explanation:

Explanation:-

Given Population proportion 'p' = 0.40

Given Margin of error = 0.03

90% of level of significance

$Z_{\frac{\alpha }{2} } = 1.645$

The Margin of error is determined by

$M.E = \frac{Z_{\frac{\alpha }{2} S.D} }{\sqrt{n} }$

$0.03 = \frac{1.645 X \sqrt{0.40(1-0.40) } }{\sqrt{n} }$

on calculation , we get

0.03√n = 0.8058

$\sqrt{n} = \frac{0.8058}{0.03} = 26.86$

squaring on both sides , we get

n = 721.45≅721

conclusion:-

The sample size 'n' = 721

Number of cars 'n' = 721

Find the inverse of the following function.

Naddik [55]

For this case we must find the inverse of the following function:

$f (x) = 8 \sqrt {x}$

For this, we follow the steps below:

We change f (x) to y:

$y = 8 \sqrt {x}$

We exchange the variables:

$x = 8 \sqrt {y}$

We solve for y:

$8 \sqrt {y} = x$

We divide between 8 on both sides of the equation:

$\sqrt {y} = \frac {x} {8}$

We raise both sides of the equation to the square to remove the root:

$y = (\frac {x} {8}) ^ 2\\y = \frac {x ^ 2} {64}$

So, the inverse is: $f ^ {- 1} (x) = \frac {x ^ 2} {64}$

A cookie recipe for three dozen Caramel peanut butter bars uses 14oz of caramel. How much caramel (to the nearest ounce) should

tia_tia [17]

140oz I believe because you just do 14oz times 10 because one dozen is 12 and 12 times 10 is 120.
