Assume that women's heights are normally distributed with a mean given by mu equals 62.5 in, and a standard deviation given by

kirza4 [7]

Answer: a) The probability is approximately = 0.5793

b) The probability is approximately=0.8810

Step-by-step explanation:

Given : Mean : $\mu= 62.5\text{ in}$

Standard deviation : $\sigma = \text{2.5 in}$

a) The formula for z -score :

$z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

Sample size = 1

For x= 63 in. ,

$z=\dfrac{63-62.5}{\dfrac{2.5}{\sqrt{1}}}=0.2$

The p-value = $P(z$

$0.5792597\approx0.5793$

Thus, the probability is approximately = 0.5793

b) Sample size = 35

For x= 63 ,

$z=\dfrac{63-62.5}{\dfrac{2.5}{\sqrt{35}}}\approx1.18$

The p-value = $P(z$

$= 0.8809999\approx0.8810$

Thus , the probability is approximately=0.8810.

kobusy [5.1K]

Answer:

answer below

Step-by-step explanation:

I think you mean "squashed" or "stretched" vertically by a factor of 5.

f(x) is the original parabola equation

g(x) = 5f(x) is vertically stretched by a factor of 5

(x,y) -> (x , 5y)

Calculate the taxes based on the following taxable income amounts

Bingel [31]

1.) Taxable income is 22,764.42 (income 90,714 less range which is more than 87,850 but less than 183,250 = 2,864 multiply to its corresponding tax rate of 28% = 801.92 plus its corresponding amount of 21,962.50 = 22,764.42)

2.) Taxable income is 12,140.75

3.) Taxable income is 63,634.18

4.) Taxable income is 44,097.62

5.) Taxable income is 63,691.60

6.) Taxable income is 24,598.98

7.) Taxable income is 59,234.62

8.) Taxable income is 171,662.58

9.) Taxable income is 184,033.22

10.) Taxable income is 183,997.18

11.) Taxable income is 61,067.11

12.) Taxable income is 153,877.82

13.) Taxable income is 241,356.99

14.) Taxable income is <span>274,376.26
</span>
15.) Taxable income is 97,208.05

Note: Use the "from" amount as the basis, so if the income is 10,000 then you'll deduct 8,925 (basis) from 10,000 (since 10,000 is more than 8,925 but less than 36,250)
