Given data:

51,54,64,68,72,74,76,83,94,94,99

Find:

$P_{75}=?P_{75}= (\frac{75(n+1)}{100})^{th} \ \ observation\\\\$

$= (\frac{75(11+1)}{100})^{th} \ \ observation\\\\= (\frac{75(12)}{100})^{th} \ \ observation\\\\= (\frac{75 \times 12}{100})^{th} \ \ observation\\\\= (\frac{900}{100})^{th} \ \ observation\\\\= 9^{th} \ \ observation\\\\= 9^{th} \ number \ is = 94$

Jim and Martha are standing together at the corner of a rectangular field. Jim walks diagonally across the field. Martha gets to

IgorC [24]

Answer:

Matha - Jim = 200 feet.

Step-by-step explanation:

Jim's distance

J = sqrt(w^2 + L^2)

w = 300
L = 400

J = sqrt(300^2 + 400^2)

J = sqrt(900 + 1600)

J = sqrt(2500)

J = 500

Martha's distance

M = 300 + 400

M = 700 Feet

Answer

M - J = 700 - 500 = 200

Jim walks 200 feet less than Martha.

I need help on this and please explain why is that the answer thank you -Alexa :)

Rzqust [24]

First, you need to find the total amount they discounted.

3.66 X 3= $10.97

Since they took off that much, you need to add that to the total cost, which was 62. 31

62.31 + 10.97= $73.29

Finally, to find how much each individual shirt cost, you divided it by 3.

73.29 / 3= $24. 43

The answer is C
