You have 20 quarters and then find 40% more and then spend 75% how much money do you have left

kirza4 [7]

You have $1.75 left

Step-by-step explanation:

Given,

Number of quarters already have = 20

Percent of quarters found = 40% of already have

Number of quarters found = $\frac{40}{100}*20$

Number of quarters found = $\frac{800}{100}$

Number of quarters found = 8

New total = 20+8 = 28 quarters

Percent of quarters spent = 75%

Number of quarters spent = $\frac{75}{100}*28$

Number of quarters spent = $\frac{2100}{100}$

Number of quarters spent = 21

Quarters left = 28-21 = 7

1 quarter = 25 cents

7 quarters = 25*7 = 175 cents

$1 = 100 cents

175 cents = $\frac{175}{100}=\$1.75$

You have $1.75 left

zheka24 [161]

Answer:

Step-by-step explanation:

Let X be the random variable for the time needed to grade a randomly chosen first examination paper

X is N(5, 4)

Time taken=11.00-6.50=4hours 10 min=25/6 hours

P(X<25/6) =P(Z< $\frac{\frac{25}{6}-5 }{4} =P(Z$

=0.5-0.0832=0.0168

b) Time >11.10-6.50 = 4 hours 20 mint = 13/3 hours

P(X>13/3) = P(Z>-0.16) = 0.5636
