In a random sample of 200 college students, 110 were females,125 were under the age of 21 years of age, and 45 males were 21 yea

Liono4ka [1.6K]

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

Total number of students = 200

Number of females = 110

Number of students under the age of 21 years of age = 125

Number of males under the age of 21 years or older = 45

So, it becomes

Males Females Total

21 years 45 80 125

21 years or older 45 30 75

Total 90 110 200

So, Probability that a female student age 21 or older is selected is given by

$\dfrac{30}{200}=0.15=15\%$

Hence, Option 'a' is correct.

In one day, the stock price for Zell Computers rose from $50 to $57 per share. By what percent did this stock price rise?

netineya [11]

The stock price rose by 14%

Percentage is the fraction of a sum expressed as a number out of hundred.

Percentage price increase = (change in price / initial price) x 100

In order to determine the answer, the following information is needed :

Change in stock price:

New price - Initial price

$57 - $50 = $7

Initial price = $50

Percentage increase in stock price : ($7 / $50) x 100 = 14%

In order to determine the percentage increase in the stock price, express the increase in price as a fraction of the initial price and multiply by 100

Yvonne's car with an 11-gallon gas tank gets an average of 32 miles per gallon. She travels 12 hours at an average speed of 64 m

n200080 [17]

Answer:

$78

Step-by-step explanation:

Here we have to find total distance first then find amount of gasoline used based on distance traveled by car in one gallon.

_____________________________________________

Given

time = 12 hours

speed = 64 miles per hour

we know distance = speed * time

distance = 12*64 = 768 miles.

Thus, car ran 768 miles.

given that car gets an average of 32 miles per gallon.

It means in one gallon gasoline car travels 32 miles.

let the gallons used be x

in 1 gallon gasoline car travels 32 miles.

in 1*x gallon gasoline car travels 32*x miles = 32x

Thus, 32x should be equal to 768 miles as car traveled that much only

32x = 768 miles

x = 768/32 = 24

Thus, gallons of gasoline used is 24.

Cost of 1 gallon gasoline = $3.25

since, gallons found is 24, we multiply lHS and RHS by 24

Cost of 1 *24= 24 gallon gasoline = $3.25*24 = $78

Thus,

cost of 24 gallon is $78 which will be the gasoline cost for the trip.
