Answer:

6 times larger

Step-by-step explanation:

First, find the area of both.

Mary: 4*5.5=22

Lisa: 24*5.5=132

Then find what multiplied by 22 would equal 132. This is easy because it's a multiple-choice question.

22*20=440, so A is incorrect

We already know they are not equal, so then B can be crossed out

22*3=66, C would be incorrect

Leaving the only choice left to be the correct answer

22*6=132

Answer:

20%

Step-by-step explanation:

100/20 (the number of questions) = 5 (how much each question is worth)

16(the number of questions she got correct) times 5 is 80

She got 80 percent correct

That means that she missed 20 percent

Answer:

y= 18x + 15

Step-by-step explanation:

If its 9 dollars per hour than it would be 18 per hour. The independent variable is the how long itll take, and the 15 would be without starting. So it results into B) y=18x+15

Answer:

D. (Y=9x+15)

Step-by-step explanation:

This one was pretty easy to find out using common sense, it can be solved via knowing that the only variable being multiplied is 9, so find 9x+15 and there is your answer.

Answer:

Both pools will have the same amount of water after 11 minutes and 32 seconds.

Step-by-step explanation:

Since Team Sunshine is filling an inflatable kiddie pool from a garden hose, and the pool has 30 gallons in it and Team Sunshine is adding 8 gallons per minute with a garden hose, while next door, Team Breeze's pool is already filled with 180 gallons of water, and they are emptying the pool at 5 gallons per minute with buckets, to determine how long it will take until both pools have the same amount of water, the following calculation must be performed:

Team Sunshine:

30 + (8X) = T

30 + 8x10 = 110

30 + 8x11 = 118

30 + 8x12 = 126

30 + 8x11.5 = 122

30 + 8x11.6 = 122.8

30 + 8x11.55 = 122.4

30 + 8x11.54 = 122.3

Team Breeze:

180 - (5X) = T

180 - 5x11 = 125

180 - 5x12 = 120

180 - 5x11.5 = 122.5

180 - 5x11.6 = 122

180 - 5x11.55 = 122.25

180 - 5x11.54 = 122.3

1 = 60

0.54 = X

0.54 x 60 = X

32.4

Thus, both pools will have the same amount of water after 11 minutes and 32 seconds.

Answer:

The unit rate would be 38 miles per hour

Step-by-step explanation:

The probability of having 2 girls and 3 boys in a 5-child family is 5/16

Probability is the likeliness of an event to happen .

Total Probability of having 5 kids as boy or girl is 2⁵ = 32

The probability that there is 3 boys in the 5 children and remaining two are girls

[tex]\rm ^5C_3[/tex]

= (5*4*3*2*1)/(2*1)(3.2.1)

= 10 ways

probability of having 2 girls and 3 boys in a 5-child family is

=10/32

= 5/16

Therefore ,  the probability of having 2 girls and 3 boys in a 5-child family is 5/16

Answer: 1/10, 3/20, 1/4, 1/5, 3/10

Step-by-step explanation: So first, you need to find the total number of times Leon spins the spinner, which is 20. You get 20 by counting the total number of x's there are.

Then you need to find the number of times each number got landed on. In order, it would be 2/20, 3/20, 5/20, 4/20, and 6/20.

Next, you have to simplify them. 2/20 simplified is 1/10, then 3/20 can't be simplified, so leave it like that, 5/20 would be 1/4, 4/20 would be 1/5, and finally, 6/20 would be 3/10.

Answer:

3.46

Step-by-step explanation:

Given the regression output :

Predictor Coef ___SE __ Coef __ T ___ P

Constant 2.6476_0.3281_ 8.07 0.000

Sleep 0.10176 0.04347 **** *****

S = 0.1804

R-Sq = 31.3%

R-Sq(adj) = 25.6%

The regression equation which models the relationship between hours of sleep a student gets and his GPA can be obtained from the regression output :

The GPA is the dependent, y variable

Hours of sleep is the independent, x variable

y = 0.10176x + 2.6476

Hence, the GPA of a student who gets 8 hours of sleep on a typical school can be computed thus ;

Hours of sleep, x = 8

y = 0.10176(8) + 2.6476

y = 0.81408 + 2.6476

y = 3.46168

Thus, predicted GPA = 3.46

1.

Yes , the data franchise owner is collecting, will be helpful in order to counter the criticism from the critic. As he has a record for every delivery they are making on daily basis.

2.

The scenario is that for every fifth customer , the owner cross the four lines he makes. Thus a pack of five and easy to remember. As the data on regular week days is less, As can do the same for the third customer. Crossing the 2 lines for 3rd customer.

3.

With this provision of crossing the third customer, the owner can have a better check on the late delivery. As it will bring in his notice earlier as compared to fifth crossing.

4.

With the data as provided in the table, we can come to the conclusion that on weekends , i.e. both on time delivery and late deliveries are high in numbers. It must be because of high demand on that days. So owner must make some provision like hiring some more delivery boys for weekend in order to reduce the late deliveries.

Answer:

m<K, m<J, m<I

Step-by-step explanation:

The size of angles and sides correspond. The larger the side, the larger the angle must be. So, this means the largest angle will be directly across from the longest side. Since <K is across from the smallest side, it is the smallest angle. Additionally, <I is across from the longest side so it is the largest.

Answer:

3/9

Step-by-step explanation:

numerator:7-4=3/9

The subtraction of the the fraction 7/9 -4/6 results to 1/3.

Given Fraction:

7/9 - 4/9

To subtract fractions, have a common denominator.

In this case, both fractions already have the same denominator of 9,

Now, subtract the numerators as:

= 7/9 - 4/9

= (7 - 4)/9

= 3/9

By dividing both the numerator and denominator by 3 gives

3/9 = 1/3

So, the answer to 7/9 - 4/9 as a simplified fraction is 1/3.
