Answer:

32.13

Step-by-step explanation:

10% of 42=4.2

Mate gets 4.2

42-4.2=37.8

15% of 37.8=5.67

Mom gets 5.67

37.8-5.67=32.13

32.13

Answer:

31 and a half apples

Step-by-step explanation:

10% of 42 is 42 divided by 10 which is 4.2 apples

15% of 4.2 is 6.3

4.2apples+6.3apples is 10.5apples

So then you take away their apples from 42 apples which is 31.5 apples

which is technically 31 and a half apples.

I hope this helped you

A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test

SSSSS [86.1K]

A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test statistic for this test is a "F-statistics."

<h3>What is F-statistics?</h3>

An F statistic is a value obtained after performing an ANOVA test or even a regression analysis to determine whether the means of two populations differ significantly.

Some key features regarding the F-statistics are-

It is comparable to a T statistic from the a T-Test; a T-test would then inform you when a single result is statistically significant, whereas a F test would then tell you if a set of variables is statistically significant.
When determining whether your total results are significant, you must use the F statistic in conjunction with the p value. Why?
A significant result does not imply that all of your variables have been significant.
The statistic is simply comparing the cumulative influence of all the variables.

Explain linear function. Provide a real-world example of linear function, explain the rate of change. Include reference(s) in yo

GuDViN [60]

Answer:

See step-by-Step explanation

Step-by-step explanation:

An linear equation is an equation that shows the relationship of 2 numbers, and when one variable decreases at a constant rate, the other will also decrease by a constant rate. One example is when you drive at a constant rate at 50 miles per hour. The distance is y miles, and the time is x hours. The linear equation is y=50x.

What part of 3 12 is 1/2 ? I need this asap

Aliun [14]

I assume you are asking one of three things, so I will answer all of them.

if you are asking what is 1/2 of 312, then multiply 312 by 1/2. 312 is really just 312/1, so
$312 \times \frac{1}{2} = \frac{312}{1} \times \frac{1}{2}$
we multiply fractions by multiplying straight across
$\frac{312 \times 1}{1 \times 2} = \frac{312}{2} = 156$

if you were asking what part of 3 1/2 is 1/2 then we have to recognize what 3 1/2 is as an improper fraction. to do this, we convert 3 into halves. how many halves of pizza are there in 3 whole pizzas? 6. so we have 6 halves and one half, which is a total of 7 halves.
$\frac{6}{2} + \frac{1}{2} = \frac{7}{2}$
now, we do the same thing as the first problem
$\frac{7}{2} \times \frac{1}{2} = \frac{7 \times 1}{2 \times 2} = \frac{7}{4}$

if you were asking what is half of 3.12, then we convert 1/2 to a decimal and multiply
$\frac{1}{2} = .5 \\ 3.12 \times .5 = 1.56$
