Answer 1
the answer is to the question is A, sorry if I’m late.
Answer 2

Mean is greater for grade 7.

Median is greater for grade 7.

So, the correct options are B and D.

What is mean and median?

"The mean is the number you get by dividing the sum of a set of values by the number of values in the set.

The median is the middle number in a set of values when those values are arranged from smallest to largest."

Mean for grade 6 is

= [tex]\frac{1+2+3+1+1+1+1}{7}[/tex]

= [tex]\frac{10}{7}[/tex]

Mean for grade 7 is

= [tex]\frac{1+2+5+2}{4}[/tex]

= [tex]\frac{10}{4}[/tex]

From both we get, Mean is greater for grade 7

Median for grade 6 is 1

Median for grade 7 is

= [tex]\frac{2+5}{2}[/tex]

= 3.5

From both we get, Median is greater for grade 7

So, the correct options are B and D.

John's salary last year was $80000. Last year he got a raise of 10%. This year
the company lost money and his salary was cut back to S80000 By what percent did
his salary decrease this year?

Answers

Answer:

so I dont think that my answer is right but since his salary was 80000 last year but he got a raise of 10% then he got 8000 more so then he got 88000 in total but then they took away $80000 so I think they took away 90%

It is 10%, since his salary came back to what it was before the raise.

Answers

Answer:

h + c = 3 and 4h + 4c =10

No solutions

Step-by-step explanation:

If hot dogs = h, and chips = c,

Then the first scenerio can be written as h + c = 3

The second scenerio is 4h + 4c = 10.

So, your system should be

h + c = 3 and 4h + 4c =10

Solve this system

First, solve c + h = 3 for c.

Subtract h on both sides.

c = -h + 3

Then, substitute c = -h + 3 into the second equation (4c + 4h = 10)

4(-h + 3) + 4h = 10

Simplify.

- 4h + 12 + 4h = 10

12 = 10

This is not right, so this system has no solutions. This means that there is no set cost for the chips or hot dogs (or for both).

Hope this helps! Feel free to ask any questions

Ruby says that 4/5 divided by 2/15 = 14/15. What error did Ruby make? A. Ruby added instead of divided. B. Ruby divided 2/15 by 4/5 instead of 4/5 by 2/15. C. Ruby divided by 2 instead of dividing by 2/15. D. Ruby multiplied by 2/15 instead of 15/2 multiplying by .

Answers

Answer:

A. Ruby added instead of divided

Step-by-step explanation:

You must find a common denominator (15), and then multiply by the reciprocal and simplify your final answer

12/15 times 15/2 equals 180/30 which, when simplified equals 6

Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.

What is simplification?

Using mathematical operations it is to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Ruby says that 4/5 divided by 2/15 = 14/15, which is incorrect.
4 / 5 divided by 2/15 is 6,
When we add both numbers,
= 2 / 15 + 4 / 5
= [2 + 12] / 15
= 14 / 15

Thus, Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.

Answer:

W = 8.2 cm

Step-by-step explanation:

The perimeter formula is P = 2W + 2L and here the perimeter is 65.6 cm.

Thus, 65.6 cm = 2W + 2L.  Substituting 3W for L, we get

          65.6 cm = 2W + 2(3W) = 8W.

Solving for W by dividing both sides by 8, we get W = 65.6 cm / 8, or

W = 8.2 cm

W=8.2 cm. Trust me I have my sources.
