Answer:
4) 11.75 6) 23 10) 14
Step-by-step explanation:
4) To find the mean, you would find the average of all the data. To do that, you add all the numbers together, then divide them by the number of numbers there are. So: (14+14+10+12+11+13+11+11+14+10+13+8)/12=141/12=11.75
6) To find the median, you would find the number in between all the numbers. So: 16,20,22,22,22,24,26,26,28,28,28. The median of all of this would be between 22 and 24, so it would be 23.
10) Since one week has 7 days, and the cat drank 2 cups per day, you can multiply 7 and 2 to get 14, and that would be your answer.

Answer:
Green is with C, Blue is with A, Orange is with D, Purple is with B
Step-by-step explanation:
Hi!
So, it's been a while since I've done math like this, so the way I solved this was simply by doing the equations themselves and seeing which one matches. I'm sure there is an algebraic way to find which ones match, but this is all I know how to do :)
(By the way...I got the decimals by doing the fraction itself. 1 divided by 4(1/4th)=.25, as an example)
1(left)-7/1/4 is the same as 7/ .25. This is 28.
2(left) 2/3/ 4/5 is the same as .6666666/ .8. This is .83333repeating
3(left) 4/5 / 3/2 is the same as .8/1.5. This is .53333repeating
4(left) 1/4 / 1/7 is the same as .25/.143. This is 1.74(approx.)
1(right) 2/3 x 5/4 is the same as .66666 x 1.25 This is .8333 approx.
2(right) 1/4 x 7 is the same as .25*7. This is 1.75
3(right) 7*4 is 28.
4(right) 4/5 x 2/3 is the same as .8x.66666. This is .533
Now, we can match.
Green is with C.
Blue is with A
Orange is with D
Purple is with B

(PLEASE HELPP) The number of 6th graders in RSM summer camp to that of 7th graders was 4 to 11, while the number of 5th graders to that of the 6th graders was 13 to 9. By what percent did the number of 7th graders exceed that of the number of 5th and 6th graders taken together ?
Answer:
The number of 7th graders exceed that of the number of 5th and 6th graders taken together by 5.88%.
Step-by-step explanation:
I am going to say that:
x is the proportion of 5th graders.
y is the proportion of 6th graders.
z is the proportion of 7th graders.
The number of 6th graders in RSM summer camp to that of 7th graders was 4 to 11
This means that:
\frac{y}{z} = \frac{4}{11}
z
y
=
11
4
So
11y = 4z11y=4z
y = \frac{4z}{11}y=
11
4z
The number of 5th graders to that of the 6th graders was 13 to 9.
This means that:
\frac{x}{y} = \frac{13}{9}
y
x
=
9
13
9x = 13y9x=13y
x = \frac{13y}{9}x=
9
13y
All of them is 100%
This means that:
x + y + z = 1x+y+z=1
We need to find z.
y = \frac{4z}{11}y=
11
4z
x = \frac{13y}{9} = \frac{13*4z}{9*11} = \frac{52z}{99}x=
9
13y
=
9∗11
13∗4z
=
99
52z
Then
x + y + z = 1x+y+z=1
\frac{52z}{99} + \frac{4z}{11} + z = 1
99
52z
+
11
4z
+z=1
The lcm(least common multiple) between 11 and 99 is 99. Then
\frac{52z + 9*4z + 99z}{99} = 1
99
52z+9∗4z+99z
=1
187z = 99187z=99
z = \frac{99}{187}z=
187
99
z = 0.5294z=0.5294
By what percent did the number of 7th graders exceed that of the number of 5th and 6th graders taken together ?
z(7th graders) is 52.94%.
x + y(5th and 6th graders) is 100 - 52.94 = 47.06%
52.94 - 47.06 = 5.88
The number of 7th graders exceed that of the number of 5th and 6th graders taken together by 5.88%.

Meg is a veterinarian. She found that 5 or, 50% of the dogs she saw this week were boxers. Steve is also a veterinarian. He found that 50% out of the 2 dogs he saw this week were boxers. Does each person need to find the part, the whole, or the percent?
Question content area bottom
Part 1
Meg needs to find the
▼
percent.
part.
whole.
Part 2
Steve needs to find the
▼
percent.
part.
whole.
Answer:
a. Meg needs to find the part
b. Steve needs to find the percent.
Step-by-step explanation:
A. Does Meg need to find the part, the whole, or the percent.
Meg already knows the whole and the percent.
The whole is the entire number of dogs seen: 16 dogs.
The percent is 50%.
Hence, she needs to find the part: this is how many (what part) of the 16 dogs she saw were boxers.
And she can do with a simple operation:
Part = whole × percent = 16 × 50% = 8. This is 8 dogs of 16 were boxers.
B. Does Steve need to find the part, the whole, or the percent.
He already knows the part (7 of the 35 dogs were boxers) and the whole (35 dogs).
Then he needs to find the percent, which he can do using the next operation:
Percent = (part / whole) × 100 = (7/35)×100 = 20%
Step-by-step explanation:
Part 1:
Meg needs to find the whole as 50% of the dogs = 5 therefore 100% equals 10 dogs.
Part 2:
Steve saw 50% out of two dogs meaning that he only saw 1 dog that is a boxer.

You make 12 equal payments for a go-kart. You pay a total of $1380. How much is each payment? The quotient is ______. So, each payment is ___________.
answer plz
Answer:
115; 115

In this case, 1380 is the dividend, 12 is the divider, and the answer is the quotient. Thus we get the quotient, or each payment, is 1380/12=115
A holiday meal cost $12.50 a person plus a delivery fee of 30$. Which equation is right?
1. y=30+12.50x
2. y= 12.50+30
3. 12.50x=30
4. y=12.50+30x
Answer:
1. y = 12.50x + 30
Step-by-step explanation:
A holiday meal cost $12.50 a person plus a delivery fee of 30$
Let x = number of people ordering a meal and y = total cost
It cost 12.50 per person so the cost regarding the number of people that orders food can be represented by 12.50x.
There is also a $30 delivery fee.
So the total cost would (y) = 12.50x + 30
The answer would be 1. 12.50 and 30 just swapped places.

What is the value of m?
13.78 – m = 9.13
Answer:
4.65
Step-by-step explanation:
13.78 - m = 9.13
13.78 - 9.13 - m = 0 (subtracting 9.13 from both sides)
m = 13.78 - 9.13 (adding m to both sides)
m = 4.65
Answer:
m=22.91
Step-by-step explanation:
13.78+9.13=22.91
