Answer 1
Answer:
Answer:

the mean of the entire class is approximately 64.74.

Step-by-step explanation:
To find the mean of the entire class, we'll calculate the overall average by considering the total number of students and their average scores.

Total number of students = 25 (females) + 70 (males) = 95 students

Total score of females = 25 (females) * 50 (average score) = 1250

Total score of males = 70 (males) * 70 (average score) = 4900

Total score of the entire class = 1250 (females' total score) + 4900 (males' total score) = 6150

Mean of the entire class = Total score of the entire class / Total number of students = 6150 / 95 ≈ 64.74

So, the mean of the entire class is approximately 64.74.

Bodhi has a collection of 175 dimes and nickels. The collection is worth $13.30. Which equation can be used to find n, the number of nickels in the collection?

Answers

Let

n-------> the number of nickels

d-------> the number of dimes

we know that

1\ nickel=\$0.05

1\ dime=\$0.10

so

0.05n+0.10d=13.30 -----> equation A

n+d=175

d=175-n -------> equation B

substitute equation B in equation A

0.05n+0.10(175-n)=13.30 ------> equation that can be used to find n

Solve for n

0.05n+17.5-0.10n=13.30

17.5-13.30=0.10n-0.05n

0.05n=4.2

n=84\ nickel

find the value of d

d=175-n

d=175-84=91\ dimes

therefore

the answer is

The equation that can be used to find n is 0.05n+0.10(175-n)=13.30

The number of nickels in the collection is 84\ nickel

n + d = 175 .... d = 175 - n
0.05n + 0.10d = 13.30

0.05n + 0.10(175 - n) = 13.30 <== and u would just solve for n
