Answer:

The answer is 88%

Step-by-step explanation:

To find a percentage, just divide the top number by the bottom. 22 divided by 25 is 0.88 which means 22 out of 25 is 88%.

Another way to do it is to multiply both 22 and 25 by 4. The denominator will now equal 100 so now the top number will be the percentage. 22*4 is also 88.

Find the mean.

Answers

Answer:

Mean = 7

Step-by-step explanation:

Given the following data;

Number of games = 8

Scores = 5, 11, 9, 9, 4, 5, 6, 7

We would sum all the scores together to get a total score.

Total scores = 5 + 11 + 9 + 9 + 4 + 5 + 6 + 7 = 56

Now, to find the mean;

$Mean = \frac {total \; scores}{number \; of \; games}$

Mean = 56/8

Mean = 7

Answer:

7 is the mean score.

Step-by-step explanation:

Now we have to,

→ find the required mean score.

The given scores are,

→ 5, 11, 9, 9, 4, 5, 6, 7

→ Numbers = 8

Then the mean score will be,

→ (5 + 11 + 9 + 9 + 4 + 5 + 6 + 7)/8

→ 56/8 = 7

Hence, the mean score is 7.

You are going to college in the fall. You have just heard from your roommate and he asks you to bring the stereo system for the dorm room. You find the perfect system for $1750. You have to put 25% down and you can pay the balance in 18 equal installments. The clerk tells you that you will pay a total finance charge of $112. How much is the down payment and what is the total amount financed including the finance charge? a. $437.50; $1424.50 b. $437.50; $1312.50 c. $43.75; $1818.25 d. $43.75; $1706.25

Answers

Answer:

Option a. is the correct answer.

Step-by-step explanation:

The cost of stereo system = $1,750.00

You have to put down payment = 25% of 1750

= 0.25 × 1750 = $437.50

therefore the balance amount for installments = 1,750 - 437.50 = $1,312.50

Now clerk tells you that you will pay a total finance charge = $112.00

so it would be added to balance amount

= 1,312.50 + 112.00 = $1,424.50

So the down payment would be $437.50 and total amount financed incuding the finance charge would be $1,424.50.
