If you score 76, 85, 97 and 82 on your math tests, what would your average mean score be? *
1 point
A) 82
B) 90
C) 85
D) 88

Answers

Answer 1

Answer:

（76＋85＋97＋82）/4

Step-by-step explanation:

Four subjects total divided by 4 to get the mean

Answer 2

The average mean score is 85

The correct answer is option (C)

What is average?

"It is the sum of all the values divided by the total number of values."

What is mean?

"It is the average of the given values."

For given example,

the score in the math tests are 76, 85, 97 and 82

total score = 76 + 85 + 97 + 82

total score = 340

The number of math tests are 4.

So, the average score would be,

average = [tex]\frac{340}{4}[/tex]

average = 85

Therefore, the average mean score is 85

The correct answer is option (C)

5) CORRIDOR
6) NUMBER

Answers

Answer:

Ur Answer is 5 one CORRIDOR

The number of unique permutations of the letters CORRIDOR is 3360

The number of unique permutations of the letters NUMBER is 720

What is Permutation?

A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters. Common mathematical problems involve choosing only several items from a set of items in a certain order.

[tex]\frac{n!}{mA!mB!......mZ!}[/tex]

In the given word

CORRIDOR

There are 7 letters in which "O" repeats 2 times and "R" repeats 3 times.

Then n = 7 , A = 2 and B = 3

Put values in above formula

Then,

=  [tex]\frac{7!}{2!3!}[/tex]

= [tex]\frac{7\times6\times5\times4\times3\times2\times1}{2\times3\times2}[/tex]

= 3360

Similarly

NUMBER

There are 6 letters in which no letter repeats

means A = B = .......= Z = 1

Put values in above equation

= [tex]6![/tex]

= 720

Hence,

The number of unique permutations of the letters CORRIDOR is 3360.

The number of unique permutations of the letters NUMBER is 720.

A rental car company charges $53.75 per day to rent a car and $0.12 for every mile driven. Jaya wants to rent a car, knowing that: She plans to drive 125 miles. She has at most $230 to spend. Write and solve an inequality which can be used to determine xx, the number of days Jaya can afford to rent while staying within her budget.

Answers

Answer:

Jaya can afford to rent a car 4 days while staying within her budget.

Step-by-step explanation:

The inequality would have to indicate that the cost of renting a car has to be less than or equal to $230. The cost to rent a car is equal to the cost per day for the number of days plus the price per mile for the number of miles, which is:

53.75x+0.12y≤230, where:

x is the number of days the car is rented

y is the number of miles driven

As the statement says that she plans to drive 125 miles, you can replace "y" with this value and solve for x:

53.75x+0.12(125)≤230

53.75x+15≤230

53.75x≤230-15

53.75x≤215

x≤215/53.75

x≤4

According to this, the answer is that Jaya can afford to rent a car 4 days while staying within her budget.
