A researcher observes the level of aggression of six 5-year-old boys over the course of a school day. The number of incidents for the group of boys was 2, 4, 6, 12, 8, 10. What is the mean number of aggressive acts for this group of children

Answers

Answer 1

Answer:

7

Step-by-step explanation:

Mean number = Sum of all the numbers/ Total number of old boys

Given the data

2, 4, 6, 12, 8, 10

Sum = 2+4+6+12+8+10

Sum = 42

Total number of old boys = 6

Substitute into the formula

Mean number of aggressive acts = 42/6

Mean number of aggressive acts = 7

Hence the mean number of aggressive acts for this group of children is 7

Alice used a $250 cash advance from her credit card company to get cash while on a trip. The company charges a daily finance fee of 0.047%. She reported the advance plus the finance fee 40 days later. What amount did Alicia repay the company?

Answers

you do 0.047×40 and what ever that gives you you add it to 40 and it will give you the answer

The amount Alicia repaid to the company after 40 days is $254.7.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Advance cash = $250

Daily finance fee = 0.047%

The daily finance fee for 40 days.

= 40 x (0.047% x 250)

= 40 x 0.1175

= $4.7

The total amount paid after 40 days.

= 250 + 4.7

= $254.7

Thus,

The amount paid to the company is $254.7.

What Multiple Of 7 is less than 45 but greater than 40? A.41 B. 42 C.43 D.44

Answers

Answer:

The correct answer is B, 42.

Step-by-step explanation:

In order to know the answer to the given question, the following logical reasoning has to be made:

The multiple number of 7 that is less than 45 but greater than 40 is 42. This is so since 42 is the result of multiplying 7 by 6 (7 x 6 = 42). In turn, 7 multiplied by 5 is equal to 35 (7 x 5 = 35), which does not exceed the number 40, while 7 multiplied by 7 is equal to 49, which is not less than 45 (7 x 7 = 49).

Cory and Everett have collected model cars since the third grade. Cory has 80 model cars in his collection, which is 25% more than Everette has. How many model cars does Everette have?

Answers

Answer:

64 model cars.

Step-by-step explanation:

What we know.

Cory has 80 cars in his collection.

That is 25% more than Everett has.

We can deduce that the equation would be c = 1.25e.

So, how do we figure out e?

Well, 1.25 is the same as 5/4.

So, find the reciprocal of 5/4 and multiply by 80.

4/5 * 80 = e

64 = e

Everett has 64 model cars in his collection
