Nine cyclists were each asked the distance in miles they biked last week.
Their responses are given below.
Complete the grouped frequency distribution for the data.
In the distribution, the frequency of a class is the number of distances in that class.
(Note that we are using a class width of 6.)

Answers

The frequency for 2 to 7 is 3

The frequency for 8 to 13 is 4

The frequency for 14 to 19 is 2

The grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.

Given that, nine cyclists were each asked the distance in miles they biked last week. The distance travelled by 9 cyclists is 16, 8, 2, 6, 8, 11, 9, 15 and 7.

We need to complete the grouped frequency distribution for the data.

What is the grouped frequency distribution?

In this type, the data is arranged and separated into groups called class intervals. The frequency of data belonging to each class interval is noted in a frequency distribution table. The grouped frequency table shows the distribution of frequencies in class intervals.

Now, the frequency distribution for the given intervals is as follows:

That is, for intervals 2 to 7 the frequency is 3.

For intervals 8 to 13 the frequency is 4.

For intervals 14 to 19 the frequency is 2.

Therefore, the grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.

Jazmyn uses 2 gallons of paint to paint 5 walls. He uses 4 gallons of paint to paint 10 walls. How many gallons of paint does he use per wall?

Answers

Answer:

2/5 gallons

Step-by-step explanation:

If it takes 2 gallons of paint to paint 5 walls, then the amount of gallons used per wall can be calculated by comparison

[tex]5 walls = 2 gallons \\ 1 \: wall = x \: gallons \\ by \: cross \: multiplication \\ 5 \times x = 2 \times 1 \\ 5x = 2 \\ x = \frac{2}{5} [/tex]

Hence, 2/5 gallons of paint is used per wall.

An account with an initial balance of $4000 earns 6.5% interest for 5 years.
What is the ending balance?
Enter your answer in the box. $.

Answers

Answer:

The balance in the bank after 5 years of 6.5% interest is $5,300.

Step-by-step explanation:

*Presuming that this is not a compounding interest the interest would just multiply by the even balance.*

So every 5 years the balance earns 0.065 of 4,000 dollars.

This would make our equation:

4000 + (4000  x .065 x 5 )

= 4000 + (1300)

= 5300

The balance in the bank after 5 years of 6.5% interest is $5,300.

5,300
