(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.

The cost of having photos taken includes a sitting fee and $12 for each portrait. The cost of 3, 6, and 9 photos respectively is $51, $87, and $123. What is the sitting fee? Use units in your answer and round answer to the hundredths place, for example $2.35
plz help
Answers
Answer:
The sitting fee is 15 dollars
Step-by-step explanation:
1 - 12 x 3 = 36
2 - 51 - 36 = 15
3 - 12 x 6 = 72
4 - 87 - 72 = 15
Answer:
$15.00
Step-by-step explanation:
cost of photos = sitting fee + $12 per photo
Let the number of photos = x
Let the sitting fee = s
cost of photos = s + 12x
cost of 3 photos = $51
s + 12(3) = 51
s + 36 = 51
s = 15
Answer: The sitting fee is $15.00

a) 20.9
The mean is calculated by adding up the scores and dividing the total by the number of scores, it is also called the average.
First, we can count and see there are 11 players (makes sense for a football team). Adding up the ages gives us 19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 = 230. Divide by 11 and we get a mean of of about 20.9!
b) 30
To figure this out, we will set up an equation that looks like this:
[tex]\frac{19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23+x}{12} =22[/tex]
And now we will solve:
[multiply both sides by 12] 230 + x = 264
[subtract 130 from both sides] x = 30
So the age of the new player should be 30!
Have a nice day!

Melinda saves 2 less dollars than Marcus each week.
Step-by-step explanation:
Y = 12x + 75 is Melinda's equation. Y = 14x + 25 is Marcus's equation. First we'll disregard how much money they have saved already to see how much they save weekly. So Melinda's new equation is Y = 12x, and Marcus's new equation is Y = 14x. Now we'll do Marcus's equation (14x) - Melinda's equation (12x) to see how much more money Marcus saves each week, which will in turn will tell us how much less money Melinda saves each week.
14 x - 12x = 2. (x-x=0) This tells us Marcus saves 2 more dollars than Melinda each week.
Which gives us our answer, Melinda saves 2 less dollars than Marcus each week.

Step-by-step explanation:
You are given the equation y=5-4x. You can put that into slope intercept form. Slope intercept form is y=mx+b where b is the y intercept and m is the slope. In this equation the slope is -4 and the y intercept is 5. You can rearrange this equation into slope intercept form. If you do this you will get y=-4x+5.
