Considering that the data has no outliers, the mean of 3.2 inches should be used to describe the center of the data represented in this line plot.
<h3>What measure should be used to describe the center of a data-set?</h3>
It depends if the data-set has outliers or not.
- If it does not have outliers, the mean should be used.
- If it has, the median should be used.
The dot plot gives the number of times each measure appears. Since there is no outliers, that is, all values are close, the mean should be used. It is given by:
M = (2 x 1 + 3 x 2 + 2 x 3 + 1 x 5 + 1 x 6 + 1 x 7)/(2 + 3 + 2 + 1 + 1 + 1) = 3.2 inches.
The mean of 3.2 inches should be used to describe the center of the data represented in this line plot.

Answer:
the hourly rates are $8 and $10 respectively
Step-by-step explanation:
Given that
The generator rents for 6 hours and the total cost is $48
And, for another job The generator rents for 4 hours and the total cost is $40
We need to find out the hourly rates
For the first one
= $48 ÷ 6 hours
= $8
For the second one
= $40 ÷ 4 hours
= $10
Hence, the hourly rates are $8 and $10 respectively
An expression for “7 divided by c” is 7/c or 7 ÷ c
1.x+16
2.x-8
3.12/x
these are the algebraic expressions
The probability is C) 3/8.
The spinner landed on H 15 times out of (12+9+15+4) = 40 times. This is a probability of 15/40, which simplifies to 3/8.
