Using the mean concept, it is found that:
Relative to Sabrina's goal, her average swim time over the last five weeks is 0.1 hours.
-----------------------
The mean of a data-set is given by the <u>sum of all observations divided by the number of observations</u>.
In this problem:
- The data-set is her swim time relative to her goal, which is: {1.25, -1, 2.25, 0, -2.}
Thus, the mean is:

Relative to Sabrina's goal, her average swim time over the last five weeks is 0.1 hours.

The measure of G is 28 because it is an isosceles triangle
Answer:
Step-by-step explanation:
<1 + <2 = 180 degrees (straight angle)
<3 + <5 + <4 = 180 degrees (straight angle)
<1 = <3 (vertical angles)
<1+<2 = <3+<4+<5 (straight angles)
<2 = (<3-<1)+<4+<5 (<3 - <1 = 0)
<2 = <4 + <5
Answer:
2,400=22%
9300=25%
12000=28%
6300=25%
Step-by-step explanation:
We will find the rate of Greg and Josh earning money that is
the amount of money they receive per unit time (hour)
Since the trip is in 3 weeks,
Number of hours Josh worked = 3 weeks * (5 hours/week) = 15
hours
Number of hours Greg worked = 3 weeks * (8 hours/week) = 24
hours
Josh’s rate = $480/15 hrs = $32/hr
Greg’s rate = $480/24 hrs = $20/hr
Therefore
Josh makes $12/hr more than Greg
