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.
A similar problem is given at brainly.com/question/24787716
= 16 + 49 - 3(11) - 4(10)
= 16 + 49 - 33 - 40
= -8
For this case we propose a rule of three according to the data of the statement. To do this, we convert the mixed number into an improper fraction:
cups
4 ----------> 
10 ----------> x
Where the variable "x" represents the amount of chopped of vegetables needed for 10 people.

This is equivalent to
cups.
Answer:
cups
Answer:
OPTION B
Step-by-step explanation:
<h2>
3a - 5</h2>
3 and 'a' are multiplied and 5 is subtracted from the result.
OPTION B says 5 less than 3 times a number would fit perfectly.
Other options talk about adding or taking ratios and clearly do not fit the case.
Hence, the right answer is Option B.
Answer:
102 un²
Step-by-step explanation:
Area surface = 4( 3 x 7 ) + 2( 3 x 3 )
4( 21 )+ 2( 9 ) =
84 + 18 = 102 un²
