Answer:
The amount of white paint Jen used to paint the walls in her room is:
Step-by-step explanation:
To solve the exercise you only have to pay attention to the statement, in the section that says that 4/5 parts of the total painting is blue, therefore, if 1 is the total painting, you must do a subtraction:
Since the remaining white paint is 1/5 of the total, you have two ways to solve the exercise: multiply the total paint (8.2 pints) by 1/5 or divide the number by 5, as shown below:
- <u>Amount of white paint = 8.2 pints * (1/5) = 1.64 pints.
</u>
- <u>Amount of white paint = 8.2 pints / 5 = 1.64 pints.
</u>
As you can see, the two methods provide a <u>value of 1.64 pints, which corresponds to 1/5 of the total paint and is the amount of white paint used</u>.
Using the mean concept, it is found that the mean difference between the call times and the company's average call time is given by:
<h3>What is the mean?</h3>
- The <em>mean </em>of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem:
- The four observations are the differences between the time of each phone call and the average time.
- They are: {-2.32, -1.55, 4.79, 0.68}
Hence, the mean difference is:
Hence, option C is correct.

Answer:
mean: 6
median: 6
Step-by-step explanation:
mean = sum of terms divided by number of terms
sum of terms = 11 + 2 + 10 + 3 + 9 + 1 + 6 = 42
number of terms = 7
42/7 = 6
mean = 6
median = the value separating the higher half from the lower half
first, you must organize the numbers from lowest to highest
1, 2, 3, 6, 9, 10, 11
from then, you find the number in the center
that number is 6
median = 6
