Answer:
Step-by-step explanation:
-3w + 7 = -14
subtract 7 from both sides
-3w + 7 - 7 = - 14 -7
-3w = -21
divide both sides by (-3)
-3w/-3 = -21/-3
w = 7
In short:
-3w + 7 = -14
-3w = -14 - 7
-3w = -21
w = -21/-3
w = 7
Divide both fractions to make them a decimal or whole number subtract 3.3 - 2.6
3.3 is 33/10
2.6 is 13/5
You will get 0.7 which is 7/10 of the leftover rope

A mean is an arithmetic average of a set of observations. The mean number of visits the students made to the library in the last month is 2.32 visits.
<h3>What is Mean?</h3>
A mean is an arithmetic average of a set of observations. it is given by the formula,
Mean = (Sum of observations)/Number of observations
For the given frequency table, the sum of the mean and the total number of values can be written as,
Sum = (0×284) + (1×218) + (2×76) + (3×64) + (4×42) + (5×320) = 2330
Total number of values = 284 + 218 + 76 + 64 + 42 + 320 = 1004
The mean for the table can be written as,
Mean = sum/ Total number of values = 2330/1004 = 2.32
Hence, the mean number of visits the students made to the library in the last month is 2.32 visits.
