Given that Joseph earns $15 for every lawn he mows.
so if he mows lown 1 time then his earning = $15
if he mows lown 2 time then his earning = $15*2= $30
if he mows lown 3 time then his earning = $15*3= $45
if he mows lown 4 time then his earning = $15*4= $60
if he mows lown 5 time then his earning = $15*5= $75
So the required table will be:
From the table we can see that Joseph's earning increases by $15 each time so we can say that YES, the amount of money he earns proportional to the number of lawns he mows.
Answer:
21/25 = 84/100
17/20 = 85/100
21/25 < 17/20
Step-by-step explanation:
∵ The common multiple of 25 and 20 is 100
∵ 100 ÷ 25 = 4
∴ 21/25 = (21 × 4)/(25 × 4) = 84/100
∵ 100 ÷ 20 = 5
∴ 17/20 = (17 × 5)/(20 × 5) = 85/100
∵ 84 < 85
∴ 84/100 < 85/100
∴ 21/25 < 17/20

A) Variance = 10.24
B) Standard Deviation = 3.2
One of the measurements of dispersion is the standard deviation, which is exclusively used for quantitative data. It aids in determining if the data's mean is a suitable measurement to reflect the core value.

Standard Deviation = 
√4.35 - √1.15
Standard Deviation = 3.2
(SD)² = (3.2)² = 10.24
Variance = 10.24
