Step-by-step explanation:
The true statement is both the mean and median are greater for Plot A than for Plot B..
<h3>What is the true statement?</h3>
Mean is the average of a data set. Median is the number at the center of a dataset arranged in either ascending or descending order.
Mean for plot A = (3 + 4 + 4 + 5 + 5 + 6 + 6 + 7 + 7 + 10) / 10 = 5.7
Median for plot A = (5 + 6) / 2 = 5.5
Mean for plot B = (3 + 4 + 4 + 5 + 5 + 5 + 6 + 6 + 6 + 7) / 10 = 5.1
Median for plot B = 5

Answer:
x=-1/4+i*sqrt(47)/4 and x=x=-1/4-i*sqrt(47)/4
Step-by-step explanation:
Using quadratic formula, x=(-1±sqrt(1-48))/4.
x=-1/4+i*sqrt(47)/4 and x=x=-1/4-i*sqrt(47)/4
19 hours
Calculate his hourly rate by dividing $91 by 13
hourly rate =
= $7
Now divide $133 by 7 to find number of hours he has to work
= 19 hours
