4 babysitters earn $6 or more per hour because 3 earn $6 and 1 earn $7. The others all earn $5 or less per hour.
Using the given linear function, the formula underestimates the median weekly earnings in 2013 by $3.
<h3>What is the linear function for the estimate?</h3>
The function that estimates the median weekly earnings n years after 1980 is given by:
W = 13n + 231.
2013 is 2013-1980 = 33 years after 2000, hence the estimate is given by:
W = 13 x 33 + 231 = 660.
Since 657 < 660, the formula underestimates the median weekly earnings in 2013 by $3.

Answer:
C.) y/2
Step-by-step explanation:
We can simplify (x+3)/3 to x/3 + 3/3, then simplify (y+2)/2 to y + 2/2, and since 2/2 and 3/3 are both 1, so we can say that x/3 + 1 = y/2 + 1, meaning that x/3 = y/2.
Answer:
No.
Step-by-step explanation:
This is incorrect because the hot air balloon traveled up to 7500 feet. The distance descended cannot be greater than 7500 feet. Joe's expression tells us that the hot air ballon descended 10500 feet. He is incorrect because 10500 > 7500.
