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.

(a) Find the linear equation that relates the temperature t and the number of chirps per minute n.
If the equation is linear, then the equation should have the form of t = mn + b
m = (80 - 70) / (168 - 120) = 5/24
t = 5/24n + b
70 = 5/24(120) + b
b = 45
t = 5/24 n + 45
<span>(b) If the crickets are chirping at 138 chirps per minute, estimate the temperature. (Round your answer to the nearest degree.)
</span><span>t = 5/24 n + 45
</span><span>t = 5/24 (138) + 45 = 74 </span>°F
Hello there,
If she has 10 books and she can arrange it 3 ways on her bookshelf, you just multiply 10 and 3
10 x 3= 30
Susan can arrange 10 books into 3 slots 30 ways.
Hope this helps!
