The meaning of the constant is the average temperature at the equator statement (A) is correct.
<h3>What is the line of best fit?</h3>
A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
We have a line of best fit for the data:
y = 90 - z
Here, x is measured in degrees of latitude and y is measured in degrees of Fahrenheit.
When z = 0
y = 90
Which shows the average temperature at the equator.
Thus, the meaning of the constant is the average temperature at the equator statement (A) is correct.

He is buying one large tree, so subtract the cost of a large tree from the total:
1400 - 200 = 1200
He can spend 1200 on small trees.
Divide 1200 by the cost of a small tree to find how many small trees can be bought:
1200 / 150 = 8
He can buy 8 small trees.
Total number of trees = 8 small + 1 large = 9 total
Answer: $835.88
Step-by-step explanation:
SP after 7% sales tax = 543.32
SP = MP (100 - d) / 100
543.32 = MP (100 - 35) / 100
543.32 = 0.65MP
MP = 835.88
