Answer:
C. 18.75
Step-by-step explanation:
3 + 5 + 3 + 6 = 17
30 + 30 = 1
17 + 1 = 18
45 in decimal form is .75
the answer is 18.75
1, 2, 3, 6, 7, 14, 21, 43
6th one is 14
After 7 weeks the plant will 11.25 units tall if the equation for the best-fit line to be y = 2.5 + 1.25x.
<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:
y = 2.5 + 1.25x
Plug x = 7 weeks
y = 2.5 + 1.25(7)
y = 11.25 units
Thus, after 7 weeks the plant will 11.25 units tall if the equation for the best-fit line to be y = 2.5 + 1.25x.

Answer:
13 units
Step-by-step explanation:
Use the distance formula, d =
, where (x2, y2) and (x1, y1) are two different points on the line.
Plug in the values:
d = 
d = 
d = 
d = 
d = 
d = 13
Answer:
71.9
Step-by-step explanation:
Whenever you want to round a number to a particular digit, look only at the digit immediately to its right. For example, if you want to round to the nearest tenth, look to the right of the tenths place: This would be the hundredths place digit. Then, if it is 5 or higher, you get to add one to the tenths digit.
