another sequence is 19/480
Part A: Scatter plot with best-fit line attached. You'll find the line to have equation (approximately)

The positive slope suggests that test scores and study time are directly are proportional.
Part B: Same as in a previous question you had posted. Pick two points on the provided line and compute the slope as best you can. For example, I might pick (2, 30) and (4, 40), which gives a slope of

and assuming the line passes through (2, 30) exactly, it would have equation

The value of x is 6
Found using the Angle-Sum-Property of a Triangle
Partitioning the value 26.2
26.2 = 20+6+0.2
The decimal value 0.2 is read two tenth = 2/10
Writing 26.2 as mixed numbers

If we want to write this as an improper fraction, multiply 26 by 10 then add the 2 to get the numerator
Answer: last option.
Step-by-step explanation:
According to the Product of powers property, you have:

As you can see, when you can add the exponents when you have powers with equal base.
Then,
and
do not have the same base, therefore, the exponents can't be added.
Therefore, Eli is incorrect, because he added the exponents even though the bases are not the same.
