I think your image for your regression line didn't show up, but judging from what I see, the answer should be:
<span>D) In step 4, Tameka mistakenly based the strength of the association on the slopes.
This is because the strength of the association is not determined by the slope of the regression line, but by how close the data points were to the actual line. The closer the points are to the actual regression line, the stronger the association.

First, let's write down this inequality:
<span>There are at least 245 students enrolled in the school.
y≥245
This inequality says what the sentence says!
now, the number of teachers must be:
x≥2*(y/25)
(two times the number of groups of students of 25!)
so those two inequalities, taken together will be the answer!

Answer:
The total money invested in the field will be 
Step-by-step explanation:
step 1
Find the dimensions of the field
Let
x -----> the length of the field
y -----> the width of the field
we know that
The perimeter of the field is equal to
so
----> equation A
------> equation B
substitute equation B in equation A and solve for y
Find the value of x
therefore
The length of the field is 130 meters and the width of the field is 35 meters
step 2
Find the area of the field
The area of the field is
substitute
step 3
Find the number of bags of seed
Divide the area by 460
Round up to the nearest whole number
step 4
Find the cost of the seed
step 5
Find the total money invested in the field
The number of integers from 100 to 900 that can be written in base ten without using the digit 7 is 648.
From 100 to 999, all integers are three (3) digit numbers and available digits are (0, 1, 2, 3, 4, 5, 6, 7, 8, 9).
It implies that the total number of digits is 9. The next thing to do will be to arrange the 9 digits in three (3) places in such a way that repetition is allowed.
In the first place;
- the number of ways the number can be positioned since it can't be zero and seven = 8.
Hence, the first chance is 8 out of 10 chance.
In the second and third place;
∴
The number of integers from 100 to 900 that can be written in base ten without using the digit 7 is:
= 8 × 9 × 9
= 648
Therefore, the number of integers from 100 to 900 that can be written in base ten without using the digit 7 is 648.
