Y - 3x = -8
y = 3x - 8...slope here is 3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -1/3.
y = mx + b
slope(m) = -1/3
(3,2)...x = 3 and y = 2
now we sub and find b, the y int
2 = -1/3(3) + b
2 = -1 + b
2 + 1 = b
3 = b
so ur perpendicular equation is : y = -1/3x + 3
The population would be set of all Christians of that particular church from where the random samples is collected.
According to the questions,
A study was performed with a random sample 3000 people from one church. In order to find appropriate population for generalizing conclusions
The population would be set of all Christians of that particular church from where the random samples is collected.
- This is because random samples is collected only from the particular church, so its generalization can only be the possible to large population of that church.
- we can generalize to whole of that church because it is given that there was no bias is introduced.
Hence, the population would be set of all Christians of that particular church from where the random samples is collected.

Answer:
20 and 25.
Step-by-step explanation:
Given:
They both teach total 45 yoga classes each week.
Erica teaches 15 fewer than twice as many as Bo.
To find:
How many classes does each instructor teach per week = ?
Solution:
Let number of classes are taken by Bo = 
Then number of classes are taken by Erica = 
(given)
Total number of classes are taken by both = 45 (given)
According to the question.
+ = 45
By adding both side by 15
By dividing both side by 3
number of classes are taken by Bo = = 20
number of classes are taken by Erica =
= 
Therefore, number of classes are taken by Bo and Erica is 20 and 25.
Answer:
Number 2 is 3:4.
Number 1 is d.
Step-by-step explanation:
Boxers and collies added together gives you 12:16. Divide them both by 4 and you get 3:4.
<
The number of student in class 4 (6) divided by the total number of kids in the entire class (18) gives you 0.33333333333. Multiply that by 100 and it gives you 33.3333333333. As a percentage it is 33 1/2 %
