Answer:
3 months
Step-by-step explanation: Let after m months they saved same amount of money.
Given,
Saving of Jaclyn = $ 120,
Amount earned by him/her per month = $ 40,
So, the total amount contained by him/her in m months = Saving + earning for m months
= 120 + 40m,
Similarly, saving of Pedro = $ 180,
Amount earned by him/her per month = $ 20,
So, the total amount contained by him/her in m months = 180 + 20m
Thus, we can write,
120 + 40m = 180 + 20m
40m = 180 + 20m - 120
40m - 20m = 60
20m = 60
⇒ m = = 3.
Hence, it will take 3 months before which Jaclyn and Pedro have saved the same amount of money.
I would say that the graph shows a positive association since both the numbers go up. A liner association would be more straight, (2,18) would be the correct coordinates of the outlier and there is definitely an association I would say.
Hope this helps! (:
Answer:

Step-by-step explanation:
Product Rule of Exponents aman = am + n
When multiplying exponential expressions that have the same base, add the exponents.
Example:
Multiply: 4x3 · −6x2
Solution:
Multiply coefficients: 4 · −6 = −24
Use the product rule to multiply variables : x3 · x2 = x3 + 2 = x5
4x3 · −6x2 = −24x5
Subtract
3y = 12
y = 4
2x - y = 6
2x - 4 = 6
2x = 10
x = 5
solution (5,4)
answer is D. (5.4)
If you add the standard deviation to the average, it is 14.84. Because Marcus's score was lower than that, he will not receive a certificate.
I think this should be right for the reason and the calculation.
