To find the equation we have to divide the rates:
( 3 v³ - 2 v + 20 ) : ( v + 2 ) = 3 v² - 6 v + 10
-3 v³ - 6 v²
----------------
- 6 v² - 2 v
6 v² + 12 v
-------------------
10 v + 20
- 10 v - 20
---------------
r ( x ) = 0
Answer: C ) 3 v² - 6 v + 10
Answer:√(6/5) and √(9/7) and √(7/5)
Step-by-step explanation:
1/4 = 0.25
5/4 = 1.25
√(6/5)=1.095445...
√(9/7)=1.1338934...
√(7/5)=1.1832159...
Thus, any non-perfect square radicals will be irrational numbers.
Hope this helps!! :)

Answer:
The approximate probability that the mean of the rounded ages within 0.25 years of the mean of the true ages is P=0.766.
Step-by-step explanation:
We have a uniform distribution from which we are taking a sample of size n=48. We have to determine the sampling distribution and calculate the probability of getting a sample within 0.25 years of the mean of the true ages.
The mean of the uniform distribution is:
The standard deviation of the uniform distribution is:
The sampling distribution can be approximated as a normal distribution with the following parameters:
We can now calculate the probability that the sample mean falls within 0.25 from the mean of the true ages using the z-score:
A) $94
b) S=8w+54
c) 116=8w+54
-54. -54
62=8w
7.75=w
8 week because she is depositing at the end of the week
The top right one is the answer. I hope this helps
