The correlation coefficient between two quantitative variables is approximately 0.02. What does the value of this correlation coefficient indicate about how well the model
fits the data?
O A. The correlation coefficient is not within the correct range.
O B. The model is a good fit.
OC. No conclusion can be drawn regarding how well the model fits the data.
The model is not a good fit.
Answer:
The model is not a good fit
Step-by-step explanation:
The correlation Coefficient is a metric used to evaluate the strength of the relationship between 2 variables, the correlation Coefficient ranges from - 1 to + 1 with values closer to either ±1 depicting the strongwr and better relationship. A value of 0 means no relationship exists and values close to zero means the relationship is weak. Wutb a correlation Coefficient value of 0.02, this value is very close to 0 and hence shows that the relationahip is extremely weak. Hence, the model is not a good fit.

How to find the missing dimensions of a prism
Answer:
Below.
Step-by-step explanation:
You need to know the volume or total surface area of the prism and 2 of the dimensions.
The formula for the volume = wlh where w = width , l = length and h = height.
So knowing say w = 4, l = 8 and V = 192 we have:
V = wlh
192 = 4 * 8 * h
h = 192/4*8
= 192/32
= 6.

If triangle MNO and triangle PQR are similar, which of the following must be true?
Answer:
C and D
Step-by-step explanation:
Want explanation? Comment
Answer:
D
Step-by-step explanation:
It looks like triangle MNO and PQR are similar because PQR is a smaller version of MNO reversed. If this is true, MN is equal to PQ, OM is equal to RP, and ON is equal to RQ. Therefore, the answer should be D.

A car that is purchased got 24000 is expected to depreciate at a rate of 7% per year. If the function f(x)=ab^x models this situation, which function could be used to find the value of the car after 10 years?
Answer:
FV= 24,000*(1.07^-10)
Step-by-step explanation:
Giving the following information:
Present Value (PV)= $24,000
Decrease rate (d)= 7%
Number of periods (n)= 10 years
To calculate the value of the car after 10 years, we need to use the following formula:
FV= PV*(1+d)^-n
FV= 24,000*(1.07^-10)
FV= $12,200.38

Find the surface area of the triangular prism shown below. 10 10 8 14 12
Answer:
Hello! answer: 544
Hope this helps!
The surface area of the given triangular prism is 544 units³
What is a triangular prism?A triangular prism is a polyhedron made up of two triangular bases and three rectangular sides.
Given that are the dimensions of a triangular prism, we are asked to find its surface area,
Surface area = (perimeter × length)+(base area)
Surface area = [(10+10+12)×14]+(8×12)
= 32×14+96
= 448+96
= 544
Hence, the surface area of the given triangular prism is 544 units³

3x² + 7x + 6
Step-by-step explanation:
Big Rectangle:
A = bh
A = (x + 3)(x + 2)
A = x² + 2x + 3x + 6
A = x² + 5x + 6
Small rectangle:
A = bh
A = (x + 1)(2x)
A = 2x² + 2x
