Answer:
<u><em>Part A:</em></u> D.
<u><em>Part B:</em></u> C.
Step-by-step explanation:
For part A) we just have to plug in 0 for x and solve for y until we find the equation that says 3 is the value for y when x is 0. For purposes of speeding up the process the correct answer is D. I will show how to check for it now.
The equation:
Now plug in 0 for x.
Now solve.
y = (1)(3)
y = 3
This proves that this is the correct answer.
For part B) we just have to plug in the give values for x separately and check for each value of x that it equals 0. For the purpose of speeding up the process the correct answer is C. I will show how to check for it now.
The equation:
Now plug in x for 0 and solve:
This equation is true, now we check for the other value of x, 3.
This is also true so that means this is the correct answer.
Answer:
f=11
Mode=4
Median=4
Explanation:
We are given that
a.Mean of the exam score,=3.5
Score(x) frequency C.F
1 1 1
2 3 4
3 f 15(4+f=4+11)
4 13 28
5 4 32
Using the formula
b.Mode:The number which is repeat most times .
4 repeat most times
Hence, mode of all exam scores=4
N=32
N is even
Median=
