Answers
The most likely correlation coefficient of the data set is: C. 0.19.
What is the Correlation Coefficient of a Data Set?
On a scatter plot, the farther apart the data points are from each other, the farther the correlation coefficient would be from 1 or -1.
Also, a if the slope of the scatter plot increases from left to your roght upwards, the correlation coefficient of the data set would be positive.
The scatter plot that is given shows this patern, therefore, the most likely correlation coefficient of the data set is: C. 0.19.

Answer:
Vertex of parabola (-1, -10)
Step-by-step explanation:
For a given quadratic y = ax² + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k. If you've already learned the Quadratic Formula, you may find it easy to memorize the formula for k, since it is related to both the formula for h and the discriminant in the Quadratic Formula: k = (4ac – b2) / 4a.

first bit
mean of 12 numbers is 5.5 is the same as
(12 numbers)/12=5.5
the second bit
mean of 8 numbers is k
(8 numbers)/8=k
(12numbres+8numbers)/20=8.5
interesting
one way is to solve the first and second equations for 12numbers and 8numbers
(12numbers)/12=5.5
times 12 both sides
12numbers=66
(8numbers)/8=k
multiply 8 both sides
8numbers=8k
input
(66+8k)/20=8.5
mulitply both sides by 20
66+8k=170
minus 66 both sides
8k=104
divide 8 both sides
k=13
k=13
You do (8.5 X 20) - (5.5 X 12), which is equal to 170 - 66 = 104
104 divided by 8 equals 13

vicki worked a fraction(that's greater than 1) of stacey's time. since it is greater than 1, it makes it more so like 2 times 2 and 1/2=2+1=3 which is greater so
viki worked more than stacy therefor
josh<stacy<vicki
so
A is correct (Stacey>josh)
B is correct (Stacey<Viki)
C is false
D we have to solve by doing
4 and 3/4 convert to fraction improper
4 and 3/4=19/4
19/4 times 2/3=josh=38/12=19/6
viki worked 1 and 3/8 of stacey
19/4 times 1 and 3/8=19/4+57/32=209/32=7.9
josh+stacey=19/4+19/6=95/12=6.5
7.9>6.5 so
D is true
so the answers that are true are
A,B,D
2a is true and 2b is also true and 2c is false 2d is true
