X = 3 That is the answer.
Step-by-step explanation:
The plot with the points closest to being on the same line will be the plot with the highest correlation, or strongest association.
3(x2+2)-3y
3((2)^2+2) - 3(2/3)
first exponents,
3(4+2) - 3(2/3)
then parenthesese
distribute 3
12 + 6 - 2
18 - 2
16
Answer:
0.02
Step-by-step explanation:
Given a normal distribution :
Mean income (m) = 25000
Standard deviation of income (s) = 6000
X ≥ 12000
Using the relation to fund the standardized score :
Zscore =(x - m) / s
Zscore = ( 12000 - 25000) / 6000
Zscore = -13000 / 6000
Zscore = - 2.167
Using a z probability calculator :
P(Z ≤ - 2.167) = 0.015117
= 0.02
Answer:15
Step-by-stepFirst divide 10 by 2 which is 5% of the choose another if it’s going to be -5. Then multiply 5 by 3 which is 15 but since it’s -5 then it’s going to be -15
