G is the answer because if you set x as the value of B, then x+(x+10)+(x+30)=180 so x=46.67. then you add 10 to that because the value of A is 10 more than B
Answer:
Reject H0 if x > cv
Step-by-step explanation:
The hypothesis :
H0 : μ ≤ 425
H1 : μ > 425
Standard deviation, s = √2500 = 50
Sample size, n = 100
xbar = 433.5
The test statistic, Z :
(xbar - μ) / s/√n
(433.5 - 425) / 50/10
Z = 8.5 / 5 = 1.7
The decision region ;
|Z| > Z0.01 ; Reject H0
From Z table ;critical value, Z0.01 = 2.33
1.7 < 2.33 ; We fail to reject then Null and conclude that thee is no significant evidence support the claim that population mean income has increased.
Answer:
17. 42
18. 12
19. 12
20. 12
Step-by-step explanation:
Simply substitute the given values into the variables. So if m = 6 and n = 2:
7m = 7(6) = 42
6n = 6(2) = 12
mn = (6)(2) = 12
3m - 6 = 3(6) - 6 = 18 - 6 = 12
I believe it is y=mx+b..........y equals slope times x plus the y intercept...or y=-8/3x+4.that would mean your slope would be negative. meaning it would go from the left top hand corner and fall through to the bottom right hand corner.
