28 = 4(4x-5)
x would be 3 in this case
Answer:H Is your answer
Step-by-step explanation:
Eight times the quantity of a number and six.
8 (x+6)
Answer:
a) x=12
b) x=8.71
c) x=10.95
d) x=3.92
e) x=5.152
Step-by-step explanation:
a) x=12.
To have a probability of 0.5, x must be the mean of X.
b) x=8.71
c) x=10.95
d) x=3.92
If we define Y=X-12, then
For z=1.96, the probability around the mean is 0.95. Then:
e) x=5.152
As in the question d, the area around the mean now is 0.99. This happens when z=2.576. Then:
9514 1404 393
Answer:
(A) -7
Step-by-step explanation:
The function is continuous if you can draw its graph without lifting your pencil. In this case, that means each of the piecewise function definitions must have the same value at x=3.
x^2 +2 = 6x +k . . . . . must be true at x=3
3^2 +2 = 6(3) +k . . . . substitute 3 for x
9 +2 -18 = k . . . . . . . . subtract 18
k = -7 . . . . . . . simplify
