X>44
.25(x)-3-4>4
.25(x)-7>4
.25(x)>11
x>11
Answer:
Step-by-step explanation:
12 - 12x = -6x + 48
Add 12x to both sides. That eliminates the x term on the left side.
12 = 6x + 48
Subtract 48 from both sides. That eliminates the constant term on the right side.
-36 = 6x
x = -6
z = -2.83
<u>Explanation:</u>
Given:
Mean, μ = 68
Standard deviation, σ = 6
Data point, x = 51
Z score, z = ?
We know:
Substituting the value we get:
A negative z score says that the data point is below average.
