This is some simple Algebra
So it's 4x+16=-2
We subtract 16 from both sides
4x=-18
Sivide both sides by 4
X=-4.5

Answer:
d. 60k
Step-by-step explanation:
The sample mean is the midpoint between the lower and the upper limit of the confidence interval, that is, the sum of the lower and the upper limit divided by 2.
In this problem, we have that:
Lower limit: 50k
Upper limit: 70k
(50k + 70k)/2 = 60k
So the correct answer is:
d. 60k
Answer:
15,000
Step-by-step explanation:
10x10x30
10x10=100
100x30=3,000
50x20x12
50x20=1,000
1,000x12=12,000
3,000+12,000=15,000
(7 + 5) x 6 + 3. (7 + 5 = 12, 12 x 6 = 72, 72 + 3 = 75.)
