Answer:
26
Step-by-step explanation:
We can work backwards using the z-score formula to find the mean. The problem gives us the values for z, x and σ. So, let's substitute these numbers back into the formula:
z−4−16−2626=x−μσ=10−μ4=10−μ=−μ=μ
We can think of this conceptually as well. We know that the z-score is −4, which tells us that x=10 is four standard deviations to the left of the mean, and each standard deviation is 4. So four standard deviations is (−4)(4)=−16 points. So, now we know that 10 is 16 units to the left of the mean. (In other words, the mean is 16 units to the right of x=10.) So the mean is 10+16=26.
Answer:
8p + 4
Step-by-step explanation:
6p + 4 + 2p
(6p + 2p) + 4
8p + 4

Answer:
is there a picture to this problem?
3 can be squared twice to get the value of 9. 3x3=9
The answer to this would be 4^3 or 4×4×4.
This equals 64. So there are 64 chairs in thé building.
