im pretty sure the answer is y = x - 2
Answer:
The perimeter is 24 in2
Step-by-step explanation:
You have to add up all of the sides together
Answer:
1. (t + s)(u + v).
2. (m + k)(n + 3).
Step-by-step explanation:
1. tu+tv+su+sv
Note that t is common in the first 2 terms and s is common to the last 2.
= t(u + v) + s(u + v)
Now u + v is common so we have:
(t + s)(u + v).
2. mn+3m+kn+3k
= m(n + 3) + k(n + 3)
= (m + k)(n + 3).
Answer:
Mean $1060
Standard error $34.69
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation, which is also called standard error, .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Population:
Mean $1,060 and standard deviation $190.
Sampling distriution of samples of size 30:
Mean $1060
Standard deviation
