2(-2) + 7
= -4+7
= 3
so when x = -2 y = 3

Answer:
-6mph
Step-by-step explanation:
45 is 3/4hour so -8 times 3/4= -24/4=-6mph
We cannot determine the cost of the tiles from the given information, so the question cannot be answered.
Answer:
Provided that the sample size, n, is sufficiently large (greater than 30), the distribution of sample means selected from a population will have a normal distribution, according to the Central Limit Theorem.
Explanation:
1. As n increases, the sample mean approaches the population mean
(The Law of Large numbers)
2. The standard error of the sample is
σ/√n
where σ = population standard deviation.
As n increases, the standard error decreases, which means that the error
between the sample and population means decreases.
Answer:
b. MLR.3 - No perfect collinearity assumption
Step-by-step explanation:
There is an assumption that nothing in the error term should correlate with the explanatory variable (x) of interest and outcome variable of (y). It does not allow any linear relation between two or more variables. If there is a relation between the variable it the the violation of this assumption.
