Answer:
It's below in the explanation
Explanation
1. x has to be greater than 2. So 3 and 4 both work
2. x has to be less than 22. So 21 and 20 both work
3. t has to be less than 5. So 3 and 4 both work
4. There isn't a number there. what is 5 less that?
5. j has to be less than 5 so 5 and 4 both work
6. y has to be less than 4. So 4 and 3 both work
7. B has to be greater than 26. so 26 27 and 28 all work
8.There isn't a number there
9.b can be 3 or greater than 3.
10.z can be 6 or greater than 6
Hope this Helps!

Remember:
A STATISTICAL QUESTION has variable answers.
Ex: How many toys are in the U.S?
A NON-STATISTICAL QUESTIONS have only one answer
Answer:
The x-intercept is found by setting y = 0, because that will give us the x-value at which the line crosses the x-axis
Step-by-step explanation:
Answer:
The mean is also increased by the constant k.
Step-by-step explanation:
Suppose that we have the set of N elements
{x₁, x₂, x₃, ..., xₙ}
The mean of this set is:
M = (x₁ + x₂ + x₃ + ... + xₙ)/N
Now if we increase each element of our set by a constant K, then our new set is:
{ (x₁ + k), (x₂ + k), ..., (xₙ + k)}
The mean of this set is:
M' = ( (x₁ + k) + (x₂ + k) + ... + (xₙ + k))/N
M' = (x₁ + x₂ + ... + xₙ + N*k)/N
We can rewrite this as:
M' = (x₁ + x₂ + ... + xₙ)/N + (k*N)/N
and (x₁ + x₂ + ... + xₙ)/N was the original mean, then:
M' = M + (k*N)/N
M' = M + k
Then if we increase all the elements by a constant k, the mean is also increased by the same constant k.
Y = 18 x² + m x + 2
Exactly one x - intercept is for:
D = m² - 4 · 18 · 2 = 0
m² - 144 = 0
m² = 144
Answer:
m = -12 or m = 12
