Answer:
21
Step-by-step explanation:
Answer: Part A:
We observe that we have the following system of equations:
y = 4x
y = 2x-2
The solution to the system of equations is an ordered pair (x, y), that is, a point in common that both functions have.
Part B:
x y = 4x y = 2x-2
-3 -12 -8
-2 -8 -6
-1 -4 -4
0 0 -2
1 4 0
2 8 2
3 12 4
The solution is the ordered pair:
(x, y) = (-1, -4)
Part C:
See attached image
Step-by-step explanation:
90y - 10x - 10
First, find the greatest common factor (GCF)
10 is the largest number that divides evenly into 90y, -10x, and -10.
The GCF is 10.
Second, factor out the GCF.
Put the GCF as the first term
In parentheses, divide each term by the GCF
Third, simplify each term in the parentheses. / Your problem should look like: 10(9y - x - 1)
Answer:
10(9y - x - 1)
Answer:
18
Step-by-step explanation:
24x0.75=18(75%=0.75)
Answer:
The p-value for two-tailed test is 0.136
Step-by-step explanation:
Given;
one-tail test, p-value = 0.068,
In one-tailed test, we test for the possibility of a relationship in one direction and completely disregard the possibility of a relationship in the other direction.
One-tail test provides possibility of an outcome in one direction, while
two-tail test provides possibility of an outcome in two different directions.
Thus, the p-value for two-tailed test = 2 x 0.068 = 0.136
