You would subtract 3 from 5 getting 2 and multiply 2 by itself getting the Answer: 4
Work: (5-3)= 2^ of 2 or 2*2 = 4
Answer:
The sample proportion is 0.158.
Step-by-step explanation:
In a confidence interval of proportions, we have the lower bound and the upper bound of the interval. The sample proportion is the halfway points between these bounds, that is, the sum of these bounds divided by 2.
In this problem, we have that:
Lower bound: 0.142
Upper bound: 0.174
Sample proportion: (0.142+0.174)/2 = 0.158
The sample proportion is 0.158.
The bottom is 2 times the size of the first one
2 (2x - 9) = 14
Distribute
4x - 18 = 14
Add 18
4x = 32
Divide by 4
x = 8
Answer:
-7y
Step-by-step explanation:
-2y-7y=
-9y+8y=
-y+y=
0-7y=
-7y
Answer:
see below
Step-by-step explanation:
y = 3/4x + 3
To find the y intercept, let x =0 and solve for y
y = 0+3
The y intercept is 3
To find the x intercept, let y =0 and solve for y
0 = 3/4x+3
-3 = 3/4x
-3 *4/3 = 3/4x*4/3
-4 =x
The x intercept is -4
