Answer: 0.750
Step-by-step explanation:
Let p be the population proportion .
We are given that a sample of 400 voters reveals that 300 would support her in the November election.
Then the sample proportion for this situation will be :-

Since the sample proportion is the best point estimate for the population proportion.
Therefore, the estimated value of the population proportion =0.750
2(x+3)= 3x-1
2x+6=3x-1
X=7
Therefore
YM = 7+3= 10
And by definition of midpoint YM=MZ so MZ=10
Answer:
y=8x-29
Step-by-step explanation:
Since we know the slope (m) is 8, we can plug it in the slope-intercept formula y=mx+b, making y=8x+b.
Now we need to find the y-intercept (b). To do that, you would need to plug in the points given to you, which were (4,3).
x=4, y=3... so 3=8(4)+b
Now you can solve for the variable b to find the y-intercept.
3=8(4)+b, multiply...
3=32+b, subtract 32 on both sides...
-29=b
Therefore, the y-intercept, or b, is -29.
The equation would be y=8x-29
1265/34=37.2
Since the number of shelves needs to be integer number, so he needs 38 shelves.
