Answer:
0.6210
Step-by-step explanation:
Given that a Food Marketing Institute found that 39% of households spend more than $125 a week on groceries
Sample size n =87
Sample proportion will follow a normal distribution with p =0.39
and standard error = 
the probability that the sample proportion of households spending more than $125 a week is between 0.29 and 0.41
=
There is 0.6210 probability that the sample proportion of households spending more than $125 a week is between 0.29 and 0.41
The vertex is (-1.5, -6.75). So the x-coordinate is -1.5. Hope this helps and if so please leave a good rating and thanks. I really appreciate it. Have a nice day!

Answer:
1. 10 6/7 2. 8/15
Step-by-step explanation:
1. 6 1/42 + 4 5/6
- First, let's combine the whole numbers. 6 + 4 = 10
- Now we are left with 1/42 + 5/6.
- To add or subtract, the dominators need to be the same. We need to find the least common multiple which here is 42.
1/42 + 5/6(7)
1/42 + 35/42
= 36/42
= 6/7
- All we have to do is combine both numbers.
10 6/7
2. 13/15 - 1/3(5)
13/15 - 5/15
8/15
1) (solve for Y 1st)
-4y=16
y=-4
slope=0 y-inter= -4
2)(solve for X 1st)
6x=12
x=2
slope=undefined y-inter= none
