Answer:
0.6758
Step-by-step explanation:
Given That:
Population Mean pulse rate (μ) = 69
Sample size (n) = 162
Sample mean (m) = 69.6
standard deviation (σ) = 11.3
Value of test statistic :
(m - μ) / (σ/√n)
(69.6 - 69) / (11.3 / √162)
0.6 / 0.8878118
= 0.6758

Janet enjoys reading books, and reads an average of 4 books a month. Janet's younger brother, Alex waited for a month before deciding he liked reading, and also reads at an average of 4 books a month. If m represents the number of months Janet has been reading books, the equation 4m=4(m−1) represents the situation where Alex and Janet have read the same number of books.
Solve the equation to find the number of months it will take for Alex and Janet to have read the same number of books. Show your work.
Answer:
No solution
Step-by-step explanation:
4m = 4(m - 1)
Distribute;
4m = 4m - 4
Subtract 4m from both sides;
0 ≠ -4
No months because Alex cannot catch up to Janet since they both read the same amount of books per month.
Answer: They will never have read the same number of books
Step-by-step explanation:
4(m-1) will always be less than 4m no matter what.

What is the x -intercept of x+4y=7?
Answer:
I believe it is (7, 0)
Step-by-step explanation:
I hope this is right..
Answer:
use slope intercept form to find the x intercept
y = Mx +b
Step-by-step explanation:
x+4y=7
4y= -x+7
y= -1/4x +7/4
so when this line is on the x intercept.. then y =0 soooo plug in zero for y and solve
0= -1/4x + 7/4
-7/4 = -1/4x
7 = x

Multiplicative inverse of -3 6/11 ? In fraction form- please and thank you ^^
Answer:
Step-by-step explanation:
first you have to make this an improper fraction my multiplying -3 by 11 then add the product of that to 6 and put it all over 11
[tex]-3\frac{6}{11}[/tex] → [tex]-\frac{39}{11}[/tex]
once you get this you have to do the reciprocal of this to get them to equal 1
[tex]-\frac{39}{11}[/tex] → [tex]-\frac{11}{39}[/tex]
then multiply the number by the reciprocal
[tex]-\frac{39}{11}* -\frac{11}{39}=\frac{429}{429}=1[/tex]

A restaurant recorded what items from the kids menu were ordered on Friday night. Twenty-eight of the 76 kids at the restaurant Friday night ordered chicken nuggets. What is the ratio of kids who did not order chicken nuggets to the number of kids who did? Write your ratio in simplest form.
Answer:
12:7
Step-by-step explanation:
Total number of kids = 76
Total number of kids that ordered chicken nuggets = 28
Total number of kids that did not order chicken nuggets = 76 - 28
= 48
The ratio of kids who did not order chicken nuggets to the number of kids who did is:
= 48 : 28
In simplest form :
= 12:7
