B) y = -1/3 + 17
A line is perpendicular to another when the slope of one is the negative reciprocal of another line
example: negative reciprocal of x is -1/x
Answer:
a)0.154<p<0.48[
b)n≅ 6.57
c)n=2401
Step-by-step explanation:
n = 60
Sample proportion = p = 16/60 = 0.266
a) Find a 95% two-sided confidence interval on the true proportion of helmets
90 % confidence interval fro population is
hence population proportion lies in the confidence interval
b) helmets must be tested to be 95% confident
point of estimates i s- 0.266
Margin of error = 0.02
after putting values we get
n = 6.56
n≅ 6.57
c)large must the sample be
The sample is calculted as
n=2401
Which number, when rounded to the nearest whole number and to the nearest tenth, rounds to the same value?
1.63
5.46
4.95
2.12

To determine how much you get per hour, divide 44 by 4, 88 by 8, and 132 by 12. Each time you get 11, so you get 11 dollars an hour.
If y = money earned and x = number of hours worked, then
y=11x
because the money you get is 11 times the amount of hours you work.
Hope this helps and I can provide further explanation if needed!
