Answer:
1. 424
2.471
3.512
Step-by-step explanation:
1. 10×12+8×10+8×13+8×15
=120+80+104+120
=424
2. 5×24+9×24+9×15+9×15
=120+216+135
=471
3. 24×16+2×24+2×20+2×20
=384+48+40+40
=512
<h3>
Answer: 18 miles</h3>
Reason:
The path is 2 miles and Randy walked it 13 times. He walked a total of 2*13 = 26 miles.
Carla walked the path 22 times, so she walked a total of 2*22 = 44 miles.
The difference of those results is 44-26 = 18 miles.
If you wanted to do the full calculation in one line, then it would be
2*22 - 2*13 = 18
or you could say
2*(22-13) = 18
Answer:
A. 2
Step-by-step explanation:
Using the z-distribution, it is found that the lower bound of the 99% confidence interval is given by:
d. 68.39%.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
is the sample proportion.
In this problem, we have a 99% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 2.575.
The sample size and estimate are given by:

Hence, the lower bound is given by:

Hence the lower bound is of 68.39%, which means that option D is correct.
