Answer:THE ANSWER IS C HOPE THIS HELPS ANY
Step-by-step explanation:
Answer:
D. We are 95% confident that the proportion of all Americans who say that race relations in this country are generally bad is between 58% and 64%.
Step-by-step explanation:
The 95% confidence interval refers that 95% of data is correct with respect of the population
Given that 95% confidence interval is (0.58, 0.64)
So based on this, the option D is correct as it shows the right thing with regard to 95% confidence interval
Therefore all the other options are incorrect as the first option is of probability, the second option is the sample, and the third option is of statement form i.e not standardized.

Answer: you travelled 10 km
Step-by-step explanation:
Pam jogged up the hill at 6 km/h.
Let x represent the number of kilometers that you travelled by jogging up the hill or returning back.
Time = Distance/speed
Pam jogged up the hill at 6 km/h.
Time spent in jogging up the hill would be
x /6
She then jog back down the hill at 10 km an hour. Time spent in jogging down the hill would be
x /10
If the total jogging tie is 1 hour 20 minutes, converting to hours, it becomes 1 + 20/60 = 1.33
Therefore
x /6 + x/10 = 1.33
10x + 6x = 80
16x = 80
x = 80/16 = 5
Total distance travelled up and down the hill would b
5 × 2 = 10 km
Answer:
x = 25
y = 6
Step-by-step explanation:
< B = < M
2x - 20 = 30
2x = 50
<u>x = 25</u>
AB = LM
7y - 8 = 2y + 22
5y = 30
<u>y = 6</u>
