Answer:
4 hours and 10 min
Step-by-step explanation:
For this equation we will do ratios:
250 min =
4 hours and 10 min
4(60) = 240
240 + 10 = 250 minutes
5/8 - 2/8 = 3/8, and 3/8 simplify into 0.375, so he have 0.375 pounds of trail mix left.
Answer:
C
Step-by-step explanation:
As x approaches positive infinity, the negativity of f(x) increases.
you can try by putting values 5 and 10 into x and notice how f(x) approaches negative infinity

A study done by researchers at a university concluded that 70% of all student-athletes in this country have been subjected to some form of hazing. The study is based on responses from 1800 athletes. What are the margin of error and 95% confidence interval for the study?
Answer:
Step-by-step explanation:
Given that:
The sample proportion
The sample size n = 1800
At 95% confidence interval level:
The level of significance = 1 - 0.95 = 0.05
Critical value:
Thus, the Margin of Error E =
the Margin of Error E = 0.021
At 95% C.I for the population proportion will be:
= 0.70 ± 0.021
= (0.70 - 0.021, 0.70 + 0.021)
= 0.679, 0.721)
