the answer for this question is 19 because you add them up and subtract the 7th graders
The answer is w=5 how I got it was u add 10 to both sides than minus seven to both sides than u divide and u get w=5
The missing digits is highlighted in bold form
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)
Assume it is first down and ten in this problem. When you lose 5 yards on the sack, you are 5 yards further away. So now, it is second and 15. Then, they lose another 15 yards, so it's now third and 30. The final play is that they gain 12 yards, meaning after all the plays it is fourth down and eighteen yards to go.
In math symbols, 0 is where the first down marker is. You start at -10.
First play, the sack: -10 - 5 = -15
Second play: -15 - 15 = -30
Third play: -30 + 12 = -18.
Looks like you have to punt on fourth down :)
Answer:
90.8
Step-by-step explanation:
w = 80 + 5.4t (fill in your variable t, the number of months)
w = 80 + 5.4(2) (Combine parentheses first)
w = 80 + 10.8 (Add the two together)
w = 90.8 (Your answer)
I hope this helped :)
