2 movies
4 hours - .5 popcorn -1.75-1.75=0
Easier terms 4 hours minus 30 min is 3 hours and 30 min left each movie is 1 hour and 45 min plus 1 hour 45 min i that's 2 hours and 90 min 90 min are one hour and 30 min. So 2 hours plus one hour and 30 min is the 3 hours and 30 min are we're left
By using cross multiplication x= 3×7÷5=4.2
the answer is 4.2
The answer is A.0
hope this helped
Answer:
The 99% confidence interval for the proportion of athletes who graduate is (0.5309, 0.7323).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
For this problem, we have that:
99% confidence level
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 99% confidence interval for the proportion of athletes who graduate is (0.5309, 0.7323).
Answer:
The answer would be -10p+30.
Step-by-step explanation:
Distrubuting the 5 to -3p and 7 and 5 to p and -1 would be the first step.
Once you did that, you would get -15p+35+5p-5. Now just add -15p to 5p and add 35 to -5 and you'll get -10p+30.
