Answer:
The margin of error for the proportion of students at OSU who have ever used an online dating app in 99% confidence level is 10.8%
Step-by-step explanation:
margin of error (ME) around the mean can be found using the formula
ME=
where
- z is the corresponding statistic in the given confidence level (2.58)
- p the proportion of students at OSU who have ever used an online dating app in the random sample. (0.43)
- N is the sample size (140)
Putting the numbers in the formula we get
ME=
≈ 0,10795 ≈ 10.8%
Then the confidence interval for the proportion of students at OSU who have ever used an online dating app in 99% confidence level would be 43%±10.8%
Speed = distance / time
Speed = 50 miles / 4 hours
Speed = 12.5 miles per hour
Answer:
C. 10.5 pounds
Step-by-step explanation:
The worth of 3 loaves of bread is 3 times that of one loaf:
3 × 1.75 = 5.25
You want the number of pounds of oranges (p) at 0.50 per pound that has this same worth:
0.50p = 5.25
p = 5.25/0.50 = 10.50
10.5 pounds of oranges have an equivalent cost to 3 loaves of bread.
I believe its asking to find X, Im sorry if Im wrong and its something else, the question confuses me.
1) x = 16
2) x = 16
3) x = 16
X always equals 16
____________________________
EXPLANATION
x/2 - 5 = 3
16/2 - 5 = 3
8 - 5 = 3
3= 3
x/2 = 8
16/2 = 8
8 = 8
x = 16
16 = 16
