Answer: 1068
Step-by-step explanation:
Formula of sample size :
, where p = prior population proportion , E = margin of error , = Critical z- value.
Let p = proportion of visitors who are repeat visitors.
Given : p=0.5
E= 3%= 0.03
critical z-value for 95% confidence = 1.96
Now,
[round to the next integer]
Hence, the required sample size = 1068
9/27 is equivalent to 2/27
It depends on how many days you are going to be on your camping trip if you are going to be on the for 2 days you will need the 2 bottles but if you are going on the trip for 8 days you will need the 8 cans. so 8 will work
Answer: 8 times
Step-by-step explanation:
There are 1/6 chance everytime you roll, so if you x48 is is 48/6 which is 8 times!
Answer:
D (3/2
Step-by-step explanation:
<u>Simplify both side of the equation</u>: 5(4x - 10) + 10x = 4(2x - 3) + 2(x - 4)
(5)(4x) + (5)(−10) + 10x = (4)(2x) + (4)(−3) + (2)(x) + (2)(−4)
Then you distribute: 20x + −50 + 10x = 8x + −12 + 2x + −8
(20x + 10x) + (−50) = (8x + 2x) + (−12 + −8)
Combine like terms: 30x + −50 = 10x + −20
30x - 50 = 10x - 20
<u>Subtract 10x from both sides</u>: 30x − 50 − 10x = 10x − 20 − 10x
20x - 50 = -20
<u>Add 50 to both sides</u>: 20x - 50 + 50 = -20 + 50
20x = 30
<u>Divide both sides by 20</u>: 20x / 20 = 30 / 20
<em>x = 3/2</em>
