Answer:
<h2><u>
2 miles per hour</u></h2>
Step-by-step explanation:
Speed = Distance / Time
If we measure distance in miles and time in hour, we will get the speed in miles per hour.
Distance = 1 + 2/3 miles, which expressed as an improper fraction is 5/3 miles.
Time = 50 minutes which expressed in hours will be 50/60 or 5/6 hours.
(You can also see that 10 minutes is 1/6 of an hour, hence 50 minutes is 5/6 of an hour)
Speed = Distance / Time
= (5/3) / (5/6)
We know that dividing by "a/b" is same as multiplying by "b/a"
Hence, we have:
Speed = (5/3) * (6/5)
= (5 * 6) / (3 * 5)
= 30 / 15
= 2

Answer:
Step-by-step explanation:
<u>To find it we will divide:</u>
- 4 x 10^16 / 4 x 10^6 =
- 4/4 x 10^(16 - 6) =
- 1*10^10=
- 10^10 times
The first number is 10^10 times larger
Answer:
We fail to reject the null hypothesis at 0.05 significance level. We cannot say that less than 12% of trips include a theme park visit.
Step-by-step explanation:
let p be the proportion of trips included a visit to a theme park.
: p=0.12
: p<0.12
To test, we need to calculate test statistic of the sample proportion as:
z=
where
- p(s) is the sample proportion of trips included visit to a theme park (
- p is the proportion assumed under null hypothesis. (0.12)
- N is the sample size (1565)
Using the numbers, z=
= −0.767 and p(z) is ≈0.222
Since 0.222 > 0.05 we fail to reject the null hypothesis.
