Step-by-step explanation:
<u>Proportional relationship equation:</u>
- y = kx, where k- constant of proportionality
<u>Use the given point to work out the value of k:</u>
<u>In our case the equation is:</u>
- v = 5.6m, where v- volume, m- mass

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.
Answer:
f = -8
Step-by-step explanation:
7(f+3)+9=5(f-2)-3f
7f + 21 + 9 = 5f - 10 - 3f
7f + 30 = 2f - 10
5f = -40
f = -8
Answer:
Experimental Probability = 1/3
Theoretical Probability = 1/6
========================================================
Explanation:
Count how many times the number "2" shows up in the "Result" column. There are 4 instances of this value. This is out of 12 trials total.
Divide the two numbers to get 4/12 = 1/3 as the experimental probability
-------------
In contrast, the theoretical probability is 1/6 because there's 1 side labeled "2" out of 6 sides total.
The decimal form of each fraction is:
1/3 = 0.333 approximately
1/6 = 0.167 approximately
