Answer:
Formula: (cost of ticket + cost of popcorn) * # of friends = total cost
Which would give us (8 + x) * 5 = 62.5
Solve for x.
8 + x = 12.5 {divide each side by 5}
x = 12.5 - 8
x = 4.5
Each small bag of popcorn costs $4.50.
I think that’s a brand of tape beacuse there’s duck tape, scotch tape, paint tape, washie tape etc
Hope this helps:)
Answer:
C) a sample distribution of a sample mean with n = 10
and
Step-by-step explanation:
Here, the random experiment is rolling 10, 6 faced (with faces numbered from 1 to 6) fair dice and recording the average of the numbers which comes up and the experiment is repeated 20 times.So, here sample size, n = 20 .
Let,
= The number which comes up on the ith die on the jth trial.
∀ i = 1(1)10 and j = 1(1)20
Then,
=
= 3.5 ∀ i = 1(1)10 and j = 1(1)20
and,
=
=
=
15.166667
so, =
= 2.91667
and =
Now we get that,
We get that are iid RV's ∀ j = 1(1)20
Let,
So, we get that
= for any i = 1(1)10
= 3.5
and,
Hence, the option which best describes the distribution being simulated is given by,
C) a sample distribution of a sample mean with n = 10
and
Around 0.02 or more precise, 0.02083
Notice the pattern of the out bags. For every person after the first, three more bags are pulled. By continuing this pattern you will eventually find the answer
1=2
2=5
3=8
4=11
5=14
6=17
7=20
8=23
9=26
10=29
11=32
Therefore, you need 11 people to get the job done in one day
