Answer:
a)8
b)7
c)26
d)60
Step-by-step explanation:
The Venn Diagram is attached
For number of people who saw a single movie only
See the number associated with the movie name excluding all intersection parts
For people who watched only 2 movies exactly
Sum all the intersection parts of any 2 circle parts=6+12+8=26
For total number of students surveyed
Sum up every number in the Venn diagram including the number 5 outside 3 circles(it represents that 5 people did not watch any of the films)
=7+12+10+6+4+8+8+5=60
Answer:
(0.30, 0.42)
Step-by-step explanation:
Given the sample proportion is = 0.36
Number of trials required for determining the margin of the error = 100
Sample size, n = 50
The point estimate = 0.36
The minimum sample proportion form the simulation = 0.28
The maximum sample proportion from the simulation = 0.40
Also the margin of the error of population proportion is found by using the half of the range.
Therefore, the interval estimate for the true population proportion is = (0.30, 0.42)
The answer would be milliliter. Hope that is helpful.
Using the Fundamental Counting Theorem, there are 60 different ways to order the pizza.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with ways to be done, each thing independent of the other, the number of ways they can be done is:
For this problem, considering the sauce, the topping and the pizza format, the parameters are found as follows:
- For the sauce, there are 2 options, either cheese or tomato, hence .
- For the topping, there are 4 options, but the options may be combined, for example, Pepperoni and Sausage, hence . The subtraction by 1 is because the option of no topping is found in the third parameter.
- The topping can be added to either all the pizza or only half the pizza, hence .
Thus the number of ways for the customer to order a pizza is given by:
N = 2 x 15 x 2 = 60.

Answer:
16
Step-by-step explanation:
To find out how many sections she needs, you need to find the perimeter
24 * 2 = 48
40 * 2 = 80
48 + 80 =128
If each section of fence is 8 feet then you divide 128 by 8 and get 16
