According to a Niclsen survey, 92% of consumers around the world say that they trust recommendations from
friends and family most, above all other forms of advertising. Suppose we took random samples of n = 100
consumers from this population and computed the proportion of consumers in each sample who trust
recommendations from friends and family most.
What will be the shape of the sampling distribution of the proportions of consumers who trust
recommendations from friends and family most?
Choose 1 answer:
Skewed to the left
©
Skewed to the right
Approximately normal
Uniform
Answer:
what grade?
Step-by-step explanation:
The shape of the sampling distribution of the proportions of consumers will be skewed to the left. Hence, option A is correct.
What is Probability?Probability is calculated as the proportion of favorable events to all potential scenarios of an event. The proportion of positive results, or x, for an experiment with 'n' outcomes can be expressed.
As per the given information in the question,
Proportion = 92% = 0.92
Sample size, n = 100
As,
np = (100)(0.92) = 92
Use the equation given below,
n(1 - p)
= 100(1 - 0.92)
= 100 - 92
= 8
n(1 - p) = r < 10
When sampling distribution have fewer than 10 expected failure per sample, distribution of sample is left skewed.

Ned caught 1/3 pound of fish. Sarah caught 5/12 pound of fish. Jessica caught 1/6 pound of fish. How much fish did all three of them catch?
Answer:
They caught: 11/12 pounds of fish
Explanation:
First, you need to change them to the same common denominator. Since 3 and 6 already go into 12, you just have to change 1/3 and 1/6 to a denominator with 12.
First, you need to change 1/3 to 4/12. By doing that, you do 1/3x4/4=4/12.
You then have to change 1/6 to 2/12. By doing that, you do 1/6x2/2=2/12.
Then you just add up all the fractions and simplify 4/12+2/12+5/12=11/12.
You can't simplify 11/12 any further so your answer would be:
They caught 11/12 pounds of fish in total.
Answer:
11/12 pound of fish
Step-by-step explanation:
you have to find the lowest common denominator which is 12, turn them all to twelve you get 4/12 for Ned, 5/12 for Sarah and 2/12 for Jessica
add them to get 11/12!
Mr. Lin received a box of books in the shape of a rectangular prism. The volume of the box is 486 in? What is the width of the

27 inches
Answer:
9 inches.
Step-by-step explanation:
Volume = length * height * width
486 = 18 * 3 * w
w = 486 / (18*3)

5% * 120 = 0.05 * 120 = 6
6 * 2 years + 120 = 132
Answer: 132
Step-by-step explanation:
First you have to find out what 5% of 120 is. You do this by turning the percent into a decimal Like shown below.
0.05*120=6
Btw 5% as a percent is 0.05

What is the volume of a cone?The volume of the cone is the product of one-third of the height, pie, and square of the radius.
The volume of the cone = 1/3πr^2 h
We need to find the volume of a cone diameter of 12 m and a height of 6m.

on the left side of the triangle, it says 12 cm, for the right side of the triangle, it says 17 cm, below the triangle, it says 12 cm. find the area of the triangle and answer the question in square cm.
Answer:
The area of this triangle is 72 cm².
Step-by-step explanation:
We know all 3 lengths of this triangle (12, 12, 17), but all we need to answer this question is sides a and b (12, and 12).
The formula to find the area of a triangle is A = bh/2. Substitute b and h for 12 and 12 respectively.
A = (12 * 12)/2
A = 144/2
A = 72 cm²
The area of the triangle is 72 cm².

An aquarium is on sale for $59.50. If this price represents a 15% discount from the original price, what is the original price to the nearest cent?
Answer: The original price is $70.00
Step-by-step explanation:
The problem states that $59.50 is the discounted price, this means that it is not the 100% price of the aquarium. Since 15% is the discount, the remaining price is equivalent to 85% of the original price, which amount to $59.50.
100% - 15% = 85%
100% - 15% = $59.50
To get original price, we must divide the discounted price by its corresponding percentage.
$59.50 / 85% = original price
$59.50 / 0.85 = $70
To check, we must get the 15% equivalent amount from the original price.
$70 x 15% = $10.50 discount value
$70 - $10.50 = $59.50 discounted price
