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
Answers
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.

Answer:
volume of cone is 1÷3πr×r h
Step-by-step explanation:
when we put value in this formula then 1÷3×22÷7×6×6×6 then answer will 72πm×m×m hence it will option B
The volume of a cone diameter of 12 m and a height of 6m is 72π cubics meter. So, option B is correct.
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.
r = 6m
h = 6m
The volume of the cone = 1/3πr^2 h
= 1/3×π×6×6×6
= 72π
Thus, the volume of a cone diameter of 12 m and a height of 6m is 72π cubics meter.

Solve the system by substitution
2y-2x=8;x+y=14
Answers
Solve for the first variable in one of the equations, then subsitute the result into the other equation.
Point Form: (5, 9)
Equation Form: x = 5, y = 9
Simplifying
2y + -2x = 8
Reorder the terms:
-2x + 2y = 8
Solving
-2x + 2y = 8
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
-2x + 2y + -2y = 8 + -2y
Combine like terms: 2y + -2y = 0
-2x + 0 = 8 + -2y
-2x = 8 + -2y
Divide each side by '-2'.
x = -4 + y
Simplifying
x = -4 + y
___________________________________
Simplifying
x + y = 14
Solving
x + y = 14
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1y' to each side of the equation.
x + y + -1y = 14 + -1y
Combine like terms: y + -1y = 0
x + 0 = 14 + -1y
x = 14 + -1y
Simplifying
x = 14 + -1y

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.
Answers
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.

A robot can complete 4 tasks in 5/6 hour. Each task takes the same amount of time. a. How long does it take the robot to complete one task? b. How many tasks can the robot complete in one hour? a. It takes the robot nothing hour(s) to complete one task.
Answers
Here's what we know:
4t = 7/10 (4 tasks take 7/10 of an hour)
Divide both sides by 4:
4t / 4 = 7/10 / 4
t = 7/40
So each task is 7/40 of an hour
7/40 n = 1 (Now we want to find the number of tasks completed in 1 hour)
Multiply both sides by 40/7:
n = 40/7
Converting improper fraction to a mixed number:
n = 5 5/7
So the robot will complete 5 5/7 tasks in an hour. If the answer is looking for fully finished tasks and not partially done ones, the you need to round down to 5.
We know that a robot can complete 4 tasks in [tex]\frac{5}{6}[/tex] hour. Each task takes the same amount of time
What we need to knowWe need to know how long it takes the robot to complete one task
Show your work[tex]\frac{5}{6}[/tex] of an hour is also equal to 50 minutes.
So now, we divide:
50 ÷ 4 = 12.5
Check your workOne thing we can do to check our work is to multiply:
12.5 x 4 = 50
Answerit takes the robot 12.5 minutes to complete one task
Part BWhat we know (same as Part A)We know that a robot can complete 4 tasks in [tex]\frac{5}{6}[/tex] hour. Each task takes the same amount of time
What we need to knowWe need to know how many tasks the robot complete in one hour.
Show your workUsing the information from Part A, we know that [tex]\frac{5}{6}[/tex] is 50 minutes. We also know it take the robot 12.5 minutes to complete one task. 60 minutes is equal to one hour. So what we would do is divide:
60 ÷ 12.5 = 4.80
The robot cannot complete 5 tasks in one hour.
Check your workTo check our work, we can multiply:
4.80 x 12.50 = 60 or one hour
AnswerThe robot can complete 4.8 tasks in one hour.
