An office supply company conducted a survey before marketing a new paper shredder designed for home use. In the survey, 80% of people used the shredder were satisfied with it. Because of the high acceptance rate, the company decided to make the new shredder. Assume that 80% of all people who use it will be satisfied. On a certain day 7 customers bought the shredder.
Let x denote the number of customers in this sample of 7 who will be satisfied with this shredder. Using the binomial probabilities table, obtain the probability distribution of x and fill in the table
x 0 1 2 3 4 5 6 7
p(x)(for each number)
Answer:
Probability distribution of x
Step-by-step explanation:
Binomial Probability = N c x . (P)^x . (Q)^ n-x
N = Total trials, 7 customers here ; P = Prob of success, 0.80 satisfied here ; x = No. of success (1....7) ; Q = Prob of fail, 0.20 not satisfied here
P (x = 1) = 7c1 (0.80)^1 (0.20)^7 = 0.00035
P (x = 2) = 7c2 (0.80)^2 (0.20)^6 = 0.0043
P (x = 3) = 7c3 (0.80)^3 (0.20)^5 = 0.0286
P (x = 4) = 7c4 (0.80)^4 (0.20)^4 = 0.1146
P (x = 5) = 7c5 (0.80)^5 (0.20)^3 = 0.2752
P (x = 6) = 7c6 (0.80)^6 (0.20)^2 = 0.3670
P (x = 7) = 7c7 (0.80)^7 (0.20)^1 = 0.2097
Which of the number lines is the correct graph for the inequality x ≥ 9?
Answer:
graph D.
Step-by-step explanation:
The inequality that is being shown in the question means that the value of x is equal to or greater than 9. Greater values are represented as all of the values to the right of a certain number. On a number line "equal to" is represented by a closed circle. Therefore, with this knowledge we can see that out of all of the provided options the only one that follows these set of rules would be graph D.
What’s 4/5 of 3 And what’s 2/9 of 20
Answer:
4/5 of 3 = 12/5
2/9 of 20 = 40/9
Step-by-step explanation:
Answer:
1. 2.4
2. 4.444
Step-by-step explanation:
First, let's look at 4/5 of 3. We can set it up like this:
[tex]3 * \frac{4}{5}[/tex]Next, multiply the 3 by the 4 to get this:
[tex]\frac{12}{5}[/tex]Then, if a calculator is permitted, we get the answer of 2.4.
The next thing to do would be to repeat the steps for 2/9 of 20.
[tex]20 * \frac{2}{9}[/tex]
[tex]\frac{40}{9} = 4.444[/tex]
Hope this helps!!

Your expression is a little unclear, but I am assuming your expression as:
[tex]7+\frac{2x}{4}=5[/tex]
The solution would still clear your concept in anyway.
Answer:
The value of x = -4
Step-by-step explanation:
Given the expression
[tex]7+\frac{2x}{4}=5[/tex]
solving the expression
[tex]7+\frac{2x}{4}=5[/tex]
as 2x/4 = x/2, so
[tex]7+\frac{x}{2}=5[/tex]
subtract 7 from both sides
[tex]7+\frac{x}{2}-7=5-7[/tex]
simplify
[tex]\frac{x}{2}=-2[/tex]
Multiply both sides by 2
[tex]\frac{2x}{2}=2\left(-2\right)[/tex]
simplify
[tex]x=-4[/tex]
Thus, the value of x = -4

Answer:
The conclusion of the scientist should be that the results are statistically significant and that there is a high probability that the mice brains doubled in sizes after watching the videos
Step-by-step explanation:
The complete question is as follows;
A scientist studies the development of brain size in mice, believing that exposure to statistics videos is related to brain development.. After having mice intensively watch statistics videos, the scientist discovers that mice have doubled the size of their brains. After running a statistical test on the difference, the scientist obtained a p-value of .04. What should the scientist conclude, assuming an a=.05?
Solution;
We start by forming the null hypothesis
The null hypothesis H0 here is that;
The mice have not doubled the sizes of their brains after watching the the videos
While the alternative hypothesis H1 is that the mice have double their brain sizes after watching the videos
To know what to conclude, we will need to look at the p-value obtained
The p-value we have here is 0.04 which is less than 0.05 and thus , shows the existence of a strong evidence against the null hypothesis which means we will have to accept the alternative
Hence, the conclusion of the scientist should be that the results are statistically significant and that there is a high probability that the mice brains doubled in sizes after watching the videos

Answer:
The answers are:
2u = <10,2>-3u = <-18,-6>u+v = <11,3>3u-4v = <-9,-5>Step-by-step explanation:
Given vectors are:
u = <5,1>
v = <6,2>
The vectors are given in the form of ordered pairs, the operations can be applied on the coordinates of ordered pairs
Now,
[tex]2u = 2(5,1) = (10,2)[/tex]
[tex]-3v = -3(6,2) = (-18,-6)[/tex]
Now we have to add two vectors
In order to add two vectors, their respective coordinates are added:
So,
[tex]u+v = (5,1) + (6,2)\\= (5+6, 1+2)\\=(11,3)[/tex]
And
[tex]3u-4v = 3(5,1) - 4(6,2)\\= (15,3) - (24,8)\\= (15-24, 3-8)\\=(-9, -5)[/tex]
Hence,
The answers are:
2u = <10,2>-3u = <-18,-6>u+v = <11,3>3u-4v = <-9,-5>I have the answers i just need to know the solution on how you do 10 and 11.
4 glasses of milk and 2 snack bars have a total of 86 carbohydrates (carbs), and
2 glasses of milk and 3 snack bars have a total of 69 carbs. Determine how many carbs are in one glass of milk and in one snack bar.
Answer:
There are 15 carbs in one glass of milk and 13 carbs in one snack bar.
Step-by-step explanation:
Let m be the number of carbohydrates in one glass of milk and
Let s be the number of carbohydrates in one snack bar
Then according to given information
The system of equations will be:
[tex]4m+2s = 86\\2m+3s = 69[/tex]
Multiplying equation 2 by 2 and subtracting from equation 1
[tex]2(2m+3s) = 69*2\\4m+6s = 138[/tex]
Subtracting from equation 1
[tex]4m+2s-(4m+6s) = 86-138\\4m+2s-4m-6s = -52\\-4s = -52\\\frac{-4s}{-4} = \frac{-52}{-4}\\s = 13[/tex]
Putting s=13 in equation 1
[tex]4m+2(13) =86\\4m+26 = 86\\4m = 86-26\\4m = 60\\\frac{4m}{4} = \frac{60}{4}\\m = 15[/tex]
Hence,
There are 15 carbs in one glass of milk and 13 carbs in one snack bar.

Please select the best answer from the choices provided
A: x = 4
B: x = 28
C: x = 8
D: x = 7
32/8=28/x
we multiply by x
x*32/8=28
we multiply by 8/32
x=28*8/32
8 divides by 32
x=28/4=7
D: x = 7
Answer:
D
Step-by-step explanation:
Given
[tex]\frac{32}{8}[/tex] = [tex]\frac{28}{x}[/tex] ( cross- multiply )
32x = 224 ( divide both sides by 32 )
x = 7 → D

Suppose that scores on a particular test are normally distributed with a mean of 110 and a standard deviation of 20. What is the minimum score needed to be in the top 2% of the scores on the test
Answer:
The minimum score needed to be in the top 2% of the scores on the test
is n = 10,00,000
Step-by-step explanation:
Step(i):-
Mean of the Population = 110
Standard deviation of the Population = 20
The estimated error = 2% = 0.02
Step(ii):-
The estimated error is determined by
[tex]E = \frac{S.D}{\sqrt{n} }[/tex]
[tex]0.02 = \frac{20}{\sqrt{n} }[/tex]
⇒ [tex]\sqrt{n} = \frac{20}{0.02} = 1000[/tex]
Squaring on both sides, we get
n = 10,00,000
The minimum score needed to be in the top 2% of the scores on the test
is n = 10,00,000
which ordered pair lies on the graph of the function y= -2x +1
Note: You did not mention the ordered pair choices. So, I am letting you clear your concept about taking some sample ordered pairs which anyways would clear your concept.
Answer:
The ordered pairs (1/2, 0) and (0, 1) are on the graph.
The graph is also attached.
Step-by-step explanation:
Given the function
[tex]y= -2x +1[/tex]
Any ordered pair which may satisfy the equation would lie on the graph.
Let us determine the x and y-intercepts.
Determining the x-intercept
We know that the x-intercept can be determined by setting y=0, and the solving for x. so
[tex]y= -2x +1[/tex]
0 = -2x+1
-2x = -1
Divide both sides by -2
x = 1/2
Thus, the x-intercept is (1/2, 0)
Determining the y-intercept
We know that the y-intercept can be determined by setting x=0, and the solving for y. so
[tex]y= -2x +1[/tex]
y = -2(0)+1
y = 1
Thus, the x-intercept is (0, 1)
Thus, the ordered pairs (1/2, 0) and (0, 1) are on the graph.
The graph is also attached.
The ordered pairs (1/2, 0) and (0, 1) are on the graph.
Let us plug x = 0.
So,
[tex]y=-2x+1\\y=-2(0)+1\\y=1[/tex]
So the point is (0, 1).
Let us plug x = 1/2.
So,
[tex]y=-2x+1\\y=-2\left(\frac{1}{2}\right)+1\\y=-1+1\\y=0[/tex]
So the point is (1/2, 0).

Shareen walked a total of 9.52 miles in a walk-a thon. If her average speed was 2.8 miles per hour, how long did it take Shareen to complete the walk?
Answer:
t = 3.4 hour
Step-by-step explanation:
Distance to be covered by Shareen, d = 9.52 miles
The average speed of Shareen, v = 2.8 mph
We need to find the time taken by Shareen to complete the walk.
The formula for average speed,
v = distance/time
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{9.52}{2.8}\\\\t=3.4\ \text{hour}[/tex]
Hence, it will take 3.4 hour to complete the walk.
