Seventy-five percent of consumers prefer to purchase electronics online. You randomly select 8 consumers. Find the probability that the number of consumers who prefer to
purchase electronics online is (a) exactly five, (b) more than five, and (c) at most five.
(a) Find the probability that the number that prefer to purchase electronics online is exactly five.
P(5)=
(Round to three decimal places as needed.)
Using the binomial probability relation, the probability of the following events are :
P(x = 5) = 0.2076P(x > 5) = 0.6785P(x ≤ 5) = 0.3215Using the relation :
P(x = x) = nCx * p^x * q^(n-x)
Probability of success, p = 0.75q = 1 - p = 1 - 0.75 = 0.25Number of trials, n = 8Probability of exactly 5 :
P(x = 5) = 8C5 × 0.75^5 × 0.25^3
P(x = 5) = 0.2076
2.) Probability of selecting more than 5 :
P(x > 5) = p(6) + p(7) + p(8)
Using a binomial probability calculator :
P(x > 5) = 0.6785
3.)
Probability at most 5 :
P(x ≤ 5) = p(0) + p(1) + p(2) + p(3) + p(4) + p(5)
Using a binomial probability calculator :
P(x ≤ 5) = 0.3215
Therefore, the probability of selecting at most 5 is 0.3215

A list of numbers is made with the pattern: Start with 3, and multiply by 2 each time.
Here is the beginning of the list of numbers: 3, 6, 12, . . .
Explain how you could use "fill down" in a spreadsheet to find the tenth number in this list.
Step-by-step explanation:
A1 3
A2 =A1*2
this A2 cell we just fill down at least to the 10th line to A10.
A10 then will display the 10th number of the list.
overall, we can see that the 10th number must be
3×2⁹
as the first number is just a constant (the starting value), and each of all the other 9 numbers are multiplying by 2.

Step-by-step explanation:
What does the slope represent in this graph ?
line l contains points (-2,4) and (1,-9). Point P has coordinates (14,-6) answer
We are given a line and a point, I assume that we want to see if the point is on the line or not.
We will see that the point does not belong to the line.
First, let's find the equation of the line.
A general line can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through points (x₁, y₁) and (x₂, y₂), then the slope can be computed as:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Here we know that our line passes through the points (-2, 4) and (1, -9). Then the slope is:
[tex]a = \frac{4 - (-9)}{-2 - 1} = \frac{13}{-3} = -\frac{13}{3}[/tex]
Then our line is something like:
[tex]y = -\frac{13}{3} *x + b[/tex]
To find the value of b, we can use one of the two points that we know that are on the line.
For example, the point (-2, 4) means that when x = -2, we must have y = 4.
Replacing that in the equation we get:
[tex]4 = -\frac{13}{3} *(-2) + b\\\\4 = \frac{26}{3} + b\\\\4 - \frac{26}{3} = b\\\\\frac{-14}{3} = b[/tex]
Now we can write the line equation as:
[tex]y = -\frac{13}{3} *x - \frac{14}{3}[/tex]
Now we need to see if the point (14, -6) belongs to the line.
To see this, we evaluate the line in x = 14.
[tex]y = -\frac{13}{3} *14 - \frac{14}{3} = -\frac{196}{3}[/tex]
This is different than -6, so the point does not belong to the line.

The table shows how much money Diego has after buying some games and represents a linear function.
What is the y-intercept of the function shown in the table, and what does it represent
A. The y-intercept is (4,0), and the 4 represents the amount of money
Diego spends per game.
B. The y-intercept is (4,0), and the 4 represents the number of games
Diego buys.
C. The y-intercept is (0, 150). Diego has $150 before buying any
games.
D. The y-intercept is (0, 150). Diego spends $150 per game.
Answer:
C. The y-intercept is (0, 150). Diego has $150 before buying any
Step-by-step explanation:
Brainlylist
The correct statement is The y-intercept is (0, 150). Diego has $150 before buying any games.
what is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
(0, 150) and ( 1, 112.50)
Now, slope= (112.50-150)/1
slope= -37.5
So, the equation of line is
y- 150= -37.5( x- 0)
y= -37.5x+ 150
Hence, The y-intercept is (0, 150). Diego has $150 before buying any
games.

Answer:
Because 20% of $10 will not be the same as 20% of a larger number
Step-by-step explanation:
120% of 10= 1.2(10)=$12
So we added $2 on the mark up.
Marking 20% off of $12 means the price will be 80% of 12= .8(12)= $9.60
This was a reduction of $2.40 which is 20% of $12
Answer:
Step-by-step explanation:
20% of 10 is $2
Marked up: 10+2 = $12
Marked down: 20% of 12 is 2.40 = 12-2.40 = $ 9.60
20% of 10 is not the same as 20% of 12.

How would I find the values of x and y?
Answer:
3x+1 = 5y+9=61
Step-by-step explanation:
All three of these angles are equal to each other as the figure is a pair of parallel lines with a line through the middle. This means that the angles opposite to each other are equal, thus 61 = 3x + 1. 5y+9 = 61 from the same definition as the lines are parallel. We can also find that it's equal to 61 as 180=119+5y+9.
Thus, x = 20 and y = 52/5
Write an equation in slope intercept form that contains the points (-6,3) and
(-2,1)..
Answer:
y= (-1/2)x+1
Step-by-step explanation:
The general equation of a line in the slope intercept form is y= mx+b, where
m = the slope, and b = y-intercept (where the line crosses the y-axis)
for points (x1 = -6, y1 = 3) and (x2 = -2, y2 = 1)
m= (y2-y1)/ (x2-x1) = (1 - 3)/ (-2 - -6) = -2 / 4 = -1/2
the equation is now y= (-1/2)x+b
substitute the x and y coordinates of any of the points in the equation
for point (-2, 1) we will have 1 = (-1/2)(-2)+b, so b=1
The equation in slope intercept form that contains the points (-6,3) and
(-2,1) is y = (-1/2)x+1

If 1/3 is equivalent to 33 1/3%, what percent is equivalent to 2/3?
A: 33 2/3%
B: 150%
C: 66 2/3%
D: 65%
Answer:
C 66 2/3%
Step-by-step explanation:
1/3 = 33 1/3%
1/3 = 33 1/3 ∙ 1/100 % means 1/100
1/3 = 100/3 ∙ 1/100 33 1/3= (33∙3+1)/3=100/3
1/3 = 100/300 Reduce
1/3 = 1/3 Check so
1/3 = 33 1/3%
Now 2/3=?%
We know that 2/( 3) = N ∙ 1/100 meaning of percent (%)
2/3 = N/100
200 = 3N
200/3 = N
66.66 =N
Therefore 2/3 = 66 2/3 %
