Answer:
FALSEStep-by-step explanation:
Given the polynomial f(x) divided by x-4
To check whether the remainder will be equal to f(-4), we need to get whether the value of x is -4 if we set x-4 to zero as shown;
x- 4 = 0
Add 4 to both sides
x - 4 + 4 = 0+4
x = 4
Since the value of x is 4 not -4 hence the remainder will NOT be equal to f(-4). The answer is false

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

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

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]

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

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>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.

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).

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

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.

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.
