Answer:
80%
Step-by-step explanation:
If there are 400 people total and 80 of them have coupons, then 320 people don’t have coupons. Divide 320 by 400 and you will get 0.8, which is 80%.
The required percentage of the customers not using coupon is 80%.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
Given that,
The total number of customers is 400.
And, those using coupon are 80.
Then, number of customers not using coupon are 400 - 80 = 320
Thus, the percentage of the customers not using coupon is given as,
320/400 × 100
= 8/10 × 100
= 80%
Hence, percent of the customers do not use a coupon is 80%.

There are 8 marbles in a jar. One of the marbles is clear. What is the decimal expansion of 1/8? please help me
Answer:
Step-by-step explanation: 1/8 = .125
move two decimals to right = 12.5
The decimal expansion of 1/8 is 0.125, which is also the probability of drawing a clear marble from a jar of eight marbles, if only one of those marbles is clear.
Explanation:The question asks for the decimal expansion of 1/8. To determine the decimal expansion of the fraction, you simply divide the numerator (the top number, which in this case is 1) by the denominator (the bottom number, which in this case is 8). When performed, 1 divided by 8 results in the decimal 0.125. This concept is similar to calculating probabilities in which the total number of outcomes is divided by the desired outcome. For example, in the case of the marbles in a jar, if one is clear and there are eight total, the probability of drawing a clear marble is also 1/8 or 0.125.

Formula
Area of the circle = πr²
So,
Area = [tex]\frac{22}{7} X8^{2}[/tex] sq cm
= 201.14 sq cm = 201.1 sq cm
Hence,
The area of the circle is 201.1 sq cm.
p(2) = 14 and p(-3) = 0. Write one factor of p(x) and explain how you know
Answer:
Step-by-step explanation:
Given p(2) = 14 and p(-3) = 0, according to factor theorem, if a polynomial p(x) is divided by a function x+c where c is a constant, then x+c is said to be a factor of p(x) if p(-c) = 0 i.e if the remainder is zero after the division.
According to the question, it can be seen that p(-3) = 0. This means that the function x+3 is said to be factor if the remainder of the polynomial is zero when divided the polynomial because the reminder leaves zero after division where c = 3
How many triangles can you construct with the angle measures of 50, 70, and 100?
Answer:
0
Step-by-step explanation:
You can't construct any triangles with those angles. Because when you add all the angles of a triangle, it has to add up to 180. But when we add 50,70, and 100, it equals 220. So you can't construct any triangles.

How do you set up this equation ?
Given:
Quadrilateral PQRS is a rhombus.
To find:
The value of y.
Solution:
In the rhombus PQRS,
PS = 10y and SR = y + 45
Property of rhombus:
All sides are congruent.
⇒ PS = SR
⇒ 10y = y + 45
Subtract y from both sides.
⇒ 10y - y = y + 45 - y
⇒ 9y = 45
Divide by 9 on both sides.
[tex]$\Rightarrow \frac{9y}{9} =\frac{45}{9}[/tex]
⇒ y = 5
The value of y is 5.

Which statement best describes the association between variable X and variable Y?
moderate positive association
perfect positive association
moderate negative association
perfect negative association
The correct answer is the fourth option.
Given is a scatter graph with points marked on the graph. The x axis shows the dependent variable and y axis the independent variable
From the graph we see that there seems to be a linear relationship but not fully perfect. Because so many points deviate from the line we can only say that there is a moderate association.
Whenever x increases y increases also the linear regression line of fit has a positive scope.
Hence there is a positive association between variable x and variable Y.

Select the ordered pairs that satisfy the equation y=1/3x
Check all that apply
A. (4,6)
B. (6,2)
C. (3,6)
D. (15,5)
E. (-3,-1)
F (1,3)
Answer:
B, D, E
Step-by-step explanation:
I am assuming that the equation is y = [tex]\frac{1}{3}[/tex] * x and not y = [tex]\frac{1}{3x}[/tex].
Using y = (1/3)x, we can transpose the x, so that now we have y/x = 1/3.
Take note that the given options are in the format of (x, y). You can simply plug all the values, and whichever gave you a result of 1/3 is your answer.
B.) 2/6 = 1/3
D.) 5/15 = 1/3
E.) -1/-3 = 1/3
The ordered pairs that satisfy the equation y = 1/3x are B (6,2), D (15,5), and E (-3,-1). Ordered pairs are verified by substituting the x-value into the equation to see if the resulting y-value matches the pair.
Explanation:To determine which ordered pairs satisfy the given linear equation y = 1/3x, we need to substitute the x-value of each ordered pair into the equation to see if the corresponding y-value is correct.
For pair A (4, 6), substitute x = 4 into the equation to see if y equals 6: 1/3 * 4 = 4/3 which does not equal 6, so A does not satisfy the equation.For pair B (6, 2), substitute x = 6: 1/3 * 6 = 6/3 which equals 2, so B does satisfy the equation.For pair C (3, 6), substitute x = 3: 1/3 * 3 = 3/3 which equals 1, not 6, so C does not satisfy the equation.For pair D (15, 5), substitute x = 15: 1/3 * 15 = 15/3 which equals 5, so D does satisfy the equation.For pair E (-3, -1), substitute x = -3: 1/3 * -3 = -3/3 which equals -1, so E does satisfy the equation.For pair F (1, 3), substitute x = 1: 1/3 * 1 = 1/3, which does not equal 3, so F does not satisfy the equation.So the ordered pairs that satisfy the equation y = 1/3x are B (6,2), D (15,5), and E (-3,-1).

Rewrite the quadratic equation 2x squared plus 12x plus 1 equal y
Answer:16x+1 = y
Step-by-step explanation:
2x squared is basically 2x times 2x which is 4x. So now that you eliminated that you have 4x+12x+1 = y . Now you have to group like terms. 4x+12x= 16x. So now you have 16+1 = y.

1. What If? If Alex had saved $333.34 a month for 3 months, how
much money would he have? If he had used his savings instead
of his credit card, how much less would his purchases have cost him?
2. How much less did Barry's loan, at an interest rate of 9%, cost than
Alex's loan at 21%?
Alex would have saved $1,000.02 over 3 months. The cost of purchases would have been less if he used his savings instead of a credit card because of no interest rates applied. Barry's loan is $120 less expensive than Alex's loan
Explanation:If Alex had saved $333.34 a month for 3 months, he would have saved $333.34 x 3 = $1,000.02. As for the cost of purchases using savings instead of a credit card, we can't directly answer that without knowing the associated credit card interest rate & the time duration. In general, using a credit card would have cost more due to the interest applied to the unpaid balance.
For the second part of your question related to loans, let's assume both Alex and Barry took out loans of $1,000 each for one year. Alex's loan, with an interest rate of 21%, would cost him $1000 x 21/100 = $210 in interest. Barry's loan, at an interest rate of 9%, would cost him $1000 x 9/100 = $90 in interest. Therefore, Barry's loan costs $210 - $90 = $120 less than Alex's loan.

Answer:
18 degrees.
Step-by-step explanation:
115-97=18
The calculated measure of the angle MRN is 18 degrees
Calculating the measure of Angle MRN?From the question, we have the following parameters that can be used in our computation:
Triangle = MNR
Angle N = 97 degrees
From the attached figure
Segment NM is an extension from the exterior angle of M
By the sum of opposite interior angles of triangle, we have
MRN + ∠N = 115 degrees
This means that
MRN + 97 = 115 degrees
Subtract 97 from both sides
MRN = 18 degrees
Hence, the measure of the angle MRN is 18 degrees

Find the value of x. The diagram is not to scale. Explain your reasoning.
Answer:
x = 24
Step-by-step explanation:
Since SR = ST then Δ RST is isosceles, thus the base angles are congruent.
∠ SRT = ∠ STR = 4x - 60
∠ STR and ∠ STU are adjacent and supplementary, thus
∠ STR + ∠ STU = 180, substitute values
4x - 60 + 6x = 180, that is
10x - 60 = 180 ( add 60 to both sides )
10x = 240 ( divide both sides by 10 )
x = 24

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The given equation is:
-2(bx - 5) = 16
To solve for x in terms of b, we need to isolate x on one side of the equation. We can start by distributing the -2 on the left-hand side:
-2bx + 10 = 16
Next, we can subtract 10 from both sides:
-2bx = 6
Finally, we can divide both sides by -2b to solve for x:
x = -3/b
So the value of x in terms of b is -3/b.
To find the value of x when b is 3, we can substitute b = 3 into the equation we just found:
x = -3/b = -3/3 = -1
Hence , the equation is solved and when b is 3, the value of x is -1.
