it would be D, right? A, says that everyday they have to pay $0.25 for all 3 books. C, is saying that for 3 books it costs $1 everyday. B, says that everyday they have to pay $0.50 for 3 books. But D, is saying that you have to pay $0.75 everyday for 3 books. $0.25 * 3 = $0.75. That is why I think it’s D.

Certain drug is used to treat asthma in a clinical trial of the drug 24 of 282 treated subject experienced headaches based on the data from the manufacturer the accompany calculator display results from a test of the claim that less than 11%
Answer:
See below
Step-by-step explanation:
The test is one-tailed (left-tailed in this case) because you are trying to prove that the true proportion is less than the proposed proportion of 11%
The test statistic, z, is given to us as z=-1.34 when rounded to 2 decimal places.
The p-value, p, is given to us as p=0.0908 when rounded to 4 decimal places.
The null hypothesis is [tex]H_o:p<0.11[/tex] because the original claim was that the proportion was less than 11%.
Hope this helped! It's been a while since I've done Statistics, but I believe this is all correct.

9(8-x) =3x
Answer:
x=6
Step-by-step explanation:
I don't know if you are solving for x but x=6
9(8 - x) = 3x
Multiply 9x8 and 9-x
72 - 9x = 3x
Add the 9x
72 = 3x + 9x
Add 3x+9x
72 = 12x
Divide 12x/12 and 72/12
12x/12 = 72/12
x = 6
Answer:
9(8 - x) - 3x
⇛72 - 9x - 3x
⇛72 - 12x
⇛12x = 72
⇛x = 72/12
Therefore, x = 6. Ans.

The table above gives population and employment numbers for a hypothetical country. What is the unemployment rate in this country? Round your answer to the nearest whole percent if necessary
WHAT IS THE ANSWER HELP lol
Answer:B. 17%
A.83%
B.17%
C.20%
D.10%
The unemployment rate in this hypothetical country is equal to 17%.
How to calculate unmployment rate.First of all, we would determine the percentage of people that are employed and then subtract this percentage from the total percentage of 100%.
The table below gives the complete information about the population and employment numbers for a hypothetical country:
Total population = 1,000Total population over 16 years of age = 800Total labor force = 600Total employment = 500Mathematically, employment rate can be calculated by using this formula:
[tex]Employment\;rate = \frac{Employed}{Labor\;force} \times 100\\\\Employment\;rate =\frac{500}{600} \times 100\\\\[/tex]
Employment rate = 83.3 ≈ 83%.
For the unemployment rate, we have:
Unemployment rate = 100 - 83
Unemployment rate = 17%.

What is an equation of the line that passes through the point (-7,-6)(−7,−6) and is parallel to the line x-y=7x−y=7?
Answer:
y = x + 1
Step-by-step explanation:
The gradient of a line can be defined by the equation:
m (gradient) = (y1 – y2 ) ÷ (x1 – x2) ----> "1" and "2" should be in subscript
For (-7,-6) we use x2 and y2 (because this point can be anywhere along a line):
x2 = -7, y2 = -6
Plug these values into the formula above:
m = (y-(-6)) ÷ (x-(-7))
m = (y+6) ÷ (x+7)
At this stage, the equation can't be solved as there are two unknowns. Therefore, the gradient must be found another way. Two lines are parallel if they have the same gradient - in their y=mx+c equations, m will be equal.
x - y=7 is the line alluded to in the question. Rearranging this equation into the line equation format gives:
y = x-7 ---> The gradient (coefficient of x) is 1.
Therefore, the gradient of the other parallel line must also be 1.
This can be substituted into the previous equation to give:
1 = (y+6)÷(x+7)
x+7 = y+6
x+1 = y
Therefore, the answer is y=x+1

How do I factor an equation in the Ax^2+Bx+C form, if A= 2, B= 15, and C= -27. I tried using the x method but I don't think it's the right way.
Answer:
(2x - 3)(x + 9)
Step-by-step explanation:
A = 2
B = 15
C = -27
when we plug these numbers into the equation (Ax^2 + Bx + C) we get
2x^2 + 15x - 27
using the "X" method we have to multiply the A term and C term together
so -27 x 2 = -54
so we have to find factors of -54 that also add to the middle term, 15
- 3 and 18 add to 15 but also multiply to -54 so we can add these numbers into the X (refer to drawing)
A store sells two sizes of bottled water. Size A is 32 fluid ounces (f1 oz) for $2.56 and Size X is $4.80 for
48 fluid ounces. Which is the better buy? Justify your answer.
#size A
32fluid ounces=$2.561 fluid ounce:-
[tex]\\ \sf\longmapsto \dfrac{2.56}{32}=0.08[/tex]
#Size X
48 fluid ounces=4.80$1 fluid ounce
[tex]\\ \sf\longmapsto \dfrac{4.80}{48}=0.1[/tex]
We can see
0.08<0.1
So Size X is better to buyy=varies directly as x, if y=22 when x=-11, find x when y=88
Answer:
x=-44
Step-by-step explanation:
y=22 x=-11
y=88 x=?
y/x=22/-11=-2
88/x=-2
-2x=88
x=-44
find a series expansion for pi using the Maclaurin expansion for arctan(x) and the fact that tan(pi/4)
Recall that for |x| < 1, we have
[tex]\displaystyle \frac1{1-x} = \sum_{k=0}^\infty x^k[/tex]
It follows that, for |-x²| = |x|² < 1, or just |x| < 1,
[tex]\displaystyle \frac1{1+x^2} = \frac1{1-(-x^2)} = \sum_{k=0}^\infty (-x^2)^k = \sum_{k=0}^\infty (-1)^k x^{2k}[/tex]
Taking the antiderivative of both sides gives us
[tex]\displaystyle \arctan(x) = C + \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} x^{2k+1}[/tex]
where C is a constant, which we determine to be 0, since taking x = 0 on both sides makes the series vanish, while arctan(0) = 0 since 0 = tan(0). So
[tex]\displaystyle \arctan(x) = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} x^{2k+1}[/tex]
Since tan(π/4) = 1, it follows that π/4 = arctan(1), so in the series we replace x = 1, then solve for π :
[tex]\displaystyle \arctan(1) = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1} 1^{2k+1}[/tex]
[tex]\displaystyle \frac\pi4 = \sum_{k=0}^\infty \frac{(-1)^k}{2k+1}[/tex]
[tex]\displaystyle \pi = \sum_{k=0}^\infty \frac{4(-1)^k}{2k+1}[/tex]
[tex]\pi = 4 - \dfrac43 + \dfrac45 - \dfrac47 +\cdots[/tex]

Thereisalinethatincludesthepoint(0, 19)andhasaslopeof 10/9 . What isitsequationin slope-intercept form?
Answer: y=(10/9)x+19
Step-by-step explanation:
The slope intercept form is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).
We are given the slope, m:
y=(10/9)x+b
To find b, enter the given point (0,19) and solve for b:
y=(10/9)x+b
19=(10/9)*(0)+b
b = 19
So we have y=(10/9)x+19
how to solve 2(10 -6x)=x -8x
Answer:
x=4
Step-by-step explanation:
2(10 -6x)=x -8x
Multiply 2*10 and 2*-6x
20-12x=x-8x
Add 12x
20=x-8x+2x
Combine x and -8x
20=-7x+12x
Combine -7x and 12x
20=5x
Divide 5x/5 and 20/5
4=x
So x=4
The solution to the equation is x = -4.
To solve the equation 2(10 - 6x) = x - 8x, you can follow these steps:
1. Distribute the 2 to the terms inside the parentheses:
20 - 12x = x - 8x
2. Simplify the expressions on each side by combining like terms:
20 - 12x = -7x
3. Move all the x terms to one side and the constant terms to the other side by adding or subtracting:
-12x + 7x = 20
Simplifying further, we have:
-5x = 20
4. Divide both sides of the equation by -5 to solve for x:
x = 20 / -5
x = -4
Therefore, the solution to the equation is x = -4.
