Answer:
The answer is 16.8%
Step-by-step explanation:
First, find the difference in the price, which is $78. You can then use that number to find the percentage by dividing the difference by the original price, then moving the decimal over to the right twice. You prove this with the discount equation. $387= $465-(16.8%*465). You will get a number similar to 387, but that is only because you are using a rounded percentage.

Answer:
[tex]y=-2\\[/tex]
Step-by-step explanation:
Use the values of the unit circle to get the (x,y) when Θ=[tex]\frac{11\pi}{6}[/tex], which is [tex](\frac{\sqrt{3}}{2}, -\frac{1}{2})[/tex].
The cosecant (csc) function is the reciprocal of the sine function, so we take the y value and take the reciprocal of it, which is -2.

The line represented by the equation 4y + 2x = 33.6 shares a solution point with the line represented by the table below. The solution for this system is:
Answer:
(6.0)(5.4)
Step-by-step explanation:
First we have to find the equation of the line represented in the table; for that we have to find it's slope and it's y-intercept and then write it in the following form:
The slope of the line we get from first two points:
thus we have
we find by putting the point into the function:
Thus we have
Now we have to find where this line intersects with ; to do this we just substitute with :
We have the x-coordinate of the intersection.
We find the y-coordinate by substituting into :

Answer:
42.5
Step-by-step explanation:
First, you should find the area of the the total figure, this being a rectangle (Two of the four corners are folded over). To do this, you must multiply 9 (the length) by the height of the shape, which is 3.5 + 2 (5.5). Next, you should subtract the area of each triangle that is folded over, the area of the bottom left triangle being 2 and the area of the bottom right triangle being 5. This should bring your answer to an area of 42.5
Hope this helps :)
It is reported that 72% of working women use computers at work.
Choose 5 working women at random. Find
a. The probability that at least 1 doesn't use a computer
at work
b. The probability that all 5 use a computer in their
jobs
Answer:
a
Step-by-step explanation:
the answer is up at the top
The probability that at least 1 doesn't use a computer at work is 0.8065.
The probability that all 5 use a computer in their jobs is 0.1935.
What is a probability function?Suppose we let X represent the no. of women that make use of computers at work. A given random variable X which approaches a binomial distribution with the following data n = 5 and p = 0.72 has a probability function:
[tex]\mathbf{P(X=x) = \left \{ {{(^5_x)(0.72)^x(0.28)^{5-x}, \ X = 0,1,2,...5} \atop {0, \ \ \ \ \ \ \ \ \ \ \ \ elsewhere }} \right.}[/tex]
a.)
Then, the probability that at least 1 doesn't use a computer at work can be computed as:
[tex]\mathbf{1-P(X=5) =1 - (^5_5)(0.72)^5(0.28)^{5-5}}[/tex]
[tex]\mathbf{1-P(X=5) =1 - (0.72)^5}[/tex]
[tex]\mathbf{1-P(X=5) =1 - 0.1935}[/tex]
⇒ 0.8065
b.)
The probability that all 5 make use of computers at their job is;
[tex]\mathbf{P(X=5) = (^5_5) (0.72)^5 (0.28)^{5-5}}[/tex]
[tex]\mathbf{P(X=5) = 1 \times (0.72)^5 \times 1}[/tex]
P(X = 5) = 0.1935

Sonia graphs the equations y = –x2 + 4x and y = x – 4 to solve the equation –x2 + 4x = x – 4. Her graph is shown below.
Answer:
C.–1 and 4
Step-by-step explanation:
Solving the equations y = –x² + 4x and y = x – 4
–x² + 4x = x – 4
x² - 4x + x = 4
x² - 3x = 4
x² - 3x + (3/2)² = 4 + (3/2)²
(x - 3/2)² = 4 + 9/4
= 6.25
x - 3/2 = √6.25 or x - 3/2 = -√6.25
x = 2.5 + 1.5 x = -2.5 + 1.5
= 4 = -1
Answer: C -1 and 4

I don’t know this i need help what’s x?
Answer:
what is the question for the problem.................
Answer:
x = 3
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the secant's external part and the entire secant, that is
8(8 + 2x + 4) = 12²
8(12 + 2x) = 144 ( divide both sides by 8 )
12 + 2x = 18 ( subtract 12 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Consider the glven solids with the dimensions shown. Which solids are similar?
A. only figure 1 and figure 2
B. only figure 1 and figure 3
C. only figure 2 and figure 3
D. all three figures
Answer:
A) only figure 1 and figure 2
Step-by-step explanation:
Answer: Choice A) only figure 1 and figure 2
===========================================================
Explanation:
Let's assume that figure 2 is similar to figure 3.
If this is the case, then the horizontal portions would divide to 30/15 = 2, showing that figure 3 has sides that are twice as long compared to figure 2. But then notice that the vertical sides divide to 36/24 = 1.5, which doesn't match with the previous result of 2.
Figures 2 and 3 cannot be similar for that reason.
Also, figures 1 and 3 are not similar either. Note the horizontal portions divide to 30/10 = 3 while the vertical portions divide to 36/16 = 2.25; the results 3 and 2.25 don't match.
We eliminate answers B, C and D. The only thing left is choice A.
-------------------
To verify choice A is true, we divide each corresponding piece like so
Horizontal: 15/10 = 1.5Vertical: 24/16 = 1.5Slanted: 12/8 = 1.5Each division leads to the same result of 1.5, meaning that figure 2's side lengths are 1.5 times longer than the corresponding side lengths of figure 1. So this confirms that figure 1 is similar to figure 2.

The length of a rectangle is 5 yd less than twice the width, and the area of the rectangle is 33 yd?. Find the dimensions of the rectangle.
Answer:
Step-by-step explanation:
L=2W-5
A=LW, using L from above gives you
A=(2W-5)W
A=2W^2-5W
2W^2-5W-A=0, since A=33yd^2
2W^2-5W-33=0
2W^2+6W-11W-33=0
2W(W+3)-11(W+3)=0
(2W-11)(W+3)=0, since W>0
W=11/2
W=5.5yd, since L=2W-5
L=6yd
So the dimensions are W by L, 5.5yd by 6yd

[tex](x - 7)(x - 5) = 3[/tex]
Answer:
x = 4, x = 8
Step-by-step explanation:
Given
(x - 7)(x - 5) = 3 ← expand factors using FOIL
x² - 12x + 35 = 3 ( subtract 3 from both sides )
x² - 12x + 32 = 0 ← in standard form
(x - 4)(x - 8) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x - 8 = 0 ⇒ x = 8
