Two lines intersecting at a right angle are said to be perpendicular. When the lines cross each other, we say the lines have intersected.

Surgery Satisfaction Survey
Surgery Satisfied Dissatisfied Total
Knee 70 25 95
Hip 90
15 105
Total 160 40 200
The table shows survey results for 200 patients who had either hip or knee surgery. If one person is selected randomly, what is the
probability he or she was dissatisfied, given that he or she had hip surgery? (Round to the nearest tenth of a percent.)
A)
44.2%
B)
38.6%
0
21.7%
D)
14.3%
Answers
Answer: D) 14.3%
Step-by-step explanation:
Conditional probability formula:
[tex]P(B |\text{given that A}) =\dfrac{P(A\ and\ B)}{P(A)}[/tex]
So, The probability he or she was dissatisfied, given that he or she had hip surgery = [tex]\dfrac{\text{Number of persons are dissatisfied and has hip surgery}}{\text{Total persons have hip surgery}}[/tex]
From the table, the number of persons who are dissatisfied and has hip surgery = 15
Total persons have hip surgery = 105
Required probability = [tex]\dfrac{15}{105}\approx0.143[/tex]
In percent, Required probability = 14.3%
Correct option D) 14.3%

HELP plesse with 9 and 10
Answers
Answer:
Find the solutions below
Step-by-step explanation:
Given the equation
y = -x^2 + 2x + 7
y = -2x+2
Equating both expressions
-x^2 + 2x + 7 = -2x + 2
-x^2 + 2x + 7 + 2x - 2 = 0
-x^2 + 4x + 5 = 0
Multiply through by -1
x^2 - 4x - 5 = 0
Factorize
x^2 - 5x + x - 5 = 0
x(x-5)+1(x-5) = 0
(x+1)(x-5) = 0
x+1 = 0 and x - 5 = 0
x = -1 and 5
when x = -1
y = -2x+2
y = -2(-1)+2
y = 2+2
y = 4
when x = 5
y = -2(5)+2
y = -10+2
y = -8
Hence the solutions are (-1, 4) and (5, -8)
b) y = x^2-3x-27
y = x - 6
Equating both expressions
x^2-3x-27 = x - 6
x^2-3x-27 - x + 6 = 0
x^2-4x-21 = 0
x^2 - 7x + 3x - 21 = 0
x(x-7)+3(x-7) = 0
(x+3)(x-7) = 0
x = -3 and 7
when x = -3
y = -3-6
y = -9
when x = 7
y = 7 - 6
y = 1
Hence the required solutions are (-3, -9) and (7, 1)

Which is a greater angle of rotation? 720° or 6π radians? Explain how you know.
Answers
Answer: the angle would be much greater because the angle calculated up to over 12 radians
Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf 6 \pi \ radians}}[/tex]
Step-by-step explanation:
It's hard to compare degrees and radians, so we should convert, then compare.
To convert radians to degrees, we multiply by 180 over pi. This way, the pi will cancel out when dividing.
[tex]radian * \frac {180}{\pi}[/tex]
[tex]6 \pi * \frac {180}{\pi}[/tex]
[tex]\frac {1080 \pi}{\pi} \\[/tex]
[tex]1080[/tex]
6π radians is equal to 1080 degrees, which is much larger than 720 degrees, so it is the greater angle of rotation.

Answers
Answer:
The mistake they made was they switched the slope and y-intercept.
The correct answer is y=2x+7 because when we write an equation in slope intercept form (y=mx+b) you replace m with the slope and b with the y-intercept.

Equation B, 10 + 5.50n = y.
Step-by-step explanation:
N is the pounds of shrimp that were purchased. This has no set value, it can change at any time.
Since each pound of shrimp is $5.50, if you wanted to buy 10 pounds of fish you'd pay $55.
If I wanted to write an equation to find the total amount of money that I'd need to pay for n pounds of shrimp, I would use the equation 5.50n. (I don't know if this makes sense lol I'm terrible at explaining ;-;)
Now, it states that he wants an extra 10 dollars to pay for expenses. On top of the 5.50n, he wants an extra $10.
You need to add 10 to 5.50, in order to get the total amount, or y.
The final equation is going to be 5.50n + 10 = y, or choice B.
