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%
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%

Answer:
100°
Step-by-step explanation:
all four angles added together total 360°
x = 360° - 60° - 110° - 90°
x = 100°
Explain the difference between center and shape of a data set.
Answer
The center is the median and/or mean of the data. The spread is the range of the data. And, the shape describes the type of graph. The four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform.
Step-by-step explanation:
A circle of radius 10.5cm has a sector whose angle at the centre is cut off. Find the perimeter of the resulting sector.

Mark this and retum
Answer: are perpendicular
Step-by-step explanation:
Two lines intersecting at a right angle are said to be perpendicular. When the lines cross each other, we say the lines have intersected.
The point of intersection of the lines is the pointe where they cross one another. In case the lines never interesct, such lines are refered to as the parallel lines.
Which of the following statements are true? Select all that apply
13- (-9)
explain how you got this answer
16+ only please answer this
Answer:
22
Step-by-step explanation:
double negative is a plus sign
13--9=22
Answer: 22
Step-by-step explanation:
Here, we need to know the concept of changing signs. Under any circumstances, if there is a "-" sign outside of parenthesis, the signs inside need to be the opposite. If you are still not very clear, I can provide some examples below:
1-(+1) ⇒ there is a "-" sign, so we need to convert the sign inside "+" to "-" ⇒ 1-1 ⇒ 02-(-1) ⇒ there is a "-" sign, so we need to convert the sign inside "-" to "+" ⇒ 2+1 ⇒ 3-------------------------------------------------------
Given
13 - (-9)
⇒There is a "-" sign outside
⇒We need to convert the sign inside "-" to "+"
⇒13+9
⇒22

Answer:
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.

Describe and correct the error in writing an equation of the line with a slope of 2 and a y-intercept of 7.
Please don't put any links or I will report you.
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.

Which is a greater angle of rotation? 720° or 6π radians? Explain how you know.
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.

HELP plesse with 9 and 10
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)
Mark runs to catch a ball. Explain how the structure of muscle tissue helps him perform this function
Answer:
Muscles give structure and power for any kind of movement, so the tissue needs to be flexible and tightly packed for movement. The tight bands of tissue shown in the picture allows this movement to occur.
