Answer:
A
Step-by-step explanation:
r^2 = (x - k)^2 + (y - h)^2
Work Shown:
(h,k) = (2,-2) is the center. So h = 2 and k = -2
r = 4 is the radius. We go 4 units from the center C to point P
Therefore,
(x-h)^2 + (y-k)^2 = r^2
(x-2)^2 + (y-(-2))^2 = 4^2
(x-2)^2 + (y+2)^2 = 16

There are 130 people in a sport centre. 73 people use the gym. 62 people use the swimming pool. 58 people use the track. 22 people use the gym and the pool. 29 people use the pool and the track. 25 people use the gym and the track. 11 people use all three facilities. A person is selected at random. What is the probability that this person doesn't use any facility
To find : Probability that person doesn't use any facility
Given : Total people = 130 ; People using gym (G), Swimming Pool (S), Track (T) = 73, 62, 58 respectively. People using G & P, P & T, G & T = 22, 29, 25. People using P & G & T = 11
So : Prob (G) = 73/ 130 , Prob (S) = 62/130 , Prob (T) = 58/130
P (G ∩ P) = 22 / 130 , P (P ∩ T) = 29 / 130 , P (G ∩ T) = 25 / 130 , P (P ∩ G ∩ T) = 11 / 130
Prob [ Person uses either P or G or T ] :
P (PUGUT) = P(G) + P (S) + P (T) - P (G ∩ P) - P (P ∩ T) - P (G ∩ T) - 2 P (P∩G∩T) = ( 73 + 62 + 58 - 22 - 29 - 25 - 22) / 130 = 95 / 130
Prob [Person uses neither P or G or T] : 1 - Pr [Person uses either P or G or T] = 1 - P (PUGUT) = 1 - (95 / 130) = 35 / 130
Hence, Probability that person doesn't use any facility = 35 / 130

What is the decimal multiplier to increase by 99%?
Answer:To work out the multiplier, first add or subtract the percentage from 100, then convert to a decimal. Example: we want to add 20% to £110. To work out the multiplier, add 20 to 100, to get 120, and then change it to a decimal (divide by 100) to get 1.2.
Step-by-step explanation:
The decimal multiplier of a number to increase by 99% will be 1.99.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Let's consider the number x.
To increase it by 20% we need to find 20% of it so 0.20x
Now, add this 20% to x so that it will increase by 20% as,
0.20x + x = 1.20x
Thus,to increase the number by 20% we need to multiply 1.20
Similarly to increase a number by 99% we need to multiply with 1.99.
Hence "The decimal multiplier of a number to increase by 99% will be 1.99".

All else being equal, a study with which of the following error ranges would be
the most reliable?
A. +-6 percentage points
B. +-15 percentage points
C. +-9 percentage points
D.+- 112 percentage points
The study with an error range of +-6 percentage points would be the most reliable.
As larger error ranges, such as options B, C, and D, indicate a greater degree of uncertainty and variability in the dat This reduces the reliability and precision of the study's findings.
So, when all other factors are equal, a study with a smaller error range, like with +-6 percentage points, would be considered more reliable.
Thus, with an error range of +-6 percentage points, has the smallest range.

The names of 5 boys and 5 girls are in a hat. What is the probability of first drawing a girl’s name and then a boy’s name from the hat?
Answer:
9/20
Step-by-step explanation:
The probability of drawing a girl's name is 0.5, since there are 5 girls in 10 kids here. If that girl's name is not replaced, then the probability of drawing a boy's name is 5/9, since there are still such names but the total number of names is now 9.
Thus, the probability of this joint event is (0.5)(9/10) = 4.5/10 = 9/20
Answer:
so drawing a girls name from the hat would be 5/10 since 5 girls are there out of 10 students in total. After, you pick the girls name the total number of student names would become 9 and since there are 5 guys, you get a 5/9 probability
Mary is paid 7.5% commission on all of her sales. She had sales of $2300 for the month of December. How much commission did Mary make?
Answer: $172.50
Step-by-step explanation:
$2300 x 0.075 = $172.50
You can double check quickly because you know 10% of 2300 is $230, so 5% is $115. The answer is halfway between the 5% and 10% numbers, so you know it is reasonable.

What is the measure of ∠R?
Answer:
∠ R ≈ 36.9°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos R = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{RT}{RS}[/tex] = [tex]\frac{8}{10}[/tex] , thus
∠ R = [tex]cos^{-1}[/tex] ([tex]\frac{8}{10}[/tex] ) ≈ 36.9° ( to 1 dec. place )

Simply the expression [tex]\frac{x-7}{3} - \frac{5-x}{2}[/tex]
Answer: [tex]\frac{5x-29}{6}[/tex]
Step-by-step explanation:
To simplify the equation, we can just subtract the 2 fractions. First, we need to make sure they have a common denominator.
[tex]\frac{2(x-7)}{6} -\frac{3(5-x)}{6}[/tex]
Now that the fractions have the same denominator, we can distribute the numerator and subtract.
[tex]\frac{2x-14}{6} -\frac{15-3x}{6} =\frac{2x-14-15+3x}{6} =\frac{5x-29}{6}[/tex]
