Answer:
There is a 33.3% chance you will pull a red marble after pulling a blue one.
Step-by-step explanation:
There are a total of 10 marbles in the sack. A blue marble is removed from the bag without being replaced, leaving 9 in the sack. 3 of the marbles left are red. To find the probability of pulling a red marble, we divide the number of red marbles by the number of total marbles.
3/9 = 1/3 = 0.333 = 33.3%

Given the equation of a circle below, find the diameter of the circle. Use only the digits 0-9 to enter the diameter.
Answer:
10
Step-by-step explanation:
Standard form for a circle is
(x - h)² + (y - k)² = r²
where (h, k) is the center and r is the radius
--------------------------------
x² + y² - 18x + 24y = -200
Rearrange
(x² - 18x) + (y² + 24y) = -200
Complete the square for x
(x - 9)² + (y² + 24y) = -200 + (-9)²
Complete the sqaure for y
(x - 9)² + (y + 12)² = -200 + (-9)² + 12²
(x - 9)² + (y + 12)² = 25
Now the equation is in standard form
r² = 25
r = 5
Therefor Diameter = 10

A property that offers a 7.5 percent return on the listing price has a monthly net of $810.
The property is listed at
Answer:
$129,600
Step-by-step explanation:
Given that
The return percentage is 7.5%
And, the monthly net is $810
We need to find the property listed price
Since we assume that the return percentage is on annual basis
So, for monthly, it is
= 7.5% ÷ 12
= 0.625%
Now the property listed price is
= $810 ÷ 0.625%
= $129,600

During the month of june, jessica volunteers at a library every 6 days and at a veterinarians office every 10 days. jessica’s first visit to the library was on June 6 and her first visit to the veterinarian office was on June 1th.
What day in June will jessica volunteer at both locations?
Anwser Options
june 6
june 10
june 18
june 20
june 24
june 30
The day in June, Jessica volunteered at both locations if she volunteers at the library every 6 days and at a veterinarian's office every 10 days is June 30, so option F is correct.
What is LCM?The abbreviation LCM stands for "Least Common Multiple." The smallest multiple that two or more numbers share is known as the least common multiple.
For instance: The LCM of 2 and 3 is 6.
Given:
Jessica volunteers library every 6 days,
Jessica's veterinarian's office, every 10 days,
So for her visit to both, the place takes the LCM of 6 and 10,
LCM of 6 and 10 = 30,
Hence, on the 30th day, she visits both places so if she starts volunteering from the 1st of June then she will visit both places on the 30th of June.
Therefore, The day in June, Jessica volunteered at both the location if she volunteers at a library every 6 days and at a veterinarian's office every 10 days. Jessica’s first visit to the library was on June 6 and her first visit to the veterinarian's office was on June, 1st is June 30.

[ ? ]%
Step-by-step explanation:
You can solve this using the binomial probability formula.The fact that "obtaining at least two 6s" requires you to include cases where you would get three and four 6s as well.Then, we can set the equation as follows: P(X≥x) = ∑(k=x to n) C(n k) p^k q^(n-k) n=4, x=2, k=2when x=2 (4 2)(1/6)^2(5/6)^4-2 = 0.1157when x=3 (4 3)(1/6)^3(5/6)^4-3 = 0.0154when x=4 (4 4)(1/6)^4(5/6)^4-4 = 0.0008Add them up, and you should get 0.1319 or 13.2% (rounded to the nearest tenth)The angles in this diagram are complementary.

What is the payback period for Project A?
Answer:
3.17 YEARS
Step-by-step explanation:
Payback calculates the amount of time it takes to recover the amount invested in a project from it cumulative cash flows
Payback period = Amount invested / cash flow
Payback period for option A, Product A
Amount invested = –$221,117
Amount recovered in year 1 = –$221,117 + 27,200 = -193,917
Amount recovered in year 2 = -193,917 + 60,000 = -133,917
Amount recovered in year 3 = -133,917 + 60,000 = -73,917
Amount recovered in year 4 = -73,917 + 425,000 = 351,083
Payback period = 3 years + (73,917 / 425,000) = 3.17 years
(-14, 3), (20, -11) slope
Answer:
= -7/ 17
Step-by-step explanation:
To find the slope when given two points
m= ( y2-y1)/(x2-x1)
= ( -11-3)/(20- -14)
= (-11-3)/(20+14)
= -14/34
Divide top and bottom by 2 to simplify
= -7/ 17
Answer:
-7/17
Step-by-step explanation:
Plug these points into the equation y2-y1/x2-x1. In this case, the y2 value is -11 and the y1 value is 3. In this case, the x2 value is 20 and the x1 value is -14. Therefore, the equation is -11-3/20--14. This is equal to -14/20+14 which is equal to -14/34. This is equal to -7/17. Therefore, the slope is -7/17

Answer:
GIVEN :-
Ordered pairs given are :-
(2 , -1)(-5 , 3)(4 , 3)(-2 , -3.5)(0.5 , 1.75)TO FIND :-
Correct quadrant for each ordered pair.FACTS TO KNOW BEFORE SOLVING :-
While writing the co-ordinates of a point , its ordered pair is always in the form of ( x , y ) where x = x-coordinate of the point & y = y-coordinate of the point.In Quadrant 1 , the coordinates of a point is always = ( +x , +y ) because Quadrant 1 lies between the positive side of x-axis & positive side of y-axis.In Quadrant 2 , the coordinates of a point is always = ( -x , +y ) because Quadrant 2 lies between the negative side of x-axis & positive side of y-axis.In Quadrant 3 , the coordinates of a point is always = ( -x , -y ) because Quadrant 3 lies between the negative side of x-axis & negative side of y-axis.In Quadrant 4 , the coordinates of a points is always = ( +x , -y ) because Quadrant 4 lies between the positive side of x-axis & negative side of y-axis.SOLUTION :-
(2 , -1) is in Quadrant 4 because it's x-coordinate is positive whereas its y-coordinate is negative.(-5 , 3) is in Quadrant 2 because its x-coordinate is negative but y-coordinate is positive.(4 , 3) is in Quadrant 1 because both its x-coordinates & y-coordinates are positive.(-2 , -3.5) is in Quadrant 3 because both its x-coordinates & y-coordinates are negative.(0.5 , 1.75) is in Quadrant 1 because both its x-coordinates & y-coordinates are positive.There are 24 students in a class. 8 of the students are boys. Write th amount of the boys in the class as a fraction in its simplest form.
