Option C is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
To complete the square, we add and subtract the square of half of the coefficient of x, i.e., (10/2)² = 25, inside the parentheses:
8(x²+ 10x + 25 - 25) = -5
Simplifying the expression inside the parentheses.
8(x + 5)² = 200
Dividing both sides by 8.
(x + 5)² = 25
Taking the square root of both sides.
x + 5 = ±5
Solving for x.
x = -10 or x = 0
Thus,
The missing number is 25.

Answer:
73,205 vinyls
Step-by-step explanation:
To calculate the number of vinyls sold we need to calculate the compounded increase. To do this we simply raise the number of times that the initial value increases by the number of difference in years from the start to the current year. Then we multiply this number by the initial number of vinyl records. Since there are 4 years between 2012 and 2016, the formula would be the following...
50,000 * [tex]1.1^{4}[/tex] = x
50,000 * 1.4641 = x
73,205 = x
Finally, we can see that there will be a total of 73,205 vinyls in 2016

The mean weight of a domestic house cat is 8.9 pounds with a standard deviation of 1.1 pounds. The distribution of domestic house cat weights can reasonably be approximated by a normal distribution. What proportion of domestic house cats weigh less than 7 pounds?
Answer:
0.0421
Step-by-step explanation:
We solve using the z score formula
z-score is is z = (x-μ)/σ,
where x is the raw score
μ is the population mean = μ = 8.9 pounds
σ is the population standard deviation = σ = 1.1 pounds
For x < 7 pounds
z = 7 - 8.9/1.1
= -1.72727
Probability value from Z-Table:
P(x<7) = 0.042059
Therefore, the proportion of domestic house cats weigh less than 7 pounds is
0.042059
Approximately = 0.0421

Consider two unique parallel lines. What aspects of these two lines are the same? What aspects of these two lines would have to be different?
using the image,find angle x and y
Answer:
x =55 degrees
y = 35 degrees
Step-by-step explanation:
We know that the distance from the center of the circle to the circumference is the radius
that means the triangle starting out from O is isosceles since two of the sides are radii and thus the angle of those sides are the same
Let us call one of the angles z
we know that the sum of the angles in a triangle is 180 degrees
That simply means;
80 + 2z = 180
2z = 180-80
2z = 100
z = 100/2
z = 50 degrees
So the angles at each upper end of the cyclic quadrilateral are;
x + 50 and y + 50
we know that the angles that face each other in a cyclic quadrilateral are supplementary
Thus;
95 + y+ 50 = 180
y= 180-95-50
y= 180-145
y = 35 degrees
Now, for x, the angle supplementary to the angle that faces x+ 50 equals x + 50
Thus;
x + 50 = 105
x= 105-50
x = 55 degrees

Patrick wants to buy a new computer. He already has $275 saved and plans to save $125 each month. The price of the computer is currently $1,850, but Patrick expects the price to drop by $100 each month. Patrick wants to determine the number of months he will need to save.
a) If x represents the number of months, then write an equation to represent A, the total amount Patrick saves.
b)If x represents the number of months, then write an equation to represent C, the cost of the computer.
c)Use your equations from part “a” and part “b” to determine how many months he will need to save before he can buy the computer. Show your work or explain how you got your answer.

Step-by-step explanation:
Start by using the distance formula to find the raidus
The two points are (-2,1) and (-4,1)
√((-4+2)²+(1-1)²)= 2
The radius is two and we have our center which means we can write
(x+2)²+(y-1)²=4
now it's just a matter of expanding everyhting
x²+4x+4+y²-2y-3=0
x²+y²+4x-2y+1=0
This is equal to B
Your company is considering offering 600 employees the opportunity to transfer to its new headquarters in Ottawa and, as personnel manager, you decide that it would be fairest if the transfer offers are decided by means of a lottery. Assuming that your company currently employs 200 managers, 300 factory workers, and 900 miscellaneous staff, find the following probabilities, leaving the answers as formulas.
(a) All the managers will be offered the opportunity.
C(___,___)
C(___,___)
(b) You will be offered the opportunity.
C(___,___)
C(___,___)
Answer:
Probability of 100 managers being selected= 100C100*1100C800/1200C900
Probability of selecting just one manager = 1C100*1199C899/1200C900
Explanation:
Given 100 managers, 200 factory workers, 900 miscellaneous workers, and workers bring transferred 900
To find probability of 100 managers leaving given that probability = number of favorable outcomes/total number of outcomes
We use combination since order doesn't matter:
Combination formula= n!/r!(n-r)! Where n= total number of outcomes and r is number of outcome at one time and ! is factorial
Probability of 100 managers using nCr formula for each item = 100C100*1100C800/1200C900
Probability of 1 manager also applying nCr formula as above =1C100*1199C899/1200C900
The probability is the ratio of the favorable event to the total number of events. The probabilities are as follows;
a. P = ¹⁰⁰C₁₀₀ × ¹¹⁰⁰C₈₀₀ / ¹²⁰⁰C₉₀₀
b. P = ¹⁰⁰C₁ × ¹¹⁹⁹C₈₉₉ / ¹²⁰⁰C₉₀₀
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

Assuming that your company currently employs 100 managers, 300 factory workers, and 900 miscellaneous staff.
We can use combination since order does not matter;

Round your answer to one decimal digit. The volume of a cylinder is 1 800 cm3. If the height of the cylinder is 40 cm then the diameter of the cylinder is
Answer:
7.57 cm
Step-by-step explanation:
Volume of a cylinder = πr²h
π = 3.14
r= radius
h = height
1,800 = 3.14 x r² x 40
r² = 1800 /(3.14 x 40)
r² = 14.33121
√14.33121 = r
r = 3.785658 cm
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
Diameter = 2 x 3.785658 cm = 7.57cm
