P(the recipient is male)= 40.5%
p(the degree is a bachelors) = 52%
p(the recipient is female, given that the degree is advanced) = 56.2%
p( the degree is not an associates, given that the recipient is male) = 78.4%
What are the probabilities?Probability determines the chances that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
P(the recipient is male) = total number of males / total number of recipients
1136/2803 = 40.5%
p(the degree is a bachelors) = total number of bachelors degree / total number of degree
= 1456 / 2803 = 52%
p(the recipient is female, given that the degree is advanced) = total number of females with advanced degree / total number of advanced dgree
376 / 669 = 56.2%
p( the degree is not an associates, given that the recipient is male) = number of males that that have degrees other than associates / total number of males
891 / 1136 = 78.4%

A) find the value of x
B) find the value of y
Answer:
a) x = 9.
b) y = 61.
Step-by-step explanation:
As the 2 weighing scales balance:
4 + 4x = 31 + x
3x = 31 - 4 = 27
x = 9.
Also 4 + 4x + x + 31 = y + 2x + 1
Substituting for x:
4 + 4(9) + 9 + 31 = y + 2(9) + 1
80 = y + 19
y = 80 - 19 = 61.
Answer:
x = 9
y = 61
Step-by-step explanation:
The main scales are balanced.
The left side of the main scales comprises another scale, which is also balanced.
From this and the values given, we can construct two equations.
Equation 1
Balancing the scales on the left of the main scales:
⇒ 4 + 4x = 31 + x
Solving this for x:
⇒ 4 + 4x - 4 = 31 + x - 4
⇒ 4x = 27 + x
⇒ 4x - x = 27 + x - x
⇒ 3x = 27
⇒ 3x ÷ 3 = 27 ÷ 3
⇒ x = 9
Equation 2
Balancing the main scales:
4 + 4x + 31 + x = y + 1 + 2x
Rearranging to make y the subject:
⇒ 5x + 35 = y + 1 + 2x
⇒ 5x + 35 - 1 = y + 1 + 2x - 1
⇒ 5x + 34 = y + 2x
⇒ 5x + 34 - 2x = y + 2x - 2x
⇒ 3x + 34 = y
Substituting the found value of x (from Equation 1) and solving for y:
⇒ y = 3(9) + 34
⇒ y = 27 + 34
⇒ y = 61
Therefore:
x = 9y = 61The cost in dollars of making x

When you enter a number in your answer, do not enter any commas in that number. In other words if you want to enter one thousand, then type in 1000 and not 1,000. It's not possible to understand what the interval (1,000,2,000) means, so you should write that as (1000,2000).
The cost in dollars of making x items is given by the function C(x) = 10x + 900. The fixed cost is 900 dollars. C(25 ) = $1150. The Range is 250.
What is a function?The function is a type of relation, or rule, that maps one input to specific single output.
The cost in dollars of making x items is given by the function
C(x) = 10x + 900
a. The fixed cost is determined when zero items are produced. Find the fixed cost for this item.
The fixed cost
C(0) = 10(0) + 900
= 0 + 900
= $900
b. What is the cost of making 25 items?
C(25) = 10(25) + 900
= 250 + 900
= $1150
Therefore, C(25 ) = $1150
c. Suppose the maximum cost allowed is $1900. What are the domain and range of the cost function, C(x)?
The domain is the set of values for which the given function is defined.
Range = Maximum value of the data set - Minimum value of the dataset
Range = C(25 ) - C(0)
= 1150 - 900
= 250

Step-by-step explanation:
Volume of a triangle prism can be found with;
V = [tex]\frac{1}{2}[/tex] * W * L * H
V = [tex]\frac{1}{2}[/tex] * W * L * H
V = [tex]\frac{1}{2}[/tex] * 8 cm * 14 cm * 8 cm
V = [tex]\frac{1}{2}[/tex] * 8 cm * 14 cm * 8 cm
V = 448 cm³

Answer: D. "Number graph ranging from negative three to three on the x axis and negative two to four on the y axis. A line is drawn on the graph that passes through the points (negative one, zero) and (zero, four)."
Step-by-step explanation:
We know that our graph passes through two given sets of points, therefore we can plug in those points to find the correct answer.
Let's test it with choice A. It gives us the points (0,-6) and (3,0). We can plug these into the equation to see if it is true. y-4 = 2(x+1) becomes
-6-4 = 2(3+1), or -10 = 8 which is not true, so we can eliminate it.
Choice B gives us (0,-4) and (1,0) -4-4 = 2(0+1) or -8 = 2, this one is wrong.
Choice C gives us (-1,0), so 0-4 = 2(-1+1) or -4 = 0, this one is also wrong.
Choice D gives us (-3,0) so 0-4 = 2(-3+1) or -4 = -4. This is the only option which has a correct solution, and therefore it is your answer.

What’s the chord BC?
Answer:
D) 3.8 cm
Step-by-step explanation:
There are several ways this problem can be solved. Maybe the easiest is to use the Law of Cosines to find angle BAC. Then trig functions can be used to find the length of the chord.
__
In triangle BAC, the Law of Cosines tells us ...
a² = b² +c² -2bc·cos(A)
A = arccos((b² +c² -a²)/(2bc)) = arccos((8² +6² -3²)/(2·8·6)) = arccos(91/96)
A ≈ 18.573°
The measure of half the chord is AB times the sine of this angle:
BD = 2(AB·sin(A)) ≈ 3.82222
The length of the common chord is about 3.8 cm.
_____
Additional comment
Another solution can be found using Heron's formula to find the area of triangle ABC. From that, its altitude can be found.
Area ABC = √(s(s-a)(s-b)(s-c)) . . . . where s=(a+b+c)/2
s=(3+8+6)/2 = 8.5
A = √(8.5(8.5 -3)(8.5 -8)(8.5 -6)) = √54.4375 ≈ 7.64444
The altitude of triangle ABC to segment AC is given by ...
A = 1/2bh
h = 2A/b = 2(7.64444)/8 = 1.911111
BD = 2h = 3.822222

Adrian's computer cost 20% less than Jocelyn's computer. Adrian's computer cost $640. Adrian's computer cost 15% more than Corbin's computer. (50 Points)
Answer:
640 = .8j
640 = 1.15c
Step-by-step explanation:
Let j = cost of Jocelyn's computer
c = cost of Corbin's computer
We know that Adrian's computer costs $640.
Since Adrian's computer costs 20% less than Jocelyn's computer, the cost of Adrian's computer is 80% of (.8 times)the cost of Jocelyn's computer, so 640 = .8j
Since Adrian's computer costs 15% more than Corbin's computer, the cost of Adrian's computer is 115% of (1.15 times) the cost of Corbin's computer, so 640 = 1.15c

640 = .8j

Welcome to concept of Inscribed Angle theorem
In the diagram shown above, the inscribed angle m∠SUT intercepts the diameter ST.
Then,
m∠SUT = 90°
In Δ SUT,
m∠S + m∠U + m∠T = 180°
Substitute.
m∠S + 90° + 43° = 180°
m∠S + 133° = 180°
Subtract 133° from each side.
m∠S = 47°
m∠UST = 47°
By Inscribed Angle Theorem,
m∠arc UT = 2 ⋅ m∠UST
Substitute.
(9x - 14)° = 2 ⋅ 47°
(9x - 14)° = 94°
9x - 14 = 94
Add 14 to each side.
9x = 108
Divide each side by 9
x = 12
Hence, we get as x = 12°

Answer:

Step-by-step explanation:

(where (a, b) is the center and r is the radius)
Therefore, we need to rewrite the given equation into the standard form of an equation of a circle.
Given equation:

[tex]\implies x^2+4x+4+y^2-12y+36=-4+4+36[/tex]
Factor both variables:

The Mean Absolute Deviation for the following data: 6, 1, 3, 8, 5, 11, 1, 5 is 2.5
What is mean absolute deviation?The mean absolute deviation of a dataset is the average distance between each data point and the mean.
mean absolute deviation = [tex]\frac{summation|x-mean|}{n}[/tex]

Answer:

Step-by-step explanation:
So, the dimensions of the square are 6*6, so we can find the area of that easily. 6*6 is 36. Now, we have to find the area of the triangle. Since 6 of the 8 cm across were used for the square, we only have 2 cm left to work with. The height of the triangle is 6. The formula to find the area of a triangle is 1/2(b)h. That would mean 1/2*2, which is 1, and then 1*6, which is 6. Finally, we add the areas of both shapes, which is 6 and 36, and we get 42.
