Computation to determine the probability of eligible voter selected at random
First step is to Draw up a contingincy table which will include Rows = Degree/No degree
and Columns= Vote/Not vote
..............Vote..No vote
Degree 80...20...100
(80%*100=80)
(100-80=20)
No Degree 504..396..900
(1000-100=900)
(56%*900=504)
(504-900=396
Totals 584..416...1000
(80+504=584)
(20+396=416)
(900+100=1,000)
Summary
..............Vote..No vote
Degree 80...20...100
No Degree 504..396..900
Total Totals 584..416...1000
A. Calculation to determine the probability of The voter had a college degree and voted in the last presidential election.
P = 80/1,000
P=0.08*100
P=8%
Therefore the probability of The voter had a college degree and voted in the last presidential election will be 8%
B. Calculation to determine the probability of The voter did not have a college degree and did not vote in the last presidential election.
P =396/1000
P=0.396*100
P=39.6%
Therefore the probability of The voter did not have a college degree and did not vote in the last presidential election will be 39.6%
C. Calculation to determine the probability if The voter voted in the last presidential election.
P = 584/1,000
P=0.584*100
P=58.4%
Therefore the probability if The voter voted in the last presidential election will be 58.4%
D. Calculation to determine the probability if The voter did not vote in the last presidential election.
P = 416/1000
P=0.416*100
P=41.6%
Therefore the probability if The voter did not vote in the last presidential election will be 41.6%

What value of x makes the equation, -3 + 4x + 3(4x + 8)=4(7x + 3)-3 true?
Answer:
x = 1
Step-by-step explanation:
-3 + 4x + 3(4x + 8) = 4(7x + 3) - 3
first, solve the brackets by using the distributive property of multiplication:
3(4x + 8) = 12x + 24
4(7x + 3) = 28x + 12
rewrite equation:
-3 + 4x + 12x + 24 = 28x + 12 - 3
combine like terms:
16x + 21 = 28x + 9
subytact 21 on both sides:
16x + 21 - 21 = 28x + 9 - 21
16x = 28x - 12
subtract 28x on both sides:
16x - 28x = 28x - 28x - 12
-12x = -12
divide both sides by 12
[tex]\frac{-12x}{12} = \frac{12}{12}[/tex]
x = 1
to check, substitute 1 for x:
-3 + 4(1) + 3(4(1) + 8) = 4(7(1) + 3) - 3
-3 + 4 + 12 + 24 = 28 + 12 - 3
37 = 37

What is the operation in the equation 4a = 24?
Answer: a=6
Step-by-step explanation: Divide each term by 4 and simplify
Answer:
a=6
Step-by-step explanation:

4a - 24 = 4 • (a - 6)
4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
So a=6

Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the quadrilateral. Show
your work.
Answer:
A= 94°, B = 102°, C = 86°, D = 78°Step-by-step explanation:
ABCD is a cyclic quadrilateral
It has the property that opposite angles are supplementary: A with C and B with D.
Solve following for x:
x + 6 + x - 2 = 180°2x + 4 = 180°2x = 176°x = 88°The angles are:
A = 88° + 6° = 94°C = 180° - 94° = 86°D = 88° - 10° = 78°B = 180° - 78° = 102°Helppppppppppppppppppp

1. Subtract 5 from both sides of the equation.
6 + 5 = 3 + 1 4 6 + 5 − 5 = 3 + 1 4 − 5
2. Simplify
Subtract the numbers 6 = 3 + 9
3. Subtract 3x from both sides of the equation.
6 = 3 + 9 6 − 3 = 3 + 9 − 3
4. Simplify.
Combine like terms - 3x = 9
5. Divide both sides of the equation by the same term
3 = 9 3 3 = 9 3
6. Simplify
Cancel terms that are in both the numerator and denominator Divide the numbers = 3

EQ: How do you use elimination to solve a system of
equations?
Answer:
Step-by-step explanation:
when you use elimination you want to set two of the terms, in the different equations, equal to each other and then subtract the entire equation from the other, so that the two terms cancel out. Then you have an equation with one less variable in it. :)

Select all the chord(s) in circle G.
DF, EB and FA are the chords in circle G.
What are the properties of the circle?Circles have the following characteristics:
All points in a plane equally spaced from a fixed end known as the centre make up the circle, a closed curve.The radius of the circle is the distance measured from any point in the process to its centre. A circle's radii are all the same size.A section of a straight line connecting two locations on a circle's surface and passing through its centre is said to be the circle's diameter. The radius is twice as long as the diameter.A straight line segment that joins two points on a circle is known as a chord. How to spot a chord is as follows:
On the circle, look for two spots that are not obliquely opposite one another.From these two places, a straight line should be drawn. This line forms one of the circle's chords.Any line segment that crosses the circle at two different locations is also known as a chord.The diameter of a circle is a unique kind of chord that splits the circle in half evenly in the centre.Thus, from the above properties the chord of the given circle G will be DF, EB and FA.

The curved surface area of a cylinder of height 28cm is 352sq.cm. Find the diameter of the base of the cylinder
Answer:
d = 4cm
Step-by-step explanation:
curved surface area (CSA) of cylinder = [tex]2\pi rh[/tex]
h = 28cm and CSA = 352[tex]cm^{2}[/tex]
[tex]2\pi rh[/tex] = 352
2 * [tex]\frac{22}{7}[/tex] * r * 28 = 352
[tex]r = \frac{352*7}{2*22*28}[/tex]
after calculating, you will get r = 2cm

Answer:
x = 24, y = 19
Step-by-step explanation:
Form the question,
Note: opposite side of a parallelogram are equal.
From the diagram,
2x-8 = x+16
Solve for x.
Collect like terms
2x-x = 16+8
x = 24.
Also,
2y = y+19
Solve for y
Collect like terms
2y-y = 19
y = 19.
Hence, x = 24, y = 19.

Which function describes the arithmetic sequence shown?
7,9, 11, 13, 15, 17,
A)
f(x) = 2x - 5
B)
f(x) = 5x - 2
C)
f(x) = 2x + 5
D)
f(x) = 5x + 2
Answer:
f(x) = 2x+5
Step-by-step explanation:
Given the arithmetic sequence shown
7,9, 11, 13, 15, 17,
THe nth term of the sequence is expressed as;
Tn = a + (n-1)d
a is the first term = 7
d is the common difference = 9-7 = 11-9 = 2
Substitute
Tn = 7 + (n -1)*2
Tn = 7 + 2n - 2
Tn = 2n + 5
Hence the required function is f(x) = 2x+5

Instant Meals sent out free samples to introduce its new product, Sesame soup. Each sample weighs 69 g. The post office charges thirty-six cents for every 23 g of weight. How much would Instant Meals spend on postage to mail out one hundred eighty-eight samples?
Answer:
$203.04
Step-by-step explanation:
The computation is shown below:
23 ounces to be $0.36
And,
69 ounces be x
So here x
= (69 ounces × $0.36) ÷ 23 ounces
= $1.08
Since there is 188 samples, so the total value is
= $1.08 × 188
= $203.04
