Find the marginal distribution of military status in percentages. Round to the nearest whole percent.
The question is incomplete. Here is the complete question.
Mavis is interested whether military status is related to gender in American Samoa. The data she collected about the population of American Samoa in 2010 is below.
Find the marginal distribution of military status in percentages. Round to the nearest whole percentages.
In Armed Forces:
Military-dependent:
Civilian:
Answer: In Armed Forces: 0%
Military-dependent: 3%
Civilian: 97%
Step-by-step explanation: Marginal Distribution is defined as the probability distribution of variables contained in a subset.
For the American Samoa's military status, marginal distribution is
1) In Armed Forces:
[tex]p_{1}=\frac{87}{55,519}*100[/tex]
[tex]p_{1}=0.15[/tex]
2) Military-dependent:
[tex]p_{2}=\frac{1709}{55,519}*100[/tex]
[tex]p_{2}=3.08[/tex]
3) Civilian:
[tex]p_{3}=\frac{53,723}{55,519}*100[/tex]
[tex]p_{3}=96.77[/tex]
Now round each percentage to the nearest whole percentage:
Armed forces: 0%
Military: 3%
Civilian: 97%
The marginal distributions of military status are, in nearest whole percentage:
Armed forces: 0%
Military: 3%
Civilian: 97%
Which expression represents the perimeter of the rectangle below?
A. 13x - 31
B. 13x - 55
C. 26x - 62
D. 26x-124
The perimeter of the rectangle given is P = 26x - 62.
What is the perimeter of a rectangle?
The perimeter of a rectangle is the sum of its sides. Mathematically -
Perimeter = [P] = 2(L + B)
Given is a rectangle with its length and breadth.
We can write the perimeter of the rectangle as follows -
[P] = 2(L + B)
L = 5x + 12
B = 8x - 43
Therefore -
P = 2(L + B)
P = 2(5x + 12 + 8x - 43)
P = 2(13x - 31)
P = 26x - 62
Therefore, the perimeter of the rectangle given is P = 26x - 62.

Sue is 15 years older than Mike. in 5 years mikes’s age will be ½ sue’s age. What is the present age of each?
Show work!!!!
Answer:
5
Step-by-step explanation:
Sue in 5 years would 20, meaning Mike would be 10. Subtract 5 from Mike to get their current age.
Answer:
Mike= 10 years old
Sue= 25 years old
Step-by-step explanation:
Let the present age of Sue be s years old, while that of Mike be m years old.
Present
s= m +15 -----(1)
In 5 years
Sue's age= s +5
Mike's age= m +5
Given that Mike would be ½ of Sue's age in 5 years,
m +5= ½(s +5)
Multiply both sides by 2:
2(m +5)= s +5
Expand:
2m +10= s +5
2m +10 -5= s
s= 2m +5 -----(2)
Substitute (1) into (2):
m +15= 2m +5
2m -m= 15 -5
m= 10
Substitute m= 10 into (1):
s= 10 +15
s= 25
Thus, the present age of Mike is 10 years old and the present age of Sue is 25 years old.

Answer:
The length of [tex]\overline{JO}[/tex] is 48.
Step-by-step explanation:
A square is a quadrilateral whose four sides have the same length and four internal angles have the same measure. The sum of measures of internal angles in quadrilaterals equals 360°. Let [tex]m\,\angle BOJ = 4\cdot x -6[/tex] and [tex]BO = 2\cdot x - 8[/tex], the value of [tex]x[/tex] is:

The image below shows two parallel lines and an intersecting transversal line. What is the degree measures of angles 1 and 2?
the answer is A because 1 is the same as 78
helpppppp pleaseeeeee
Answer:
50°
Step-by-step explanation:
We are to find m ∠2
And lines A and B are parallel
m ∠2 and 50° are Vertical angles. This means m ∠2 is the same as 50°
Hence,
m ∠2 = 50°
Therefore, m ∠2 = 50°
Mrs. Dawson is researching what it would cost to order flower arrangements for a fancy party. She wants one large centerpiece for the head table, and smaller arrangements for the smaller tables. Hampton Florist charges $12 for each smaller arrangement, plus $27 for the large centerpiece. Farid's Flowers, in contrast, charges $32 for the large centerpiece and $7 per arrangement for the rest. If Mrs. Dawson orders a certain number of small arrangements, the cost will be the same at either flower shop. How many small arrangements would that be? What would the total cost be? If Mrs. Dawson orders small arrangements, it will cost $ at either shop.
The number of flower arrangement and the costs are illustrations of linear equation
If Mrs. Dawson orders 1 small arrangement, it will cost $39 at either shop.
How to determine the number of small arrangements?Represent the number of small arrangements with x, and the total cost with y.
Using the data from the question, we have:
Hampton Florist: y = 12x + 27.
Farid's Flowers: y = 32 + 7x
When both flower arrangements cost the same, we have the following equation
12x + 27 = 32 + 7x
Collect like terms
12x - 7x = 32 - 27
Evaluate the like terms
5x = 5
Divide both sides by 5
x = 1
This means that 1 small arrangement would cost the same in both flower shops
How to determine the total cost?In (a), we have:
y = 12x + 27.
Substitute 1 for x
y = 12(1) + 27
y = 39
Hence, if Mrs. Dawson orders 1 small arrangement, it will cost $39 at either shop.

Marcie Ann Weber, age 32, takes out $15,000 of a term insurance for a ten year term.
a. annual premium: $ a0
b. monthly premium: $ a1
Answer:
Step-by-step explanation:
a. annual premium: 79.35
b. monthly premium: 7.14
Marcie Ann Weber, age 32, takes out $15,000 of a term insurance for a ten-year term. Annual premium = $1,500 per year and monthly premium = $125 per month.
What is division?One type of operation is division in mathematics. In this procedure, the phrases or numbers are divided into the same number of components.
Given: Marcie Ann Weber,
insured amount of term insurance plan = $15,000.
Number of year = 10 year
To find the amount of annual premium:
Divide the total insured amount by number of years.
Annual premium = Insured amount of term insurance plan / Number of year
Annual premium = $15,000 / 10
Annual premium = $1,500 per year
To find the amount of monthly premium:
Monthly premium = Insured amount of term insurance plan / Number of month in 10 year
Monthly premium = 15,000 / (10 x 12)
Monthly premium = 15,000 / 120
Monthly premium = $125 per month.
Therefore, annual premium = $1,500 per year and monthly premium = $125 per month.

1.5 by 9 by 12
Answer:
891 ft³
Step-by-step explanation:
First I'll find the volume of the rectangular prism. (l * w * h)
12 * 9 * 7.5
Multiply 12 by 9 to get 108.
108 * 7.5
Now, multiply 108 by 7.5 to get 810. (756 + 54 = 810)
810
Now for the triangular prism. (1/2(l * w * h))
1/2(12 * 9 * 1.5) (I figured the height was 1.5 since the height of the rectangular prism was 7.5; the entire figure's height was 9)
Multiply 12 by 9 to get 108.
1/2(108 * 1.5)
Multiply 108 by 1.5 to get 162. (108 + 54 = 162)
1/2(162)
Multiply 162 by 1/2 to get 81. (162/2)
81
Now add that to 810 to get 891.
810 + 81
891 ft³

Find the measure of each labeled angle A(3x-20) B(2x) C (2x-15)
Answer:
Measure of angle A = 100°
Measure of angle B = 80°
Measure of angle C = 65°
Step-by-step explanation:
From the given picture,
Angle A and angle B are the linear pair of angles, and linear pair of angles are supplementary angles,
m(∠A) + m(∠B) = 180°
(3x - 20)° + (2x)° = 180°
5x - 20 = 180
5x = 200
x = 40
By substituting the value of x in the measures of each angle,
m(∠A) = (3x - 20)°
= 3(40) - 20
= 120 - 20
= 100°
m(∠B) = 2x°
= 2(40)
= 80°
m(∠C) = (2x - 15)°
= 2(40) - 15
= 80 - 15
= 65°
