The following data were given in a study of a group of 1000 subscribers to a certain magazine. In reference to job, marital status, and education, there were
312 professionals,
470 married persons,
525 college graduates,
42 professional college graduates,
147 married college graduates,
86 married professionals,
25 married professional college graduates.
(i) Let a person be picked at random. Determine the probability that the person is married or professional or college graduate.
(ii) Explain why the numbers reported in the study must be incorrect.
Answer:
[tex](a)[/tex] [tex]P(M\ or\ P\ or\ C) = 1.307[/tex]
(b) See Explanation
Step-by-step explanation:
Given
[tex]P = 312[/tex] ---- Professionals,
[tex]M = 470[/tex] ----- Married persons,
[tex]C = 525[/tex] ---- College graduates,
[tex]PCG = 42[/tex] ----- Professional college graduates,
[tex]MCG = 147[/tex] ----- Married college graduates,
[tex]MP = 86[/tex] ---- Married professionals,
[tex]MPCG = 25[/tex] ---- Married professional college graduates
[tex]Total =1000[/tex]
Solving (a): P(M or P or C)
This is calculated as:
[tex]P(M\ or\ P\ or\ C) = P(M) + P(P) + P(C)[/tex]
[tex]P(M\ or\ P\ or\ C) = \frac{n(M) + n(P) + n(C)}{Total}[/tex]
[tex]P(M\ or\ P\ or\ C) = \frac{470 + 525 + 312}{1000}[/tex]
[tex]P(M\ or\ P\ or\ C) = \frac{1307}{1000}[/tex]
[tex]P(M\ or\ P\ or\ C) = 1.307[/tex]
(b) In probabilities, the probability of an event or collection of events must not exceed 1 and must not go below 0.
In (a) above, the calculated probability exceeds 1.
Because of this single reason, the collected data is incorrect
write in decimal.

Pls help this is due today ! Find the value x:
Answer:
x= 12
Step-by-step explanation:
180° = (3x - 6) + (8x + 4) + 50° because all interior angles of a triangle add up to 180°
180° = 11x +48°
11x = 132°
x = 12
True or False:
There are an infinite number of answers for this equation:
63 - X = 34
Answer: No, the answer is 29, this is false.
Step-by-step explanation: 63-x=34
subtract 63 from both sides
34-63= -29
-x=-29
divide both sides by the negative and you get 29
plug in 29 for x, 63-29=34

A crowd-funding project has received $16,770, which is $1230 less than 90% of the goal amount. What is the goal amount?
Answer:
The goal is $19,800.
Step-by-step explanation:
$16,770 is $1,230 less than %90 of the goal. If you add 16,770 and 1,230, you get 18,000. Then you have to multiply that by 1.10 to get it to the goal. That is how you get $19,800, which is the answer.

Find the area of the following
triangle:
4.2 cm
3 cm
10 cm
A= [?] cm
Answer:
15 cm
Step-by-step explanation:
Base x height / 2 = Area(of a triangle) =
3 x 10 / 2 =
15 cm
The solution is : the area of the following triangle is, 15 cm².
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
Here, we have,
given that,
4.2 cm
3 cm
10 cm
We know that,
area = bh/2
i.e. we get,
Base x height / 2
= Area(of a triangle)
substituting the values, we get,
= 3 x 10 / 2
= 15 cm²
Hence, The solution is : the area of the following triangle is, 15 cm².

Answer:
It landed at a height of 14 feet
Step-by-step explanation:
Given
[tex]y = -\frac{1}{8}x^2 +4x[/tex] --- Path of a t-shirt
[tex]3y = 2x - 14[/tex] --- height of bleachers
Required
Height when t-shirts land in bleachers
[tex]3y = 2x - 14[/tex]
Make y the subject
[tex]y = \frac{2}{3}x - \frac{14}{3}[/tex]
Substitute [tex]y = \frac{2}{3}x - \frac{14}{3}[/tex] in [tex]y = -\frac{1}{8}x^2 +4x[/tex]
[tex]\frac{2}{3}x - \frac{14}{3} = -\frac{1}{8}x^2 +4x[/tex]
Multiply through by 24
[tex]16x- 112 = -3x^2 +96x[/tex]
Express as:
[tex]3x^2 + 16x -96x- 112 = 0[/tex]
[tex]3x^2 -80x- 112 = 0[/tex]
Using a calculator:
[tex]x = 28[/tex] or [tex]x = -\frac{4}{3}[/tex]
x can not be negative:
So:
[tex]x = 28[/tex]
Substitute [tex]x = 28[/tex] in [tex]y = -\frac{1}{8}x^2 +4x[/tex] to calculate the height it landed
[tex]y = -\frac{1}{8} * 28^2 + 4 * 28[/tex]
[tex]y = 14[/tex]

What is the distance between points A and B shown in the graph below
Answer:
[tex]D = 7\sqrt 2[/tex]
Step-by-step explanation:
Given
[tex]A = (-3,-4)[/tex]
[tex]B = (4,3)[/tex]
Required
The distance between them
This is calculated as:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
So, we have:
[tex]D = \sqrt{(3-(-4))^2+(4-(-3))^2}[/tex]
[tex]D = \sqrt{7^2+7^2}[/tex]
[tex]D = \sqrt{2(7^2)}[/tex]
[tex]D = 7\sqrt 2[/tex]
Evelyn is making bows from blue and white ribbon. She uses 6 in. of blue ribbon
for every 9 in. of white ribbon. Evelyn has 82 in, of blue ribbon and 114 in. of white
ribbon. Which color of ribbon will she run out of first? Explain.
Answer:
White
Step-by-step explanation:
W: 114/9 ≈ 12.67 9-inch ribbons
12.67(6) = 76 < 82
Evelyn will run out of white ribbon first as she can use it for 12 times compared to 13 times.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, She uses 6 in. of blue ribbon and has a total of 82 inches,
So, The number of times she can use is,
= (82/6) times.
= 13.66 times.
Similarly, The number of times she can use the white ribbon is,
= (114/9) times.
= 12.66 times.
Therefore, She will run out of white ribbons first.
