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

OB. h() = -4(x - 2)(x + 2)
Och(x) = -47 +16
OD. H(x) = -2(2x - 3)
Answer:
Step-by-step explanation:
h(x) = -4(x-2)(x+2)
The zeros are 2 and -2.
Answer:

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]

Here is a grid of squares.
Write down the ratio of the number of unshaded squares to the number of
shaded squares.
Answer:
3/10
Step-by-step explanation:
............iam not sure
The required ratio of the unshaded square to the shaded square is 7 : 3.
Given that,
To determine the ratio of the number of unshaded squares to the number of shaded squares.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Number of shaded squares = 3
number of unshaded squares = 7
Required ratio = 7 / 3 = 7 : 3
Thus, the required ratio of the unshaded square to the shaded square is 7 : 3.

Item 15
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.

A beach resort has 29 jet skis for guests to rent. Of these, 14 are two-person skis, 18 haveturbo packs, and 10 are both for two persons and have turbo packs. LetTbe the event that a jetski, randomly chosen, is a two-person ski, and letPbe the event that the ski has a turbo pack.A jet ski is chosen at random for rental. Find the probability for each of the following events.
Questions:
a. The jet ski is for two persons and has turbo packs.
b. The jet ski is not for two persons but has turbo packs.
Answer:
[tex]P(P\ and\ T) = \frac{10}{29}[/tex]
[tex]P(P\ and\ T') = \frac{270}{841}[/tex]
Step-by-step explanation:
Given
[tex]n=29[/tex] --- Total
[tex]T = 14[/tex] --- Two person skis
[tex]P = 18[/tex] --- Turbo packs skis
[tex]P\ and\ T = 10[/tex] --- Two person ski and Turbo packs
Solving (a):
This is represented as: [tex]P(P\ and\ T)[/tex]
This is calculated as:
[tex]P(P\ and\ T) = \frac{n(P\ and\ T)}{n}[/tex]
[tex]P(P\ and\ T) = \frac{10}{29}[/tex]
Solving (a):
This is represented as: [tex]P(P\ and\ T')[/tex]
This is calculated as:
[tex]P(P\ and\ T') = P(P)\ and\ P(T')[/tex]
[tex]P(P\ and\ T') = P(P)\ *\ P(T')[/tex]
Using the complement rule, we have:
[tex]P(T') = 1 - P(T)[/tex]
The equation becomes:
[tex]P(P\ and\ T') = P(P)\ *\ [1 - P(T)][/tex]
[tex]P(P\ and\ T') = \frac{n(P)}{n}\ *\ [1 - \frac{n(T)}{n}][/tex]
[tex]P(P\ and\ T') = \frac{18}{29}\ *\ [1 - \frac{14}{29}][/tex]
[tex]P(P\ and\ T') = \frac{18}{29}\ *\ \frac{29-14}{29}[/tex]
[tex]P(P\ and\ T') = \frac{18}{29}\ *\ \frac{15}{29}[/tex]
[tex]P(P\ and\ T') = \frac{18*15}{29*29}[/tex]
[tex]P(P\ and\ T') = \frac{270}{841}[/tex]
