Answer:
A.
Step-by-step explanation:
Give the data set: 2, 4, 6, 8, 10, 12.
Find the following:
Min, Q1, Median, Q3, and Max.
Min. = 2
Q1 = 4
Median = (6+8)/2 = 7
Q3 = 10
Max = 12
Check the box plot to see which one represents these values above.
Thus:
The correct box plot would have the whisker to your left at 2, representing the min value.
The Q1 would be at represented by the beginning box the edge of the rectangular box that starts at 4.
The median would be represented by the vertical line that divides the box which would be on 7.
The Q3 would be on the end of the box which is at 10.
The max would be represented by the other whisker that goes to our right, representing 12.
The box plot is that represents this data is the box plot given in option A.

The probability of a potential employee passing a training course is 86%. If you selected 15 potential employees and gave them the training course, what is the probability that more than 11 will pass the test?
a. 0.648
b.0.900
c. 0.352
d. 0.852
Answer:
d. 0.852
Step-by-step explanation:
For each employee, there are only two possible outcomes. Either they will pass the test, or they will not. The probability of an employee passing the test is independent of other employees. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
The probability of a potential employee passing a training course is 86%.
This means that [tex]p = 0.86[/tex]
Sample of 15.
This means that [tex]n = 15[/tex]
What is the probability that more than 11 will pass the test?
[tex]P(X > 11) = P(X = 12) + P(X = 13) + P(X = 14) + P(X = 15)[/tex]
So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 12) = C_{15,12}.(0.86)^{12}.(0.14)^{3} = 0.204[/tex]
[tex]P(X = 13) = C_{15,13}.(0.86)^{13}.(0.14)^{2} = 0.29[/tex]
[tex]P(X = 14) = C_{15,14}.(0.86)^{14}.(0.14)^{1} = 0.254[/tex]
[tex]P(X = 15) = C_{15,15}.(0.86)^{15}.(0.14)^{0} = 0.104[/tex]
[tex]P(X > 11) = P(X = 12) + P(X = 13) + P(X = 14) + P(X = 15) = 0.204 + 0.29 + 0.254 + 0.104 = 0.852[/tex]

A contestant in a weight loss competition wants to lose an average of at least 8 pounds
per month during a 5-month period. In the first 4 months they have lost the following
weight: 12 lbs, 9 lbs, 5 lbs, 8 lbs. How many pounds must the contestant lose in the fifth
month to meet the goal?
Answer:
In the fifth month the contestant must lose 6 pounds of weight.
Step-by-step explanation:
Given that the contestant wants to lose an average of 8 pounds of weight per month for 5 months, taking into account that in the first 4 months of the contest he lost 12, 9, 5 and 8 pounds respectively, to determine how much weight he should lose in the fifth month the following calculation must be performed:
8 x 5 = 40 (pounds to lose)
12 + 9 + 5 + 8 = 34 (pounds lost)
40 - 34 = 6
Therefore, in the fifth month the contestant must lose 6 pounds of weight.

[tex]5 - 2x^2 = - 15[/tex]
Answer:
[tex]x=\sqrt{10}[/tex]
Step-by-step explanation:
The given equation is :
[tex]5-2x^2=-15[/tex]
We need to solve it using inverse operations.
Subtract 5 from both sides of the equation.
[tex]5-2x^2-5=-15-5\\\\-2x^2=-20\\\\2x^2=20\\\\x^2=10\\\\x=\sqrt{10}[/tex]

Three friends (A, B, and C) will participate in a round-robin tournament in which each one plays both of the others. Suppose that
P(A beats B) = 0.5
P(A beats C) = 0.6
P(B beats C) = 0.9
and that the outcomes of the three matches are independent of one another.
a. What is the probability that A wins both her matches and that B beats C?
b. What is the probability that A wins both her matches?
c. What is the probability that A loses both her matches?
d. What is the probability that each person wins one match? (Hint: There are two different ways for this to happen.)
Answer:
0.27 ; 0.30 ; 0.20 ; 0.21
Step-by-step explanation:
Given that :
P(A beats B) = 0.5
P(A beats C) = 0.6
P(B beats C) = 0.9
Since the outcomes are independent :
A.) probability that A wins both her matches and that B beats C
P(A beats B) * P(A beats C) * P(B beats C)
0.5 * 0.6 * 0.9 = 0.27
B.) probability that A wins both her matches
P(A beats B) * P(A beats C)
0.5 * 0.6 = 0.3
C.) probability that A loses both her matches?
(1 - P(A beats B)) * (1 - P(A beats C)
(1 - 0.5) * (1 - 0.6)
0.5 * 0.4 = 0.20
D.) probability that each person wins one match
Either (A beats B), (B beats C). (C beats A) OR (A beats C), (C beats B), (B beats A)
Hence;
(0.5 * 0.9 * (1 - 0.6)) + (0.6 * (1 - 0.9) * (1 - 0.5)) = 0.21

The ratio of number of male and female teachers in a school is 3:4. Find the number of male teachers if there are 16 female teachers
Answer:
12 male teachers
Step-by-step explanation:
If the ratio is 3:4, and the number of female teachers is 16, then the number of male teachers must be 12. This can be confirmed by multiplying both 3 and 4 by 4, or 12/16 = 3/4.
Answer:
12 male teachers.
Step-by-step explanation:
if there is 16 females and the ratio is 3:4 it would be 12 due to 4 times 4 being 16. Meaning that i would do 3 times 4 which would result in having 12 male teachers.

Given that a varied inversely as b, and b varies directly as the square of c, and a=1 when c=3 find the value of a when c=1/3
Please I need solvings for this thanks
Answer:
81
Step-by-step explanation:
When two variables have direct variation, as one variable increases the other variable increases or as one variable decrease, the other decrease. While for an inverse variation, as one variable increase, the other variable decrease or as one variable decrease, the other variable increase.
Given that a ∝ 1/b. Also b ∝ c².
Hence if k is the constant of proportionality, we have:
a ∝ 1 / c²
a = k / c²
When a = 1, c = 3, hence:
1 = k / 3²
k = 1 * 3²
k = 9
Therefore:
a = 9 / c²
When c = 1/3
a = 9 / (1/3)²
a = 9 / (1² / 3²)
a = 9 / (1 / 9)
a = 9 * 9
a = 81
