Step-by-step explanation:
In a classic Conan Doyle story, Sherlock Holmes solves a crime mystery by recognizing that a guard dog didn't bark. Therefore, the dog must have known the perpetrator. Holmes' reasoning goes like this: if the guard dog doesn't know a person, then it barks. The dog didn't bark. Therefore, it knew the person.
Which rule of inference is being used here?
a. Addition.
b. Simplification.
c. Conjunction.
d. Modus Ponens.
e. Hypothetical Syllogism.
f. Disjunctive Syllogism.
g. Modus Tollens.
h. Resolution.
Answer:
G. Modus tollens
Step-by-step explanation:
This question used the inference called modus tollens.
Modus tollens is a a valid form of argument that is of this form below:
If S, then T
if not S, then not T.
S = dog doesn't know perpetrator
Not S = dog knows who the perpetrator is
T = the dog barked
Not T = the dog did not bark.
So if we put this into the statement in bold letters, we would have:
The dog doesn't know perpetrator, so it barked.
And,
The dog didn't bark, so it knows the perpetrator.

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]

8 Prove that 8^6+4^11 is divisible by 17. Answer __*17
Answer:
262,144 goes in the blank
Step-by-step explanation:
8^6 = 262,144
4^11 = 4,194,304
4,194,304 + 262,144 = 4,456,448
4,456,448 ÷ 17 = 262,144
You can use the fact that 8 is cube of 3 and 4 is square of 2.
The value in the blank space given is [tex]2^{18}[/tex]
Given that:To prove that [tex]8^6+4^{11}[/tex] is divisible by 17Converting [tex]8^6+4^{11}[/tex] in terms of 2:[tex]8^6 = (2^3)^6 = 2^{3 \times 6} = 2^{18}[/tex]
[tex]4^{11} = (2^2)^{11} = 2^{2 \times 11} = 2^{22} [/tex]
Thus,
[tex]8^6 + 4^{11} = 2^{18} + 2^{22} = 2^{18}(1 + 2^{4}}) = 2^{18} \times 17[/tex]
Thus, it is multiple of 17 and thus, divisible by 17.
The value in the blank space given is [tex]2^{18}[/tex]

Since the slope and one point are given to us we can put this equation into slope-point form. This is [tex]y-y_{1}=m(x-x_{1})[/tex], so this equation would be y-4=6(x+4). Then solve for y to get the final equation. Once solved for y the slope-intercept equation is y = 6x + 28.

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.

Answer:

Step-by-step explanation:
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

Answer:
77/134 or 0.5746
Step-by-step explanation:
The approximate relative frequency is "the number of times that the event occurs during experimental trials, divided by the total number of trials conducted."
So we need to identify the number of times the event occured, the amount of times children chose sweet snacks, and the total number of trials conducted. So since the question wants the approximate relative frequency by column, we use the number 134 for the total number, and 77 for the number of times the event occurred. We then divide 77 by 134, which looks like this: 77/134. In decimal form, this equals 0.5746. It can't be simplified anymore in fraction form, so 77/135 would be another way to answer.
