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.

Answer:

y=(4/3)x-4

Step-by-step explanation:

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

[tex]X =\left[\begin{array}{cc}-2 &-11\\4 &-3\end{array}\right][/tex]

Step-by-step explanation:

Given

[tex]R =\left[\begin{array}{cc}0&3\\-4&5\end{array}\right][/tex]

[tex]S =\left[\begin{array}{cc}-2&-8\\0&2\end{array}\right][/tex]

[tex]X + R = S[/tex]

Required

Find X

[tex]X + R = S[/tex]

Make X the subject

[tex]X = S - R[/tex]

Substitute values for S and R

[tex]X =\left[\begin{array}{cc}-2&-8\\0&2\end{array}\right] - \left[\begin{array}{cc}0&3\\-4&5\end{array}\right][/tex]

This can be rewritten as:

[tex]X =\left[\begin{array}{cc}-2 -0 &-8 - 3\\0 - (-4) &2 - 5\end{array}\right][/tex]

[tex]X =\left[\begin{array}{cc}-2 &-11\\4 &-3\end{array}\right][/tex]

Answer:

I am 100% Sure it's A) Suppose that Horace wanted to buy 2 clay pots and 5 plastic pots. Would he be able to get all the pots in one shipment? Explain how you determined your answer.

I think he would be able to get all the pots in 1 shipment because he spent too much time on making money and now he has enough for this.

Step-by-step explanation:

Therefore,he will get all the pots in one shipment.

What is the simplification?

Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

Here given that,

A gardening company sells clay flower pots and plastic flower pots. There must be at least 2 pots in each shipment, but there cannot be more than 8 in a shipment.

Additionally, the shipment must weigh less than [tex]100[/tex] pounds. Each shipment container weighs [tex]20[/tex] pounds, and there is one pound of packing material.

A clay flower pot weighs [tex]15[/tex] pounds, whereas a plastic flower pot weighs [tex]7.5[/tex] pounds.

A) Suppose that Horace wanted to buy [tex]2[/tex] clay pots and [tex]5[/tex] plastic pots.

So as per this information he would be able to get all the pots in one shipment because he is spending too much time on making money and now he has enough for this.

Hence, he will get all the pots in one shipment.

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.

Abby’s Expression:

Double m, giving 2m. She then takes 20% of the result, which we can write 0.2(2m). Finally she subtracts this from 2m, giving 2m−(0.2)2m

2m − (0.2)2m

Renato’s Expression:

Divide m by 5, giving m ÷ 5 = m/5, and then multiplies the result by 8, giving:

8(m/5)

Add 4 and 4 to both sides.

2x=9 42x=9+4

Simplify 9+4 to 13 2 x = 13 2x=13 3

Divide both sides by 2.

Final Result: x= 13/2

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]

The correct answer is given by option d.

Answer:

yes

Step-by-step explanation:

4 7/9 can be rewritten as 4 14/18

2 1/3 can be rewritten as 2 6/18

now the sum can be calculated:

4 14/18 + 2 6/18 = 6 20/18 = 7 2/18

This is within the tolerance of 7 1/18 to 7 3/18, so it will fit.

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:

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]

[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]
