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

t

[tex]step - 1 : \: define[/tex]

[tex] - 4 {t}^{2} + 12t + 100 = 0[/tex]

[tex]step - 2 : \\ divide \: both \: sides \: by \: - 4[/tex]

[tex] {t}^{2} - 3t - 25 = 0[/tex]

[tex]step - 3 : \\ solve \: the \: quadratic[/tex]

[tex]formula : \\ x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} [/tex]

[tex]define \: a ,b \: and \: c \\ which \: are \: 1, - 3 \: and \: - 25 \: respectively[/tex]

[tex]t = \frac{ - ( - 3)± \sqrt{ {( - 3)}^{2} - 4.1. - 25 } }{2.1} [/tex]

[tex]t = \frac{ 3± \sqrt{ 9 + 100} }{2} [/tex]

[tex] t = \frac{3 + \sqrt{ 109 } }{2} [/tex]

[tex]t = \frac{3 - \sqrt{ 109 } }{2} [/tex]

[tex]t = 6.7 \\ t = - 3.7[/tex]

[tex]as \: we \: know \: time \: cannot \: be \: negative[/tex]

Total                                       40                  50                       90

First missing place = 50-24 = 26

Second missing place = 26+26 = 52

Third missing place = 38-24 = 14

Fourth missing place = 26+14 = 40

Fifth missing place = 90-40 = 50

Hence, The values in the missing places are 26, 52, 14, 40 and 50

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.

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]

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:

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

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]

So, the solution of the given equation is [tex]x=\sqrt{10}[/tex].

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:

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.
