Answer:

Here we have four individual events.

First selection, second selection, third selection and fourth selection.

Where initially, the options are 16 Americans and 13 Canadians.

Now, to see if the events are dependent or independent.

Suppose that in the first selection, an American is selected.

Then the second selection has 15 Americans and 13 Canadians as options.

Now, if in the first selection, a Canadian is selected.

Then in the second selection, the options will be 16 Americans and 12 Canadians.

Then the events are not independent.

Now we want to find the probability of randomly selecting a four-person committee consisting entirely of Canadians from a pool of 16 Americans and 13 Canadians

The probability of randomly selecting a Canadian is equal to the quotient between the number of Canadians, and the total number of postulants.

For the first selection, we have 13 Canadians, and 29 people in total, then the probability is:

P1 = 13/29.

Suppose that a Canadian is selected, now there are 12 Canadians and 28 people in total, then the probability for the second selection is:

P2 = 12/28

with the same reasoning as above, the probabilities for the third and fourth selections will be:

P3 = 11/27

P4 = 10/26.

The joint probability will be equal to the product of the individual probabilities, this is:

P = P1*P2*P3*P4 = (13/29)*(12/28)*(11/27)*(10/26) = 0.03

Answer:

x=12

Step-by-step explanation:

[tex] - 2x - 12 = - 36[/tex]

[tex] - 2x = - 36 + 12[/tex]

[tex] - 2x = - 24[/tex]

[tex]x = - 24 \div - 2[/tex]

[tex]x = 12[/tex]

Answer:

The answer is x=12

Step-by-step explanation:

-2(x+6)= -36

-2x+-12=-36

-2x+-12+12=-36+12

-2x=-24

Divide both sides by -2

-2x/2=-24/-2

x=12

Answer:

So, the distance covered by man if he takes 3 rounds is 3491.16 inches

Step-by-step explanation:

We are given area of square field i.e 84642 and we need to find distance covered by man if he takes 3 rounds of the field.

Distance covered by man = Perimeter of square field

First we have to find length of side of square field.

The formula used is Area of square= (Length)^2

Putting value of area and finding length.

[tex]Area of square= (Length)^2\\\sqrt{Length} =\sqrt{84642} \\Length= 290.93\\[/tex]

So, length of square field is 290.93 inches

Now finding the distance covered by man if he takes 3 rounds

First find perimeter

Perimeter of square = 4*length

Perimeter of square = 4*290.93

Perimeter of square = 1163.72 inches

Distance covered by man if he takes 3 rounds = 3*Perimeter of square

Distance covered by man if he takes 3 rounds = 3*1163.72

So, the distance covered by man if he takes 3 rounds is 3491.16 inches

Answer:

24 toys

Step-by-step explanation:

line up your numbers by the type of unit they have :

80 toys represent  100% of the toys

  ? toys represent  30% that are stuffed animals

Cross-multiply

?*100 = 30*80

divide both sides by 100

?= 30*80/100= 24

H(- 1 ,1) ----> [k(- 1), k(1)] ----> G(2, - 2) ⇒ k = - 2

M( - 1.5, - 4) -----> [(- 2)(- 1.5) , (- 2)(- 4)] ------> R(3. 8)

k = - 2

Inequalities Of The Form “x – a < b” or “x – a > b”

The solution of the inequality 1 1/8 + b ≥ 7/16 will be;

⇒ - 11/16 ≤ b

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The inequality is,

⇒ 1 1/8 + b ≥ 7/16

Now,

Solve the inequality as;

The inequality is,

⇒ 1 1/8 + b ≥ 7/16

Solve for b as;

⇒ 9/8 + b ≥ 7/16

Subtract 9/8 as,

⇒ 9/8 + b - 9/8  ≥ 7/16 - 9/8

⇒ b ≥ (7 - 18) / 16

⇒ b ≥ - 11/16

⇒ - 11/16 ≤ b

Thus, The solution of the inequality 1 1/8 + b ≥ 7/16 will be;

⇒ - 11/16 ≤ b

hello your question is incomplete attached below is the complete question and solution

Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified line. Sketch the region, the solid, and a typical disk or washer.

y = x^2  ,  x = y^2   about  x = -1

answer : [tex]\frac{29\pi }{30}[/tex]

Step-by-step explanation:

given curves = y = x^2 and x = y^2

we determine the inner and outer radii using the washer method

inner radius = R2(y) = 1 + y^2

outer radius = R1 (y) = 1 + [tex]\sqrt{y}[/tex]

volume of the solid = [tex]\frac{29\pi }{30}[/tex]
