Answer:

0.1732 = 17.32% probability exactly 24 residents own a home.

Step-by-step explanation:

For each resident, there are only two possible outcomes. Either they own a home, or they do not. The probability of a resident owning a home is independent of any other resident. This means that the binomial probability distribution is used 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.

78% of residents in Summerville own a home.

This means that [tex]p = 0.78[/tex]

30 residents are randomly selected:

This means that [tex]n = 30[/tex]

Find the probability exactly 24 residents own a home.

This is P(X = 24).

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 24) = C_{30,24}.(0.78)^{24}.(0.22)^{6} = 0.1732[/tex]

0.1732 = 17.32% probability exactly 24 residents own a home.

Answer:

165

Step-by-step explanation:

1. you have to do 10 x 8 bc she makes 10 dollars a week, and it says how much will she make in 8 weeks so you do 10 x 8. 10 x 8 = 80 , so you take the 85 dollars she has then you take the 80 and add them together and you get 165.

Answer:

∠3 = 18°

∠4 = 144°

∠2 = 36°

∠1 = 72°

Step-by-step explanation:

From the concept of alternate interior angles,

∠3 = 18°

Since the diagonal divides the rectangle into 4 parts with 2 of the rectangles being similar.

Then, the triangle with ∠3 & ∠4 is an Isosceles triangle and as such;

∠4 = 180 - 2(∠3)

∠4 = 180 - 2(18)

∠4 = 180 - 36

∠4 = 144°

∠2 = 180 - ∠4 (because sum of angles on a straight line is 180°)

∠2 = 180 - 144

∠2 = 36°

Like it was done for angle ∠4 above;

∠1 = (180 - 36)/2

∠1 = 144/2

∠1 = 72°

Answer:

x=12

Step-by-step explanation:

Complementary angles add up to 90 degrees. 90-66=24. 24 divided by 2 is 12.

Answer:

option second 145 is right answer

Answer:

145 degrees

Step-by-step explanation:

< A = 95°

< B + 130° = 180° ( being linear pair )

< B  = 180° - 130°

<B = 50°

< D = < A + < B ( Exterior angle of a triangle is equal to the sum of two opposite interior angles )

< D = 95° + 50°

     = 145°

Answer:

It could be two unique triangles (the 7 inch length could be either of the two nonincluded sides.)

Answer:

B

Step-by-step explanation:

There is a 1/4 probability of getting an A out of a bag with letter MATH

For B) There are two A's our of 8 letters is ADMIRALS.

2/8 is the same as 1/4

The answer is B

A) is wrong because that 1/6

C) is wrong because that's 1/8

D) is wrong because that's 2/9

Answer:

B

Step-by-step explanation:

Probability of finding A in a word =  number of A / number of letters in that word

Probability of finding A in MATH = 1/4

A. Probability of finding A in BECAME = 1/6

B. Probability of finding A in ADMIRALS = 2/8 = 1/4

C. Probability of finding A in USERNAME  = 1/8

D. Probability of finding A in AFTERMATH = 2/9

So we have a match with option B

Step-by-step explanation:

The two numbers that sum to -6 and have a product of 12 are -3 ± √3i and -3 ± √3i respectively.

A numerical data is also referred to as a quantitative data and it can be defined as a data set that is primarily expressed in numbers (numerals) only. This ultimately implies that, a numerical data simply refers to a type of data set consisting of numbers (numerals) rather than words.

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

In order to solve this word problem, we would assign variables to the unknown numbers and then translate the word problem into algebraic equation as follows:

Let the two unknown numbers be x and y.

Translating the word problem into an algebraic equation, we have;

Sum: x + y = -6     .....equation 1.

Product: xy = 12       ....equation 2.

From equation 1, we have:

x = -6 - y

Substituting equation 3 into equation 2, we have:

(-6 - y)y = 12

-6y - y² = 12

y² + 6y + 12 = 0

Solving the quadratic equation, we have:

y = -3 ± √3i

For the value of x, we have:

x = -6 - y

x = -6 - (-3 ± √3i)

x = -6 + 3 ± √3i

x = -3 ± √3i

Answer:

49[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

I'm going to assume the number on the right side of the equation is 5.5, just to make things easier.

Now, to begin to solve this, first isolate the variable.

1/8y - 2/3 = 5 1/2

We do this by adding 2/3 to both sides.

1/8y = 5 1/2 + 2/3

Now, we just wipe off the coefficient that is stuck to the variable by dividing both sides by 1/8, which can be easier done by multiplying by the reciprocal (I converted the mixed number into an improper fraction before solving to facilitate the process).

y = (37/6) · 8

y = 296/6

y = 49 2/6 = 49 1/3
