Answer:

-1

Step-by-step explanation:

We can use the formula to find slope

(y2-y1) / (x2-x1)

y1 is the first Y coordinate in the first pair

y2 is the second one in the first pair

X1 is the first X coordinate in the frst pair

x2 is the second one In the second pair.

so if we put it together it’d look liek this

(5- (-) 2) / (-4 - 3)

5+2 / -4 + -3

7/-7

or -1

Answer:

6 + 2x² = 20

2x² = 20 - 6

2x² = 14

x² = 14 ÷ 2

x² = 7

x = √7

x = 2.64

Answer:

If it's multiple choice, I'd say B and D. If it's only one, those are the ones I'd narrow it down to.

Step-by-step explanation:

All you have to do is imagine the question's answers as a statistic. With A, you can't say "There are 56% theaters in my city." So that's out. C is the same, you cant say "The students in my class watch 47% movies in a month." Also out. Sorry if this answer is incorrect, but that's your best bet.

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:

Let’s use the slope formula to calculate the slope of a line, using just the coordinates of two points. The line passes through the points (1, 4) and (-1, 8). Let’s call the point (1, 4) point 1, and the point (-1, 8) point 2. That means x1 = 1, y1 = 4, x2 = -1, and y2 = 8.

Example

Points

Coordinates

(1, 4)

x1 = 1

y1 = 4

(-1, 8)

x2 = -1

y2 = 8

The slope formula is . When we put the coordinates into the formula, we get the equation . This reduces to m = -2. The slope of the line is -2.

It is important to realize that it doesn’t matter which point is designated as 1 and which is 2. We could have called (-1, 8) point 1, and (1, 4) point 2. In that case, putting the coordinates into the slope formula produces the equation . Once again, that simplifies to m = -2. That’s the same slope as before.

Step-by-step explanation:

Slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: . This simple equation is called the slope formula.

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:

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:

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
