Graph a line with a slope of -3that contains the point (4,-2)

Answer:

25

Step-by-step explanation:

you can write this equation as 20 ÷ [tex]\frac{4}{5}[/tex]

so change the division sign to multiplication by flipping the divisor ( [tex]\frac{4}{5}[/tex] )

this means you now have 20 x [tex]\frac{5}{4}[/tex]

so you can simplify 20 and 4, this makes the 4 into a 1 and the 20 into a 5

you now have 5 x [tex]\frac{5}{1}[/tex]

this is the same thing as 5 x 5

multiply it, and you can see that the answer is 25

Answer: 36

Step-by-step explanation:

=========================================================

Work Shown:

The triangles are similar, which means the corresponding angles are congruent. In this case, we can say angle K = angle Q. Note how K and Q are the second letters of JKL and PQR respectively. The order matters.

Because angle K = angle Q, we can use information from triangle JKL to get information about triangle PQR.

We can say the following:

cos(angle) = adjacent/hypotenuse

cos(K) = LK/JK

cos(K) = 5/13

cos(Q) = 5/13 ... plug in K = Q

Answer:the answer is D y-2= 1/5(x+3)

Step-by-step explanation:I took the test

y-2=-1/5(x+3) is the  point-slope form of the equation below that represents the line that passes through the points (-3, 2) and (2, 1).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given two points are (-3, 2) and (2, 1)

m=1-2/2+3

=-1/5

So slope is -1/5.

Now let us find the point slope form

y-y₁=m(x-x₁)

y-2=-1/5(x+3)

Hence, y-2=-1/5(x+3) is the  point-slope form of the equation below that represents the line that passes through the points (-3, 2) and (2, 1).

Answer:

10a-16b+23

Step-by-step explanation:

First, you see what terms are alike. Then you add those like terms. For example with this expression, you add 7b+b+8b, resulting in 16b. If you are confused by the single b variable standing alone, there is basically a 1 in front of it, so you add it as 1b. 11 and 12 are like terms, for they don't have any variables attached to them. 10a stands alone because no other terms have an a variable. The simplified expression is 10a-16b+23.

Your welcome <3

The simplified value of the expression 10a - 7b + 11 + 8b - b - 12 is 1a - 1.

Given Expression:

10a-7b+11+8b-b-12

To simplify expression, first solve the like terms as

10a-7b+11+8b-b-12

= 10a -7b + 8b - b - 12 + 11

Now, -7b + 8b - b = -7b + 7b = 0

and, -12 + 11 = -1

Substituting the simplified value in 10a-7b+11+8b-b-12 gives

= 10a + 0 - 1

= 10a - 1

Answer:

a. positive.

Step-by-step explanation:

Matching and discordant pairs are used to describe the relationship between pairs of observations. To calculate matched and discordant pairs, data is treated as ordinal values. Therefore these are suitable for your application. The number of concordant and discordant pairs is used in Kendall's tau calculations, whose purpose is to determine the relationship among two ordinal variables.

If the direction of the classifications is the same, the pairs are concordant.

A pair of observations is discordant, suppose the subject being with an increased value on one variable is lower on the other.

SO; When discordant pairs exceed concordant pairs in a P-Q relationship, Kendall's tau reports a(n) positive association between the variables under study.

ii. y=x+6

iii. y=-2x-6

iiii. y=-4x+3

iiiii. y=4x-3

Step-by-step explanation:

You can find the slope of the line by putting y2-y1/x2-x1

All you have to do is choose 2 points. Y2 is the second number y and x2 is the second number x. Y1 is the first number y and X1 is the first number X. To find y-intercept you look on the table and see where X is 0 and Y is any number that is the y-int. For example 5 there is no X=0 on the table so you put it in the point slope formula which is y-y1=m(x-x1) where you use the points from the slope. You multiply m to x and m to x1 where you will end up with y-y1=mx+mx1 then you add the y1 to mx1 where you will get the y intercept

Answer: m<C= 31

Step-by-step explanation:

To find m<C: Since the triangles are equal, we know that (4x+10) is equal to 90. Then when you put them equal to each other and solve for x you get X=20. Then all you have to do is plug that x value (20) into the equation for the angle of C (x+11). Then you get that C=31 degrees.

Answer:

22

Step-by-step explanation:

Answer:

We have a system of equations with no solutions.

One of the equations is:

x + y = 5.

Isolating y in one side of the equation, we get:

y = 5 - x

And the other equation has an y-intercept of -2, the equation can be written as:

y = a*x - 2.

Then the system will be:

y = -1*x + 5

y = a*x - 2

The solution of a system of equations is a point where the graphs of both functions intersect.

Then if both of these lines are parallel, the lines will never intersect, then the second equation must be parallel to the first one.

And two lines are parallel if they have the same slope.

Then the other equation will be:

y = -x - 2

The value of the expression is 0.0009.

We have,

To explain the process of evaluating (0.03)², we need to understand the concept of exponentiation and how it applies to decimal numbers.

When we raise a number to the power of 2 (or square it), we are essentially multiplying the number by itself.

In this case, we are squaring the decimal number 0.03.

To calculate (0.03)², we multiply 0.03 by itself:

= 0.03 x 0.03

= 0.0009

In decimal form,

0.03 squared is equal to 0.0009.

This process follows the general rule of exponentiation, where raising a number to a power means multiplying the base number by itself the specified number of times.

In this case, we square 0.03 by multiplying it by itself once, resulting in 0.0009.

Thus,

The value of the expression is 0.0009.

Answer:

The probability that 121 or more Americans in the survey are afraid to fly is 0.1335.

Step-by-step explanation:

Let X denote the number of Americans afraid to fly.

The proportion of Americans afraid to fly is, p = 0.10/

A random sample of n = 1100 Americans are selected.

The random variable X follows a Binomial distribution with parameters n = 1100 and p = 0.10.

But the sample selected is too large and the probability of success is close to 0.50.

So a Normal approximation to binomial can be applied to approximate the distribution of X if the following conditions are satisfied:

1. np ≥ 10

2. n(1 - p) ≥ 10

Check the conditions as follows:

 [tex]np=1100\times 0.10=110>10\\\\n(1-p)=1100\times (1-0.10)=990>10[/tex]

Thus, a Normal approximation to binomial can be applied.

So,  [tex]X\sim N(np,\ np(1-p))[/tex]

Compute the probability that 121 or more Americans in the survey are afraid to fly as follows:

[tex]P(X\geq 121)=P(\frac{X-np}{\sqrt{np(1-p)}}>\frac{121-110}{\sqrt{99}})\\\\=P(Z>1.11)\\\\=1-P(Z<1.11)\\\\=1-0.86650\\\\=0.1335[/tex]

Thus, the probability that 121 or more Americans in the survey are afraid to fly is 0.1335.

The probability is 24.609%

The mathematical subject of probability deals with the outcomes of random events. The term "probability" refers to the possibility or chance of an outcome. It clarifies the likelihood of a particular occurrence. We use phrases like "It will probably rain today," "he will probably pass the test," "there is very little chance of getting a storm tonight," and "most probably the price of onion will go high again" all the time.

Given a coin is tossed 9 times, and to find the probability of exact four heads,

the probability for condition given by  binomial probability ⁿCₓ[(p)ˣ(q)ⁿ⁻ˣ]

where p is probability of tail = 1/2 (favorable outcome)

q is probability of head = 1/2: (1 - p)

n = total outcome = 9

x = 4

ⁿCₓ[(p)ⁿ(q)ⁿ⁻ˣ] = ⁹C₄[(1/2)⁴(1/2)⁵]

= [tex]\frac{9!}{4!(9 - 4)!}[/tex] [1/16 x 1/32]

= [tex]\frac{9 x 8 x7 x 6 x 5!}{4! x 5!}[/tex](512)

126/512 = 0.24609

= 24.609%

Hence the probability, to the nearest thousandth is 24.609%.
