Find the equation of the line passing through the points -2x+1 (8,2)

Harrizon [31]

The line that passes through (-2, 1) and (8, 2) is:

y = (1/10)*x + 12/10

<h3>How to find the equation of the line?</h3>

I assume you want to find the equation of the line that passes through (-2, 1) and (8, 2).

A general linear equation is written as:

y = a*x + b

If the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope can be written as:

$a = \frac{y_2 - y_1}{x_2 - x_1}$

In this case, we know that it passes through (-2, 1) and (8, 2), then:

$a = \frac{2 - 1}{8 - (-2)} = 1/10$

Then the line is:

y = (1/10)*x + b

To find the value of b, we use one of the given points, for example if we use (8, 2), it means that when x = 8, we must have y = 2.

2 = (1/10)*8 + b

2 - 8/10 = b

20/10 - 8/10 = b

12/10 = b

Then the linear equation is:

y = (1/10)*x + 12/10

A poll reported that 66 percent of adults were satisfied woth the job the major airlines were doing. Suppose 25 adults are selec

777dan777 [17]

Answer:

A)Option D

B)P(X = 15) = 0.1325

Step-by-step explanation:

A) From the question, the information given follows binomial distribution because there are two mutually exclusive outcomes for each trial, there is a fixed number of trials. The outcome of one trial does not affect the outcome of another, and the probability of success is the same for each trial.

So option D is correct.

B) From the question, we are told that the poll reported that 66 percent of adults were satisfied with the job. Thus, probability is; p = 0.66

Let X be the number of adults satisfied with the job. Since 25 are selected,

Thus;

P(X = 15) = C(25, 15) * (0.66)^(15) * (1 - 0.66)^(25 - 15)

P(X = 15) = 3268760 × 0.00196407937 × 0.00002064378

P(X = 15) = 0.1325

This equation shows how the total number of pieces Lamar has learned depends on the number of weeks he has taken piano lessons.

Dominik [7]

Answer:

19 weeks

Step-by-step explanation:

Given equation:

P = w

Where,

w = the number of weeks he has taken piano lessons

p = the total number of pieces he has learned

how many weeks of piano lessons will Lamar need before he will be able to play a total of 19 pieces?

Find w when p = 19

P = w

p = 19

Since P = w

19 = w

Therefore,

w = 19

Lamar need 19 weeks before he will be able to play a total of 19 pieces

How would you Evaluate. 5⋅4 ^0

solniwko [45]

It is understood that 5.4^0 is the number 5.4 raised to the power zero.

There is a rule for this: any number raised to the power zero is 1.

So, 5.4 ^ 0 = 1.

You can show that any number raised to the power of zero is 1 using this:

A^0 = (A)^(m - m) = [A^m] / [A^m]

Given that the numerator and the numerator of that fraction are equals the result is 1.
