Answer:

m = -4

Step-by-step explanation:

Slope m = (y2-y1)/(x2-x1)

m = (-7 - -19)/(-2 - 1) = (-7 + 19)/(-3) = 12/-3 = -4

Which equation in slope-intercept form represents a line that passes through the point (6,−1) and is perpendicular to the line y

damaskus [11]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It is the slope of the line

b: It is the cut point with the y axis

By definition, if two lines are perpendicular then the product of their slopes is -1.

If we have: $y = 2x-7$

$m_ {1} = 2\\2 * m 2 = - 1\\m_ {2} = - \frac {1} {2}$

Thus, the equation is of the form:

$y = - \frac {1} {2} x + b$

We substitute the point:

$-1 = - \frac {1} {2} (6) + b\\-1 = - \frac {1} {2} (6) + b\\-1 = -3 + b\\-1 + 3 = b\\b = 2$

Finally, the equation is:

$y = - \frac {1} {2} x + 2$

Answer:

$y = - \frac {1} {2} x + 2$

Which of the following numbers is the sum of 82.545 and 128.580 written with the correct number of significant digits? A. 211.12

nasty-shy [4]

When we add 82.545 and 128.580 we get a total of 211.125, now the closest number to the answer is B. 211.125

<h3>Addition of Numbers</h3>

Given Data

Number one = 82.545

Number two = 128.580

Total Number = 82.545 + 128.580

Total Number = 211.125

The probability that a person has blue eyes is 16%. Three unrelated people are selected at random. a. Find the probability that

gladu [14]

Answer:

Step-by-step explanation:

All three have blue eyes.

P(1 has blue eyes) = 16/100 = 4/25

P(3 have blue eyes) = 4/25 * 4/25 * 4/25

P(3 have blue eyes ) = 64/15625

If you need the decimal answer, it is .004096

No one has blue eyes out of three

The probability for this is very large.

P(no blues) = 1 - 64/15625

P(no blues) = 15561/15625

If you need the decimal answer, it is 0.996

One has blue eyes (the other two do not).

P(1 has blue eyes) = 16/100 * 84/100*84/100

P(1 has blue eyes) = 112896/1000000

P(1 has blue eyes) = 0.112896
