use the point–slope formula to write an equation of the line that passes through(-5, -16 )and has a slope of m = 3 . Write the a

scoray [572]

Answer:

y + 16 = 3(x + 5)

Step-by-step explanation:

When you write an equation in point-slope form, you only need two things: a point and a slope.

Given:

point: (-5, -16)

slope (m): 3

The standard point-slope equation is

y - y₁ = m(x - x₁)

Plug in what you know.

y - (-16) = 3(x - (-5))

Simplify.

y + 16 = 3(x + 5)

This is your equation.

A random variable follows the continuous uniform distribution between 160 and 340. Calculate the following quantities for the di

Firlakuza [10]

Answer:

a) 0.3889

b) 0.5

c) 0.8333

d) The mean is 250 and the standard deviation is 51.96.

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability of finding a value of X higher than x is:

$P(X > x) = 1 - \frac{x - a}{b-a}$

The probability of finding a value of X between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The mean and the standard deviation are, respectively:

$M = \frac{a+b}{2}$

$S = \sqrt{\frac{b-a}^{2}{12}}$

A random variable follows the continuous uniform distribution between 160 and 340.

This means that $a = 160, b = 340$

$P(220 \leq X \leq 290) = \frac{290 - 220}{340 - 160} = 0.3889$

$P(160 \leq X \leq 250) = \frac{250 - 160}{340 - 160} = 0.5$

$P(X > 190) = 1 - \frac{190 - 160}{340 - 160} = 0.8333$

$M = \frac{160 + 340}{2} = 250$

$S = \sqrt{\frac{340 - 160}^{2}{12}} = 51.96$

The mean is 250 and the standard deviation is 51.96.
