The point slope form of the eqaution of the line that passes through (-5,-1) and (10, -7) is y+7= -2/5 (x - 10) what is the stan

stira [4]

Answer:

Step-by-step explanation:

The standard form of an equation of a line:

$Ax+By=C$

We have the equation in point-slope form:

$y+7=-\dfrac{2}{5}(x-10)$

Convert it to the standard form:

$y+7=-\dfrac{2}{5}(x-10)$ multiply both sides by 5

$5y+35=-2(x-10)$ use the distributive property a(b + c) = ab + ac

$5y+35=(-2)(x)+(-2)(-10)$

$5y+35=-2x+20$ subtract 35 from both sides

$5y=-2x-15$ add 2x to both sides

$2x+5y=-15$

A market research team compiled the following discrete probability distribution, where X represents the number of automobiles ow

rodikova [14]

Answer:

The standard deviation of X is 0.7

Step-by-step explanation:

We are given the following distribution:

x: 0 1 2 3

P(x): 0.3 0.5 0.2 0.4

We have to find the standard deviation of X.

Formula:

$E(x) = \displaystyle\sum x_iP(x_i)\\\\E(x) =0(0.3) + 1(0.5) + 2(0.2) + 3(0.4)\\\\E(x) = 2.1\\\\E(x^2) = \displaystyle\sum x_i^2P(x_i)\\\\E(x^2) =0(0.3) + 1(0.5) + 4(0.2) + 9(0.4)\\\\E(x^2) = 4.9\\\\Var(x) = E(x^2) - (E(x))^2 = 4.9-(2.1)^2 = 0.49\\\\\sigma(x) = \sqrt{Var(x)} =\sqrt{0.49} = 0.7$

Thus, the standard deviation of X is 0.7
