What is the range function of the function f(x) =2+1 given the domain D=(-1,0,1,2)

Write a linear equation in Slope-Intercept Form for a line that goes through the

Kitty [74]

Answer:

y = -2x -9

Step-by-step explanation:

<h2><u>in order to solve this question you have to do the following : </u></h2>

1. find the midpoint of the coordinates given

2. find the gradient of the line

3. make the equation

<h3><em><u>STEP : The midpoint </u></em></h3>

formula of the midpoint is

$\frac{x2 + x1}{2} , \frac{y2 + y1}{2}$

now place the values in the equation :

$\frac{-4 +-2}{2} , \frac{-5 + -1 }{2}$

midpoint = ( -3 , -3)

<h3><em><u>STEP 2 : The gradient </u></em></h3>

formula of finding the gradient

$\frac{y2-y1}{x2-x1}$

insert the values in the equation:

$\frac{-5-(-1)}{-2-(-4)}$

= $\frac{-4}{2} = -2$

gradient = -2

<h3><em><u>STEP 3: Form the equation </u></em></h3>

use the formula of the equation :

$(Y - y1) = m( X - x1)$

now make use of the gradient(m) and the midpoints and insert into the equation

(y-(-3)) = -2(x -(-3))

hence

y+3 = -2 (x +3)

y= -2x -6 -3

Svetach [21]

Answer:

A. P=0.4013

B. P=0.9884

C. P=0.3222

Step-by-step explanation:

We can model this with a binomial random variable.

The sample size is n=10.

The probability is p=0.05 for scrap and p=0.05+0.15=0.20 for degraded or scrap.

The probability of having k scrap gears in the sample is:

$P(x=k) = \dbinom{n}{k} p^{k}(1-p)^{n-k}\\\\\\P(x=k) = \dbinom{10}{k} 0.05^{k} 0.95^{10-k}\\\\\\$

The probability that one or more is scrap can be calculated as 100% less the probability that no one is scrap:

$P(x\geq1)=1-P(x=0)\\\\\\P(x=0) = \dbinom{10}{0} p^{0}(1-p)^{10}=1*1*0.5987=0.5987\\\\\\P(x\geq1)=1-0.5987=0.4013$

The probability that 8 or more are not scrap is equal to the probability of having 2 or less that are scrap:

$P(x\leq2)=P(x=0)+P(x=1)+P(x=2)\\\\\\P(x=0) = \dbinom{10}{0} p^{0}(1-p)^{10}=1*1*0.5987=0.5987\\\\\\P(x=1) = \dbinom{10}{1} p^{1}(1-p)^{9}=10*0.05*0.6302=0.3151\\\\\\P(x=2) = \dbinom{10}{2} p^{2}(1-p)^{8}=45*0.0025*0.6634=0.0746\\\\\\P(x\leq2)=0.5987+0.3151+0.0746=0.9884$

The probability that more than two are degraded or scrap (p=0.2) is calculated as:

$P(x>2)=1-P(x\leq2)=1-(P(x=0)+P(x=1)+P(x=2))\\\\\\P(x=0) = \dbinom{10}{0} p^{0}(1-p)^{10}=1*1*0.1074=0.1074\\\\\\P(x=1) = \dbinom{10}{1} p^{1}(1-p)^{9}=10*0.2*0.1342=0.2684\\\\\\P(x=2) = \dbinom{10}{2} p^{2}(1-p)^{8}=45*0.04*0.1678=0.3020\\\\\\P(x>2)=1-(0.1074+0.2684+0.3020)=1-0.6778=0.3222$

What the value of x plz

Gwar [14]

Well, the answer to this question is 55 degrees.
In this whole line intercept, the total number of degrees is 360 degrees and if 55 plus 55 equals to 110, then to solve the missing two angles, we can just subtract 110 from 360 which equals to 250 and lastly, we have to divide 250 by 2 which is 125.
