What’s the length of the segments variable expressions ??

maxonik [38]

Answer:

$EF=9\ units$

Step-by-step explanation:

we know that

The Trapezoid Mid-segment Theorem states that: A line connecting the midpoints of the two legs of a trapezoid is parallel to the bases, and its length is equal to half the sum of lengths of the bases

so In this problem

$EF=\frac{1}{2}[AD+BC]$

substitute the given values

$x=\frac{1}{2}[(x-6)+(2x-3)]$

$x=\frac{1}{2}[3x-9]$

$2x=(3x-9)\\3x-2x=9\\x=9$

so

$AD=x-6=9-6=3\ units$

$EF=x=9\ units$

$BC=2x-3=2(9)-3=15\ units$

Using radicals write an equivalent expression for the expression y 1/5

ruslelena [56]

Assuming yo meant $y^ \frac{1}{5}$

reemmber
$x^ \frac{m}{n}= \sqrt[n]{x^m}$

so

$y^ \frac{1}{5}= \sqrt[5]{y^1}= \sqrt[5]{y}$

The warranty for a particular system on a new car is 2 years. During which there is no limit to the number of warranty claims pe

const2013 [10]

Answer: by using Poisson distribution

The warranty for a particular system on a new car is 2 years

P(x=2)= 0.143

There is no limit to the number of warranty claims per car

P(X=0) = 0.449

Step-by-step explanation:

step:-1

A random variable X is said to follow a Poisson distribution if it assumes only non-negative values and its probability distribution is given by

P(X=x) = $\frac{e^{-w}w^{x} }{x!}$

here w>0 is called the parameter of the distribution

Step 2:- Given mean value of Poisson distribution = 0.8

The warranty for a particular system a new car is 2 years

P(X=x)=P(X=2)= $\frac{e^{-0.8}{0.8^{2} } }{2!}$

P(x=2)= 0.143

Step 3:-

Given mean value of Poisson distribution = 0.8

There is no limit to the number of warranty claims per car

P(X=x)=P(X=0)= $\frac{e^{-0.8}{0.8^{0} } }{0!}$

P(X=0) = 0.449

What is equivalent to -x/y

Blizzard [7]

14, because the percentage of -x to y is not equivalent so when u divide it, u get 14.

miskamm [114]

Answer:

No

Step-by-step explanation:

65 is closer to 0 on the number line. Therefore 65 has a lower value the 344.
