If EF - 3x - 11, FG = 4x-10, and EG - 28, find the values of x, EF, and FG. The drawing is not to scale.

Gnom [1K]

Answer:

Part 1) $x=7$

Part 2) $EF=10\ units$

Part 3) $FG=18\ units$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the value of x

we know that

$EG=EF+FG$ ---> by addition segment postulate

we have

$EG=28\ units\\EF=3x-11\\FG=4x-10$

substitute

$28=(3x-11)+(4x-10)$

solve for x

$28=7x-21$

$7x=28+21$

$7x=491$

$x=7$

step 2

Find the value of EF

$EF=(3x-11)$

substitute the value of x

$EF=3(7)-11=10\ units$

step 3

Find the value of FG

$FG=(4x-10)$

substitute the value of x

$FG=4(7)-10=18\ units$

Help pls! Brainliest!

blagie [28]

Answer:

y =-3000x +12000

Step-by-step explanation:

answer is

1) 12000 is the constant therefore when the number of hours is 0 the tickets are 12000

2) the number of tickets (y) are reducing by 3000 for each hour(x). thus the coefficient of variable x should be -3000 (negative because it is reducing)

Help guys<br> I realy need help <br> I will report you if you give me the wrong answer

telo118 [61]

Answer:

the Answer is 150x + 12100 ≤ 26500

Step-by-step explanation:

The max weight is 26500 so the weight would have to be the same or less than 26500 (≤)

There is already 12100 killograms on the sipping containter so that is why you have + 12100

and you have 150x because x is the number of 150-kilogram crates

and for as many crates you have to multiply by the weight.

What is F(3) if F(x) = x3– 2x2 + 3x –12?

wariber [46]

Step-by-step explanation:

Simply input 3 for x in the equation.

$x^{3} -2x^2+3x-12\\(3)^{3} -2(3)^2+3(3)-12\\27-18+9-12\\Final answer = 6$

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.
