Answer:

76 square feet

Step-by-step explanation:

surface area = 2(wl + hl + hw)      w=width     h=height       l=length

surface area = 2(5*4 + 2*4 + 2*5)

surface area = 2(20 + 8 + 10)

surface area = 2(38)

surface area = 76 square feet

Restless Leg Syndrome and Fibromyalgia
Anna11 [10]

Answer:

The probability that a person with restless leg syndrome has fibromyalgia is 0.183.

Step-by-step explanation:

Denote the events as follows:

<em>F</em> = a person with fibromyalgia

<em>R</em> = a person having restless leg syndrome

The information provided is as follows:

P (R | F) = 0.33

P (R | F') = 0.03

P (F) = 0.02

Consider the tree diagram attached below.

Compute the probability that a person with restless leg syndrome has fibromyalgia as follows:

P(F|R)=\frac{P(R|F)P(F)}{P(R|F)P(F)+P(R|F')P(F')}

            =\frac{(0.33\times 0.02)}{(0.33\times 0.02)+(0.03\times 0.98)}\\\\=\frac{0.0066}{0.0066+0.0294}\\\\=0.183333\\\\\approx 0.183

Thus, the probability that a person with restless leg syndrome has fibromyalgia is 0.183.

What is the slope-intercept form 10x-7y=-8
Dafna1 [17]

Answer:

Step-by-step explanation:

Slope intercept form: y = mx +b

10x - 7y = -8

      -7y = - 10x - 8

Divide the equation by (-7)

\dfrac{-7y}{-7}=\dfrac{-10x}{-7} +\dfrac{-8}{-7}\\\\\\y =\dfrac{10}{7}x+\dfrac{8}{7}

-6x+5&gt;-1 what is the solution to the inequality?.
andrey2020 [161]

Answer:

the solution set is: x < 1

Step-by-step explanation:

Given that:

-6x+5>-1

We have to find solution for x so by simplifying:

Subtracting 5 from both sides we get:

-6x+5 - 5>-1  - 5

Both 5s on left side will be cancelled out:

-6x > -6

Dividing both sides by -6 will change the sign of inequality:

-6x/-6 < -6/-6

x < 1

So the solution set is: x < 1

i hope it will help you!
