Write a mathematical sentence that expresses the information given below . Use t as your variable name.Necessary type <= to m

miskamm [114]

Answer:

t + 8° > 82°

Step-by-step explanation:

Given that :

Let t = temperature when Susanne checks at 11:00

If t rises by 8 more degrees, it will break the record high temperature for that day

Record high temperature for the day = 82 degree

Hence,

Temperature at 11:00 + 8° > record high temperature for the day

t + 8° > 82°

Restless Leg Syndrome and Fibromyalgia

mixas84 [53]

Answer:

The probability that a person with restless leg syndrome has fibromyalgia is 0.1833.

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:

$P(F|R)=\frac{P(R|F)P(F)}{P(R|F)P(F)+P(R|F')P(F')}\\\\=\frac{(0.33\times 0.02)}{(0.33\times 0.02)+(0.03\times 0.98)}\\\\=0.183333\\\\\approx 0.1833$

Thus, the probability that a person with restless leg syndrome has fibromyalgia is 0.1833.

The formula for the slope of a line passing through the points (x₁, y₁) and (x₂, y₂) is m=?

Ad libitum [116K]

The formula to find the slope of a line is $\frac{y_{2} - y_{1}}{x_{2}-x_{1}}$ .

I'm not sure if my fraction looks right, so I'll add it in a separate attachment too.
