(I may give brainliest) The roof of a lean-to-garden shed has a gradient of 0.35.find the height?

UkoKoshka [18]

Answer: 2.325 meters

Step-by-step explanation:

The roof of a lean-to-garden shed has a gradient of 0.35.find the height....they have given the base as 1.5m and a shorter height 1.8m its like a house

-------

It sounds like you have a right triangle with base = 1.5,

----

Use a proportion to get:

(height of that triangle)/1.5 = 35/100

height of that triangle = 1.5*0.35 = 0.5250

-----

greater height of the lean-to = 1.8 + 0.5250 = 2.325 meters

People with restless leg syndrome have a strong urge to move their legs to stop uncomfortable sensations. People with fibromyalg

USPshnik [31]

Answer:

0.1833

Step-by-step explanation:

Given:

% of people with fibromyalgia = 2%

Probability of having a restless leg syndrome for people with fibromyalgia = 0.33

Probability of having a restless leg syndrome for people without fibromyalgia = 0.03

Take F as event of having fibromyalgia

Take R as event of having restless leg

Required:

Find the probability that a person with restless leg syndrome has fibromyalgia.

To find the probability that a person with restless leg syndrome has fibromyalgia, we have: P(F/R)

$P(F/R) = \frac{P(F n R)}{P(R)}$

$P(F/R) =\frac{P(R/F) * P(F)}{P(R/F) * P(F) + P(R/F^c) * P(F^c)}$

Where,

P(R/F) = 0.33

P(F) = 2% = 0.02

P(R/F') = 0.03

P(F') = 1 - 0.02 = 0.98

Therefore,

$P(F/R) = \frac{0.33 * 0.02}{0.33*0.02 + 0.03*0.98}$

= 0.1833

Probability a person with restless leg syndrome has fibromyalgia = 0.1833
