Example 2: smoking and asthma
health officials in milwaukee, wisconsin, were concerned about teenagers with asthma. people with asthma often have difficulty with normal breathing. in a local research study,
researchers collected data on the incidence of asthma among students enrolled in a milwaukee public high school.
students in the high school completed a survey that was used to begin this research. based on this survey, the probability of a randomly selected student at this high school
having asthma was found to be 0.193. students were also asked if they had at least one family member living in their house who smoked. the probability of a randomly selected
student having at least one member in his (or her) household who smoked was reported to be 0.421.

what is the your question?

that one look

step-by-step explanation:

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
