Suppose that weight of adolescents is being studied by a health organization and that the accompanying tables describes the probability distribution for three randomly selected​ adolescents, where x is the number who are considered morbidly obese. Is it significant to have no obese subjects among three randomly selected​ adolescents?

Answers

Answer:

hello your question lacks some information attached below is the complete question

answer : NO

Step-by-step explanation:

Determine the probability of not selecting an obese subject in 3 trials

= P ( not obese in 3 randomly selected ) = ( 1 - 0.111 )^3

= 0.703

The probability > 0.05

hence it is insignificant therefore the answer is NO

If sin 0º = 0, then csc 0°=
(check image)

Answers

Answer:

Step-by-step explanation:

sin(0) = 0/2

sin(30) = 1/2

sin(45) = [tex]\sqrt{2}[/tex]/2

sin(60) = [tex]\sqrt{3}[/tex]/2

sin(90) = [tex]\sqrt{4}[/tex]/2

cos(90) = 0/2

cos(60) = 1/2

cos(45) = [tex]\sqrt{2}[/tex]/2

cos(30) = [tex]\sqrt{3}[/tex]/2

cos(0) = [tex]\sqrt{4}[/tex]/2

notice that sin and cos repeat,   but in reverse

Solve the inequality.
x + 23 < 37
Group of answer choices

x < 60

x < 14

x < 37

x < 23

Answers

Answer:

x = 14

x + 23 < 37 ( move constant to right-hand side and change its sign)

x<37-23 ( subtract numbers)

x < 14

The answer is x=14.

Solving Steps:
First you need to move the constant to the right-hand side and change its sign.
Do this by subtracting 23 from both sides.

Then do 37-23 to get 14

So your answer is x=14
