Answer:
sinB = 21/75
tanB = 21/22
Step-by-step explanation:
sinΦ = Height / Hypotenuse
tanΦ = Height / Base
Answer:
sin B = 7/25, tan B = 7/24
Step-by-step explanation:
sin = opposite / hypotenuse, tan = opposite / adjacent

D. 72
I gave Brainlist you ever answer first
Answer:
A. 78
Step-by-step explanation:
7 x 4 is the bottom and the bottom is the same as the top so I got 28 x 2 which is 56. 4 x 1 is one side. The other side is the same so I got 4 x 2 which is 8. 1 x 7 is the front and back. I got 7 x 2 is 14. i wrote 56 + 14 + 8 and got 78

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?
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

Fourteen percent of the town’s population are above the age of 65. If there are about
320 residents over the age of 65, then what is the town’s population?
Answer:
So if 14% are over 65, and 320 residents are over 65, then we can say that 14% of the town is 320. Then, we can divide by 14 to find 1%, which is 22.857142857 Now we can multiply this by 100 to get 2285.7142857.

Step-by-step explanation:
If sin 0º = 0, then csc 0°=
(check image)
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
the answer for your questions is in there.
