Answer: sinA = a/c
Explanation: Since A is the angle, b is the adjacent side and c is the hypotenuse since it is across the 90 degree point. Side a is the opposite side, sine is opposite/hypotenuse.
Answer: = -3g-4
Step-by-step explanation:
Answer:
x=y
Step-by-step explanation:
-let x be the number of tennis balls and y the number of rackets.
-We divide the number of balls by the number of rackets to find out their ratio of proportionality:

-Hence, for each one tennis ball, there is a tennis racket.
#This is a direct linear relationship and is modeled as graphed in the attachment:
Step 3 is wrong.
It should be 4/7 / 5/8
4/7 x 8/5
32/ 35
Answer: 0.8490
Step-by-step explanation:
Given : The population of lengths of aluminum-coated steel sheets is normally distributed with a mean of 30.0 inches and a standard deviation of 0.9 inches.
i.e.
and 
Let x denotes the lengths of aluminum-coated steel sheets.
Required Formula : 
For n= 36 , the probability that the average length of a sheet is between 29.82 and 30.27 inches long will be :-

∴ Required probability = 0.8490
