Answer:
20
Step-by-step explanation:
sin(28) sin(x)
---------- = -----------
7 5
sin(28)* 5 = 7sin(x)
---------------------------
7
sin(28) * 5
---------------- = sin(x)
7
You have to seperate sin from (x). When you do that, it becomes inverse (sin^-1).
sin(28) * 5
sin^-1 (------------------) = x
7
Imput that into you calculator, and you should get 19.59302173 (20 to the nearest degree)
Hope this helps.
Answer:
two dots: (0, -7), (1, -3)
and it's the line
Step-by-step explanation:
just try x=0, g(x)=-7
and x=1, g(x)=-3
Answer:
50%.
Step-by-step explanation:
Calculate the z scores
z score = n - m / d where n = given value , m = mean and d = standard deviation.
So for a pressure of 8.1
z1 = 8.1-8.7/02 = -3
z2 = 8.8-8.7/0,2 = 0
So from the Standard Normal Distribution tables the required percentage
= 100 - 0.00135 - 50
= 49.9999
