Answer:
Step-by-step explanation:
So you can use the special formula for 30-60-90 triangle or you can use the whole Soh Cah Toa thing.
I honestly prefer trig. so a is the opposite side of the 30 deg and 12 is the hyp. This should scream sine to you since sine goes with opposite/hypotenuse.
sin(30 deg)=a/12
Multiply both sides by 12
giving a=12 sin(30)
Type into calculator unless you know your unit circle well.
a=6
58=y=39
(subtract 39 from both sides)
58-39=y
(simplify 58-39 to 19)
19=y
(switch sides)
y=19

Step-by-step explanation:
You have to use the rule of three
Answer:
The answer is "96.864 ml".
Step-by-step explanation:
In this question, the formula of .
( where X is the mean, t is the coefficient, and s is the mean difference error)
As a result, only 2.5% of containers might include less than 100 ml of volume, its trust coefficient could indeed be used in accordance with 95%, which is .
And it can take to have been the full value the standard infinite:
Consequently, if the standard error is , a similar amount should be used to fill
