Why is t distribution better than normal distribution?

Mathematics

You must use the t-distribution table when working problems when the population standard deviation (σ) is not known and the sample size is small (n<30). General Correct Rule: If σ is not known, then using t-distribution is correct. If σ is known, then using the normal distribution is correct.

Can you show me the full formula i will reward you with 10 points​
Papessa [141]

Answer:

The formula is 4x+3x+2x=180.

x= 20

a= 40

b= 80

c= 60

Step-by-step explanation:

The expression is the angle measurments equaled to 180 degrees because they all make up a straight line (180 degrees).

You then find the other angle measurments by identifying the verticle angles.

For example, 3x= 60 degrees. Therefore angle C= 60 because it is verticle to 3x

I need this answer and FAST! This is the problem: 4=8-3h
Sergio [31]
Rememeber, you can do anything to an equation as long as you do it to both sides


4=8-3h
minus 8 both sides
-4=-3h
divide both sides by -3
-4/-3=h
4/3=h
h=4/3 or about 1.333333333333333333333333333
