Dear Mathee2, you can do 1/10+1 8/10≈2 and 1/20+1 19/20≈2. Note: you said fractions, so did you want the fractions to be mixed numbers or improper fractions?
I don’t get what you are asking ? make a number like and draw the fraction 1/5
Answer:
Use the normal distribution if the population standard deviation is known.
Use the student's t distribution when the population standard deviation is unknown.
Explanation:
A mound-shaped distribution refers to the normal distribution.
A good sample size for testing against the normal distribution should be
n >= 30.
The condition for the sample size is satisfied.
However, we are not given the population standard deviation, therefore it is assumed to be unknown.
Therefore the student's t distribution should be used.
Answer:
Step-by-step explanation:
Let equal sides of an isosceles triangle = a inches
Base = 
inches
Perimeter = 32 inches
a + a + = 32
Subtract 2 from both sides
a = 12 inches
base = 
= 6 + 2
Base = 8 inches
