Answer:
a) 
And we can find this probability with the complement rule:
b) 
And if we use the z score we got:
Step-by-step explanation:
Let X the random variable that represent the lengths of a population, and for this case we know the distribution for X is given by:
Where 
and 
Part a
We are interested on this probability
And we can use the z score formula given by:
And using this formula we got:
And we can find this probability with the complement rule:
Part b
For this case we select a sample of n =44 and the new z score formula is given by:
And if we find the z score we got:
And if we use the z score we got:
Answer:
12

Answer:
2 1/6 hours
Step-by-step explanation:
2 1/3 + 1 1/2 + x = 6
convert all mixed numbers to improper fractions
7/3 + 3/2 + x = 6/1
change all numbers to have a common denominator
14/6 + 9/6 + x = 36/6
combine like terms
23/6 + x = 36/6
subtract 23/6 from both sides
x = 13/6
convert improper fraction to mixed number
2 1/6
Answer:
No. I don't have enough Flour to make 5 loaves of bread.
From the Amount of flour i had i can make 4 loaves only.
Step-by-step explanation:
Given:
Flour required for making loaves of bread = 
cups
Amount of flour i had = 8 cups
Number of loaves of bread = 
We need to find the we have enough flour to make 5 loafs of bread.
Solution:
We know that;
Amount of flour I had is equal to Flour required for making loaves of bread
framing in equation form we get;
Dividing both side by 2 we get;
Hence From the Amount of flour i had i can make 4 loaves only.
Hence I don't have enough Flour to make 5 loaves of bread.
Answer:
This is a linear function.
