Answer:
She sells 4 loaves of bread
Step-by-step explanation:
Lets explain how to solve the problem
→ A baker uses cups of flour to make bread
→ She uses cups of flour to make each loaf
From these information we can find the number of loaves of bread
she can make
∵ There are cups of flour
∵ Each loaf of bread needs cups of flour
∴ The number of loaves = ÷
To divide two mixed numbers make them improper fractions and
change the division sign to multiplication sign and reciprocal the
fraction after the division sign
∵ =
∴ =
∵ =
∴ =
∴ The number of loaves = ×
∴ The number of loaves = 6
<em>She can make 6 loaves</em>
→ The baker sells of the loaves of bread that she makes
→ We need to find the number of loves of bread she sells
∵ She sells of the loaves
∵ There are 6 loves
∴ The number of loaves she sells = 6 × = 4
<em>She sells 4 loaves of bread</em>
Answer:
And we can find this probability using the z table and we got:
Step-by-step explanation:
Let X the random variable that represent the thickness of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the z table and we got:
