Step-by-step explanation:
Let X the random variable that represent the time required to construct and test a particular component of a population, and for this case we know the distribution for X is given by:
Where and
We want to find this probability:
And the best way to solve this problem is using the normal standard distribution and the z score given by:
Using this formula we got:
And we can find this probability with this difference:
And if we use the normal standard distribution or excel we got:
Answer:
roses and
sunflowers
Step-by-step explanation:
Since the ratio of roses to sunflowers is , we can represent how many there are of each as
and
, respectively. We know that there are
more sunflowers than roses, so we can set up the following equation to solve for
:
Solving for , we get:
(Subtract
from both sides of the equation to isolate
)
(Simplify)
(Symmetric Property of Equality)
(Divide both sides of the equation by
to get rid of
's coefficient)
(Simplify)
Therefore, since , we know that there are
roses and
sunflowers. Hope this helps!
