the volume of the box is L x W x H so it should be 7x5x4=140
First you find the zeros/x-intercepts using the factors already given in the inequality.
Therefore we make our solution using the interval notation.
45 adult t shirts were sold approximately
btw the total amount sold doesn't seem accurate it seems off by about 5 dollars
Answer:
the probability of a rating that is between 200 and 275 is 0.4332
Step-by-step explanation:
Given the data in the question;
if an applicant is randomly selected, the probability of a rating that is between 200 and 275
mean μ = 200
standard deviation σ = 50
P( 200 < X < 275 ) = P( X-μ / σ < x-μ / σ < X-μ / σ )
P( 200 < X < 275 ) = P( 200-200 / 50 < x-μ / σ < 275-200 / 50 )
= P( 0/50 < Z < 75/50 )
= P( 0.00 < Z < 1.50 )
P(Z < 1.50) - P(Z < 0.0)
from the standard normal table
P(Z < 1.50) = 0.9332
P(Z < 0.0) = 0.5000
so
P( 200 < X < 275 ) = 0.9332 - 0.5000
P( 200 < X < 275 ) = 0.4332
Therefore, the probability of a rating that is between 200 and 275 is 0.4332
Answer:
(r-7)(r+2)
Step-by-step explanation:
First, let's look at the -14. Possible factors for that number are (-2, 7) (2, -7) (1, -14) and (-1, 14).
Now, let's look at the -5. How can we make -5 with the pairs that we just found?
The only possible way is 2 and -7 (added together equals -5)
