Jami can mow 1/6 acre in 8 minutes. If her rate is constant, can Jami mow 1 1/2 acres in one hour?

lapo4ka [179]

Time taken by Jami to mow 1/6 acres is 8 minutes=8/60=2/15 hours.

Rate at which Jami is mowing will be:

rate=(number of acres)/(time)=(1/6)/(2/15)

=1/6÷2/15

=1/6×15/2

=5/4 acres/hour

=1.25 acres/hour

From above calculations we conclude that Jami cannot mow 1.5 acres in 1 hour

svlad2 [7]

Answer:

The expected number of admissions for the fall semester is approximately 1248 students.

Step-by-step explanation:

We are given the following information in the question:

Number of Students: 1,060 1,400 1,540

Probability: 0.61 0.11 0.3

Formula:

$\text{Expectation} = E(x) = \sum xP(x)$

Expected number of admissions for the fall semester =

$E(x) = \sum xP(x)\\= (1060\times 0.61) + (1400\times 0.1) + (1540\times 0.3)\\=1248.6$

Hence, the expected number of admissions for the fall semester is approximately 1,248 students.
