The mean GPA is greater than 2.75.

<h3>What is GPA?</h3>
  • A grade point average is a figure that represents the average of the final grades obtained in courses over time.
  • A student's grade point average, sometimes known as a GPA, is computed by adding all accumulated final grades and dividing the total by the number of grades granted.

To find the GPA:

  • GPA is calculated and could be utilized by the college to tell choices, which include the subsequent educational progression.
  • Divide the total range of grade factors earned with the aid of the total number of letter-graded units undertaken.
  • Mean GPA = total/50
  • = 2.75.

Therefore, the mean GPA is greater than 2.75.

A county has a population density of 257 people per square mile. The county population is 4288. What is the area of this county?
ladessa [460]

Answer:

The area of the country is 17 square miles

Step-by-step explanation:

To calculate the population density of the country. We employ the use of a mathematical formula. This can easily be obtained from the units of the density

The population density = Population of the country/area of the country

Since we are to calculate the area of the country, the equation becomes

Area of country = Population of country/population density of country

Area of country = 4288/257

Area of country = 16.68 square mile

To the nearest square mile, the Area of the country = 17 square mile

A campus deli serves 101 customers over its busy lunch period from 11:30 am to 1:30 pm. A quick count of the number of customers
iogann1982 [59]

Answer:

21.38 minutes

Step-by-step explanation:

the total number served = 101

teh number of hours that is spent in serving from 11.30 to 1.30 = 2 hours

Lq = average number of those that are in line = 18 customers

from here we are to find the flow rate

= \frac{total served}{service hour}

= 101/2 = 50.5

the average time in waiting =

Lq/flow rate

= 18/50.5

= 0.3564 hours

convert to minutes = 0.3564 * 60 minutes

= 21.38 minutes
