The population of a city in 2000 was 18,500 people. Since then the population has increased 4.8% every year. Determine the correct equation that would represent what the population would be in the year 2028.

Answers

Answer:

see below

Step-by-step explanation:

Consider the year 2000 to be year 0. This would make year 2028 year 8.

Population growth or decay function: [tex]A = Pe^{rt}[/tex]

where A is the final amount, P is the principal amount, r is the rate, and t is time.

[tex]A = 18,500e^{(0.048)(8)}[/tex]

This can be simplified to

[tex]A = 18,500e^{0.384}[/tex]

Hopefully this is what the question is asking!

Answer and Step-by-step explanation:

You got the triangle at front, half of 6 is 3, so then you do 4 times 3 divided by 2, which is 6.

There are 4 of those triangles, so 4 times 6 is 24.

Now, we got two rectangles on top. 5 times 12 is 60, and 60 + 60 is 120.

the bottom rectangle is 6 times 12, which is 72.

Now we add.

24 + 120 + 72 is 216

20, 18, 21, 18, 22, 24, 18, 23, 23, 24 Explain the meeting of the interquartile range as it relates to the number of students in the kindergarten classes

Answers

The interquartile range of the data-set is of 5.5, which means that the middle 50% kindergarten classes has a number of students that differ by at most 5.5.

What are the median and the quartiles of a data-set?

The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.The first quartile(Q1) is the median of the first half of the data-set, and is also the 25th percentile.The third quartile(Q3) is the median of the second half of the data-set, and is also the 75th percentile.The interquartile range(IQR) represents the middle 50% of the distribution, and is given by Q3 - Q1.

For this problem, the ordered data-set is given by:

18, 18, 18, 20, 21, 22, 23, 23, 24, 24.

There are 10 elements, hence:

The first half is 18, 18, 18, 20, which has median (18 + 18)/2, hence Q1 = 18.The second half is 23, 23, 24, 24, which has median (23 + 24)/2, hence Q3 = 23.5.

Then the IQR is:

Q3 - Q1 = 23.5 - 18 = 5.5.

The IQR is of 5.5, which means that the middle 50% kindergarten classes has a number of students that differ by at most 5.5.

hat is the surface area of a cylinder that has a volume if 785.4in3 and a radius of 5 in?


A 471.2in2
B 10in2
C 150in2
D 4712.3in2

Answers

Answer:

A. 471.2 in²

Step-by-step explanation:

Cylinder volume:

V = πr²h

Cylinder surface area:

A = 2πr(r + h)

Find h from the first equation:

h = V/(πr²) = 785.4/(3.14*5²) = 10 in

Find surface area:

A = 2π(5)(5 + 10) = 471.23 in²

Correct choice is A

Answer:

volume of cylinder=πr²h

785.4=22/7×5²×h

h=785.4×7/(22×25)=9.99=10in

Step-by-step explanation:

surface area of cylinder =2πr(r+h)=2π×5(5+10)=

471.238898038in²

A 471.2in2 is your answer.

Kiki's mother cooked a dinner that contained a total of 992 calories. She also prepared a dessert that contained a total of 846 calories. The dinner was divided into 4 equal servings. The dessert was divided into 6 equal
servings. Kiki had one serving of dinner and one serving of dessert.

Which equation could be used to solve for n, the number of calories that kiki
ate?

A. n = 992 x 4 + 846 x 6
B. n = 1,838 / 10
C. n = 992 / 4 + 846 / 6
D. n = 992 / 4 - 846 / 6

Answers

Answer: C

Step-by-step explanation:

992/4=165

846/6=141

165+141=306
