Answer:

Refer to Image.

3 went 0 to 5 times

2 went 6 to 10 times

3 went 11 to 15 times

1 went 16 to 20 times

3 went 21 to 25 times

Step-by-step explanation:

When making a histogram, it's good practice to first gather all the frequencies of each number.

1 - 1

3 - 1

4 - 1

6 - 1

10 - 1

11 - 2

12 - 1

16 - 1

20 - 2

22 - 1

Now that we have the total number of frequencies of each number, we can then combine the frequencies for each age range.

0 - 5:  3

6 - 10: 2

11 - 15: 3

16 - 20: 1

21 - 25: 3

The histogram shows that out of the 12 visitors.

3 went 0 to 5 times

2 went 6 to 10 times

3 went 11 to 15 times

1 went 16 to 20 times

3 went 21 to 25 times

joyville has a population of 20,750 people. its population is increasing at a rate of 2.9% each year. what is the function?
harina [27]

Answer:

Step-by-step explanation:

Since the rate is greater than 1 this is an exponential growth function of thr form

y=ar^x, where y=final value, a=initial value, r=common ratio or rate, and x=term number

In this case a=20750, r=1.029 so

y=20750(1.029)^x

Aubrey has a new art box in the shape of a rectangular prism. The box is 5  inches, by 8 inches, by 2  inches. The only thing in
umka2103 [35]
To solve this problem you must apply the proccedure shown below:
 The total volume of the art box not taken up by the eraser is:
 Vt=V(artbox)-V(eraser)

 V(eraser)=0.25 inchesx1 inchx2 inches
 V(eraser)=0.5 inches³

 V(artbox)=5 inchesx8 inchesx2 inches
 V(artbox)=80 inches³

 Vt=80 inches³-0.5 inches³
 Vt=79.5 inches³

 The answer is: 79.5 inches³

Astronomers treat the number of stars in a given volume of space as a Poisson random variable. The density in the Milky Way Gala
umka21 [38]

Answer:

a) 0.264

b) 48 cubit light-years

Step-by-step explanation:

For calculating a)  What is the probability of 3 or more stars in 16 cubic light years?

a)

λ= 1 star/16 cubic light-years

t= measure t in units of 16 cubic light years.

E(Y) = λ t = (1/16)(16) = 1 star

P(X>=2) = 1 - P(X<2)

= 1 - [e^-1 + (e^-1)(1)/1!]

= 0.264

b)

P(X≥1) = 1 - P(X=0)

= 1 - e^-μ

0.95 = 1 - e^-μ

e^-μ = 1 - 0.95

e^-μ = 0.05

ln(e^-μ) = ln(0.05)

-μ = -3

μ = 3

Therefore  3 x 16 = 48 cubic light years of space
