Answer:

V = 113.04

Step-by-step explanation:

Volume of a sphere:

V = 4/3πr³

V = 4/3(3.14)3³

V = 4/3(3.14)27

V = 113.04

A show is on Friday, Saturday and Sunday

Gwar [14]

Answer:

270 tickets are sold for the Sunday show.

Step-by-step explanation:

Given:

Two-fifth of the total tickets are sold for the Saturday show.

Tickets sold for the Saturday show = 240

Three times as many tickets are sold for the Sunday show as for the Friday show. This means that tickets sold for Sunday show is three times that for Friday.

Let the tickets sold for Friday show be 'x'. Therefore, tickets sold for the Sunday show is given as 3 times of 'x' = $3x$

Total tickets sold = Sum of all tickets sold on Friday, Saturday and Sunday.

Total tickets sold = $x+3x+240$

Total tickets sold = $4x+240$

Now, as per question, two-fifth of the total tickets are sold for Saturday show and ticket sold on Saturday is 240. So,

$\frac{2}{5}\times(4x+240)=240\\\\8x+480=240\times5\\\\8x=1200-480\\\\8x=720\\\\x=\frac{720}{8}=90$

Therefore, tickets sold for the Sunday show = $3x=3\times90=270$

Hence, 270 tickets are sold for the Sunday show.

Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area is 5.8 per year. a. Find t

maw [93]

Answer:

a. 0.098

b. 4.41

c. Yes, it does.

Step-by-step explanation:

The Poisson distribution's equation is:

P(x) = (nˣ*e⁻ⁿ)/x!

where P is the probability, n is mean number, and x the number of the event happens, so:

$P(3) = \frac{5.8^3*e^{-5.8}}{3!}$

P(3) = 0.098

For 45 years, the years that are expected to have 3 hurricanes are

P(3) * 45 = 0.098*45 = 4.41

Yes, it does. The Poisson distribution works well because the observed value of the number of years that 3 hurricanes occur is 45-year period is very close to the calculated value.
