what is the probability of rolling a number less or equal to a 6 when rolling a six-sided number cube

1 answer:

6 0

There are six numbers that can come up when the dice is rolled
the sample space is{ 1 2 3 4 5 6}
hence p(no. <= 6) = 6/6 =1

Find the perimeter of a polygon with sides 11ft 7ft 18ft 22ft 14ft and 23.5ft

allsm [11]

Perimeter of a polygon is equal to sum of all sides of the polygon

Sides of the polygons are 11 ft, 7 ft, 18 ft, 22 ft, 14 ft and 23.5 ft

Sum of all sides of the polygon is given by = 11 ft + 7 ft + 18 ft + 22 ft + 14 ft + 23.5 ft

= 95.5 ft

Perimeter of a polygon = 95.5 ft

Hope this helps..!!

Thank you :)

A store opens at 8am. From 8 until 10 customers arrive at a Poisson rate of four an hour. Between 10 and 12, they arrive at a Po

SVETLANKA909090 [29]

Answer:

The probability distribution of the number of customers that enter the store on a given day is:

$P(x=k)=\frac{57^ke^{-57}}{k!}$

Step-by-step explanation:

To calculate a parameter for the given day, we have to calculate what is the average arrival rate for the day.

This can be done with the data given:

1) From 10 to 12, 8 arrival/hour: 16 expected arrivals in this period

2) From 12 to 2, 8 to 12 arrival/hour (average: 10 arrivals): 20 expected arrivals in this period.

3) From 2 to 5, from 10 to 4 arrival/hour (average: 7 arrivals): 21 expected arrivals in this period.

The total expected arrivals in a day are: 16+20+21=57 arrivals/day.

Then, the probability distribution of the number of customers that enter the store on a given day is:

$P(x=k)=\frac{57^ke^{-57}}{k!}$

klio [65]

Answer:

10π feet, or about 31.42 feet

Step-by-step explanation:

Diameter = 2 times radius, so the radius is 5 feet.

The question is asking us for the circumference - the distance around the circle. Plug our radius into the formula.

C = 2πr

C = 2π(5)

<u>C = 10π feet = about 31.42 feet</u>
