2 different shapes with an area of 6 square units and perimeter of 12 units

1 answer:

4 0

Square and rectangle

Other example:
To understand the given problem use the formular of area.

Hence, area is the length and width of the object in unit squared.

Mathematically expressing, a = l x w
Since a = l x w 
a = lw unit squared

Given:
Area = 112 cm2

Square root of Area = Square root of 112 cm2
Area = 10.58 cm

Check:
Area = (10.58 cm)^2
Area = 111.9 / 112

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

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:

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

Answer:

1)7 2/8

2) 4 1/2

3) 7 2/4

4) 4 3/5

5) 7 1/9

6) 3 2/8

I will add more answers once I add this answer.

Step-by-step explanation: 1) you divide the top number by 8 then you will get 7 with a remainder of 2. 7 is the whole number and 2 will be on top of the fraction. do the same with all other problems.

Find the derivative of f(x) = 8x^2 + 11x at x = 7.

sleet_krkn [62]

Thank you for posting your question here at brainly. Feel free to ask more questions.

f′(x)=2∗(8x(2−1))+1∗11x(1−1)

which is

f′(x)=16x+11

then let x = 7 gives us

f′(7)=123

Hope my answer would be a great help for you.
