Answer:

12.73

Step-by-step explanation:

solution,

here,

Given

radius of cylindrical vase is 5 cm

A vessel can fill 1000 cm of water it means

The volume of water vase is 1000 cu.cm

According to the formula ,

Volume of cylinder is - pi * r2 * h

or, 1000= (22/7)*(5*5)*h

or, 1000= 22*25*h/7

or, 1000*7= 550h

or, 7000= 550h

or, 7000/550= h

or, 12.73 cm = h

Therefore the depth of vase is 12.73 cm

thanks a lot for this question.

I would be glad to help you! I will solve through 3 to get you started.

This is a very important concept, so it would be helpful if you learn it on your own.

C= 2* pi* r

1. The radius is 5 cm. 5 cm represents r in the equation.
C= 2* 3.14 (or pi)* 5 
Multiply it by using a calculator. 
My answer was 31.4.

Let's try the second one.
2. The diameter is 9. Have of the diameter is the radius. 
9/2= 4.5 
Plug it into the equation.
C= 2*3.14*4.5
I got 28.26

One more. 
Plug it into the equation.
C= 2*3.14*5.6
35.17 was my answer.

Make sure to add the end signs to you answer, ft, cm, meter, etc.

Let me know if you need more help.

Brainliest answer is always appreciated.

Last​ year, a person wrote 126 checks. Let the random variable x represent the number of checks he wrote in one​ day, and assume
Arisa [49]

Answer:  The mean number of checks written per​ day  =0.3452

Standard deviation=0.5875

Variance  =0.3452

Step-by-step explanation:

Given : The total number of checks wrote by person in a year = 126

Assume that the year is not a leap year.

Then  1 year = 365 days

Let the random variable x represent the number of checks he wrote in one​ day.

Then , the mean number of checks wrote by person each days id=s given by :-

\lambda=\dfrac{126}{365}\approx0.3452

Since , the distribution is Poisson distribution , then the variance must equal to the mean value i.e. \sigma^2=\lambda=0.3452

Standard deviation : \sigma=\sqrt{0.3452}=0.5875372328\approx0.5875

The graph of f(x) = 2x^2 − 3x + 5 will be translated 8 units down, producing the graph of q(x). What equation represents the new
Fed [463]

q(x=f(x-h+k

here, h=0, k=-8, so

to translate f(x) 8 units down, we have

q(x)=f(x-0)-8

=2x^2-3x+5-8

=2x^2-3x-3
