Answer:

The volume of the cylinder is 25.12

Step-by-step explanation:

The width is the diameter in the circle of the base

radius = half of diameter

r = 2/2 = 1

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 8

π = 3.14

r = radius = 1

v = (π * r²) * h

we replace the unknowns with the values we know

v = (3.14 * (1)²) * 8

v = (3.14 * 1) * 8

v =3.14 * 8

v = 25.12

The volume of the cylinder is 25.12

Solve the system of equations.<br> - 3x + 2y = 56<br> - 5 - 2y = 24

Oduvanchick [21]

Awnser

y=13

Step-by-step explanation:

-3x+2y=56

-5x-2y=24

so first we want to get rid of one variable, in this example we dont need to multiply because the y's cancel out

so we have

-8x=80

x=-10

now plug in x into an original equation

-3(-10)+2y=56

2y=26

y=13

hope that helps

How does a computer drawing program compare to using a compass and straightedge?

notsponge [240]

A computer drawing program generally has more steps compared to using a compass and straightedge, although not by much. In a computer drawing program, you can erase an error within a click of a button, compared to having to manually perfect and erase your work when using a compass and straightedge. Also, you immediately have access to an online drawing program as long as you have Internet connection and a computer compared to having to go out and buy a new compass and straightedge. Other than that, they're generally the same despite being different mediums.

Hope this helps!

Assume a normal distribution. From the Baltimore facility, 145 samples were obtained and compared with a sample of 128 from the

Evgesh-ka [11]

Answer:

Hello your question has some missing part below is the missing part

The mean hours per week and standard deviations for middle management who had been with the organizations for approximately the same length of time were: Baltimore facility, Burlington facility Mean 52.5 Mean 39.7

Standard deviation 19.7 Standard Deviation 8.9Using this data, complete the following:

State your hypothesis and conduct a hypothesis testing using a significance of 0.10.

answer : We will reject the Null hypothesis

Step-by-step explanation:

μ1 = mean working hours for Baltimore facility

μ2 = mean working hours for Burlington facility

Hence the Hypothesis are :

H0 : μ1 = μ2

Ha : μ1 > μ2

<em>Next: Conduct a hypothesis testing </em>

we will apply Z - testing attached below is the hypothesis testing

n1 = 145 , X1 = 52.5 , δ1 = 19.7 ( Baltimore )

n2 = 128, X2 = 39.7 , δ2 = 8.9 ( Burlington )

Given the parametric equations, x = 2t + 5 and y = 3t^2 - 1, find the point on the graph at time, t = 4.

Tpy6a [65]

Answer: (13, 47)

The expression t = 4 means that 4 units of time have come off the clock (possibly 4 seconds). Plug this value into each equation given for x and y

x = 2*t + 5 = 2*4 + 5 = 8 + 5 = 13

y = 3*t^2 - 1 = 3*4^2 - 1 = 3*16 - 1 = 48 - 1 = 47

In short, if t = 4 then it leads to x = 13 and y = 47 at the same time. These x and y values pair up to get the final answer (13,47)
