cylinder with radius of 5 and height of 4 surface area

Answer:

?

Step-by-step explanation:

Answer:

(0,-4)

(3,0)

Step-by-step explanation:

Let start at the orgin.

This is a linear equation since the equation is in the form of

[tex]y = mx + b[/tex]

where m is the slope and b is the y intercept.

Since we starting at the orgin, and b is our y intercept.

Our first point is

(0,-4).

since the slope is 4/3.

We would rise 4 from the y value and run 3 to the x value.

In other words, to find your second point, go up 4 units from the first point and move to the right 3 units.

So our next point is at

(3,0).

U can continously go up 4 units and move 3 units to the right to find other points.

Answer:

A) Airplane A has a lesser median

Step-by-step explanation:

If you look at the photo you see both airplane A and airplane B and if you were to line them up

airplane A=3

airplane B=4 ½  

so clearly airplane A would have a lesser median than airplane B

Answer:

y=9

Step-by-step explanation:

5(y-10)=-5

5y-50=-5

+50 +50

5y=45

/5 /5

y=9

Answer:

Sale Price = $29.05 (answer). This means the cost of the item to you is $29.05. You will pay $29.05 for a item with original price of $35 when discounted 17%. In this example, if you buy an item at $35 with 17% discount, you will pay 35 - 5.95 = 29.05 dollars

Answer:

6

Step-by-step explanation:

6 is in the middle with 2 numbers on each side so it is the medium

Answer:

hello

Step-by-step explanation:

Answer:

Here, nice to meet you! I'm Avocadorable! lolz ;)

Answer:

A.  We know that this was an experiment rather than an observational study because treatments were administered, with the first group receiving the experimental drug, the second group receiving a placebo, and the third group receiving no treatment."

B. The factors are the variables.  The independent variable was group three that received no treatment, while the dependent variables were the first and second groups that received some treatments.  Another variable is the change in blood pressure recorded at the end of the period.

The levels refer to the different treatments that were administered to the three groups: experimental drug, placebo, and no treatment.

C. The principles of experimental design are Randomization, Repetition, and Control.  We are not aware of how the participants were chosen and this experiment was not replicated in the scenario.  We can affirm that there is Control because the three groups were not given the same treatment.

Step-by-step explanation:

In an observation, the researcher does not attempt to change any variables.  She simply observes and then records her observations.  In an experimental study, the researcher creates a control group and, also at least, one testable group.  The purpose is to compare the control group and the testable group.

So first you need to find the area of the building site which is:

length x width

39.5m x 32.5m

= 1283.75[tex]m^{2}[/tex]

We know that one square meter costs 185.50 euros.

1[tex]m^{2}[/tex] = 185.50 euros

1283.75[tex]m^{2}[/tex] = 238135.625 euros

I'm not exactly that familiar with euros but I'm pretty sure that euros don't have 3 numbers after the point so the two nearest numbers are 238134.86 and 238135.86.

sorry if this is wrong, but I hope it helps, if the euros part is wrong please correct me thanks!

Answer:

20 students offered both physics and biology.

Step-by-step explanation:

n(Total) = 50

n(Physics) = 40

n(Biology) = 30

Let n(Physics and Biology) = x

n(Physics only) = 40 -x

n(Biology only) = 30 - x

40 - x + 30 - x + x = 50

70 - x = 50

x = 20

Answer:

33.51 in^2

Step-by-step explanation:

Find the area of the circle:

A = πr^2

A = π * 8^2

A = 64π = 201.06 in^2

Find the area of the 60 deg slice:

A * 60/360 = 33.51 in^2

Answer:

She needs to sample 189 trees.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

The standard deviation of the population is 70 peaches per tree.

This means that [tex]\sigma = 70[/tex]

How many trees does she need to sample to obtain an average accurate to within 10 peaches per tree?

She needs to sample n trees.

n is found when M = 10. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]10 = 1.96\frac{70}{\sqrt{n}}[/tex]

[tex]10\sqrt{n} = 1.96*70[/tex]

Dividing both sides by 10:

[tex]\sqrt{n} = 1.96*7[/tex]

[tex](\sqrt{n})^2 = (1.96*7)^2[/tex]

[tex]n = 188.2[/tex]

Rounding up:

She needs to sample 189 trees.

Answer:

it would be

18 x 5x = 915

solve the equation

18 x 5 = 90

90x = 915

divide by 90

Answer:

20579.52628

Step-by-step explanation:

4/3 pi(r^3)

4/3 pi x 17 x 17 x 17

= 20579.52628

Answer:

20579.5

Step-by-step explanation:

The formula for The volume of a Sphere is 4/3 pi r^3

so it would be 4/3pi *  4913

4.19666666....* 4913 which would equal to  20.579.53333333333 or 20579.5

Step-by-step explanation:

Vertical angles are angles formed when two straight lines intersects at a point forming vertical angles that share the same vertex and are directly opposite to each other.

In the diagram given, we have the following pairs of vertical angles:

<7 and <9

<8 and <10

<12 and <14

<11 and <13

Therefore there are 4 pairs of vertical angles

Answer

$199.8

Explanation:

Find the total amount of money he had in the begining. It says that he can spend $18 on each student. He has 18 students so you would multiply that by the $18 he can spend which gives a total of $324 then you subtract the total cost of the calculators from it which then gives you $199.8

Answer:

2 more sides.

Step-by-step explanation:

Decagon = 10 sides

Octagon = 8 sides

The prefix Octa means 8 sides

example : Octa is in Octapus; and octopus have 8 legs or tentacles.

Answer:

2 sides.

Step-by-step explanation:

Correct me if I'm wrong but a decogon has 10 sides and an ogtagon has 8 sides so it might be 2.
