Use Cavalieri’s Principle to calculate the exact volume of an oblique cylinder with a radius of 15 meters and a height of 12 meters.​

Answers

Answer:

2700pi [tex]m^{3}[/tex]

Step-by-step explanation:

The radius of cylinder is 15 meters and the height is 12 meters.

The volume of cylinder is

V = [tex]\pi r^{2} h[/tex]

Where, r is radius and h is height.

Substitute r = 15 and h = 12 in the volume formula.

V = [tex]\pi (15)^{2} (12)[/tex]

V = 2700[tex]\pi[/tex]

The volume of the cylinder is 2700[tex]\pi[/tex] m³.

Answer:

the answer should be 2700pi

Answer:

on flipping a coin, we either get a heads or a tails and both the events are equally likely. So the probablity of getting a tails is 1/2.

Now

On rolling a die, we can get 6 possible outcomes(1,2,3,4,5,6)

But the favourable outcomes (an even number) are only 3. So the probablity of getting an even number is 3/6=1/2

In case. we have 2 events that need to occur together, we simply need to multiply their individual probablities to get the probablity of getting both the events together

So our required answer is

p(even number)× p(tails)= 1/2 × 1/2 = 1/4

Solve the equation. Start Fraction y minus 5 over 3 End Fraction= 1 A. –2 B. 8 C. 18 D. 6

Answers

Answer:

B. 8

Step-by-step explanation:

Start Fraction y minus 5 over 3 End Fraction= 1

This statement above is written Mathematically as:

y - 5/3 = 1

We solve the Equation below

Step 1

y - 5/3 = 1

We cross Multiply

y - 5 = 3 × 1

y - 5 = 3

Step 2

Add 5 to both sides

y - 5 = 3

y - 5 + 5 = 3 + 5

y = 8

f(-1) = -2

f(0) = 0

f(4) = 8

Step-by-step explanation:

f(x) = 2x

f(-1) = 2(-1)

f(0) = 2(0)

=> 0

f(4) = 2(4)

In what ways do you think a cracked hard-boiled egg might serve as a model for the spatial distribution of earthquake data and the three models of plate interactions?

Answers

Answer:

- the shell is related to the egg as its outer layer just the same way the lithosphere is related to the Earth as its solid outer layer also called tectonic plate;

- the yolk is related to the egg as the centre layer just the same way the core is related to the Earth as its centre layer.

- The egg white is related to the egg as the middle layer just the same way the mantle is the middle layer of the earth

Step-by-step explanation:

A conceptual model of the relative thicknesses of the Lithosphere can be presented by measuring a simple hard-boiled egg.

The hard-boiled egg serves as a scale model for the zones of the Earth.

Now, in comparison to the earth, let's note the following;

- the shell is related to the egg as its outer layer just the same way the lithosphere is related to the Earth as its solid outer layer also called tectonic plate;

- the yolk is related to the egg as the centre layer just the same way the core is related to the Earth as its centre layer.

- The egg white is related to the egg as the middle layer just the same way the mantle is the middle layer of the earth

These comparative similarities gives us the strong idea that the lithosphere

is considered as a thin shell.

Medicare would like to test if the average monthly rate for one-bedroom assisted-living facility is different from $3,300. Suppose that you collect sample information and, based on the hypothesis test, determine that the z test statistic is equal to 1.98 while the critical value of z is 2.05. How would you state the conclusion?

Answers

Answer:

We fail to reject our null hypothesis and conclude that there is not sufficient evidence to conclude that the average monthly rate for one-bedroom assisted-living facility is different from $3,300.

Step-by-step explanation:

We are given that critical value of z=2.05

z test statistic=1.98

As we are testing that whether the the average monthly rate for one-bedroom assisted-living facility is different from $3,300, so this leads to two tailed hypothesis test as hypothesis are

Null hypothesis:μ=3300

Alternative hypothesis:μ≠3300.

The critical region in case of two tailed hypothesis test is

[tex]|z|>z_{\frac{\alpha }{2} }[/tex]

1.98>2.05 (which is not true)

So, the test statistic don't lie in rejection region, thus we don't reject our null hypothesis and conclude that there is insufficient evidence to conclude that the average monthly rate for one-bedroom assisted-living facility is different from $3,300.

A. {}
B. {0}

Answers

Answer:

I'd say the answer is C

Answer: Choice A.  { }

This is the empty set with nothing inside it. Another way to write the empty set is to use the symbol [tex]\varnothing[/tex]

The set { 0 } is not the empty set because 0 is inside it, making it nonempty. A set like {1,2,3} does not contain 0, so there's no way {0} can be a subset.

Use the drop-down menu to complete the sentence.But Kircher's ideas about the hieroglyphs themselves were even farther off the mark than those of Horapollo. Looking at a certain group of symbols which actually stood for the name of a pharaoh Kircher let his imagination run wild.
