The radius of the cone that holds ice cream which has height of 4.5 inches and 1.5π cubic inches, is 1 inches.

Volume of cone is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.

The volume of the cone can be given as,

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

Here, (r) is the radius of the base of the cone and (h) is the height of the cone.

The diagram of the cone is shown, in which,

Let suppose the radius of the cone is r inches long. Thus, put the values in the above formula,

[tex]V=\dfrac{1}{3}\pi r^2h\\1.5\pi=\dfrac{1}{3}\pi r^2(4.5)\\1.5\pi\times3=\pi r^2(4.5)\\\dfrac{1.5\pi\times3}{\pi \times 4.5}= r^2\\1= r^2\\r=\sqrt{1}\\r=1\rm\; inches[/tex]

Thus, the radius of the cone that holds ice cream which has height of 4.5 inches and 1.5π cubic inches, is 1 inches.

The correct statements regarding the function are:

2. The period of the function is [tex]2\pi[/tex].

4. The amplitude of the function is 2.5.

5. The midline of the function is y = 1.5.

The amplitude of a function is half the difference between the largest and the smallest value.

In this problem, these values are of 4 and -1, hence the amplitude is:

A = (4 - (-1))/2 = 2.5.

Thus the midline is:

y = -1 + 2.5 = 4 - 1.5 = 2.5.

The period of a function is the distance between it's repetitions. Hence, for this graph, the period is of [tex]2\pi[/tex].

Answer:

Step-by-step explanation:

The sine of the other acute angle is 15/17 if the cosine of one acute angle of a right triangle is 8/17.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a cosine of one acute angle of a right triangle is 8/17.

Let's suppose the angle is α

[tex]\rm Cos\alpha = \frac{8}{17}[/tex]

As we know the cos is the ratio of adjacent to hypotenuse and Sin is the ratio of the opposite to hypotenuse.

Let's suppose the length of the hypotenuse is x units

From the Pythagoras theorem:

[tex]\rm 17^2=x^2+8^2[/tex]

x = 15 units

Now the Sin ratio:

[tex]\rm Sin\alpha = \frac{15}{17}[/tex]

Thus, the sine of the other acute angle is 15/17 if the cosine of one acute angle of a right triangle is 8/17.

Check the picture below.

Using the normal distribution, it is found that there is a 0.0571 = 5.71% probability that the total weight exceeds the maximum weight.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, we have that the parameters are given as follows:

[tex]\mu = 60, \sigma = 10, n = 10, s = \frac{10}{\sqrt{10}} = 3.1623[/tex]

The probability that the total weight exceeds the maximum weight is the probability of a sample mean above 650/10 = 65 kg, which is one subtracted by the p-value of Z when X = 65.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{65 - 60}{3.1622}[/tex]

Z = 1.58.

Z = 1.58 has a p-value of 0.9429.

1 - 0.9429 = 0.0571.

0.0571 = 5.71% probability that the total weight exceeds the maximum weight.

Step-by-step explanation:

By taking the average number of eggs for both barns, we will see that the correct option is A.

For a set of N elements {x₁, x₂, ..., xₙ} the mean is given by:

[tex]M = \frac{x_1 + x_2 + ... + x_n}{N}[/tex]

For barn 1, the set is {2, 5, 5, 6}

So the mean is:

M1 = (2 + 5 + 5 + 6)/4 = 4.5

For the barn 2, the set is {3, 6, 8, 9}

So the mean is:

M2 = (3 + 6 + 8 + 9)/4 = 6.5

Now, taking the quantity 100%(M2 - M1)/M1 we get:

100%*(6.5 - 4.5)/4.5 = 44%

So the average in barn 2 is around 50% larger than the average in barn 1. Then the correct option is A.

Answer:

24.8 ft

Step-by-step explanation:

Formula to find the volume of a sphere is :

Volume = [tex]\frac{4}{3}[/tex] π r³

Here,

r ⇒ radius

Given that,

Volume ⇒ 8000 ft³

Let us find the radius of the tank now.

Volume = [tex]\frac{4}{3}[/tex] π r³

8000 =  [tex]\frac{4}{3}[/tex] π r³

8000 =  [tex]\frac{4}{3}[/tex] × 3.14 × r³

8000 × 3 = 4 × 3.14 × r³

24000 = 12.56r³

Divide both sides by 12.56.

1910.822 = r³

∛1910.822 = r

12.40 ft = radius

And now let us find the diameter of the sphere.

d = 2r

d = 2 × 12.40

d = 24.8 ft

The diameter of the tank is 24.80 ft

Step-by-step explanation:

Given-

i.e. The volume of spherical tank = 8,000 ft^3

Now, the formula for finding volume of any spherical figure is-

Therefore, substituting value, we get

[tex]⇢8000 = \frac{4}{3} \pi {r}^{3} [/tex]

[tex]⇢8000 \times \frac{3}{4 } = \frac{22}{7} \pi {r}^{3} [/tex]

Transposing 4/3 to left hand side ,it will become 3/4 . And Here, 8000 will get cancelled by 4 leaving 2000

[tex]⇢2000 \times 3 \times \frac{7}{22} = {r}^{3} [/tex]

Similarly , On performing further calculations, we get. ..

[tex]⇢ \frac{21000}{11} = {r}^{3} [/tex]

[tex]⇢1910.822 = {r}^{3} [/tex]

[tex]⇢ \sqrt[3]{1910.822} = r[/tex]

[tex]⇢ \underline{12.40 = r}[/tex]

Thus, the radius of the tank is 12.40 ft

Now,

The diameter of the tank = 2 × radius

[tex] \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 12.40[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \: \: = 24.80[/tex]
