Answer:

36/9 = 72/18

Step-by-step explanation:

36 times 2 is 72

Since the number on top was multiplied by two so is the number on the bottom

9 times 2 is 18

Therefore, 36/9 = 72/18

The volume between the cone and the sphere is approximately 23.55 cubic units.

We are given that;

[tex]X= sqrt(y^2 + z^2)[/tex]

[tex]x^2 + y^2 + z^2 = 16.[/tex]

Now,

To find the volume between the cone and the sphere, we can use a triple integral in spherical coordinates.

The cone corresponds to the equation [tex]$\rho = 2\cos(\phi)$[/tex], where [tex]$\rho$[/tex] is the radial distance, [tex]$\phi$[/tex]is the polar angle, and [tex]$\theta$[/tex] is the azimuthal angle. The sphere corresponds to the equation [tex]$\rho = 4$[/tex]. The limits of integration are:

[tex]$0 \leq \theta \leq 2\pi$$0 \leq \phi \leq \frac{\pi}{4}$$2\cos(\phi) \leq \rho \leq 4$[/tex]

The volume element in spherical coordinates is [tex]$\rho^2\sin(\phi)d\rho d\phi d\theta$[/tex]

Therefore, the volume is:

[tex]$V = \int_{0}^{2\pi}\int_{0}^{\frac{\pi}{4}}\int_{2\cos(\phi)}^{4}\rho^2\sin(\phi)d\rho d\phi d\theta$[/tex]

Evaluating this integral, we get:

[tex]$V = \frac{32}{3}\pi - 8\sqrt{2}\pi + 16\pi$[/tex]

Therefore, by volume of cone the answer will be 23.55 cubic units.

Answer:

45 cookies

Step-by-step explanation:

Use a unit rate.

With a unit rate, we find the number of cookies that are baked using 1 scoop.

(30 cookies)/(6 scoops) = 5 cookies/scoop

The rate of 30 cookies to 6 scoops is the same as the unit rate of 5 cookies/scoop.

Now we multiply the unit rate by 9 scoops.

9 scoops * 5 cookies/scoop = 45 cookies

Answer: 45 cookies

Answer:

The 95% confidence interval for the average number of years until the first major repair is (3.1, 3.5).

Step-by-step explanation:

The (1 - α)% confidence interval for the average using the finite correction factor is:

[tex]CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}\cdot\sqrt{\frac{N-n}{N-1}}[/tex]

The information provided is:

[tex]N=1500\\n=183\\\sigma=1.47\\\bar x=3.3[/tex]

The critical value of z for 95% confidence level is,

z = 1.96

Compute the 95% confidence interval for the average number of years until the first major repair as follows:

[tex]CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}\cdot\sqrt{\frac{N-n}{N-1}}[/tex]

     [tex]=3.3\pm 1.96\times\frac{1.47}{\sqrt{183}}\times\sqrt{\frac{1500-183}{1500-1}}\\\\=3.3\pm 0.19964\\\\=(3.10036, 3.49964)\\\\\approx (3.1, 3.5)[/tex]

Thus, the 95% confidence interval for the average number of years until the first major repair is (3.1, 3.5).

Width : Length

Perimeter = 2* width + 2*length

Ratio becomes:

Width : Length

4 : 6

Total units = 4 + 6 = 10

Perimeter = 40

Answer: Width is 8 ft and Length is 12 ft.

Answer:

The correct option is d

Step-by-step explanation:

From the question we are told that

    The sample size is  n = 64

    The mean is  [tex]\= x = 320[/tex]

    The standard deviation is [tex]\sigma = 120[/tex]

Generally the standard error of the mean is mathematically represented as  

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

=>    [tex]\sigma_x = \frac{120}{ \sqrt{64} }[/tex]

=>    [tex]\sigma_x =15[/tex]

The value of A4 for the given condition if a1=6 and an=2an-1 is 48.

A1 = 6 means a(1) == 6

This is the first term of the sequence. Then you have the “rule” or the “closed form” of the sequence,

which is: an = 2an - 1 for n>1,

Should be written like this: a(n) == 2 × (an - 1) for n>1.

Now,  It says that for any n>1, you should do this:

a(2) - that is the 2nd term is:

a(2) == 2 * (an - 1).

But (an -1) means “the term before this one”, which is the first term.

So, a(2) ==2 × 6 == 12, which is the 2nd term.

The 3rd term will be: a(3) == 2 × 12 = 24.

And the 4th term will be:

a(4) == 2 × 24 = 48.

So,the sequence will be:

6 , 12, 24, 48.

Thus, If a1=6 and an=2an-1, then the value of A4 under the indicated circumstance is 48.

The product of given binomial and trinomial is:

[tex]8x^3-34x^2-27x-9[/tex]

Step-by-step explanation:

A binomial is a polynomial with 2 terms and trinomial is a term with 3 terms.

Given

[tex](4x+3)\\and\\(2x^2-5x-3)[/tex]

Distributive property can be used to find the result.

Writing mathematically

[tex](4x+3)(2x^2-5x-3)\\= 4x(2x^2-5x-3)+3(2x^2-5x-3)\\= 8x^3-40x^2-12x+6x^2-15x-9[/tex]

Combining alike terms

[tex]= 8x^3-40x^2+6x^2-12x-15x-9\\= 8x^2-34x^2-27x-9[/tex]

Hence,

The product of given binomial and trinomial is:

Step-by-step explanation:

well, 4 or below go down 5 and above go up so go from there

Answer:

p=2(L+W)

p=304

L=40+w

p=2(40+w+w) ,40+w is the value of L

304=2(40+2w)

304/2=2(40+2w)/2 divided both side by 2

152=40+2w

152-40=2w

112=2w

112/2=2w/2

w=56

and L =40+w

40+56=96.

so L=96 and W=56.
