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).

Answer:

[tex]y = 250 + \frac{10x}{3}[/tex]

Step-by-step explanation:

Given

[tex]Daily\ Wages = 250[/tex]

[tex]Additional = 10[/tex] for every 3

Required

Determine the function that represents Jessie's daily earnings:

From the question, we have that:

y = earnings

x = phones

If for 3 phones, he gets 10.

i.e.:

3 pieces = 10

then

[tex]1\ pieces = \frac{10}{3}[/tex] ----- By dividing both sides by 3

and

[tex]x\ pieces = \frac{10x}{3}[/tex] ----- By multiplying both sides by x

The above expression represents the additional earnings for x phones

So, daily earnings y is calculated as :

[tex]y = Daily\ Wages + Additional\ Earnings[/tex]

[tex]y = 250 + \frac{10x}{3}[/tex]

The function representing his daily earning (y) as a function of the number  of cell phones sold (x) is y = (10/3)x + 250.

A linear equation is given  by:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept.

Let x represent the number of cell phones sold and y represent the daily earnings.

Since he has a daily wage of 250 pesos, hence b = 250. Also he makes additional  10 pesos for every 3 pieces of cell phone sold, hence m = 10/3.

The equation becomes:

y = (10/3)x + 250

Therefore the function representing his daily earning (y) as a function of the number  of cell phones sold (x) is y = (10/3)x + 250

Step-by-step explanation:

As, 1 crate = 200 apples

5 crates = 200+200+200+200+200 = 1,000

So, 5 crates = 200 x 5 = 1,000

5 crates = 1,000 apples

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]

======================================================

Explanation:

The exponent rules are

The expression on the right hand side simplifies to c^(-1). We add the exponents to get this. So we're using rule 1 mentioned above.

We'll keep this in mind for later.

------------------

On the left hand side (c^5)^4 becomes c^(20) because we multiply the exponents (rule 3)

Then (c^20)/(c^x) becomes c^(20-x). We subtract exponents here (rule 2).

------------------

After using those exponent rules, the original equation turns into

c^(20-x) = c^(-1)

The bases are both c, so the exponents must be equal

20-x = -1

-x = -1-20

-x = -21

x = 21

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

Step-by-step explanation:

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.
