The number of visitors to the homepage of an online magazine in the year 2005 is 3527

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more number and variables.

Let y represent the total number of visitors x years since 2000. Hence:

y = 1100.74x - 1976.47

In the year 2005 (x = 5):

y = 1100.74(5) - 1976.47 = 3527.23

The number of visitors to the homepage of an online magazine in the year 2005 is 3527

Given a cone 10 feet tall with a diameter of 10 feet, determine the radius of the smaller cone created when a horizontal plane p

11111nata11111 [884]

Answer:

r=3 ft

Step-by-step explanation:

it is similarity of two triangles

one

perpendicular side=10 ft

base=10/2=5 ft

second

perpendicular side=10-4=6 ft

Base r=?

$\frac{r}{5}=\frac{6}{10}\\r= \frac{6}{10} \times 5=3~ft$

Evaluate ,where e is the solid that lies between the cylinders x^2+y^2=1 and x^2+y^2=16, above the xy-plane, and below the plane

MA_775_DIABLO [31]

Assuming you're just computing the volume, i.e.

$\displaystyle\iiint_E\mathrm dV$

we should convert to cylindrical coordinates first, setting

$\begin{cases}x=r\cos\theta\\y=r\sin\theta\\z=\zeta\end{cases}$

so that the volume is given by

$\displaystyle\iiint_E\mathrm dx\,\mathrm dy\,\mathrm dz=\int_{\theta=0}^{\theta=2\pi}\int_{r=1}^{r=4}\int_{\zeta=0}^{\zeta=r\sin\theta+4}r\,\mathrm d\zeta\,\mathrm dr\,\mathrm d\theta$

which has a value of $60\pi$ .

1. Hoover Dam spans the Colorado

Alona [7]

BEST estimate of this amount is $2(10^{7})$ . Correct option A. 2 x 10^7 .

<u>Step-by-step explanation:</u>

Here we have , Hoover Dam spans the Colorado River on the Nevada-Arizona state line. For its construction, the federal government purchased 21,670,000 pounds of gates and valves. We need to find BEST estimate of this amount . Let's find out:

21,670,000 pounds

⇒ 21,670,000 pounds

⇒ $21,670,000$

⇒ $2167(10^{4})$

⇒ $2.167(10^{3})(10^{4})$

⇒ $2.167(10^{3+4})$

⇒ $2.167(10^{7})$

Now, Rounding of 2.167 we get 2 ,So

⇒ $2(10^{7})$

Hence , BEST estimate of this amount is $2(10^{7})$ . Correct option A. 2 x 10^7 .

Find the following list of data calculate a demean be the maid in and see the mouth or mothers of the numbers from

Lelechka [254]

Given:

A fair die is rolled.

It pays off $10 for 6, $7 for a 5, $4 for a 4 and no payoff otherwise.

To find:

The expected winning for this game.

Solution:

If a die is rolled then the possible outcomes are 1, 2, 3, 4, 5, 6.

The probability of getting a 6 is:

$P(6)=\dfrac{1}{6}$

The probability of getting a 5 is:

$P(5)=\dfrac{1}{6}$

The probability of getting a 4 is:

$P(4)=\dfrac{1}{6}$

The probability of getting other numbers (1,2,3) is:

$P(\text{Otherwise})=\dfrac{3}{6}$

$P(\text{Otherwise})=\dfrac{1}{2}$

Now, find the sum of product of payoff and their corresponding probabilities to find the expected winning for this game.

$E(x)=10\times P(6)+7\times P(5)+4\times P(4)+0\times P(\text{Otherwise})$

$E(x)=10\times \dfrac{1}{6}+7\times \dfrac{1}{6}+4\times \dfrac{1}{6}+0\times \dfrac{1}{2}$

$E(x)=\dfrac{10}{6}+\dfrac{7}{6}+\dfrac{4}{6}+0$

On further simplification, we get

$E(x)=\dfrac{10+7+4}{6}$

$E(x)=\dfrac{21}{6}$

$E(x)=3.5$

Hence, the expected winnings for this game are $3.50.
