The average number of viewers over the two weeks are 3.75 X 10^6

A tv show had 4.4 x 10^6 viewers in the first week

and 3.1 x 10^6 viewers in the second week.

What is average number ?

This is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers.

To find the average number of viewers over the two weeks

Remove the decimal point.

4.4 x 10^6 write like this 4400000

Similarly, 3.1 x 10^6 write like this 3100000

Now, Solving the question

Therefore, the average will be

4400000 + 3100000

= 7500000/2

=3750000

=3.75 X 10^6

and3.75 x 10^6

Thus , the average number of viewers over the two week 3.75 x 10^6

Which are the solutions of the quadratic equation? x2 = –5x – 3 –5, 0 StartFraction negative 5 minus StartRoot 13 EndRoot Over 2

boyakko [2]

<u>Given</u>:

The quadratic equation is $x^{2}=-5 x-3$

We need to determine the solutions of the quadratic equation.

<u>Solution</u>:

Let us solve the equation to determine the value of x.

Adding both sides of the equation by 5x and 3, we get;

$x^{2}+5 x+3=0$

The solution of the equation can be determined using quadratic formula.

Thus, we get;

$x=\frac{-5 \pm \sqrt{5^{2}-4 \cdot 1 \cdot 3}}{2 \cdot 1}$

$x=\frac{-5 \pm \sqrt{25-12}}{2 }$

$x=\frac{-5 \pm \sqrt{13}}{2 }$

Thus, the two roots of the equation are $x=\frac{-5 + \sqrt{13}}{2 }$ and $x=\frac{-5- \sqrt{13}}{2 }$

Hence, the solutions of the equation are $x=\frac{-5 + \sqrt{13}}{2 }$ and $x=\frac{-5- \sqrt{13}}{2 }$

Find number a and k so that x-2 is afactor<br>OF F(x)=x4-2ax tax-<br>X+k and F(-1)=3

Slav-nsk [51]

Question:

Find numbers a and k so that x-2 is a factor of

$f(x)=x^4-2ax^3+ax^2- x+k$

and

$f(-1)=3$

Answer:

$k = -2$ and $a=1$

Step-by-step explanation:

Given

$f(x)=x^4-2ax^3+ax^2- x+k$

$Factor:\ x - 4$

$f(-1)=3$

Required

Find a and k

For $f(-1)=3$

Substitute -1 for x

$f(x)=x^4-2ax^3+ax^2- x+k$

$f(-1) = (-1)^4 - 2a *(-1)^3 + a*(-1)^2 - (-1) + k$

$f(-1) = 1 - 2a *-1 + a*1 +1 + k$

$f(-1) = 1 +2a + a +1 + k$

$f(-1) = 2 +3a + k$

Substitute 3 for f(-1)

$3 = 2 +3a + k$

Collect Like Terms

$3 - 2 = 3a + k$

$1 = 3a + k$

Also:

If $x - 2$ is a factor, then

$f(2) = 0$

Substitute 2 for x and 0 for f(x)

$f(x)=x^4-2ax^3+ax^2- x+k$

$0 = 2^4 - 2a * 2^3 + a * 2^2 - 2 + k$

$0 = 16 - 2a * 8 + a * 4 - 2 + k$

$0 = 16 - 16a + 4a - 2 + k$

$0 = 16 - 12a - 2 + k$

Collect Like Terms

$2 - 16 = - 12a + k$

$-14 = k - 12a$

$k = 12a - 14$

Substitute 12a - 14 for k in $1 = 3a + k$

$1 = 3a + 12a - 14$

$1 = 15a - 14$

Collect Like Terms

$15a = 1 + 14$

$15a = 15$

Solve for a

$a = \frac{15}{15}$

$a=1$

Substitute 1 for a in $k = 12a - 14$

$k = 12 * 1 - 14$

$k = 12 - 14$

$k = -2$

V=pi r^2 h solve for pi<br><br>please help asap<br>will mark brainliest

kogti [31]

Answer:

$\pi=\frac{v}{hr^2}$

Step-by-step explanation:

So we have:

$v=\pi r^2h$

And we want to solve for π.

First, divide both sides by h:

$\frac{v}{h}=\pi r^2$

Now, divide both sides again by r²:

$\pi=\frac{v}{hr^2}$

And this is our answer :)

Use a proportion to estimate each population. (Please solve both questions, thank you) (I’ll reward you with brainliest :)

hammer [34]

Answer:

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

<em>Step 1. (The capture) Capture a sample total counted =958, and them back tagged counted=38,total tagged=56 </em>

<em>The idea is to estimate the proportion p = m/N of tagged =102. </em>

<em>Step 2. (The recapture) After everything has settled down, capture a new sample of n fish. Count the number of tagged fish. Suppose that k of them are tagged. </em>

<em>It is reasonable that, k/n would be a good estimante for p = m/N. </em>

<em>Accordingly, for an estimate N of N, se solve the equation m/N= k/n. </em>
