Answer:

Mean = 109.364

Step-by-step explanation:

Given

Data: 147, 160, 80, 110, 121, 164, 62, 90, 76, 83, 110

Required

Calculate the mean

Mean is calculated as:

Mean = \frac{\sum x}{n}

In this case:

n = 11

So, we have:

Mean = \frac{147+ 160+ 80+ 110+ 121+ 164+ 62+ 90+ 76+ 83+ 110}{11}

Mean = \frac{1203}{11}

<em></em>Mean = 109.364<em> -- approximated</em>

Find the rational roots f(x) =3x3+ 2x2 + 3x + 6
Ann [662]

The rational roots of f(x) = 3x^3 + 2x^2 + 3x + 6 are ±(1, 2, 3, 6, 1/3, 2/3)

<h3>How to determine the rational root of the function f(x)?</h3>

The function is given as:

f(x) = 3x^3 + 2x^2 + 3x + 6

For a function P(x) such that

P(x) = ax^n +...... + b

The rational roots of the function p(x) are

Rational roots = ± Possible factors of b/Possible factors of a

In the function f(x), we have:

a = 3

b = 6

The factors of 3 and 6 are

a = 1 and 3

b = 1, 2, 3 and 6

So, we have:

Rational roots = ±(1, 2, 3, 6)/(1, 3)

Split the expression

Rational roots = ±(1, 2, 3, 6)/1 and ±(1, 2, 3, 6)/3

Evaluate the quotient

Rational roots = ±(1, 2, 3, 6, 1/3, 2/3, 1, 2)

Remove the repetition

Rational roots = ±(1, 2, 3, 6, 1/3, 2/3)

Hence, the rational roots of f(x) = 3x^3 + 2x^2 + 3x + 6 are ±(1, 2, 3, 6, 1/3, 2/3)

The complete parameters are:

The function is given as:

f(x) = 3x^3 + 2x^2 + 3x + 6

The rational roots of f(x) = 3x^3 + 2x^2 + 3x + 6 are ±(1, 2, 3, 6, 1/3, 2/3)

How to do this problem <br> 3x-2=6
sergiy2304 [10]

Answer:

x = 2.667

Step-by-step explanation:

so first you wanna isolate the x by adding 2 to both sides

3x - 2 = 6 ---> 3x = 8

then divide both sides by 3 to get the x alone

x = 8/3 = 2.667

Schaum earns (x4 + 16x) every month. His wife earns (3x4 + 11x) every
damaskus [11]

Given:

Schaum's earnings in a month = x^4+16x

His wife's earnings in a month = 3x^4+11x

Where x is the number of working days in a month.

To find:

The total earnings in a month.

Solution:

We know that,

Total earnings = Schaum earnings + His wife's earnings in a month

                       =x^4+16x+3x^4+11x

                       =(x^4+3x^4)+(16x+11x)

                       =4x^4+27x

Therefore, the correct option is A.
