Answer:

Median.

Step-by-step explanation:

Assuming the teacher is not of similar age to the students, their higher age would pull the mean higher than if the teacher were not included, where the median would not be pulled by this extreme value.

Fiesta28 [93]

Answer:

The values are evaluated below.

Step-by-step explanation:

Given function is

$-x^4-7x^3-12x^2$

We have to find the domain, range, rel max, rel min, end behaviour, increasing or decreasing intervals and zeros of polynomial.

Domain:

The domain of a function is the set of all possible values of x for the given function.

Here domain is set of all real numbers R.

Range:

The range is the resulting y-values we get after substituting all the possible x-values.From the graph we see that

The range is $-\infty$

Relative maxima and minima of a function, are the largest and smallest value of the function on an entire domain of function.

Relative max of $-x^4-7x^3-12x^2$ is 0 at x=0

and $\frac{3}{512}(133\sqrt57-471)$ at $x=\frac{-21}{8}-\frac{\sqrt57}{8}$

Relative min is

$\frac{-3}{512}(471+133\sqrt57)$ at $x=\frac{-21}{8}+\frac{\sqrt57}{8}$

From the graph we see that

End behaviour is As $\\x->\infty, f(x)->-\infty\\x->-\infty, f(x)->-\infty\\$

Increasing intervals and decreasing intervals are

Increasing: $\frac{1}{8}(\sqrt57-21)$

Decreasing: $\frac{1}{8}(-21-\sqrt57)$

Zeroes are :

$-x^4-7x^3-12x^2=0$

⇒ $(-x^2)(x^2+7x+12)=0$

⇒ $(-x^2)(x+3)(x+4)=0$

Hence, zeroes are 0, 0, -3, -4

IrinaK [193]

He attempted 500 passes since you divide 350 by 7 which, would give you 5 then, you would multiply it by 100 therefore, it gives you 500

Shaun is 4 years older than her sister Charmaine. If the sum of their ages is 16, how old is Charmaine?

skad [1K]

Step-by-step explanation:

$let \: the \: age \: of \: charmaine \: be \: x$

$according \: to \: question$

$4 + x = 16$

$x = 16 - 4$

$12$

$so \: the \: age \: of \: shaun \: is \:$

$x + 4$

$12 + 4$

$16$

Given the expression: 3x10 − 48x2

BartSMP [9]

Factorization involves representing an expression with smaller terms.

When the greatest common factor is factored out, the equivalent expression is: $3x^2(x^8 - 16)$ .
The complete factored expression is: $3x^2(x^4 - 4)(x^4 + 4)$
