Answer:

3x² – 5x + 2 is a polynomial because:

Exponents are whole numbers, and the expression has at least 1 term.

Exponents other than whole numbers can take the form of variables in denominators, and roots which we don't want.

Suppose that a normal distribution has a mean of 20 and a standard deviation of 4. What is the z-score of 13?

Papessa [141]

Answer:

-1.75.

Step-by-step explanation:

The z-score = (n - m) / d where n is the value (13) m = mean and d = standard deviation.

= (13 - 20) / 4

And it's elimination using addition and subtraction <br> x-y=1<br> x+y=3

MatroZZZ [7]

Get one x+y=3 to y=x+3 and plug it into x-y=1 and you get x-(x+3)=1. Destitute the x and solve. Once you get what x equals plug it to to either equation for the value of x and solve for y

A marketing company is designing a new package for a box of cereal. They have determined that the function C(x) = 4.5 x2 models

Vlad1618 [11]

So the function is

$\\ \rm\rightarrowtail y=4.5x^2$

As we know

x²≥0
x≥0

hence domain is

$\\ \rm\rightarrowtail D_f\in R$

Least value of function is at x²=0 i.e 0

Hence range:-

$\\ \rm\rightarrowtail R_f\in [0,\infty)$

One third of a number reduced by 11 is equal to 4 more than the number

Alecsey [184]

1/3x -11 = 4+x is what we start with, then add 11 to both sides, then subtract x from both sides. Then when we divide both sides by -2/3, x will equal -22.5.
