Answer:

(6-3w) (-w*w)

Simplifying

(6 + -3w)(-1w * w)

Multiply w * w

(6 + -3w)(-1w2)

Remove parenthesis around (-1w2)

(6 + -3w) * -1w2

Reorder the terms for easier multiplication:

-1w2(6 + -3w)

(6 * -1w2 + -3w * -1w2)

(-6w2 + 3w3)

<u>Excel's Normal Distribution</u>

The normal distribution has two parameters: the mean value $\mu$ and the standard deviation $\sigma$ . Since it's a symmetric function the values at the right side of the center value

The normal distribution is a function which integral cannot be expressed in terms of elemental functions. That is why the cumulative probability is usually found in tables, graphs or any digital media like Excel.

The formula NORM.DIST computes the cumulative values for the left tail or $P( X < X_o)$ for a given mean and standard deviation. The parameters are

$NORM.DIST (X_o,\mu,\sigma,cumulative)$

This last parameter tells the formula we want the cumulative left-tail probability or just the value at Xo. This value must be set to TRUE to compute the probability for a range of values, like in the problem at hand.

Since the formula computes the left-tail of the function, we must take advantage of the symmetry of the distribution if we want to compute right-tail values we just subtract the result from 1.

Thus, the correct formula to calculate the required probability is

D. 1 – NORM.DIST(100, 75, 10, TRUE)

Which exponential function has the greatest average rate of change over the interval [ 0 , 2 ]

PIT_PIT [208]

The exponential function which has the greatest average rate of change over the interval [0, 2] is option B.

<h3>How to calculate the average rate of change?</h3>

Mathematically, the average rate of change between two (2) points can be calculated by using this expression;

$Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}$

For option A, we have:

when x = 0; when x = 2;

y = 3(1.6)^x y = 3(1.6)^x

y = 3(1.6)^0 y = 3(1.6)^2

y = 3. y = 7.68

ΔA = (7.68 - 3)/(2 -0) = 2.34.

For option B, we have:

ΔA = (9 - 4)/(2 -0) = 2.5.

For option C, the exponential function has a common ratio of 2.

ΔA = 2.

For option D, we have:

ΔA = (10 - 8)/(1 -0) = 2.

In conclusion, we can logically deduce that the exponential function which has the greatest average rate of change over the interval [0, 2] is option B i.e 2.5.

What is the meaning of a composite number?

zaharov [31]

Composite number is a positive integer that can be formed by multiplying together two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.[1][2] Every positive integer is composite, prime, or the unit 1, so the composite numbers are exactly the numbers that are not prime and not a unit.

For example, the integer 14 is a composite number because it is the product of the two smaller integers 2 × 7. Likewise, the integers 2 and 3 are not composite numbers because each of them can only be divided by one and itself
