The appropriate measure of variation (spread) for these data points is "Standard deviation."

<h3>What is Standard deviation?</h3>

The standard deviation would be a statistic that calculates as the square root of the variance and measures the distribution of a set of data relative to its mean.

Some key features regarding the Standard deviation are-

  • The standard deviation is determined as the square root of the variance by determining the deviation of each data point from the mean.
  • In finance, standard deviation is frequently employed as an assessment of an asset's relative riskiness.
  • A volatile stock does have a high standard deviation, whereas a stable blue-chip stock has a low deviation.
  • The standard deviation, on the other hand, calculates those ambiguity as risk, even when it is in the investor's favor, like above-average returns.

Explain how to find the x-intercept of the graph of y = 4x - 2.
Vlad1618 [11]

There are two ways to do this. The first of which is the algebraic method. Plug in y = 0 and solve for x.

y = 4x - 2

0 = 4x - 2 ... y is replaced with 0

4x-2 = 0

4x-2+2 = 0+2 ... we add 2 to both sides

4x = 2

4x/4 = 2/4 .... divide both sides by 4

x = 1/2

x = 0.5

The x intercept is x = 1/2 or x = 0.5

--------------------------

The other approach is to graph the equation y = 4x-2, and mark where the line crosses through the x axis. You should find it crosses through x = 1/2 or x = 0.5; the x intercept as an ordered pair would be (1/2, 0) or (0.5, 0)

side note: the equation y = 4x-2 goes through the points (0,-2) and (1,2). You find this by plugging in x = 0 and x = 1 respectively to find the corresponding y values.

If (ax + 2)(bx + 7) = 15(x*2) + cx + 14 for all values of
Juli2301 [7.4K]

If (ax + 2)(bx + 7) = 15(x * 2) + cx + 14 for all values of x, and a + b = 8 then the two possible values for c is 31 and 41.

<h3>What is meant by linear equation?</h3>

A linear equation is an algebraic equation with only a constant and a first-order (linear) term of the form y = mx + b, where m is the slope and b is the y-intercept. The above is sometimes referred to as a "linear equation of two variables," where y and x are the variables.

Let the equation be

(ax + 2)(bx + 7) = 15$$x^2 + cx + 14

(ax + 2)(bx + 7) = ab$$x^2 + 7ax + 2bx + 14 = ab$$x^2 + (7a + 2b) + 14

On comparing both equations

ab = 15     ------ (1)

7a + 2b = c   -------(2)

Also, it is given that a + b = 8  --------(3)

From equations (1) and (3) it can be observe that either a or b equal to 3 or 5

From equation (2),

When a = 3 and b = 5, then c = 7(3) + 2(5) = 21 + 10 = 31

When a = 5 and b = 3, then c = 7(5) + 2(3) = 35 + 6 = 41

Therefore, the correct answer is option D) 31 and 41
