Answer:

x = -2

Step-by-step explanation:

Equation is given as;

4 x - 5 = 2 + 3 ( x - 3 )

Step 1: Expand the brackets

4x - 5 = 2 + 3x - 9

Step 2: Collect like terms

4x - 3x = 2 - 9 - (-5)

Step 3: Simplify

x = 2 - 9 + 5

x = -2

Write the equation of the line given the slope and point that it passes through
Harman [31]

Answer:

Assuming you want the answer in slope-intercept form, it’s <u>y = -5x + 11</u>

Step-by-step explanation:

So we have to first use point-slope form, y - y1 = m (x - x1)

If we plug the numbers in we get...

y + 4 = -5 (x - 3) (take out parenthesis)

y + 4 = -5x + 15 (now subtract 4 from 15)

<u>y = -5x + 11</u>

I think this is right

Which one of the following is always true?a. The coefficient of variation measures variability in a positively skewed data set r
Tom [10]

Answer:

C. The coefficient of variation is a measure of relative dispersion that expresses the standard deviation as a percentage of the mean, for any data on a ratio scale and an interval scale

Step-by-step explanation:

Th Coefficient of Variance is a measure of dispersion that can be calculated using the formula:

CV = \frac{\sigma_{x} }{\mu_{x} } * 100%

Where \sigma{x} is the Standard Deviation

and \mu_{x} is the sample mean

From the formula written above, it is shown that the Coefficient of Variation expresses the Standard Deviation as a percentage of the mean.

Coefficient of variation can be used to compare positive as well as negative data on the ratio and interval scale, it is not only used for positive data.

The Interquartile Range is not a measure of central tendency, it is a measure of dispersion.

Fernando has two equally-sized containers of clay which he is using to build a pyramid-like structure. The finished structure wi
evablogger [386]

Answer:

Fernando does not have enough clay to finish the structure since, the expressions for the volume left are not the same.

Step-by-step explanation:

Let w be the length of the longest slab. Since each slab is 2 inches less than the one beneath it, we have the width of the other 3 slabs as w - 2, w - 2 - 2 = w - 4 and w - 4 - 2 = w - 6 respectively.

Since the base of each slab is a square and has thickness 2 inches, the volume of each slab from largest to smallest is thus 2w², 2(w - 2)², 2(w - 4)² and 2(w - 6)² respectively.

We have that we have half of the container of clay left after forming the first two slabs(which are the bottom-most slabs). Let V be the volume of each clay container. Since we have half left, that is V/2, we have used 2V - V/2 = 3V/2 to make the two bottom-most slabs.

So, 3V/2 = 2w² + 2(w - 2)²

= 2w² + 2(w² - 4w + 4)

= 2w² + 2w² - 8w + 8

= 4w² - 8w + 8

= 4(w² - 2w + 2)   (1)

Also we want to know if V/2 is equal to the volume of the two top-most slabs.

So, V/2 = 2(w - 4)² + 2(w - 6)²

= 2(w² - 8w + 16) + 2(w² - 12w + 36)

= 2w² - 16w + 32 + 2w² - 24w + 72

= 4w² - 40w + 104

= 4(w² - 10w + 26)

From (1) V/2 = 4(w² - 2w + 2)/3 ≠ 4(w² - 10w + 26)

<u>Since the expressions for the remaining volume are not the same, Fernando does not have enough clay to finish the structure.</u>
