Step-by-step explanation:

to "solve" this I need an equation.

this whole expression must be equal to something.

without that I can only try to simplify the expression.

remember that

a/b / c/d = ad / bc

so, here we have

3a/(((a²/x) - 1)(a/x - 1)) = 3a/(a³/x² - a²/x - a/x + 1) =

= 3a/(a³/x² - a²/x - a/x - a/a) =

= 3a/((a²/x² - a/x - 1/x - 1/a)×a) = 3/(a²/x² - a/x - 1/x - 1/a)

Draw a picture to show the product of 4:7 x 3. Then write the product

Hoochie [10]

Answer:

¹²/₇

Step-by-step explanation:

Model ⁴/₇ × 3

Assume that you have three pies, each dived into seven slices.

There are only four slices remaining in each pie, that is, there is ⁴/₇ pie in each pie plate

The picture represents ⁴/₇ × 3.

Model the product

Now, transfer slices to get as many filled pie plates as possible.

Count the total slices.

You have 12 slices, and each slice represents ⅐ of a pie.

You have ¹²/₇ pie.

∴ ⁴/₇ × 3 = ¹²/₇

In a study investigating the effect of car speed on accident severity, the vehicle speed at impact was recorded for 5,000 fatal

sleet_krkn [62]

Answer:

68%

Step-by-step explanation:

Given that:

Mean speed (m) = 46

Standard deviation (s) = 13

Approximately what percentage of vehicle speeds were between 33 and 59 mph

Obtain the Zscore for P(Z < x) for both values and subtract :

For x = 33

Zscore :

Z = (x - m) / s

Z = (33 - 46) / 13 = - 1

p(Z < - 1) = 0.15866 ( Z probability calculator)

For x = 59

Zscore :

Z = (x - m) / s

Z = (59 - 46) / 13 = 1

p(Z < 1) = 0.84134 ( Z probability calculator)

Hence, 0.84134 - 0.15866 = 0.68268 = 0.68

0.68 * 100% = 68%

-6, -6) and (-2, -2) Find the rate of change of the line that passes through the points.

Kamila [148]

Rate of change of line that passes through the given points is 1

Step-by-step explanation:

The ratio of vertical and horiontal changes is called the rate of change of a line. It is called slope which is denoted by m.

The formula for slope when (x1,y1) and (x2,y2) are the points on line is given by:

$m = \frac{y_2-y_1}{x_2-x_1}\\$

Given

(x1,y1) = (-6,-6)

(x2,y2) = (-2,-2)

Putting the values in the formula

$m = \frac{-2-(-6)}{-2-(-6)}\\=\frac{-2+6}{-2+6}\\=\frac{4}{4}\\= 1$

Rate of change of line that passes through the given points is 1
