4 0

${7}^{ - \frac{5}{6} } \times {7}^{ - \frac{7}{6} } \\ = {7}^{ - \frac{5}{6} - \frac{7}{6} } \\ = {7}^{ - \frac{12}{6} } \\ = {7}^{ - 2} \\ = \frac{1}{ {7}^{2} } \\ = \frac{1}{49}$
The answer is 1/49

A pencil holder contains only six blue pencils and three red pencils. If two pencils are drawn at random, what is the probabilit

erastova [34]

6 blue pencils and 3 red pencils means 9 total pencils. So the probability of pulling out ONE blue pencil would be 6/9 or about 67 percent. TWO blue pencils would be HALF of that. So 6/9 * 1/2 which is 6/18 or 1/3 or about 33 percent.

Is the answer 4/5 ? Can someone help please ?

Zina [86]

Answer:

$m=-\frac{4}{5}$

Step-by-step explanation:

We can take 2 arbitrary points in the graph and solve for slope using the formula shown below.

<u>Note:</u> we will use the 2 points (2,-3) & (-3,1)

Where x_1 = 2, y _1 = -3 and x _ 2 = -3 and y _ 2 = 1

The formula:

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

Let's plug the numbers and find the slope:

$m=\frac{1-(-3)}{-3-2}\\m=\frac{4}{-5}\\m=-\frac{4}{5}$

Hence, thsi is the slope.

Mario has LaTeX: 2\frac{1}{4}2 1 4 pounds of trail mix. He puts equal amounts of the trail mix into 6 bags for a hike with his f

ioda

Answer:

<h2><em>0.375 pounds </em></h2>

Step-by-step explanation:

Let the amount of trail mix in each bag be x pounds. If Mario has $2\frac{1}{4}$ pounds of trail mix and puts equal amounts of the trail mix into 6 bags for a hike with his friends, the amount of trail mix in each bag can be derives using the expression;

$2\frac{1}{4} = 6 * x$

solving for x

$\dfrac{9}{4} = 6x\\\\2.25 = 6x\\\\divide\ both \ sides \ by \ 6\\\\\dfrac{2.25}{6} = \dfrac{6x}{6} \\\\x = 0.375\\$

<em>Hence 0.375 pounds of trail mix will be in each bag</em>
