There are 20 blue dye 6 red dye and 14 green dye what is the probability of me selecting the green dye

Vesnalui [34]

Answer:

$\boxed {\boxed {\sf \frac{7}{20} \ or \ 35 \% }}$

Step-by-step explanation:

Probability tells us how likely something is to occur. It is found by dividing the favorable outcomes by the total outcomes.

$P=\frac{favorable \ outcomes}{total \ outcomes}$

In this question, a favorable outcome is selecting a green dye. The total outcomes are all the dyes.

Favorable outcomes (green dye): 14
Total outcomes (all dyes): 20 blue+ 6 red+14 green=40

$P(green \ dye)=\frac{14}{40}$

Reduce the fraction. Both the numerator and denominator can be divided by 2.

$P(green \ dye) =\frac{14/2}{40/2}$

$P (green \ dye)=\frac {7}{20}$

This is the probabilty as a fraction. It can also be written as a percent. Divide the fraction, then multiply by 100.

$P(green \ dye)=\frac{7}{20}*100$

$P(green \ dye)=0.35 *100$

$P(green \ dye)=35 =35 \%$

The probablity of selecting a green dye is 7/20 or 35%

Write an equation in slope-intercept form of the line that contains the point (-2, 2) and has the slope = -5.

vichka [17]

Answer:

$y=-5x-8$

Step-by-step explanation:

Given the following question:

To calculate the slope intercept of a line/point we need to use the formula for slope intercept, substitute, and solve for b.

Formula for slope intercept:
$y=mx+b$
$m=-5$
$y=2$
$x=-2$
$2=-5(-2)+b$

Solve for b:
$2=-5(-2)+b$
$-5(-2)=10$
$2=10+b$
$10-10=0$
$2-10=-8$
$-8=b$
$b=-8$

Substitute for the following:
$y=mx+b$
$b=-8$
$m=-5$
$y=-5x-8$

Your answer is "y = -5x - 8."

Hope this helps.
