Segment AB has point A located at (4,2). If the distance from A to B is 3 units, which of the following could be used to calcula

Goshia [24]

The equation to calculate the coordinates of point B is (b) 3 = √(x - 4)²+(y - 2)²

<h3>How to determine the equation?</h3>

The given parameters are:

A = (4,2)
AB = 3

The distance formula is:

AB = √(x - x1)²+(y - y1)²

So, we have:

3 = √(x - 4)²+(y - 2)²

Hence, the equation to calculate the coordinates of point B is (b) 3 = √(x - 4)²+(y - 2)²

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 <u>7/20 or 35%</u>
