5) You randomly choose a marble from a jar. The jar contains 4 red
marbles, 10 blue marbles, 7 green marbles, and 6 yellow marbles. Find the
probability of the event choosing a yellow marble *
.2/9
.4/27
.5/27
.5/9

the  probability of the event choosing a yellow marble is 2/9 .

Step-by-step explanation:

Here we have , to choose a marble from a jar. The jar contains 4 red

marbles, 10 blue marbles, 7 green marbles, and 6 yellow marbles. We need to Find the  probability of the event choosing a yellow marble . Let's find out:

According to question question we have following parameters as :

Red marbles = 4

Blue marbles  =10

Green marbles = 7

Yellow marbles = 6

Now , Probability to chose a yellow marble is :

Favorable outcomes = 6(Number of yellow marbles )

Total outcomes = 4+10+7+6 = 27( Total marbles )

Hence ,

⇒

⇒

Therefore ,  the  probability of the event choosing a yellow marble is 2/9 .

2/9

Step-by-step explanation:

To find the probability first you must get the amount of yellow marbles

In this case, it is 6 yellow marbles

Then you must find the total amount of marbles in the jar so,

4 + 10 + 7 + 6 = 27

Next you must use the numbers we have and put them in this fraction where the number of yellow marbles is over the total amount of marbles in the jar.

So, 6/27, then you must simplify this fraction

6/27 simplified is 2/9

Answer = 2/9

My explaining isn't that great but hope it helps!!

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
