The teacher of a class needs to select two volunteers from a class of 12 boys and 10 girls. She randomly selects one student and then randomly selects another one . What is the probability she selects one boy and then one girl “think about this one “ can you select both students at the same time or does selecting one affect the other ? Should the denominator change ? is this independent or dependent?

people grow faster than other people.

step-by-step explanation:

should you really be posting this isn't math boi.

c.   x=2.4cm

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.

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
