A bag contains 5 red marbles, 4 blue marbles, and 3 yellow marbles. A student removes 1 marble without looking and records the colour. A student removes 1 marble without looking and records the colour. He then places the marble back in the bag before drawing another marble. What is the probability of drawing a colour other than blue, then drawing a yellow marble? Give your answer as a fraction.

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.

step-by-step explanation:

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
