Answer:

should be 66.4

Step-by-step explanation:

triangular prism:

Using the formulas

AB=s(s﹣a)(s﹣b)(s﹣c)

V=ABh

s=a+b+c

Solving forV

V=1

4h﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=1

4·3·﹣24+2·(2·2)2+2·(2·2)2﹣24+2·(2·2)2﹣24≈5.19615

5.2 · 2 = 10.4

Rectangular prism:

V=whl=2·2·14=56

10.4+56=66.4

A jar contains 4 red and 8 blue marbles a marble is drawn from the jar what is the probability that a red marble is drawn ?

frosja888 [35]

There is a 1/3 chance that a red marble would be chosen.

To find out you put add up the marbles, so they will make 12 marbles.

Since there are 4 red you put 4/12.

4/12 simplified is 1/3.

So the chance of a red marble being picked is 1/3.
