Answer: 35/132
Step-by-step explanation:
probability of drawing green marble: 7/12
since the green marble drawn won't be returned to the box, the new total amount of marbles in the box is 11.
probability of red marble: 5/11
then multiply the 7/12 and 5/11 together:
35/132 which is abut 26.5%
Answer:
ok
Step-by-step explanation:
ok
Answer:
we have:
∆BDE is similar to ∆BAC
so their side are proportional :
BD/BD=BE/BC
2/BD=4/(6+4)
BD=2×10/4
BD=5
again
BE/BC=DE/AC
4/10=5/AC
AC=5×10/4
AC=25/2
Now,
<u>AC</u><u>=</u><u>2</u><u>5</u><u>/</u><u>2</u><u> </u><u>or</u><u> </u><u>1</u><u>2</u><u>.</u><u>5</u><u>.</u>
<u>AD</u><u>=</u><u>BA-BD</u><u>=</u><u>5</u><u>-</u><u>2</u><u>=</u><u>3</u><u>.</u>
<u>is</u><u> </u><u>your</u><u> </u><u>answer</u><u>.</u>
Answer:
<u>The true statements are: 3, 4 and 5</u>
Step-by-step explanation:
See the attached figure
According to the figure, we will check the options:
- There are exactly two planes that contain points A, B, and F. ⇒ (<u>Wrong</u>)
- There is exactly one plane that contains points E, F, and B. ⇒ (<u>Wrong</u>)
- The line that can be drawn through points C and G would lie in plane X. ⇒(<u>True</u>)
- The line that can be drawn through points E and F would lie in plane Y. ⇒(<u>True</u>)
- The only points that can lie on plane Y are points E and F.⇒(<u>True</u>)
In a graph this means from the point that your'e at, move down 3 lines.
