3 0

Answer: 9

Step-by-step explanation:

Since the percent is decaying, you subtract 3.4 from 100, which gets you 96.6

200(0.966)^9 gets you 146.5 which is less than 150

A bag contains 3 red marbles 4 blue marbles and 7 Green marbles if two marbles are drawn out of the bag what is the probability
mr_godi [17]

Answer:

0.368

Step-by-step explanation:

Number of red marbles= 3

Number of blue marbles= 4

Number of green marbles= 7

Total number of marbles= 3+4+7= 14

Let the first ball is taken out to be red

P(R)=\frac{3}{14}

than again a second ball is drawn, number of balls left= 14-1=13

Number of red= 2

P(R)=\frac{2}{13}

Total probability=\frac{3}{14}+\frac{2}{13}

Total probability= 0.368

Hence, the correct answer is 0.368

Which of the following is the symbol for parallel lines AB and XY?
igor_vitrenko [27]

Answer

A is the symbol for parallel lines AB and XY.

Explanation

B shows that line segment AB and XY are parallel, because there are no arrows, and line segments do not extend forever.

C shows that ray AB and XY are parallel, because there is one arrow, and rays only extend on one point.

Only A shows that line AB and XY are parallel. Lines extend forever, the A shows that AB and XY are parallel, since there are arrows in both directions above AB and XY.
