A because there is a difference between a expression and equation. Expressions don’t have a equal sign or an answer. But equations have an equal sign and an answer. So because everything else has an answer or equal sign, the correct answer would be A. Hope this helps!

A bag contains 7 red marbles, 3 blue marbles and 2 green. If two marbles are drawn out of the bag, what is the probability, to t

Setler [38]

Answer:

0.0455

Step-by-step explanation:

The formula for calculator probability is 

# of favorable outcomes / # of possible outcomes

The total number of marbles in the bag: 

7+3+2=12

Probability of the first marble being blue:

3/12

Probability of the second marble being blue:

2/11 -- 2 because only 2 blue marbles left after drawing the first one out, 11 because after taking the first marble out, we have 11 marbles left in the bag

Formula for both events happening:

p(A and B) = p(A) * p(B)

In this problem,

A = first one blue

B = second one blue

Probability that if two marbles are drawn out of the bag, both are blue:

3/12 x 2/11 = 0.045454

Rounded answer:

0.0455 (or 4.55%)

What is the percentage of the change from 6 to3?

luda_lava [24]

Answer:

The percentage of the change from 6 to 3 is a 50% decrease.

Step-by-step explanation:

Given the number '6'.

If the number changes from '6' to '3', means the number reduces to half.

as 6/2 = 3

Thus,

6 → 100%

and when reduces to half

3 → 50%

Thus, the percentage of the change from 6 to 3 is a 50% decrease.

ANOTHER METHOD

% Decrease = (original value - new value) / original value × 100%

= (6 - 3) / 6 × 100%

= 3/6 × 100%

= 0.5 × 100%

= 50%

Thus, the percentage of the change from 6 to 3 is a 50% decrease.
