Assuming that each marble can be picked with equal probability, we notice that there is a total of

marbles, of which 2 are red.
So, the probability of picking a red marble is

In fact, as in any other case of (finite) equidistribution, we used the formula

Answer: 55 degrees / Acute angle.
Step-by-step explanation:

Answer:
7%
Step-by-step explanation:
Step one:
given data
The original cost of Sam’s investment is $10,000
Sam calculated his real return to be $10,700
Required:
the interest made from the investment is
10700-10000= $700
Step two:
The ROI is a percentage that tells us the interest made
interest/investment*100
=700/10000*100
=0.07*100
= 7%
The ROI is 7%
Answer:
yes
Step-by-step explanation:
Yes, because x=4 so 3x=12 so 12+2=14
Answer: A) 2/3 is shaded. B) 66.67% is shaded.
Step-by-step explanation:
The whole big triangle holds 9 total triangles in it.
Out of the 9 triangles 6 of them are shaded so the fraction will be 6/9 which reduces to 2/3.
Now convert 2/3 to a decimal to find what percentage is shaded.
2/3 = 0.6666...
0.6666 * 100 = 66.666..
66.666 as a percent is 66.67%
