Probability =
(number of ways it can come out the way you want)
divided by
(total number of ways it can come out).
Total number of ways to draw a marble = 30 (marbles in the bag).
Number of ways it can succeed = 15 (number of red or green ones)
Probability = 15/30 = 1/2 = 50% .

Answer:
8
Step-by-step explanation:
Compatible numbers are defined as the numbers which are very close to the numbers that they are replacing that divides evenly into each other.
In the context, we have to estimate the quotient using the compatible numbers in order to estimate 245 divided by 3.
So, estimating 245 as 240 and 3 as 30.
Here, 240 is very close to 245 and 30 is close to 3. So the quotient is the result when we divide 240 by 30 and it divides evenly into 240.
We first divide the non zero parts of each number i.e. 24 by 3 to get the first part of the estimate.
Then we add on the zero if there were left in the problem to get your estimate.
Therefore,
240 / 30 = 8
So here, the quotient is estimated as 8.
Answer:
7 - x meters
Step-by-step explanation:
This is a difference of squares. The formula for difference of squares is
a^2-b^2 = (a-b)(a+b)
So plug the numbers we know into this formula.
Area = lw
49 - x^2 = (a-b)(7+x)
49 - x^2 = (7-x)(7+x)
<u>The length is 7 - x meters.</u>
