Same I’m stuck on this one too
Answer:
15.15% probability that both months (different) have less than 31 days.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Also, the order of the months is not important. For example, picking July and August is the same as picking August and July. So the combinations formula is used to solve this problem
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
There are 12 months, of which February, April, June, September and November, that is, 5 of them, have less than 31 months.
Desired outcomes:
Picking 2 months from a set of 5(those with less than 31 days). So
Total outcomes:
Picking 2 months from a set of 12(all the months). So
Probability:
15.15% probability that both months (different) have less than 31 days.
Answer:
3 + 5 = 8 which is a monomial
Step-by-step explanation:
a binomial has 2 terms; example, 3y + 5
Answer:
Multiply (400 + 20 + 3) x 10000
Add 4 zeros to the end of 423
Step-by-step explanation:
423 x 10,000 = Adding the amount of zero’s in 10000 to 423
Answer:
Not proportional.
Step-by-step explanation:
Given ratios:
To tell whether the ratios are proportional or not.
Solution:
In order to tell whether the given ratios are proportional or not, we will reduce the fractions to the simplest numbers by dividing the numerator and denominator by their greatest common factor and then comparing them. If they are equal then the ratios are proportional else not proportional.
So, the simplest form of 4/2 can be calculated by dividing both by 2 as it is the G.C.F.
the simplest form of 8/6 can be calculated by dividing both by 2 as it is the G.C.F.
Now, since 2/1 does not equal 4/3, hence the ratios are not proportional.
