Answer:
D. 550 years
Step-by-step explanation:
Firstly, you need to understand the meaning of B.C.E. and C.E. B.C.E. means "Before common era", where "common era" is the year where Jesus Christ was born (I will just call it "The Year" since the name is so long). The date has been used as a dating system for many years.
In this case, 300 B.C.E. means 300 years before "The Year" whereas 250 C.E. means 250 years after "The Year". Thus, the total would be:
300 + 250 = 550 years
Answer:
Step-by-step explanation:
The sample space for the experiment is:
- Number of elements in S, n(S)=12
Given an event E such that:
- Number of elements in E, n(E)=8
The outcomes in the complement of E are the outcomes in S that are not in E.
- Number of elements in the complement of E,
Therefore:
THE ANSWER IS C because the 6 is in the thousandths place
Answer:
IV: colour of the room
DV: The number of minutes each group spends studying
Step-by-step explanation:
IV(Independent Variable) : is what is changed in the experiment and the colour of the room is being changed.
DV(Dependent Variable) : is what is measured in the experiment and the number of minutes in spent on studying is measured.
There are only 23=823=8 possible ways to arrange the genders boy/girl, with repetition. Since the probability of boy and girl are equal, the probability of each of these arrangements are also equal. We can therefore count the number of possible "good" answers, and divide by 8.
There are 3 possible ways to have 1 boy, that being "first/second/third child is boy", so the probability of exactly 1 boy is indeed 3838.
Having at most 2 girls is the opposite of having three girls, so since there are only one way of having three girls, there must be 8−1=78−1=7 ways of having at most two girls, so the probability of at most two girls is indeed 78
