Answer:
Step-by-step explanation:
- √(14 - 2√13) * √(14 + 2√13) =
- √(14 - 2√13)(14 + 2√13) =
- √(14² - (2√13)²) =
- √(196 - 4(13)) =
- √(196 - 52) =
- √144 =
- 12
Answer:
An approximate match
Step-by-step explanation:
The vlookup (vertical lookup) function is a search function in excel used in locating values in an excel table.
The vlookup syntax is written as:
=VLOOKUP(value, table, col_index, [range_lookup])
The range_lookup is an optional parameter which is used to indicate if the search should be for an exact match or approximate match. Since a column, resort fee will be used as a possible additional cost; the search would be required to return an approximate search rather than an exact match in other for the search condition to be adequately implemented.
The true answer is A. all parallelograms are rectangles
Answer:
The chance that the second person has the same birthday is 1/365. To find the probability that both people have this birthday, we have to multiply their separate probabilities. (365/365) * (1/365) = 1/365, or about 0.27%
Answer:
0.1875
Step-by-step explanation:
Let A be the event that class two has been chosen . So the probability of A would be P (A) = 1/2= 0.5
Now class two has 9 girls out of total 24 students . So the probability of chosing the girl would be= P (B=) 9/24= 0.375
So the probability that Classroom #2 was chosen at random, given that a girl was chosen is given by = P(A) . P(B)= 0.5 * 0.375= 0.1875
Another way of finding the probability that Classroom #2 was chosen at random, given that a girl was chosen is by drawing a tree diagram.
P (1/2) Class 1 ------------------------5 boys
-------------------------11 girls (11/16)
P (1/2) Class 2 -------------------------15 boys
-----------------------9 girls P (9/24) Class 2 was chosen (0.5) *9/24
