Answer:
And that represent the probability that they take longer than 7 minutes to solve the puzzles.
Step-by-step explanation:
The complement rule is a theorem that provides a connection between the probability of an event and the probability of the complement of the event. Lat A the event of interest and A' the complement. The rule is defined by:
On this case we have that n= 56 represent the employees selected to solve the puzzles.
We know that 23 out of the 56 selected solved the puzzles in less than 7 minutes.
Let's define the events A and A' like this:
A: Employees solved puzzles in less than 7 minutes
By the complement rule then:
A' : Employees solved puzzles in more than 7 minutes
Based on this we are interested to find the probability for A'
We can begin finding P(A), from the definition of probability we know:
For this case if we replace we got:
And using the complemnt rule we got:
And solving for P(A') we got:
And that represent the probability that they take longer than 7 minutes to solve the puzzles.
Answer:
So then the best option on this case is:
A. 14 and 15
Step-by-step explanation:
When we have a right triangle we can use the Pythegorean identity given by:
(1)
Where Hip represent the hypothenuse. Opp represent the opposite side and Adj the adjacent side.
On this case we have given the hypothenuse assumed because is the only possible reasonable value because
is a too much higher value
We have a ratio provided on this case, let's assume that the ratio is:
If we rpelace this condition into equation (1) we got:
And then we have this:
And then the opposite side is:
The perimeter is defined as the sum of all the sides, we can find the perimeter like this:
And replacing the values that we found we got:
So then the best option on this case is:
A. 14 and 15
Answer:
Step-by-step explanation:
From the question we are told that
5 samples(23 34 37 42 58)
To select 3 random sample
a) Generally to find all 10 possible outcomes and there median we make a table
Therefore
L1
58,42,37 Median=42
L2
58,42,34 Median=42
L3
58,42,23 Median=42
L4
37,34,23 Median=34
L5
58,37,34 Median=37
L6
58,37,23 Median=37
L7
58,34,23 Median=34
L8
42,37,34 Median=37
L9
42,37,23 Median=37
L10
42,34,23 Median=34
