Answer:
Cross probability
Step-by-step explanation:
The type of probabilities remains to be determined. That is the question itself. The same problem is found in the book "Understanding basic statistics 7th edition of Brase".
I will assume that the three probabilities to find are:
a) p (woman asked for a raise)
b) p (received raise | asked for one)
c) p (received raise and asked for one)
So,
a) p(woman asked for a raise)
It is given in the statement, so it is simple statistics:
b) p(received raise | asked for one)
It is also found in the statement, however, now the formula would be given by:
<em>p(received raise | asked for one) = p(received raise and asked for one) / p(asked for one)</em>
c) p(received raise and asked for one)
For this case the formula is given differently and it is necessary to re-adjust formula B, as follows:
<em>p(received raise and asked for one) = p(received raise | asked for one) * p(asked for one)</em>
So,
p(received raise and asked for one) = 11.5%
Answer:
A) 20°
Step-by-step explanation:
Sine and cosine are co-function complements which means that value of sine of an angle is equal to the value of cosine of the complementary angles.
This can be represented by:
Given statement:
Applying co-function complements
Since, we can represent 70° = 90°-20°
So
Thus, makes the statement true.
