45/75 = 30/x
30*75 = 2250/45 = 50
EF = 50 in.
F(x) = 3x^2 + 1
g(x) = 1 - x
(f - g)(x) = 3x^2 + 1 - (1 - x) = 3x^2 + 1 - 1 + x = 3x^2 + x
(f - g)(2) = 3(2)^2 + 2 = 3(4) + 2 = 12 + 2 = 14.
Answer:
<h2>Conditional frequencies offer more specific information to analyse certain data set.</h2>
Step-by-step explanation:
A conditional frequency is a type of relative frequency which involves a condition to be defined.
For example, the conditional frequency of having a house given that the person is female. Notice that this example shows the condition "being female", so the conditional frequency would be all females who own a house.
On the other hand, the relative frequency is just a ratio between the frequency of the data and the total number of data. It's doesn't includes a condition to be defined, that's the difference.
Therefore, conditional frequencies offer more specific information to analyse certain data set.
