Answer:
Step-by-step explanation:
The trick is not to get all caught up in Pythagoras. There is a much simpler way to do it. Find the area of the triangle two different ways. DG and DE are at right angles. That is one way to find area. The other is use the height (DF) and multiply that by the hypotenuse GE.
DG*DE/2 = GE * DF/2 Multiply both sides by 2
DG*DE = GE * DF
DG = 8
DE = 15
GE = 17
8*15 = 17* DF
120 = 17 * DF Divide by 17
120/17 = DF
DF = 7.06

<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.

22.778%
Step-by-step explanation:
0.22778/1*100/100=22.778/100
Answer:7t+5
Step-by-step explanation:
Circle the 2 variables (T)
Next re-write the equation and put the varbiles equation 6t+t.
Then you have 7-2 left, you then put it next to the new equation but make sure when you do that it looks like this 6t+t+7-2.
Last you solve and your answer should be 7t+5.
Note: If a variable is alone like the t then make sure you put a one next to it
