Brooke is 8 years old! This is what I did⬇️
5x2=10. (In 5 yrs 10 will add to the sum of their age.
29-10=19. (The sum of their ages right now is 19)
11 + 8 = 19 ( 11 is 3 more than 8 and it equals their ages together)
Brooke:8
Samantha:11
Answer:
[7-2x+5y-(x-y) -[5x+3y-7]
= 7-2x+5y-x+y-5x-3y+7
=7+7-2x-x-5x+5y+y-3y
=14-8x+3y
=-8x+3y+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.
