A good way of doing this problem would be to use cross multiplication of ratios
<u />
Then cross multiply
(10 girls)(270 students)=(X girls)(18 students)
2700=18x
150=x
Answer:
C
Step-by-step explanation:
sorry if I'm wrong-
2. Look at which density value has the most samples, or which value has the most x's.
3. Look at the greatest density recorded and the lowest density recorded. What is the difference between these two densities? For example, if 1 and 3 were the lowest and greatest densities the answer would be 2.
Answer:
Step-by-step explanation:
Firstly you must understand you want to get the value of y.
So put in values into equation which make x.
To understand here lets look at y = 0
if y is to be 0 then x is 3.
If we substitute this value into equation (B) we get the result.
Now we have identified our answer, all is left is to substitute all other values of x and see if y are true.
So , we can see B is the answer
Answer:
5
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 8, - 3) and (x₂, y₂ ) = (- 1, - 4)
d = 
= 
= 
= 
= 
= 5
