In total there are 12 marbles because 6+4+2=12 and it says you pick 2 marbles from the hat so you subtract 12-2 and that gives you 10 and it says the marbles aren't returned so therefore you are left with 10 marbles. Hope this helps .
Step-by-step explanation:
You are given the equation 36 = 9x² + 4y². You are asked to find the slopes of the asymptotes of the hyperbola. A hyperbola has the following general equation x²/a² + y²/b² = 1. the goal here is to find the slopes of the hyperbolic equation. So divide both sides by 36
36 = 9x² + 4y²
(1/36)[36 = 9x² + 4y²]
1 = x²/4 + y²/9
a² = 4
a = 2
and
b² = 9
b = 3
To find the slope, divide a/b and you will get 2/3.
Answer:
Her average per day was 750 meters.
Step-by-step explanation:
To find the average, add all the numbers up in the set and divide by how many numbers there are.
650 + 675 + 725 + 800 + 900 = 3750. Divide it by 5 and you get 750
