The answer would be D. Because there was 19 in total and you took a marble out so that makes it 18 then you want the probability of the blue so 4/18 which equals 2/9
Hope this helps
Have a great day/night
Answer:
The correct answer is 6.
Step-by-step explanation:
2x2 – 2x + 10 <------ This is the original expression.
2x2 – 2(4) + 10 <----- Change the variable.
4 - 2(4) + 10 <------- Do the multiplication to the left.
4 - 8 + 10 = <------ Do the multiplication in the middle.
-4 + 10 = <----- Do the subtraction to the left.
6 <----- Simplify
Hope this helps! :D
Answer:
Jogging = 10 hours
Swimming = 7 hours
Cycling = 3 hours
Step-by-step explanation:
J = Hours jogging
S = Hours swimming
C = Hours cycling
Since jogging is the activity that burns the most calories, we should maximize the number of hours jogging:
![C+S+J = 20\\C+S=20-J\\J\leq C+S\\J\leq 20-J\\J\leq 10](https://tex.z-dn.net/?f=C%2BS%2BJ%20%3D%2020%5C%5CC%2BS%3D20-J%5C%5CJ%5Cleq%20C%2BS%5C%5CJ%5Cleq%2020-J%5C%5CJ%5Cleq%2010)
Therefore, the man should jog for 10 hours.
Since swimming is the activity that burns the second most calories, we should maximize swimming hours:
![C+S=10\\S\leq 7\\S=7\\C=3](https://tex.z-dn.net/?f=C%2BS%3D10%5C%5CS%5Cleq%207%5C%5CS%3D7%5C%5CC%3D3)
In order to maximize the number of calories burn, the man should go jogging for 10 hours, swimming for 7 hours and cycling for 3 hours.
I believe the correct answer is 6,240 so you had subtract 260 from 6500
