She has 11 friends,
20 of the balls=5 friends and the rest =6 friends. I may be wrong so check this for yourself to be sure. :)
1. 4x + 8y = 12....divide by 4
x + 2y = 3
2y = -x + 3
y = -1/2x + 3/2...slope is -1/2, y int is 3/2
x + 2y = -3
2y = -x - 3
y = -1/2x - 3/2...slope is -1/2 and y int is -3/2
when the slopes are the same, and the y int are different, then the lines are parallel and never intersect...so they have no solution and are inconsistent
=================
2. y = 2x - 1...slope is 2 and y int is -1
y = -2x + 5 ...slope is -2 and y int is 5
when the slopes are different and the y int are different, then there is 1 solution making it independent
=================
3. 4x - 12y = 8...divide by 4
x - 3y = 2
same as other equation meaning the equations are the same line...meaning they have infinite solutions making them dependent
Answer: Mean- 547.3
Median- 575
Mode-no mode
range-550
Step-by-step explanation:
mode is the number that occurs the most
mean- add up all the numbers and divide them by them number of ad ins
range- largest number- smallest number
median- middle number
Annually means per year
One year=12 months
27000/12= 2250$
