Answer:
The mean is: 85
Step-by-step explanation:
First you need to add everything up :
1 * 2 = 2
2 * 1 = 2
3 * 3 = 9
4 * 5 = 20
5 * 4 = 20
6 * 3 = 18
7 * 2 = 14
(I multiplyed them all first because i was fast than doing 4+4+4+4+4 because its the same as 4 * 5)
then add them all up 2+2+9+20+20+18+14=85
Answer:
The median is: 4
Step-by-step explanation:
Get the data in NUMERICAL ORDER (smallest to largest), then eliminate the extremes until we're at the middle. (basically chopping off the end till you get to the middle) Therfore The answer would be 4.
Answer:
The mode would be: 4
Step-by-step explanation:
The mode is Get the data in NUMERICAL ORDER, and see which value is the most frequent (we can have more than one mode).
Answer:
25%
Step-by-step explanation:
firs you do 5 divided by 20 because there are 20 x's. this will = 0.25
0.25 = 25%
I hope I get brainiest. Sorry for taking forever. Have a nice day!
Answer:
the slope of this line is 3/4
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
The addition method is a good choice in this case since you have x in one equation and -x in the other equation, and x and -x add to zero, eliminating x.
x - 5.5y = -14
-x + 2.6y = 8.2
Add the equations. x and -x ad to zero, eliminating x. Then solve for y.
-2.9y = -5.8
Divide both sides by -2.9
y = 2
Substitute 2 for y in the first original equation, and solve for x.
x - 5.5y = -14
x - 5.5(2) = -14
x - 11 = -14
x = -3
Solution: x = -3; y = 2
Since the coefficients of y in the two original equations are not opposites, the addition method would not be the best method to use to solve for y first.
