Not sure I think maybe its the second choice. Sorry cant be certain.
Using addition
x-y+1/2x+y=1+5
x+1/2x+0y=6
3/2x=6
3x=12
x=4
Using the value of x
x-y=1
4-y=1
y=3
With x as 4 and y as 3, their product is 12
And can be written as (4,3)
Answer:
Clare's score was 70.
Step-by-step explanation:
N = 20
M = 30
C = ?
Mean = (Sum of all values)/3
40 = (20 + 30 + c)/3
40 = (50 + c)/3
50 + c = 120
c = 70
Answer:
Discrete variable
Step-by-step explanation:
We are given the following in the question:
Variable:
Total number of points scored in a football game
Discrete and continuous data:
- Discrete data is the data that can be expressed in whole numbers. They cannot take all the values within an interval.
- Discrete variables are usually counted and not measured.
- Continuous variable can be expressed in fractions and can take any value within an interval.
- Continuous variable are usually measured and not counted.
Since, total number of points score in a foot game are expressed in whole numbers and cannot be expressed in decimals, they are discrete variable. They cannot take all the values within an interval and they are usually counted.
Thus,
Total number of points scored in a football game is a discrete variable.
