Answer:
The correct answer is there are 15 samples each of size 4 to choose from the population and the population mean is 27.
Step-by-step explanation:
Total number of lottery tickets = 6
Number of samples of size 4 that can be drawn from this population of 6 lottery numbers are =
= 15.
Now the population mean is given by
× ∑ x , where n is the number of lottery tickets and ∑ x is the sum of the lottery numbers.
Summation of the lottery ticket numbers is 162
Thus the population mean is given by
= 27.
Y=2x+5
4x-2y=-10
4x-2(2x+5)=-10
4x-4x-10=-10
-10=-10
Louis = x
Jane = 2x (Twice as many as Louis)
Together they have 360
x + 2x = 360
3x= 360
x=120
2(120)= 240
Jane addresses 240 envelopes
Answer:
34,5 ?? I am not good at this but I did 92-23 that's 69 ÷ 2 = 34.5 ?
If two points intersect,then their intersection is a line.A line contains at least twon points. if two lines intersect then exactly one plain contains both lines.
