Answer:
take the population mean divided by four
Step-by-step explanation:
3n<50
n<50/3
The variable N represents a whole number.
For what values of n will the sum of n+3 be less than 50?
The median of variable A is the middle value when the all the values for variable A is arranged from smallest to greatest.
The values for variable A are
1, 2, 4, 4, 5, 6, 7, 9
The middle value is between 4 and 5. The median is between 4 and 5.
(4 + 5) /2 = 4.5
The median is 4.5
Answer:
(0,3)
Step-by-step explanation:
Given inequality is
y< x+ 4
to check the solution we plug in each ordered pair and check with our inequality
Lets check (-1,4)
here x=-1 and y =4
We plug in -1 for x and 4 for y in our inequality y<x+4
4 < -1 + 4
4 < 3 that is false, so (-1,4) is not our solution
Now we plug in (0,5), x=0 and y = 5
y < x+4
5 < 0 + 4
5<4 that is false, so (0,5) is not our solution
Now we plug in (0,3), x=0 and y = 3
y < x+4
3 < 0 + 4
3<4 that is true, so (0,3) is our solution
X + 3y = 7
x = -3y + 7
2x + 4y = 8
2(-3y + 7) + 4y = 8
-6y + 14 + 4y = 8
-2y = 8 - 14
-2y = - 6
y = -6/-2
y = 3
x + 3y = 7
x + 3(3) = 7
x + 9 = 7
x = 7 - 9
x = -2
solution is (-2,3)
