Answer:
same slope, different intercepts (parallel lines essentially)
Step-by-step explanation:
Estimation is 1,200 cause 400 x 3 = 1200 so that’s what I would estimate
Answer:
>
Step-by-step explanation:
Absolute value means whatever is inside of it is always positive so 15 is greater than -12.
Answer:
Variance = 24900
Standard Deviation = 157.7973
Step-by-step explanation:
We are given the following in the question:
Number of admissions: 1000 1200 1500
Admissions Probability: 0.6 0.3 0.1
Formula:
Variance =
Thus, the variance is 24900.
Standard Deviation =
Thus, the standard deviation is 157.7973
Answer:
14 and 6
Step-by-step explanation:
Let's start by naming the first number x.
We can name the second number y.
We can set up equations to model our situation.
x+y=2x-8
x-y=2y-4
Let's simplify the equations.
x+y=2x-8
Subtract 2x from both sides
-x+y=-8
__________
x-y=2y-4
Subtract 2y from both sides.
x-3y=-4
Add the two equations together to eliminate x.
x-3y=-4
-x+y=-8
________
0x-2y=-12
-2y=-12
Divide both sides by -2.
y=6
The second number is 6.
Plug that back in.
x+6=2x-8
Subtract x from both sides
6=x-8
Add 8 to both sides
x=14
The first number is 14
