Answer:
Mean: $217,822
Median: $244,614
Step-by-step explanation:
The mean and median sales prices of new homes sold in the United States in February 2016 were $ 217822 and $ 244614 , respectively.
Mean and median, then the term respectively.
This means that first comes the mean, and then the median.
So
Mean: $217,822
Median: $244,614
Answer: 6
Explanation:
3(4-2) = 3(2) = 6
-1400 + 800 - 350 = - 950 meters
Answer:
Dilation of 3
Step-by-step explanation:
Answer:
x = 50*e∧ -t/100
Step-by-step explanation:
We assume:
1.-That the volume of mixing is always constant 300 gallons
2.-The mixing is instantaneous
Δ(x)t = Amount in - Amount out
Amount = rate * concentration*Δt
Amount in = 3 gallons/ min * 0 = 0
Amount out = 3 gallons/min * x/ 300*Δt
Then
Δ(x)t/Δt = - 3*x/300 Δt⇒0 lim Δ(x)t/Δt = dx/dt
dx/dt = - x/100
dx/ x = - dt/100
A linear first degree differential equation
∫ dx/x = ∫ - dt/100
Ln x = - t/100 + C
initial conditions to determine C
t= 0 x = 50 pounds
Ln (50) = 0/100 * C
C = ln (50)
Then final solution is:
Ln x = - t/100 + Ln(50) or
e∧ Lnx = e ∧ ( -t/100 + Ln(50))
x = e∧ ( -t/100) * e∧Ln(50)
x = e∧ ( -t/100) * 50
x = 50*e∧ -t/100
