Natasha2012 [34]

Answer:

$X=\$1.64*10^9$

Step-by-step explanation:

From the question we are told that:

Population size $P=918000$

Rate of Population increase $\frac{dP}{dt}=9700$

Average annual income $I= \$34,549$

Rate of annual income increase $\frac{dI}{dt}=\$1300$

Generally the equation for Total Income is mathematically given by

$X=P \frac{dI}{dt}+I \frac{dP}{dt}$

$X=918000*1400+(9200*30593)$

$X=\$1.64*10^9$

The time to fly between New York City and Chicago is uniformly distributed with a minimum of 120 minutes and a maximum of 150 mi

rewona [7]

Answer:

a. 8.66 minutes

Step-by-step explanation:

Since the flight times are uniformly distributed, the standard deviation can be calculated as follows:

$\sigma = \frac{b-a}{\sqrt{12}}$

Where '<em>b' </em>is the maximum flight time (150 minutes) and '<em>a' </em>is the minimum flight time (120 minutes):

$\sigma = \frac{150-120}{\sqrt{12}}\\\sigma = 8.66\ minutes$

The distribution's standard deviation is 8.66 minutes.
