A pizza shop delivers only one kind of pizza, which is sold for $ 10 $10dollar sign, 10, and costs the pizza shop $ 6 $6dollar s

ign, 6 to make. The pizza shop has a delivery policy that says if the pizza takes longer than half an hour to arrive, there is no charge. Experience has shown that delivery takes longer than half an hour only 10 % 10%10, percent of the time. Let the random variable X XX be the pizza shop's profit for a randomly selected delivery order for one of these pizzas.

Answer:

$3

Step-by-step explanation:

The probability distribution for X, the pizza shop's profit is given below:

\left|\begin{array}{c|c|c}----&-----&----\\&$Late&$On-Time\\----&-----&----\\$X=Profit&-\$6&\$4\\----&-----&----\\P(X)&0.10&0.90\\----&-----&----\\\end{array}\right|

The mean of X is the expected value of X.

Mean, \mu=(0.10X-6)+(0.90X4)

=-0.6+3.6

=$3

The mean profit of the pizza's shop for a randomly selected delivery order for one of these pizzas is $3.

Answer:

90 degrees

Step-by-step explanation:

Step 1: State what is known

Notice that the 2 lines cut the square in half and create 4 congruant triangles.  We know a full circle is 360 degrees and the intersection is a perfect circle formed by 4 angles.  We can find the angle AEB by dividing 360 by 4 which gives you 90 degrees

Water flows into a tank according to the rate F of t equals the quotient of 6 plus t and the quantity 1 plus t, and at the same
diamong [38]

Answer:

Step-by-step explanation:

The complete question is

Water flows into a tank according to the rate F(t)= (t+6)/(1+t), and at the same time empties out at the rate E(t)= (ln(t+2))/(t+1), with both F(t) and E(t) measured in gallons per minute. How much water, to the nearest galllon, is in the tank at time t=10 minutes.

Let C(t) be the amount of water in the tank at time t. We now that the rate of change of the tank is given by

\frac{dC}{dt}=[\tex]rate at which water flows in- rate at which water flows out. Then [tex]\frac{dC}{dt}=\frac{t+6}{t+1}-\frac{\ln(t+2)}{(t+1)}[\tex]so, the desired expression is obtained by integrating with respect to t. This leads us to [tex]C(t)  = \int \frac{t+1}{t+1}+ \frac{5}{t+1} - \frac{\ln(t+2)}{(t+1)} dt=t+ 5 \ln (|t+1|)-\int \frac{\ln(t+2)}{(t+1)} dt +C

Unfortunately, the integral \int \frac{\ln(t+2)}{(t+1)} dt cannot be expressed using fundamental functions. So, the problem cannot have an specific function (if you are willing to know the complete answer, the integral of this function uses the  polylogarithm function with n=2).

Since you want the exact amount of water at time, you need to give C a value, that is, you need to know an initial condition for the problem. This means, you need to know the amount of water in the tank at time 0
