A vending machine operator has determined that the number of candy bars sold per week by a certain machine is a random variable

docker41 [41]

Answer:

The answer is below

Step-by-step explanation:

Let Y represent the profit per day, and x represent the number of bar sold per day. Hence:

Y = 0.25x - 2

a) The mean is given as:

$\mu_y=E(Y)=E(0.25X-2) = 0.25E(X)-2\\\\But\ E(X)=mean\ of\ machine=125. Hence:\\\\E(Y)=0.25(125)-2=29.25\\\\E(Y)=\$29.25$

b) The standard deviation of y is:

$\sigma_y=var(0.25X-2)\\\\\sigma_y=0.25\sigma(X)\\\\but\ \sigma_X=7,hence:\\\\\sigma_y=0.25(7)=1.75\\\\\sigma_y=\$1.75$

Marizza181 [45]

Answer:

5525

Step-by-step explanation:

Using the formula with n = 25 , then

Please solve for me ill give brainliest

Answer:

$\displaystyle (0, -1); maximum$

Step-by-step explanation:

First off, B is zero, so there is no phase shift, meaning that the vertex stays on the y-axis. Next, A is negative, so the parabola opens down, and whenever you have a parabola opening down, it does so at maximum. Finally, C represents our y-intercept, or in this case, our vertical shift. Our y-intercept is (0, −1), and so as our vertex, hence our answer.
