Arestaurant offers hamburgers with one, two, or three patties. let x represent the number of patties a randomly chosen customer orders on their hamburger. based on previous data, here's the probability distribution of x along with summary statistics:

x=# of patties 1 2 3
p(x) 0.40 0.50 0.10
mean: μx=1.7
standard deviation: σx≈0.67
the total price of each burger is set at $2 per patty. let t represent the total price a randomly chosen customer pays for their burger. find the mean of t

The mean price a randomly chosen customer pays for her or his burger is US$ 3.40

Step-by-step explanation:

Let's find out the mean of T (total price a randomly chosen customer pays for their burger), this way:

Mean of T = 0.4 * $ 2 + 0.5 * $ 4 + 0.1 * $ 6

Mean of T = 0.8 + 2 + 0.6

Mean of T = US$ 3.40

The mean price a randomly chosen customer pays for her or his burger is US$ 3.40

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
