Answer:
p(x=0)=0.000008
p(x=1)=0.00176
p(x=2)=0.0576
P(x=3)=0.941192
Step-by-step explanation:
The probability of successfully classifying any given part is 0.98. There are 3 parts in total and the classifications are independent. The random variable is the number correctly classified parts out of the total 3.
{0,1,2,3,}
Right away, mode is not applicable because mode entails the repetition of the same number. No numbers are repeated here.
To find median, you must put the numbers in numerical order. You should get
111, 114, 121, 179, 216, 220, 234, 246
Next, find the middle. In this case, the middle is split between 179 and 216. To find the median, add 179 and 216 then divide by two. You should get 197.5.
To find the mean, add all the numbers then divide by the number of numbers present (in this case there are 8 numbers). You should get 180.125.
Because the median and mean are off, it is safe to say A is the correct choice.

Step-by-step explanation:
This is calculus, but I don't get fractions in the end. To maximize or minimize any function, you need to find the derivative of it, set it equal to 0, then solve for the critical values.
Our given equation is
x + y = 215 and we want to maximize the product, xy. Therefore,
y = 215 - x so its product in terms of x is
x(215-x) which is
. The derivative of this is
215 - 2x. Set it equal to 0 to maximize it.
215 - 2x = 0 so
-2x = -215 and
x = 107.5.
Sub this in to solve for y:
y + 107.5 = 215 and
y = 107.5
The product is 11556.25, not that you need it.
