Answer:
<em>x = 30°, and y = 46°</em>
Step-by-step explanation:
If we take a look at the attachment below, we will find x = 30°, and y = 46°;
You just take the number and for each whole number, that's 100 % if there is decimals, you take while percent . tens. hundreads....
Answer:
Step-by-step explanation:
The mean of a discrete variable is found by pairing your x values with p(x) values. The summation formula looks like this:

Just in case that jogs your memory. But what I do is I go through one by one, take my first x value and multiply it by my first p(x) value, take my second and multiply those, etc. Create pairs then add all of that up like this:
E(x) = (0)(0.2) + (1)(0.2) + (2)(0.15) + (3)(0.15) + (4)(0.15) + (5)(0.1) + (6)(0.05)
E(x) = 2.35
So the expected value of x should be 2.35.
