I need the function for this im very confused
1 answer:
Answer:
The Function would be .
Step-by-step explanation:
Given:
Time worked in (hrs) = 'h'
Earnings ($) = 'E'
Also Table is given:
Total Worked (hrs) Earnings($)
10 65
11 71.50
12 78
13 84.50
We need to find the function for this table.
Now we will first find the earnings for 1 hour.
For 10 hrs = $65
So for 1 hr = Amount of earnings for 1 hr.
By Using Unitary method we get;
Amount of earnings for 1 hr =
Hence We can say that;
Hence the Function would be .
We will check for the table using this function we get;
when h = 10
when h = 11
when h = 12
when h = 13

Answer:
The probability function of X and Y is
With k in {1,2,3,4,5,6}
Step-by-step explanation:
We can naturally assume that X and Y are independent. Because of that, P(X=a, Y=b) = P(X=a) * P(Y=b) for any a, b.
Note that, since the die is honest, then P(X=k) = 1/6 for any k in {1,2,3,4,5,6}. We can conclude as a consequence that P(X=k, Y=l) = P(Y=l)/6 for any k in {1,2,3,4,5,6}.
Y has a binomial distribution, with parameters n = 3, p = 1/2. Y has range {0,1,2,3}. Lets compute the probability mass function of Y:
Thus, we can conclude that the joint probability function is given by the following formula
For any k in {0,1,2,3,4,5,6}
