[A+7= 28] is the correct equation I believe, though I may be wrong.
Answer:
The expected value of lateness
hours.
Step-by-step explanation:
The probability distribution of lateness is as follows:
Lateness P (Lateness)
On Time 4/5
1 Hour Late 1/10
2 Hours Late 1/20
3 Hours Late 1/20
The formula of expected value of a random variable is:

Compute the expected value of lateness as follows:


Thus, the expected value of lateness
hours.
Hi there!
Since we know that the pancake mix has 5% of the daily allowance, which is 300 mg, we can just multiply 300 mg with 5 percent to get our answer.
First, let's divide 5% by 100% to know what we are going to multiply 300 mg with.
5% / 100% = 0.05
Let's multiply 300 mg with 0.05
0.05 * 300 = 15 mg
Thus, a 1/2 cup of pancake mix has 15 mg of cholesterol.
Have an awesome day! :)
