Answer:
11
Step-by-step explanation:
The lines on the outside simply means "absolute value". This just takes any negative number and makes it positive. In this case, 15-4 is already positive so the answer is just positive 11.
36.96 with the formula 0.24 * 154 = 36.96
Answer:
So the decay percentage rate is of 70.8%
Step-by-step explanation:
An exponentil function has the following format:
In which c is a constant.
If a>1, we have that a = 1 + r and r is the growth rate.
If a<1, we have that a = 1 - r and r is the decay rate.
In this problem:
a = 0.292
A is lesser than 1, so r is the decay rate.
1 - r = 0.292
r = 1 - 0.292
r = 0.708
So the decay percentage rate is of 70.8%
There is 1/5000 chance to win first place of $2000,
1/5000 chance to win second place of $500
3/5000 chance to win third place of $100
10/5000 chance to win the consolation prize of $25.
The ticket costs $1.
We multiply each probability by the amount, and subtract the ticket cost, to get the expected net earnings:
(1/5000)($2000) + (1/5000)($500) + (3/5000)($100) + (10/5000)($25) - $1 = $(-0.39).
This means that there is an expected loss of $0.39.
