Cant help you with the probability
To subtract integers, all you have to do is change the sign on the integer that is to be subtracted. If both signs are positive, then our answer will be positive. If both signs are negative, then our answer will become negative. If the signs are different then you are going to want to subtract the smaller absolute value from the larger absolute value.

Answer:
<em> Linear model
</em>
The function f(x) which represents the total amount in the savings account in x months is given by: f(x)=25x+2000
Step-by-step explanation:
Given:
Enrico deposited $2000 in a savings account.
Each month he will deposit additional $25.
This shows that the rate at which the amount is increasing each month is constant.
Therefore, the model will be linear with a slope 25.
So , if x represents the number of months.
and f(x) represents the corresponding amount in the account.
Then the function f(x) is given by: f(x)=25x+2000
Answer:
sin x = -0.8
x = -53.13010235 (used inverse of sin)
tan 2x
tan -106.2602047
= 0.61854704132
