Alborosie
We can rewrite the asked question like this:
E(X_1-X_2)
wherein X_1 and X_2 are random variable with the same given  normal distribution. Then mean of (X_1-X_2) is zero and the variance 
can be computed like this: 4.8+4.8=9.6
So, the random variable X_1-X_2 follows a normal distribution 
with means 0 and standard deviation 9.6. 
The median of the law N(0,9.6) is 0. 
So the expected difference of the score is 0.

jolli1 [7]
Use the attached formula.
exp = [log (total / principal) / n*years]
where "n" is compounding periods per year
exp = [log (7,194.66 / 2,978.41) / (365*21)
exp = log ( <span> <span> <span> 2.4156042989 </span> </span> </span> ) / 7,665
exp = log ( <span> <span> 2.4156042989 </span> </span> ) / 7,665
exp = 0.38302579382 / 7,665
exp = <span> <span> <span> 0.00004997074935681670 </span> </span> </span>

rate = (10^exp -1)* n
rate = (10^<span>0.00004997074935681670 -1) * n
</span>rate = <span><span>(1.0001150685 </span> -1) * 365
</span>rate = <span>(.0001150685) * 365</span>
rate = <span> <span> <span> 0.0420000025 </span> </span> </span>
rate = <span>4.20000025 %
rate = 4.2 %

Yes, it's just that easy.  LOL

Jim needs to rent a car. A rental company charges $21 per day to rent a car and $0.10 for every mile driven. He will travel 250
ANTONII [103]

Answer:

Step-by-step explanation:

Let x represent the number of days for which Jim wants to rent the car.

The rental company charges $21 per day to rent a car and $0.10 for every mile driven. He will travel 250 miles. It means that the cost of travelling 250 miles in x days is expressed as

21x + 0.1 × 250

= 21x + 25

If he has $115 to spend, then the inequality that can be used to determine the maximum number of days that Jim can rent a car is

21x + 25 ≤ 115
