The answer to your question is 10 2/5
You can solve this by algebraically as well as graphically. When I tried both ways I got:
solution is x= -2<span />
1-2. The best estimate for the population mean would be sample mean of 60 gallons. Since we know that the sample mean is the best point of estimate. Since sample size n=16 is less than 25, we use the t distribution. Assume population from normal distribution.
3. Given a=0.1, the t (0.05, df = n – 1 = 15)=1.75
4. xbar ± t*s/vn = 60 ± 1.75*20/4 = ( 51.25, 68.75)
5. Since the interval include 63, it is reasonable.
If you want to solve for x
-5x-4=?
add 4 to both sides
-5x=4+?
divide both sides by -5
x=(4+?)/-5
x=-(4+?)/5
In 12 turns, she lands in a blue space 3 times.
12/3 =4
In 100 turns, it is expected that Myra would land on a blue space '100/4' times
100/4= 25
Which sums up to 25 turns
