Average number of jumps on lowest bar = 3/2 = 1.5
Average number of jumps on middle bar = 6/4 = 1.5
Average number of jumps on highest bar = 4/1 = 4
Overall average number of jumps = 3/2 + 6/4 + 4/1 = 7
Overall average number of jumps =
+ 1/probability of complete the lowest bar
+1/probability of complete the middle bar
+ 1/probability of complete the highest bar
Equations of Shane’s overall average number of jumps completed = x * (7/13), where x is the total number of overall jumps.

Answer:
i think maybe 1 a minute and 60 an hour? sorry if im wrong im not super great at math
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
L = length
W = 2 feet less than L = L-2
Area = L x W
20 = L * (L-2)
20 = L^2 - 2L
0 = L^2 - 2L - 20
Use Quadratic Formula a = 1 b = -2 c = -20
L = [-b ± sqrt(b^2-4ac) ]/2a
to calculate <u> L = 5.5826 ft then W = L-2 = 3.5826 ft </u>

Step-by-step explanation:
Answer:
ice cream = 3.80$
cup cake = 4.25$
donuts = 2.5$
Step-by-step explanation:
a=ice cream
b = cup cake
c = donuts
we can write the following equations given from the picture:
a+b+b=12.30$ equation 1
b+c+a=10.55$ equation 2
b+c+c =9.25$ equation 3
using equation 1 we have:
2b+a=12.30
a=12.30-2b
using equation 3 we have:
2c+b=9.25
c=(9.25-b)/2
using equation 2 we have:
b+((9.25-b)/2)+12.30-2b=10.55
((2b+9.25-b)/2) - 2b = 10.55-12.30
((2b+9.25-b-4b)/2) =-1.75
-3b+9.25=2*(-1.75)
-3b= -3.5-9.25
-3b=-12.75
b=12.75/3
so we have b= 4.25$ = cup cake
we have:
c=(9.25-b)/2= (9.25-4.25)/2
c=2.5$= donuts
a= 12.30-2b= 12.30-2*(4.25)
a= 12.30-8.5 = 3.8$ = ice cream
