Answer:
E= 3/20
Step-by-step explanation:
Number of blue disk= 3
Number of green disk= 3
Number of orange disk= 4
Total number of disk = 3+3+34
= 10
Let B represent blue disk
Let G represent green disk
Let O represent orange disk
If three disk are selected at random, the possible outcome of one green disk and two orange disks are
OOG, OGO, GOO
Pr(OOG) = Pr(O1) * Pr(O2) * Pr(G3)
= 4/10 * 3/9 * 3/8
= 36/720
= 1/20
Pr(OGO) = Pr(O1) * Pr(G2) * Pr(O3)
= 4/10 * 3/9 * 3/8
= 36/720
= 1/20
Pr(GOOG) = Pr(G1) * Pr(O2) * Pr(O3)
= 4/10 * 4/9 * 3/8
= 36/720
= 1/20
Pr(total) = Pr(OOG) + Pr(OGO) + Pr(GOO)
= 1/20 + 1/20 + 1/20
= 3/20
R = 8.5%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation
r = (1/2)((20475/17500) - 1) = 0.085
r = 0.085
converting r decimal to a percentage
R = 0.085 * 100 = 8.5%/year
The interest rate required to get
a total amount, principal plus interest, of $ 20,475.00
from simple interest on a principal of $ 17,500.00
over 2 years is 8.5% per year.

Answer:
33 i think
Step-by-step explanation:
Answer:
23.6 (approximate value)
Step-by-step explanation:
- a*a+b*b=c*c Pythagorean thereom
- (21.5)^2 + b*b = (31.9)^2
- b*b= 1017.61 - 462.25
- √b*b= √555.36
- b=23.6(approximate value)
