Answer:
0.050328
Step-by-step explanation:
Given that there are 10 coins, out of which 9 are fair and one is double headed.
P(selecting fair coin) = 0.9 and P(selecting double headed coin) = 0.1
P(H/fair coin)= 0.5 and P(H/doube headed ) = 1
Probability of getting in 1 toss head = Prob of selecting fair coin and getting head+ Prob of selecting double headed and getting head
=
This will be constant p for 10 trials going to be done because coin is replaced each time.
Also there are only two outcomes
X no of heads in 5 flips is Binomial with (5, 0.55)
P(x=5) = Reqd probability
=
Answer:
x = 60°
Step-by-step explanation:
46 Yards or 184 Orders of 1/4 Cubic Yards
So first you need to find the area of the plot; 552. Then you need to find out how much soil you will need. There are 12 inches in a foot so if you have 3 inches you have .25 of a foot. So you multiply 552 by .25 and get 138. 138 is how many cubic feet you need. Therefore, you need to divide this number by 3 in order to convert this to yards (3 feet in a yard). This will bring you to 46. Finally, we need to multiply this number by 4 because they only sell in 1/4 cubic yards.

4x10=40
12x7.50=90
6x20=120
5x10=50
18x1=18
40+90+120+50+18=$318.00 deposit
6x+2y=9
Solve for y
2y = 9 - 6x
y = -3x + 4.5
