Answer:
0.40
Step-by-step explanation:
to find out the probability that at least one of a pair of fair dice lands of 5, given that the sum of the dice is 8
Let A = sum of dice is 8
B = one lands in 5
P(B/A) = P(AB)/P(A) by conditional probability
P(AB) = sum is 8 and one is 5
So (5,3) or (3,5)
P(A) = sum is 8.
i.e. (2,6) (2,6) (3,5) (5,3) (4,4)
Required probability
= n(AB)/n(A)

Answer:
Martha earns $65.6 over the weekend.
Step-by-step explanation:
Brownies sold by Martha on Saturday = 60
Cookies sold by Martha on Saturday = 42
Brownies sold by Martha on Sunday = 28
Cookies sold by Martha on Sunday = 54
Total brownies sold by Martha over the weekend = 
Total cookies sold by Martha over the weekend = 
Cost of a brownie = $0.20
Cost of a cookie = $0.50
Total cost of brownies sold over the weekend = 
Total cost of cookies sold over the weekend = 
∴ Total money Martha earned over the weekend =

Answer: the difference between the max is 3200.
Step-by-step explanation:
20000-16800= 3200
Step-by-step explanation:
Perimeter of a rectangle = 2(L+W)
L is the length of the rectangle:
W is the width of the rectangle.
Given
Perimeter = 214feet
If the length is 41 ft longer than the width, then L = 41+W
Substitute L = 41+W into the formula:
P = 2(L+W)
214 = 2(41+W+W)
214 = 2(41+2W)
214 = 82+4W
4W = 214-82
4W = 132
W = 132/4
W = 33 feet
Since L = 41+W
L = 41+33
L = 74 feet
Hence the dimension of the field is 74ft by 33ft
<em>The width of the playing field is 33feet</em>
