Part A:
First, we will need to compute the area of the lawn.
We are given that the lawn is a rectangular plot with dimensions 60 ft and 90 ft.
Area of rectangle = length * width
Area of lawn = 60 * 90 = 5400 ft^2
Now, we will compute the number of ounces.
We are given that:
<span>Each ounce of grass seed will cover 120 square feet. Therefore, to know the number of ounces needed to cover 5400 square feet, all we have to do is cross multiplication as follows:
1 ounce ---------> 120 square feet
?? ounce --------> 5400 square feet
Number of ounces needed = (5400*1) / (120) = 45 ounces
Part B:
We know that one ounce is equivalent to 0.0625 pounds.
For the lawn, we need 45 ounces, this means that:
number of pounds needed for the lawn = (45*0.0625) / (1) = 2.8125 pounds
which is approximately 3 pounds.
We know that each bag weighs one pound, therefore:
number of bags needed = 3 bags
Hope this helps :)

The expected value of the outcome of the bid is $0.18
So let's start by counting how many bids are placed up to a total of 160.
100*160 = 16000.
What will be your arbitrary bid? As each bid has an equal chance of success, the average of all bids is used. (One cent plus 160 dollars) / 2 = 80 dollars (rounded)
Your odds of winning are 1/16000 (1 bid out of 16000).
If you win, your profit is 1920 ($2000 minus $80.00).
1920/16000 is $0.12
Your cost to enter the auction is $1, and your average winning offer is $0.12.
The result is $0.18 (0.12-1=-0.88).
Thus the expected value of the outcome of the bid is $0.18

Answer: 0.819
Step-by-step explanation:
Given: X is a normally distributed random variable with mean 95 and standard deviation 3.
Then, the probability that X is between 89 and 98 will be:
Hence, the required probability = 0.819
Answer: L=13
Step-by-step explanation: Multiply your eight and five...
5•8=40
Then...Divide forty by two-hundred-fifty...
250/40=13.
You ALWAYS want to check your answer by multiplying to see if you are absolutely correct.
So...5•8•13=250.
Your answer is...Length = 13.
I hope this helps you!
They cant be equivalent since neither of them are a equation. they are just plain t=8 or t=10. t cant be both 8 and 10.
