It isn't true.
A theoretical field of grass sized 100ft by 10ft will have an area of 1000ft^2.
The correct answer for the question shown above is: Gabriel should use 2 kilograms of compost.
The explanation is shown below:
1. To solve the exercise you must apply the following proccedure:
2. You have that He
wants it to be 2 parts compost to 10 parts potting soil and he
wants to end up with 10 grams of mix. Therefore:
=(2/12)x12 kilograms
=0.166x12 kilograms
=2 kilograms
Long piece: 5x + 3
Short piece: x
Long + Short = Total
5x + 3 + x = 45
6x + 3 = 45
6x = 42
x = 7
Long piece: 5x + 3 = 5(7) + 3 = 35 + 3 = 38
Answer: short = 7 ft, long = 38 ft
Probability is represented as the number of ways for an event to happen over all possible outcomes. For the theoretical probability, there is 1 black spot and 5 total options. Therefore, the probability is 1/5, or 0.20.
For experimental probability, there were 103 times it landed on black out of 500 spins. The probability is 103/500, or 0.206.
Lastly, the multiple choice. The larger sample size you take, assuming a fair spinner, the more likely you are to see results similar to the theoretical probability. This is because the larger sample size taken, the less each individual spin effects the outcome.
The domain? I think I’m not sure.
