A fair cube 60 times.
A farmer might want to know the mean number of weeds in three plots of land. This number would be the average number of weeds on the farm. This number can be calculated by adding the number of weeds in all three plots, and then dividing by three.
3x^2 plus 5x
Density is typically the weight of an object divided by its volume. Convenient units are pounds per cubic feet, or grams per cubic centimeter. Density can also refer to number of objects per area (or volume). The population density of a city is the number of inhabitants divided by the land area.
t is the average number of weeds. The average is found by adding the total number of weeds for all three plots, then dividing that total by the number of plots. For example, ifplot #1 has 200 weeds, plot #2 has 180 weeds, and plot #3 has 274 weeds, the mean number of weeds for all three plots would be 218. (200+180+274) divided by 3.
Give them land
You can expect the spinner to land an odd number 25 times out of 50.
I would expect it to land on a number of 4 or higher 50% of the time or roughly 24 times.
If it is a fair die then it is impossible to predict. The expected value is 20.
The answer depends on the number of sides on the spinner and how they are numbered.
40 times
5
Assuming the die is fair, the probability of a number greater than three is a half so the EXPECTATION would be that it will land on a number greater than 3 thirty times. But, this is the expectation; the actual number could be anything from 0 to 60.
about 18...hope this helps(:
27 - if it was a fair die.
That would depend on how many numbers are on the spinner and the cube. The more numbers there are, the less likely it is that they would both land an any given number.
1:4 i think
If a standard number cube or die is rolled, the probability that a 4 does not land face up is five out of six, or (six minus one) out of six.
