So first we need to find the probability of rolling the 2 dice and both landing on 6 one time, which because there is a total of 36 total possibilities that could come from rolling 2 dice it would be a 1/36 chance of getting a double 6's on 2 dices, now if we want to do this 3 times in a row we need to multiply are odds by 2 more 36's so it would look like this 1/36*1/36*1/36=1/46656 so you would have a one in 46656 chance of doing this. Ill have to get back to you about the value need to research that up hope this helps for now!
Number of lemonades sold in 90 minutes = 14
3 hours = 3*60=180 minutes
So, number of lemonades sold in 180 minutes =
=28
Hence, the team will sell 28 lemonades in 3 hours.
If he has 484 plants and there are as many rows as there are plants in each row, his field is a square.
The area of a square = (side)^2
In this problem,
Area = 484
side = # of rows
Let's plug our values into the formula above
484 plants = (side)^2
Take the sqrt of both sides.
22 rows = side.
Answer:
Option B) Fail to reject the null hypothesis that the true population mean annual salary of full-time college professors in the region is equal to $127,000.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = $127,000
Sample mean, = $126,092
Sample size, n = 160
Alpha, α = 0.10
Sample standard deviation, σ = $8,509
First, we design the null and the alternate hypothesis
We use Two-tailed t test to perform this hypothesis.
Formula:
Now,
Since,
The calculated t-statistic lies in the acceptance region, we fail to reject and accept the null hypothesis.
Option B) Fail to reject the null hypothesis that the true population mean annual salary of full-time college professors in the region is equal to $127,000.
