Answer: probability sampling
Step-by-step explanation:
Probability sampling is used as a sampling method in which the researcher chooses samples from a large population using a method which is based on the theory of probability. For an item to be qualify as a probability sample, that item must be selected using a random selection. An example is the selection of 2 girls from a group of 20 students where 12 are girls and 8 are boys.
Hi Lania!
If Koby can work 22 math problems in 30 minutes, then he can work 44 in an hour (multiply your problems completed and time elapsed by 2).
Now, we have to figure out how many he can complete in 3 hours, so all we have to do is multiply our current math problems by 3.
44 * 3 = 132
This means that Koby can complete D.) 132 math problems in 3 hours.
I hope this helps!
Answer:
10 feet.
Step-by-step explanation:

h^2 = 6^2 + 8^2
h^2 = 100
h = 10 feet.
