Answer:
14 people
Step-by-step explanation:
- A sample is defined as a set of objects or people selected by a given criteria to be studied.
-The sample's elements are unknown pre-study.
-In this case the group of 30 is the population and the 14 people is the sample.
Answer:
12 miles
Step-by-step explanation:
Let the amount of hours it takes Leroy to catch up to Kevin equal x. Since speed multiplied by time is distance, Leroy would have run a total of 6x miles(6*x). Kevin already had a head start of 24 minutes, which is the same as 2/5 of an hour. In 2/5 an hour, Kevin ran 2 miles as 2 is 2/5 *5. For the next x hours his distance would be a total of 5x(5*x). This means, after x hours, Kevins distance is 5x + 2. In this case, catching up to someone is the same as having the same distance value. This means we can set the two expressions equal to each other, and solve:
6x = 5x + 2
x = 2
The time it took Leroy to catch up is 2 hours, but we are looking for the distance, which is represented by 6x. We substitute in 2 to get:
6(2) = 12
This means Leroy had to run 12 miles.
Domain ( all possible values of x) is x > 5 or in interval notation it is (5, ∞)
The range( all possible values of log x) is (-∞, ∞)
Answer:
1/4 to the 3rd power is 0.015625
Step-by-step explanation:
Im assuming that is what your asking, you worded it a little differently. When you figure out what the value of something is based on the power it is raised to, you multiply that number by itself the amount of the exponent.
1/4 x 1/4 x 1/4 = 0.015625
