Irrational numbers are numbers that are infinite and non- repeating numbers

irrational- pi, square root of 2, etc

rational- anything else.

15. Which of the following distributions is most likely to be uniform?

MAXImum [283]

Answer:

(b) The distribution of the last digits of ID numbers in a sample of 100 college students

Step-by-step explanation:

Uniform Distribution Explanation

In statistics, uniform distribution refers to a type of probability distribution in which all outcomes are equally likely.

The only possibility here is the distribution of the last digits since the last digit can be 0 thru 9 and each is equally likely to appear in a random sample of 100 students

The others can be eliminated

Heights can vary depending on gender, ethnic background etc. In fact heights will follow a normal distribution

Scores can vary, most students will be scoring around the mean follows a normal distribution

GPAs like scores can vary, most students will have GPAs close to the mean GPA so follows a normal distribution

Ken normally leaves work at 5:00 pm, but he is leaving 20 minutes late today. He decides to make up time by taking the toll road

kobusy [5.1K]

Answer:

The correct answer is: $y=\frac{1}{3} x + 20$

Step-by-step explanation:

As stated in the question that x represents the number of minutes his normal commute takes. Here the keyword is normal; in the normal commute, Ken takes side streets instead of the toll road.

However, in this scenario, we have to come up with the equation that takes Ken's commute via toll road.

Ken can travel 3 times faster by taking the toll road (Given), which can be represented in the mathematical terms in terms of x as follows:

$x_{toll\_road}=\frac{1}{3}x$

Without considering Ken getting late, the equation would become the following:

$y=\frac{1}{3} x$ --- (A)

As Ken is leaving late, we have to incorporate that time as well by adding it in the aforementioned equation (A).

In this case, it's 20 minutes; therefore, the equation (A) will become:

$y=\frac{1}{3} x+20$

Hence, the correct answer is $y=\frac{1}{3} x + 20$ .
