Three rational numbers between 5/31 and 6/31
Ludmilka [50]

Answer:

\dfrac{26}{155}, \dfrac{27}{155}, and \dfrac{28}{155}.

Step-by-step explanation:

What is a rational number? By definition, a rational number can be represented as the fraction of two integers.

The goal is to find three fractions in the form \dfrac{p}{q} between \dfrac{5}{31} and \dfrac{6}{31}.

\dfrac{5}{31} < \dfrac{p}{q} < \dfrac{6}{31}.

At this moment, there doesn't seems to be a number that could fit. The question is asking for three of these numbers. Multiple the numerator and the denominator by a number greater than three (e.g., five) to obtain

\dfrac{25}{155} < \dfrac{p}{q} < \dfrac{30}{155}.

Since p and q can be any integers, let q = 155.

\dfrac{25}{155} < \dfrac{p}{155} < \dfrac{30}{155}.

\implies 25 < p < 30.

Possible values of p are 26, 27, and 28. That corresponds to the fractions

\dfrac{26}{155}, \dfrac{27}{155}, and \dfrac{28}{155}.

These are all rational numbers for they are fractions of integers.

In 2001 polls indicated that 74% of Americans favored mandatory testing of students in public schools as a way to rate the schoo
Kryger [21]

Answer:

The right answer is:

"If 74% of Americans still favor mandatory testing this year, then there is a 1.5% chance that poll results will show 71% or fewer with this opinion."

Step-by-step explanation:

The P-value represents the probability of getting the sample we got, given that the null hypothesis is true. For this reason, it the P-value is lower than the significance level, it means that the sample result is unlikely due to chance, but due to a false null hypothesis.

In this case, the P-value represents a probability P=0.015 of having a sample with proportion p=0.71, given that the population has a proportion π=0.74.

The right answer is:

"If 74% of Americans still favor mandatory testing this year, then there is a 1.5% chance that poll results will show 71% or fewer with this opinion."

Find the surface area of the triangular prism below.
Lapatulllka [165]

Step-by-step explanation:

At first you need to take its lateral surface area by using the perimeter of base of the triangle and the height of prism.

Then after calculating it you need to find out its total surface area which is asked in the question and that is calculated by adding the area of both triangles of the prism in the lateral surface area.

Then that's your answer.
