Answer:
The four rational numbers between and
can be:
Step-by-step explanation:
The definition of rational numbers is usually a number of the type a/b where b is different from zero, therefore, to choose the numbers that are between -1/2 (= -0.5) and 1/2 (= 0.5) <u><em>it is enough with choose fractional numbers whose dividend is 1 and its divisor is any number greater than 2, either negative or positive,</em></u> in the answer we choose options such as 1/7 or -1/3, but following the guide I give you, you could choose numbers like 1/16, -1/9 or 1/40 if you wish, always respecting the guidelines given for the dividend and the divisor.
The standard deviation is a measure of a collection of values' variance or dispersion. The correct option is B.
<h3>What is a standard deviation?</h3>The standard deviation is a measure of a collection of values' variance or dispersion. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.
For the last summer,
Mean = (140 + 220 + 190 + 180 + 190) / 5 = 920/5 = 184
For this summer,
Mean = (150 + 170 + 150 + 190 + 180) / 5 = 840/5 = 168
Hence, The number of pages in each book varied more last summer than this summer. Thus, the correct option is B.
