The average building height and the standard deviation for two separate cities' samples are shown. The true statements are:

City A’s heights are more spread out than city B’s heights.

City A has a lower average height than city B.

<h3>What is average?</h3>

In daily life, an average is a number chosen to represent a group of numbers; it is often the sum of the numbers divided by the total number of numbers in the group (the arithmetic mean). The average of the integers 2, 3, 4, 7, and 9, for instance, is 5, which equals 25. An average could alternatively be another statistic like the median or mode, depending on the situation. The median is sometimes used in place of the mean since the mean would be unnaturally high if it included the personal incomes of a few billionaires. The median is the amount below which 50% of personal incomes fall and above which 50% of personal incomes rise.

andrezito [222]

Answer:

g(4) = 18

Step-by-step explanation:

You have to input 4 in the x poistion of the equation :

g(x) = x² - 6/3x + 10

Solve:

g(4) = 4² - 6/3(4) + 10

=> Multiply and distrubute

g(4) = 16 - 8 + 10

=> Smplify

g(4) = 18

likoan [24]

In order to construct a scatter plot, the essential items include;

A: The variable measured on the vertical axis. This is because the variables on both axes is the major reason why the graph is being constructed, so the variable must be identified.

B: The variable measured on the horizontal axis, for the same reason as stated above.

D: The scale of vertical and horizontal axes. This helps to read off the range of the data set without going beyond the limit
