Answer:

Down the left-hand column, the pattern is counting by 5's. Therefore, 5, 10, 15, 20, 25. Down the right-hand column, the pattern is counting by 4's. Therefore, 4, 8, 12, 16, 20. Thus, the ratios are:

5:4

10:8

15:12

20:16

25:20

In other words, the first line (5:4) is the base ratio. The second line multiplies the original values by 2, the third line by 3, the fourth line by 4, and the fifth line by 5.

The first quartile of a data set is 72, and the third quartile is 92. Which of these values in the data set is an outlier? A.61
marishachu [46]
IQR = Q3 - Q1 = 92 - 72 = 20
20 * 1.5 = 30

72 - 30 = 42....outlier is anything below 42
92 + 30 = 122...outlier is anything above 122

so the outlier is 41

Find the maximum/minimum value of the function y = x2 - (5/3)x + 31/36.
AysviL [449]

Answer:

A

Step-by-step explanation:

Given a parabola in standard form, y = ax² + bx + c ( a ≠ 0 ), then

minimum/ maximum value is the y- coordinate of the vertex.

The x- coordinate of the vertex is

x_{vertex} = - \frac{b}{2a}

y = x² - \frac{5}{3} x + \frac{31}{36} ← is in standard form

with a = 1 and b = - \frac{5}{3} , thus

\frac{x}{vertex} = - \frac{-\frac{5}{3} }{2} = \frac{5}{6}

Substitute this value into y

y = (\frac{5}{6} )² - \frac{5}{3} (\frac{5}{6} ) + \frac{31}{36}

   = \frac{25}{36} - \frac{25}{18} + \frac{31}{36} = \frac{1}{6}

Since a > 1 then the vertex is a minimum, thus

minimum value = \frac{1}{6} → A
