Sequence = 40, 45, 48, 51, 59, 62, 69, 74

Median = 51+59 / 2 = 55
First quartile = 40, 45, 48, 51 
So, it would be: 45 + 48 / 2 = 46.5

In short, Your Answer would be Option C

Hope this helps!

I SUCK AT MATH PLEASE HELP
sergeinik [125]

Answer:

1. -1/28

2. -4

3.A) The attendance increased by an average of 25 people per game from game 2 to game 5.

4. -.125

Step-by-step explanation:

To find the rate of change, we use the formula

f(x2) - f(x1)

--------------

x2-x1

1.  

f(x) = -(x) ^ 1/3

f(64) = -(64) ^ 1/3 = -4

f(8) =- (8)^1/3 = -2

f(64) - f(8)     -4--2             -4+2             -2            -1

-------------- = ---------     =  ------------- = ----------- =  ------

64 - 8              56               56              56            28

2.  

f(2) = 9

f(-2) = 25

f(x2) - f(x1)   f(2) - f(-2)      9-25              -16            -16

-------------- =----------- = ----------------- = ---------- = ----------- = -4

x2-x1             2--2                2+2              4            4

3.

f(5) = 755

f(2) = 680

f(x2) - f(x1)    f(5) - f(2)     755-680      75

-------------- = ----------   = -------------- = ---------- = 25

x2-x1              5-2                  3             3

A) The attendance increased by an average of 25 people per game from game 2 to game 5.

4.  

f(-1)  = -.25

f(1) = -.5

f(x2) - f(x1)    f(1) - f(-1)     -.5 --.25       -.5+.25     -.25

-------------- = ----------   = -------------- = ---------- = --------- = -.125

x2-x1              1--1                 1+1             2             2

If the domain of f(x)=-x² is integer values of x such that -3≤x&lt;0, find the range.
slamgirl [31]

The range is the resulting y-values we get after substituting all the possible x-values.

\text{The domain:}\\\\-3\leq x < 0\to\{-3,\ -2,\ -1\}\\\\\text{The range:}

Substitute the values of x to the equation of the function:

f(-3)=-(-3)^2=-9\\\\f(-2)=-(-2)^2=-4\\\\f(-1)=-(-1)^2=-1\\\\\boxed{\{-9,\ -4,\ -1\}}
