<h3>Given :-</h3>

We have given some information in the above table

We have to find the mean, median and mode of the given data.

<h3>Let's Begin :-</h3>

For completion of table you should know the basics formulas :-

For calculating x( mid point)

$\sf{=}{\sf{\dfrac{Sum \:of\: class \:interval }{ 2}}}$

That is,

$\sf{=}{\sf{\dfrac{ = 18 + 25}{2}}}$

$\sf{=}{\sf{\dfrac{ = 43}{2}}}$

$\sf{= 21.5 }$

[ For more calculation ,Please refer the attachment ]

For calculating fx
Multiply frequency and midpoint

$\sf{ fx = frequency {\times} midpoint }$

$\sf{ fx = 8 {\times} 21.5 }$

$\sf{ fx = 172 }$

[ For more calculation please refer the attachment ]

We have to calculate mean, median and mode of the given data

We know that the,

Mean = Sum of all observation / no. of observation

That is

$\sf{ Mean = }{\sf{\dfrac{ {\sigma}fx}{{\sigma}x}}}$

Subsitute the required values,

$\sf{ Mean = }{\sf{\dfrac{ 1811 }{ 187.5}}}$

$\sf{ Mean = 9.65}$

Hence, The mean of the given data is 9.65

<h3>For Median </h3>

We know that, For odd numbers

$\sf{ Median = l + }{\sf{\dfrac{ (n/2 - c)}{ f}}}{\sf{ h }}$

Here,

$\sf{ n = }{\sf{\dfrac{ 50 + 1}{ 2}}}$

$\sf{ n = }{\sf{\dfrac{ 50 }{ 2}}}$

$\sf{ n = 25 }$

Lower limit = 34
c = 20
f = 14
h = 41 - 34 = 7

Subsitute the required values in the above formula :-

$\sf{ Median = 34 + }{\sf{\dfrac{ (25-20)}{ 14}}}{\sf{ 7 }}$

$\sf{ = 34 + }{\sf{\dfrac{ 5}{ 14}}}{\sf{ {\times}7 }}$

$\sf{ = 34 + }{\sf{\dfrac{ 35}{ 14}}}$

$\sf{ = 34 + 2.5}$

$\sf{ = 36.5 }$

Hence, The median of the given data is 36.5 .

We know that,

$\sf{ M= l }{\sf{\dfrac{ (f1 - fo)}{ 2f1 - fo - f2 }}}{\sf{ {\times} h }}$

lower limit = 34
f1 = 14
fo = 12
f2 = 12
H = 7

Subsitute the required values,

$\sf{ M= 34 }{\sf{\dfrac{ (14 - 12)}{ 2(14)- 12 - 12 }}}{\sf{ {\times} 7 }}$

$\sf{ M= 34{\times}}{\sf{\dfrac{ 2}{ 28 - 24 }}}{\sf{ {\times} 7 }}$

$\sf{ M= 34{\times}}{\sf{\dfrac{ 2}{ 4 }}}{\sf{ {\times} 7 }}$

$\sf{ M= 34{\times}}{\sf{\dfrac{ 1}{ 2 }}}{\sf{ {\times} 7 }}$

$\sf{ M= 34{\times}}{\sf{\dfrac{ 7}{ 2 }}}$

$\sf{ M= 34 + 3.5 }$

$\sf{ M= 37.5 }$

So, 

Mode = 37.5

Hence ,The mode of the given data is 37.5 .

Marlene rides her bike at a rate of 16 miles per hour. The time in hours that she rides is represented by the variable t, and th

White raven [17]

Let

t--------> the time in hours

d-------> the distance in miles

we know that

$d=16t$

this is a linear equation that represent the scenario

in this equation the independent variable is the time t and the dependent variable is the distance d

The distance's equation in function notation is equal to

$f(t)=16t$

Using a graph tool

see the attached figure

The domain of the function is the interval----------> [0,∞)

$t\geq0$

The range of the function is the interval-------> [0,∞)

$f(t)\geq0$

Statements

a) The independent variable, the input, is the variable d, representing distance

The statement is false

Because the independent variable is the variable t

b) The distance traveled depends on the amount of time Marlene rides her bike

The statement is true

Because the distance's equation in function notation is equal to

$f(t)=16t$

c) The initial value of the scenario is 16 miles per hour

The statement is false

Because $16$ represent the rate or the slope of the linear equation

d) The equation t = d + 16 represents the scenario

The statement is false

Because, the scenario is represented by the function $f(t)=16t$

e) The function f(t) = 16t represents the scenario

The statement is true
