Step-by-step explanation:

A box plot is the diagrammatic representation of the five number summary. It includes 5 items:

The minimum.

Q1 = the first quartile or the 25% mark.

The median.

Q3 = the third quartile or the 75% mark.

The maximum.

Rearranging the data in ascending order, it becomes

169, 163, 153, 166, 149, 148, 146, 145, 152, 163

145, 146, 148, 149, 152, 153, 163, 163, 166, 169

Minimum = 145

Maximum = 169

Median = (152 + 153)/2 = 152.5

The median divides the data into two equal halves. The middle of the lower halve is Q1 while the middle of the upper halve is Q3

Q1 = 148

Q3 = 163

The diagram of the box plot is shown in the attached photo

The number of seats in each row of a theater forms an arithmetic sequence. The fifth row contains 22 seats. The tenth row contai

beks73 [17]

Let $s_n$ denote the number of seats in the $n$ -th row. $s_n$ is arithmetic, so

$s_n=s_{n-1}+d$

for some constant $d$ .

We're told $s_5=22$ and $s_{10}=37$ , so that

$s_{10}=s_9+d$

$s_{10}=(s_8+d)+d=s_8+2d$

$s_{10}=(s_7+d)+2d=s_7+3d$

and so on up to

$s_{10}=s_5+5d\implies37=22+5d\implies5d=15\implies d=3$

The pattern continues:

$s_5=s_4+3$

$s_5=(s_3+3)+3=s_3+2\cdot3$

and so on up to

$s_5=s_1+4\cdot3\implies22=s_1+12\implies\boxed{s_1=10}$

Subtract 2 from both sides and you get 2x>2, dived 2 from both sides to isolate the variable. Then you get x>1 :)
