The lowest number of people at a table is 0.

<h3>What is the lowest number of people at a table?</h3>

A dot plot is a graph that is used to represent the frequency of a data set. The dots in a dot plot represent the frequency of a number. The greater the height of a number, the higher its frequency. A dot plot is also known as a strip plot or a dot chart.

Looking at the dot plot, it can be seen that there are two dots above 2. This means that at two tables there was no one there.

38. Emily is buying some graduation pictures. She pays $25 for the sitting and $15 for each

goldfiish [28.3K]

a. She pays $100 for 5 sheets

b. 25+15x dollars for x sheets

c. 8 sheets

Step-by-step explanation:

Given

Sitting cost = $25

Per sheet picture cost = $15

Let p be the number of sheets of pictures

Then the cost can be written as a function of p

$c(p) = 25+15p$

Now,

<u>a. How much does she pay for 5 sheets of pictures?! </u>

Putting p = 5 in the function

$c(5) = 25 + 15(5)\\= 25+75\\=100$

She will pay $100 for 5 sheets of pictures

<u>b. How much does she pay for "x" sheets? </u>

Putting x in place of p

$c(x) = 25+15x$

<u>c. How many sheets can she buy for $145? </u>

We know the cost now, we have to find p so,

$145 = 25+15p\\145-25 = 25+15p-25\\120 = 15p$

Dividing both sides by 15

$\frac{15p}{15} = \frac{120}{15}\\p = 8$

Hence,

She can buy 8 sheets for $145

Find the measures of each angle in the inscribed quadrilateral.

Marat540 [252]

Answer:

m∠P = 55° , m∠R = 125° , m∠Q = 110° , m∠S = 70°

Step-by-step explanation:

* Lets study the figure

- A circle and inscribed quadrilateral PQRS

- The four vertices of the quadrilateral lie on the circumference

of the circle

∴ PQRS is a cyclic quadrilateral

* Lets revise the properties of the cyclic quadrilateral

- Each two opposite angles are supplementary, that means

the sum of each two opposite angles = 180°

- The measure of the exterior angle = the measure of the

opposite interior angle

* Lets solve the problem

∵ PQRS is a cyclic quadrilateral

∴ m∠P + m∠R = 180° ⇒ opposite angles

∵ m∠P = 5y + 30

∵ m∠R = 15y + 50

∴ 5y + 30 + 15y + 50 = 180 ⇒ add the like terms

∴ 20y + 80 = 180 ⇒ subtract 80 from both sides

∴ 20y = 100 ⇒ divide both sides by 20

∴ y = 5

* Now lets substitute the value of y in each angle to find

their measures

∵ m∠P = 5y + 30

∴ m∠P = 5(5) + 30 = 25 + 30 = 55°

∵ m∠R = 15y + 50

∴ m∠R = 15(5) + 50 = 75 + 50 = 125°

∵ m∠Q = y² + 85

∴ m∠Q = 5² + 85 = 25 + 85 = 110°

∵ ∠S is opposite to ∠Q

∴ m∠S + m∠Q = 180° ⇒ opposite angles in the cyclic quadrilateral

∴ m∠S + 110 = 180 ⇒ subtract 110 from the both sides

∴ m∠S = 70°

* The measures of the angles are

m∠P = 55° , m∠R = 125° , m∠Q = 110° , m∠S = 70°
