Answer: 12.5%

Step-by-step explanation:

Given: A set of data representing the heights of 16 students, in centimeters, is shown in the histogram below.

Therefore, the total frequency of students  = 16

From the histogram, the frequency of students having height between 160 and 169 cm=2

The percent of students are between the heights of 160 and 169 centimeters is given by :-

P=\frac{\text{Frequency of students having height between 160 and 169 cm}}{\text{Total frequency}}\times100\\\\\Rightarrow\ P=\frac{2}{16}\times100\\\\\Rightarrow\ P=12.5\%

Hence, the  percent of students are between the heights of 160 and 169 centimeters = 12.5%

Answer:

m∠R = 112°

m∠S = 112°

m∠T = 68°

Step-by-step explanation:

Quadrilateral QRST is a cyclic quadrilateral.

A <u>cyclic quadrilateral</u> is a quadrilateral drawn inside a circle where every vertex touches the circumference of the circle.  

The <u>opposite angles</u> in a cyclic quadrilateral sum to 180°.

⇒ m∠Q + m∠S = 180°

⇒ m∠R + m∠T = 180°

Given:

  • m∠Q = 68°
  • m∠R = (3x + 40)°
  • m∠T = (5x - 52)°

<u>Measure of angle Q</u>

⇒ m∠Q + m∠S = 180°

⇒ 68° + m∠S = 180°

⇒ m∠S = 180° - 68°

⇒ m∠S = 112°

<u>Measure of angles R and T</u>

⇒ m∠R + m∠T = 180°

⇒ (3x + 40)° + (5x - 52)° = 180°

⇒ )8x -12)° = 180°

⇒ 8x° = 192°

⇒ x = 24

Substituting the found value of x into the expressions for angles R and T:

⇒ m∠R = (3(24) + 40)°

⇒ m∠R = 112°

⇒ m∠T = (5x - 52)°

⇒ m∠T = 68°

Which of the following expressions shows how to rewrite 5 − 6 using the additive inverse and displays the expression correctly o
Andru [333]

The correct display of the expression on a number line is number line (c)

<h3>How to determine the expression that shows how to rewrite 5 − 6 using the additive inverse?</h3>

The complete question is added as an attachment

The expression is given as:

5 - 6

Put 6 in a bracket.

So, we have:

5 - 6 = 5 - (6)

Express 6 as --6

So, we have:

5 - 6 = 5 - -(-6)

Rewrite as:

5 - 6 = 5 + (-6)

The above means that the arrow on the number line must start from 5 and moves in the negative direction in 6 units

The correct display of the expression on a number line is number line (c)
