Angle 3 would be equivalent to angle 5 which is 100 since they are alternate interior angles. Angle 4 would be the supplement of angle 5 which is 80 because they are same side interior angles

Find the median, first quartile, third quartile, interquartile range, and any outliers for each set of data. 111, 68, 93, 88, 74

lilavasa [31]

Answer:

Q1 = 87 ;

Q2 = 102 ;

Q3 = 115 ;

IQR = 28

OUTLIER = None

Step-by-step explanation:

Given the data:

111, 68, 93, 88, 74, 152, 119, 87, 88, 105, 84, 102, 151, 115, 112

Ordered data : 68, 74, 84, 87, 88, 88, 93, 102, 105, 111, 112, 115, 119, 151, 152

Sample size, n = 15

The first quartile, Q1 = 1/4(n+1)th term

Q1 = 1/4(15+1)th term

Q1 = 1/4(16) = 4th term

Q1 = 87

The Median , Q2 = 1/2(n+1)th term

Q2 = 1/2(15+1)th term

Q2 = 1/2(16) = 8th term

Q2 = 102

The third quartile, Q3 = 3/4(n+1)th term

Q3 = 1/4(15+1)th term

Q3 = 3/4(16) = 12th term

Q3 = 115

The interquartile range, IQR = Q3 - Q1

IQR = (115 - 87) = 28

Q1 = 87 ;

Q2 = 102 ;

Q3 = 115 ;

IQR = 28

OUTLIER = None

A linear function is a function that has constant average rate of change;

Also, a relation that represents a function must have unique input and output values.

<h3>Question 11: Relations and Functions</h3>

A relation may or may not represent a function.

When the domain and the range of a relation are unique, then the relation is a function.

So, the true option is (b) function

<h3>Question 12: Relations and Functions</h3>

A one-to-many relation is not a function.

This is so because the domain and the range of the function are not unique

So, the true option is (c) figure 3: one-to-many.

<h3>Question 13: Variables</h3>

A dependent variable is a variable that depends on other variables for its value.

In this case, the dependent variable is (b) boosts the immune system.

<h3>Question 14 and 15: Domain and Range</h3>

The domain is the set of input values (i.e. the x values), while the range is the set of output values (i.e. the y values)

This means that:

The domain of the function is: (a) {2,3,4,5,6}
The range of the function is: (b) {4,6,8,10,12}

<h3>Question 16 and 17: Linear functions</h3>

The graph of a linear function is represented by a straight line, and it has a constant slope or rate.

This means that:

Graph C is a linear function
Table B is a linear function

<h3>Question 18: The table</h3>

The fare of 3 km and 5 km are given as 35 pesos and 55 pesos, respectively.

This means that:

Table (b) represents the information

<h3>Question 19: The linear equation</h3>

Start by calculating the slope (m) using:

$m = \frac{y_2 -y_1}{x_2 -x_1}$

So, we have:

$m = \frac{55-35}{5-3}$

$m = \frac{20}{2}$

$m = 10\\
$

The linear equation is then calculated as:

$y = m(x -x_1) + y_1$

This gives

$y = 10(x -3) + 35$

$y = 10x -30 + 35$

$y = 10x +5$

This means that:

The linear equation that describes the relationship is (c) $


$ $


$ $y = 10x +5$ ; $x \ge 2$

<h3>Question 20: The fare when the distance is 4km</h3>

This means that x = 4.

So, we have:

$y = 10 \times 4 +5$

$y = 45$

Hence, the fare will be (a) 45 pesos

A researcher wants to study the effect of regular exercise on cholesterol levels. The researcher compares the cholesterol levels

ExtremeBDS [4]

Answer:

b. members of a local gym who exercise regularly have lower mean cholesterol levels than those in the community who do not exercise regularly.

Step-by-step explanation:

From the research, the researcher compared the cholesterol levels of 50 people who belong to a local gym and exercise regularly with the cholesterol levels of 50 people from the community who do not exercise regularly, and found out that the cholesterol levels of the members of the gym were substantially lower. This only proves and ascertain that the members of a local gym who exercise regularly have lower mean cholesterol levels than those in the community who do not exercise regularly. And does not lead to a general conclusion that exercising regularly reduces cholesterol level as there are other variables and data that are not considered/available (such as data on cholesterol levels of people before and after they joined the gym and exercise regularly). Other factors that may affect change in cholesterol levels must also be considered before making a general conclusion on the effect of regular exercise on cholesterol level.
