Answer:
The third graph is correct
Step-by-step explanation:
Hiiii,
Since the sign is < and doesn't have a line underneath (or equal to), it means we have an open circle. We also know that the line has to go to the left because all the values that go to the left make the inequality true. If they go to the right, it won't be true because the value will be greater than 21 and we need it to be less than 21.
Hope this helps :)
Answer:
C
Step-by-step explanation:
Since i can't draw the line, I will give you 2 points on the coordinate plane.
First simply the equation
y - 5 = -2/3x - 6
y = -2/3x - 1
Now pick any x
Ex: x=3 and x=0
y = -2/3 * 3 -1
y = - 2 - 1
y = -3
One point will be (3, -3)
if x=0:
y=-2/3*0 -1
y=-1
The second point will be (0, -1)
Expenses of respondents in a survey is a quantitative data and the level of measurement is a ratio scale.
<h3>What is a Qualitative and a Quantitative Data?</h3>
A quantitative data can be described as a type of data that you can measure or counted, and also given a numerical value to, while a qualitative data is a type of data that cannot be expressed using numbers.
Examples of quantitative data include, number of students in a class, weight of students in a class, etc.
Examples of qualitative data include hair color, religion, nationality, etc.
Expenses of respondents can be given numerical values, therefore, expenses of respondents in a survey is a quantitative data and the level of measurement is a ratio scale.

Answer:
166. 5
Step-by-step explanation:
Given the following :
Mean weight (m) = 142 lbs
Standard deviation (sd) = 14 lbs
Renne = 96 percentile, what is Renne's weight
Using the equation :
Zscore = (score - mean) / standard deviation
96 percentile = 0.96 is equivalent to a Zscore of
1.75
Hence,
1.75 = (score - 142) / 14
14 * 1.75 = score - 142
24.5 = score - 142
24.5 + 142 = score
Score = 166.5
