Answer:
Jada: 1
Diego: 4/3
Lin: 10/3
Step-by-step explanation:
To find MAD, you calculate the mean of the data sets (which you were given in this case), and then find the distance of each number in the data set from the mean. You then write all the distances down, and then find the mean of THAT. Now you have your MAD.
Example (Jada)
Data set: 4,4,4,6,6,6
Mean: 5
Distances: 1,1,1,1,1,1
Mean of distances (and therefore the MAD):
(1+1+1+1+1+1) divided by 6 = 1
Answer:
a) The number of correct answers
b) Discrete
c) Ratio
Step-by-step explanation:
We are given the following in the question:
Experiment:
Evaluate the effectiveness of different study strategies. All students were then given a test on the passage material and the researchers recorded the number of correct answers.
a) The dependent Variable
The number of correct answers given is the dependent variable because it depends on the number of times the passage is read.
b) Nature of dependent variable.
- It is a discrete variable.
- Since, the number of questions will always be expressed in whole numbers and cannot be expressed as decimals.
- They are always counted and not measured.
c) Scale of measurement
- Ratio is used to measure the dependent variable because true zero for the number of correct questions answered exist.
- If the measure is zero that means truly no questions were answered correctly.
Answer:
Width = 54.3 inches
Step-by-step explanation:
We solve this question using the Pythagoras Theorem
Width² + Height² = Diagonal²
From the above question
Width= ??
Height = 30 inches
Diagonal = 62 inches
Width² + 30² = 62²
Width² = 62² - 30²
Width = √62² - 30²
Width =✓2944
Width = 54.258639865 inches
Approximately
Width = 54.3 inches
Hence, the new television was 54.3 inches wide.
