Answer:
B
Step-by-step explanation:
Part (a)
<h3>Answer:
2(2.4+w) = 14.2</h3>
--------------
Explanation:
L = 2.4 = length
W = unknown width
The perimeter of any rectangle is P = 2(L+W)
We replace L with 2.4, and replace P with 14.2 to get 14.2 = 2(2.4+w) which is equivalent to 2(2.4+w) = 14.2
========================================================
Part (b)
<h3>Answer:
w = 4.7</h3>
--------------
Explanation:
We'll solve the equation we set up in part (a)
2(2.4+w) = 14.2
2(2.4)+2(w) = 14.2
4.8+2w = 14.2
2w = 14.2-4.8
2w = 9.4
w = 9.4/2
w = 4.7
The width must be 4.7 cm.
Answer:
Correct option: e) a two-way table.
Step-by-step explanation:
In this case the store wants to see whether there is a relationship between the satisfaction level of the customer and their gender.
In statistics when there is a need to analyze or derive a relation between two categorical variables one should use a two-way table.
Categorical variables are qualitative variables that take on specific values that are usually labels. For example, grades obtained in an exam, gender, etc.
In this case the two categorical variables are: Gender and Satisfaction level.
To study the relation between the gender of a customer and their satisfaction level use a two-way table.
