Correlation coeffiencients is used to determine the relationships between data, Correlation coefficients can test two or more variable(s) at a time

<h3 /><h3>What are correlation coefficients?</h3>

This is a linear correlation between sets of data. This coefficient can only be between -1 and 1.

Positive values show a positive correlation while a negative value shows negative correlation.  A correlation coefficient of zero shows no relationship between variables.

Based on the explanation, we can conclude that Correlation coefficients can test two or more variable(s) at a time

Shelley wants to purchase a cell phone package, which includes a free phone. The cost of the package is $0.10 per minute, for th
GarryVolchara [31]

Answer:

The function would be linear because the rate of change is constant.

Step-by-step explanation:

Given

Base= \$89.00

Rate = \$0.10 per minute

See attachment for complete question and options

First, we write the function that calculates the cost (C(t)) for t minutes.

This is calculated as:

Cost = Base + Rate * t

C(t) = 89.00 + 0.10 * t

C(t) = 89.00 + 0.10t

Rewrite as:

C(t) = 0.10t + 89.00

A function that has the above format is referred to as a linear function which has the general format

f(x) = mx + b

Where

m represents the slope/rate and it is constant

From the list of given options, (a) is correct.
