A) Variance = 10.24
B) Standard Deviation = 3.2
One of the measurements of dispersion is the standard deviation, which is exclusively used for quantitative data. It aids in determining if the data's mean is a suitable measurement to reflect the core value.

Standard Deviation = 
√4.35 - √1.15
Standard Deviation = 3.2
(SD)² = (3.2)² = 10.24
Variance = 10.24

Answer:
An equation that indicates you can spend exactly $45 per day for rental fees is, 
Step-by-step explanation:
Let x represents the days and y represents total the rental fees.
As per the statement:
you can spend exactly $45 per day for rental fees.
In 1 day you spend = $45 rental fees.
then
in x days = 45 x
we have to find an equation that indicates you can spend exactly $45 per day for rental fees
since, y represents the total rental fees,.
⇒ y= 45x
Therefore, an equation that indicates you can spend exactly $45 per day for rental fees is,
