Answer:
Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.
Step-by-step explanation:
3/4÷2 is equal to 3/4*1/2 so 3 times 1 is 3 and 4 times 2 is 8 so 3/4*1/2=3/8
Answer:
Every day, 43% percent of people are added from the total number of people who receive the email
Step-by-step explanation:
we know that
The equation of a exponential growth function is given by

where
P(t) is the total number of people who receive the email
t is the time in days
a is the initial value
r is the rate of change
we have

so
---> initial number of people who receive the email

solve for r

Convert to percentage

so
The daily percent change in the number of people who receive the email. every day is 43%
therefore
Every day, 43% percent of people are added from the total number of people who receive the email

<h3>How to graph a system of inequalities?</h3>
An inequality is a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following:
- Less than or equal to (≤).
- Greater than or equal to (≥).
Given the following system of inequalities:
y ≤ 1/3x ⇒ y - 1/3x ≤ 0
y - 2x < 4
By using an online graphing calculator, the solution to this system of inequalities are plotted in the image attached below.

Answer:
The original price of a skateboard is $64
Step-by-step explanation:
Let
x ----> the original price of a skateboard
y ----> the new price of a skateboard
we know that
The linear equation that represent this problem is equal to
y=x-15 ----> equation A
y=49 ---> equation B
substitute equation B in equation A and solve for x
49=x-15
Adds 15 both sides
49+15=x
64=x
Rewrite
x=$64
