it is 2(x-4)+3x=22 2(6-4)+3(6)
The range, the mean, and standard deviation are mathematically given as
Participants ranged in age from 4 to 26.24 ( M = 26.24 , SD = 8.04 ). Option D.
<h3>What are the
range, the
mean, and
standard deviation?</h3>
Given the data presented below the given
A look at the result shows that the lowest and highest values are between 1s and 58, with a mean and standard deviation of 26.10 and 8.90, respectively.
Participants' ages varied from 18 to 58 (m-26.14, std dev = 8.01), hence option (d) is accurate.

Andre is 3.8 miles away from his house.
<h3>What is mathematical expression?</h3>
Expression or mathematical expression serves as the combination of symbols which is been formed base on rules that depend on the context.
First trail he hiked took him 4 1/2 miles = 4.5 miles
Second trail he hiked took him 2 4/10 closer to his house= -2.4
Third trail he hiked took him 1 7/10 miles further away from his house =1.7
we can write the expression as (4.5 - 2.4 + 1.7)
= 3.8
Therefore, Andre is 3.8 miles away from his house.
