Answer:
q= (23+8a)/a
Step-by-step explanation:
a(q-8)=23
or, aq-8a = 23
or, aq = 23+8a
or, q = (23+8a)/a
Count the squares
6 x 3.5
Area = 6 x 3.5
Area = 21
Perimeter = 6 + 6 + 3.5 + 3.5
Perimeter = 19
The standard deviation of the sampled containers contents is 0.50.
Option (b) is correct.
To find the standard deviation.
<h3>What is a standard deviation?</h3>
A standard deviation (or σ) exists as a measure of how dispersed the data exists about the mean. Low standard deviation means data exist clustered about the mean, and high standard deviation suggests data exist better extended out.
Given that:
Mean is the sum of all values divided by the total number of values.
Mean
= (1/10) [19.52+19.61+19.62+20.3+19.74+19.88+19.9+19.8+20.97+20.92]
= 200.26/10
= 20.02
s^2=1/10[(19.52-20.02)^2+(19.61-20.02)^2+(19.62-20.02)^2+(20.3-20.02)^2+(19.74-20.02)^2+(19.88-20.02)^2+(19.9-20.02)^2+(19.8-20.02)^2+(20.97-20.02)^2+(20.92-20.02)^2]
1/10*2.52
=0.25
s=0.50
The standard deviation exists at 0.50293.
Therefore, the standard deviation of the sampled containers contents is 0.50.
