Answer:
Given that the maximum age of the textbook is 7.9 years and the minimum age of the textbook is 1.3 years.
Using the range rule, the standard deviation is estimated as,
S≈maximum−minimum/4
=7.9−1.3/4
=1.65
The required value of the approximate standard deviation is 1.65.
Answer:
5x(squared)-4x+1
2x(squared)+11xy+14
7x(squared)+7xy+3x-17
Step-by-step explanation:
An equation is formed of two equal expressions. The solution of the equation is 41.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution of the equation,
x + 21 = 62
x = 62 - 21
x = 41
Hence, the solution of the equation is 41.

250/360 = x/60
x = 41.7 cm
This is because when the whole circle is 250 cm (angle is 360 degrees), 60 degrees means that the arc is 41.7 cm.
