Step 1 : Identify the formula of calculating mean
Mean = <u>Sum of all data</u>
Number of data
Step 2 : Substitute the values in the formula
Mean = <u>10 + 15 + 25 +75 + 75 + 77 + 80 +83 + 85 + 90</u>
10
Mean = <u>615</u>
10

Answer:
The positive zero is 11
Step-by-step explanation:
Given in the question an equation,
f(x) =x² - 121
We are asked to find the positive zero of f(x)
means x > 0 for which f(x) = 0
so,
<h3> x² - 121 = 0</h3>
x² = 121
Take square root on both sides of the equation
√x² = √121
x = ±11
which means that x = 11 and x = -11
Since x > 0 so we will reject x =-11 and we will accept x = 11

a=(x1,y1)
