Answer:
490
Step-by-step explanation:
I solved it
Solve for c by simplifying both sides of the equation then isolating the variable.
c = -32.77777777
The axis of symmetry is 2. If you look at the function <span>f(x)=(x-2)^2+3, you flip the sign of the "-2" (it would become a positive 2) that is in the parentheses and it becomes the x-coordinate of the vertex (AKA the axis of symmetry). I know it's sort of confusing, but I hope you get what I mean!</span>
Answer:
a) <em>Z-score = 0.75</em>
b) <em>Z-score = -32.833</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that mean of the Population = 33
Given a standard deviation of the Population = 12
Let 'X' be a random variable in a normal distribution
Let 'X' = 42
<u><em>Step(ii):-</em></u>
<em> </em><em></em>
<em> </em><em></em>
<u><em>Step(iii):-</em></u>
<em>Given that mean of the Population = 89</em>
Given a standard deviation of the Population = 1
Let 'X' be a random variable in a normal distribution
Let 'X⁻ = 82
<em> </em><em></em>
<em> </em><em></em>
<em>Z-score = -32.833</em>
