If f(x) = x^2

Then g(x) goes under the 3 transformations given...,

; Reflection on the x-axis...; -f(x)

; 3 units to the left...., -f(x + 3)

; 7 units up..., -f(x + 3) + 7

Then for....,g(x) = -f(x + 3) + 7

Where the function is going to be...

; g(x) = -(x + 3)^2 + 7

; g(x) = -(x^2 + 6x + 9) + 7

; g(x) = -x^2 - 6x - 9 + 7

;Hence the function of g(x) after all those transformations

g(x) = -x^2 - 6x - 2

How many whale sharks would a researcher need to measure so that 90% confidence level would have a margin of error of 0.25
Vika [28.1K]

About 1407 sharks would be needed to have a margin of error of 0.25

<h3>What is margin of error?</h3>

Margin of error is used to determine by what value there is deviation from the real value. Margin of error (E) is given by:

E=Z_\frac{\alpha}{2} *\frac{standard\ deviation}{\sqrt{sample\ size} }

The 90% confidence level have a z score of 1.645. Hence for E = 0.25, standard deviation = 5.7 feet, hence:

0.25=1.645*\frac{5.7}{\sqrt{sample\ size}}\\ \\sample\ size=1407

About 1407 sharks would be needed to have a margin of error of 0.25
