The function f(x) = 2x2 + 3x + 5, when evaluated, gives a value of 19. What is the function’s input value?
Brums [2.3K]
The function's input value is 2.

f(x) = 2x² + 3x + 5
f(x) = 2(2)² + 3(2) + 5
f(x) = 2(4) + 6 + 5
f(x) = 8 + 11
f(x) = 19

Contact [7]

Answer:  a. n= 1068

b. n= 164

Step-by-step explanation:

The formula to find the sample size :

n=p(1-p)(\dfrac{z^{*}}{E})^2

, where p=prior population proportion , z* = critical z-value and E = Margin of error.

Here , let p=proportion of computers that use a new operating system.

Given : Confidence level = 95%

i.e. z* = 1.96  [by z-table]

Margin of error : E = 3% =0.03

a. If p is unknown , then we assume p=0.5

Then, n=(0.5)(1-0.5)(\dfrac{1.96}{0.03})^2=1067.11111\approx1068

i.e. n= 1068

b. p=0.96

Then, n=(0.96)(1-0.96)(\dfrac{1.96}{0.03})^2=163.908266667\approx164

i.e. n= 164.
