F(x) = x^2 . What is g(x)?

ss7ja [257]

Answer:

g(x) = (1/4x)^2

Step-by-step explanation:

Given f(x), we want to get g(x)

As we can see, the point (4,1) lies on the graph of g(x)

So the correct option will be the one where g(4) = 1

Let us take a look at the second option

g(x) = (1/4x)^2

Here,

g(4) = (1/4 * 4)^1 = 1^1 = 1

An administrator at UF wants to estimate the proportion of students who would support an increase in the student activity fee. T

Natalija [7]

Answer:

The correct answer is "664".

Step-by-step explanation:

The given values are:

Margin of error,

E = 5%

i.e.,

= 0.05

Level of confidence,

C = 99%

i.e.,

= 0.99

Level of significance,

α = 0.01

From the z value table,

Critical z = 2.576

As we know,

The required sample size n will be:

= $(\frac{z}{E} )^2\times p(1-p)$

On substituting the values, we get

= $(\frac{2.576}{0.05} )^2\times 0.5(1-0.5)$

= $(51.52)^2\times 0.25$

= $2,654.31\times 0.25$

= $663.5776$

i.e.,

= $664$

zimovet [89]

Answer:

y=4x-14

Step-by-step explanation:

m=(10-2)/(6-4)

m=8/2

m=4

y-y1=m(x-x1)

y-2=4(x-4)

y=4x-16+2

y=4x-14
