What is the equation if x=1 and y=16/3

GaryK [48]

There may be more than one way in which to answer this question. I will assume that the "equation" is a linear one: f(x) = mx + b.

Then (16/3) = m(1) + b
This is one equation in two unknowns, so it does not have a unique solution. Was there more to this problem than you have shared?

If we assume that the y-intercept (b) is zero, then y = mx, and

16/3 = 1m, so that m = 16/3, and so y = (16/3)x.

You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the

Vedmedyk [2.9K]

Answer:

416025

Step-by-step explanation:

For confidence interval of 99%, the range is (0.005, 0.995). Using a z-table, the z-score for 0.995 is 2.58.

Margin of error = 0.2% = 0.002.

Proportion is unknown. So, worse case proportion is 50%. p = 50% = 0.5.

\\ $n = \left(\frac{\texttt{z-score}}{\texttt{margin of error}} \right )^2\cdot p\cdot (1-p) \\ = \left(\frac{2.58}{0.002} \right )^2\cdot 0.5\cdot (1-0.5)=416025$

So, sample size required is 416025.

Hey there,

Your question states: You have a 332 feet fencing to enclose a rectangular region. What is the maximum area.

Your correct answer would be 6,889.

Reason/explanation:

The formula that we would use is $P = 2l+2w$

$f(x)=ax^{2} +b*x+c$

$L=166=-W\\ L=83$
_____________________________________________________________

So by this, now that we know that $L=83$

We do . . . 83 × 83. . .

And you final answer would be Option A.) 6,889

Hope this helps you!
