A polynomial is to be constructed that will touch the x axis at most 7 times. What is the minimum degree of the polynomial ?

Schach [20]

Minimum degree
ok, so
a first degree (y=mx+b) can cross at most 1 time
a 2nd degree (y=ax²+bx+c) can cross at most 2 times

so therfor we see that a nth degree polynomial can cross or touch at most n times

so 7 times means 7th degree

minimum degree is 7th degree

A confidence interval for a population mean __________. A. Estimates a likely interval for a population mean B. Estimates likeli

lisov135 [29]

Answer:

<h3>Option A) Estimates a likely interval for a population mean is correct</h3><h3>Hence a confidence interval for a population mean is used to <u>Estimates a likely interval for a population mean</u></h3>

Step-by-step explanation:

Given that a confidence interval for a population mean <u>Estimates a likely interval for a population mean</u>

For :

A confidence interval is a range of values that’s likely to include a population value with a certain degree of confidence.

It can be expressed as a the (percentage value) $\%$ where by a population mean lies between an upper and lower interval.

Therefore a confidence interval for a population mean is used to <u>Estimates a likely interval for a population mean</u>

Option A) Estimates a likely interval for a population mean is correct

<h3>Hence a confidence interval for a population mean is used to <u>Estimates a likely interval for a population mean</u></h3>

A rectangular garden covers 16,000 ft2. Its length is 60 ft longer than its width.

tatiyna

The width is x
<span>The length is x+60 </span>

<span>so x(x+60) = 16000
</span>
<span>x^2 + 60x = 16000
</span>
<span> </span>
<span>x^2 + 60x + 900 = 900+16000
</span>
<span>(x+30)^2 = 16900
</span><span> </span>
<span>x+30 = 130
</span>
<span>x = 100

So your answer is 100. </span>
