Is the exact time it takes to evaluate 27 plus 72exact time it takes to evaluate 27+72 discrete or continuous?

Time is continuous.

If it was possible to measure EXACTLY the time it takes a person (or group of people) to evaluate 27 + 72 (=99), the time(s) people took could be 2 seconds, 3 seconds, 2.5 seconds, 2.25 seconds, 2.22 seconds, 2.2199999 seconds... In other words, any value is possible when measuring "exact" time elapsed.

However, people are limited by the tools they use. There isn't a tool without limits in its ability to measure time elapsed. For example, is the stopwatch accurate to 1/100th of a second? 1/1000th of a second? At some point it reaches its limit. The constraints of the tool being used to measure are going to, in fact, cause data to be "discrete."

I'm 90% sure you're teacher is looking for "continuous" as the solution though. So don't bring up "discrete" unless you feel like you'll be able to confidently explain the second paragraph above.

Answer:

/65

Step-by-step explanation:

a²+b²=c²

c will always be the hypotenuse

4²+7²=65² the opposite of ² is square root so

/65

it doesn't want it answered so that's your final answer.

Write the equation of a circle with center (4, -5) and radius = square root of 13

Anon25 [30]

<h2>Hello!</h2>

The answer is:

The equation of the given circle is:

$(x-4)^{2}+(y+5)^{2}=13$

The equation of a circle is given by the following equation:

$(x-h)^{2} +(y-k)^{2}=r^{2}$

We are given the center point (4,-5) and the radius.

So,

Where:

$h=x=4\\k=y=-5\\r=\sqrt{13}$

Then, substituting into the circle equation, we have:

$(x-4)^{2} +(y-(-5))^{2}=(\sqrt{13})^{2}$

Hence, the simplified equation of the circle is:

$(x-4)^{2}+(y+5)^{2}=13$

Have a nice day!

in 2013 January there were 360 pupils in school the ratio of boots to girls was 5:4 in February 18 boys were admitted in school

anyanavicka [17]

Answer:

218

Step-by-step explanation:

this is ratio.

5+4=9. which is the ratio you add it.

5/9×360=200

therefore the number of boys in school during 2013 january is 200 plus admitted boys in February is 200+18=218.

therefore the number of boys in school from january to february is 218.

You wish to test the following claim ( H a ) at a significance level of α = 0.01 . H o : μ = 60.8 H a : μ ≠ 60.8 You believe the

ad-work [718]

Answer:

Step-by-step explanation:

This is a test of a single population mean since we are dealing with mean

For the null hypothesis,

µ = 60.8

For the alternative hypothesis,

µ ≠ 60.8

Since the number of samples is small and no population standard deviation is given, the distribution is a student's t.

Since n = 8,

Degrees of freedom, df = n - 1 = 8 - 1 = 7

t = (x - µ)/(s/√n)

Where

x = sample mean = 66.9

µ = population mean = 60.8

s = samples standard deviation = 10.7

t = (66.9 - 60.8)/(10.7/√8) = 1.61

We would determine the p value using the t test calculator. It becomes

p = 0.076

Since alpha, 0.01 < than the p value, 0.076, then we would fail to reject the null hypothesis. Therefore, At a 1 % level of significance, the sample data showed that there is no significant evidence that μ ≠ 60.8

Therefore, this p-value leads to a decision to accept the null hypothesis
