we are given

circumference is 2.4 miles

and we know that

C=2\pi r

so, we can find r

2.4=2\pi r

r=0.38197

now, we can find area

A=\pi r^2

we can plug values

A=\pi (0.38197)^2

Area=0.45836..............Answer

SAT scores have a mean of 1026 and a standard deviation of 209. ACT scores have a mean of 20.8 and a standard deviation of 4.8.
Y_Kistochka [10]

Answer:

The z-score for SAT exam of junior is much small than his ACT score. This means he performed well in his ACT exam and performed poor in his SAT exam.

Step-by-step explanation:

Mean SAT scores = 1026

Standard Deviation = 209

Mean ACT score = 20.8

Standard Deviation = 4.8

We are given SAT and ACT scores of a student and we have to compare them. We cannot compare them directly so we have to Normalize them i.e. convert them into such a form that we can compare the numbers in a meaningful manner. The best way out is to convert both the values into their equivalent z-scores and then do the comparison. Comparison of equivalent z-scores will tell us which score is higher and which is lower.

The formula to calculate the z-score is:

z=\frac{x-\mu}{\sigma}

Here, μ is the mean and σ is the standard deviation. x is the value we want to convert to z score.

z-score for junior scoring 860 in SAT exam will be:

z=\frac{860-1026}{209}=-7.59

z-score for junior scoring 16 in ACT exam will be:

z=\frac{16-20.8}{4.8}=-1

The z-score for SAT exam of junior is much small than his ACT score. This means he performed well in his ACT exam and performed poor in his SAT exam.

How do you divide 2\3 divided by 7\8 using kcf answer
xz_007 [3.2K]

Answer: \frac{16}{21}

<u>Step-by-Step Explanation:</u>

KCFmeans: Keep, Change, Flip

  • Keep: the first fraction
  • Change: the sign <em>from division to multiplication</em>
  • Flip: the second fraction

  \frac{2}{3} ÷ \frac{7}{8}

= \frac{2}{3} * \frac{8}{7}   <em>KCF is applied here!</em>

= \frac{2(8)}{3(7)}

= \frac{16}{21}
