Answer:

if the question is what is the are of the circle without the rectangle inside it, then we could solve it easily using the Mathematical formula for A Circle's area which is

\pi {r}^{2}

since a radius is half a diameter, and the diameter is 8cm, the radius becomes 4 cm

Step-by-step explanation:

π×4^2

3.14×16

50.24

Answer:

  a) see the attached

  b) -0.1213

  c) 0.0653

  d) 0.0171

  e) EOC

Step-by-step explanation:

a) The graph shows the mean and the values at ±1, ±2, and ±3 standard deviations from the mean. Each mark differs from the one below by the value of the standard deviation, 36.18. The central mark is the mean, 704.39.

__

b) As you know, the z-score is computed from ...

  z = (x -µ)/σ

  z = (700 -704.39)/36.18

  z = -0.1213

__

c) Same formula, different numbers.

  z = (22 -21.65)/5.36

  z = 0.0653

__

d) Likewise, ...

  z = (530 -528)/117

  z = 0.0171

__

e) EOC would be the easiest. The required score has the lowest z-value, so the applicant only needs to do better than a smaller number of peers.

Actually, the answer to this depends on <em>why</em> the thresholds vary. If we assume that the threshold on each test is set appropriate to the desired knowledge and ability, the test-taker would find his knowledge and ability allows him to do better on the ACT than on the other tests.

On the other hand, if the scores are representative of test taker populations all with the same knowledge and ability, less of that knowledge is required to achieve the necessary score on the EOC.
