Answer: I believe 0,-2
Step-by-step explanation:
<span>The parent cosine function can be transformed and translated. So, from the basic function cos(x) we can obtain function acos(bx+c). In our case, a=3- amplitude, b=10- the period change and c=-pi- the phase shift. So, the parent cosine function is mutiplied with 3 (which gives the amplitude of the function, 3*0.5=1.5). The period of the function is changed, and is 2pi/b=2pi/10=pi/5 and the cos(x) is phase shifted for c/b=-pi/10.</span>
Z score = n - mu / d where mu = mean and d = std dev.
for n = 14 we hav ez score of (14-20) / 2.8 = -2.143
unusual as he is in the bottom 5%
