Oh My God what are you trying to talk about in this question
0.135 or in fraction is 27/20
Answer:
22+5=17
please mark as brainliest
the assumption being, that the angles at vertices C and B are right-angles, namely 90°, which will mean that C and B are points of tangency, since tangent lines and radius segments always meet at right-angles.
well, the tangents lines meet outside at a certain point, here at vertex A, when that happens, both outside tangents are the same length, so AB = 6 = AC.
<span> (a) if 1 woman is randomly selected, find the probability that her height is less than 64 in
using z-score formula:
z-score=(x-mu)/sig
(64-63.5)/2.8
=0.18
thus
P(x<64)=P(z<0.18)-=0.5714
B] </span><span> if 33 women are randomly selected, find the probability that they have a mean height less than 64 in
using the central limit theorem of sample means, we shall have:
2.8/</span>√33=0.49
since n>30 we use z-distribtuion
z(64)=(64-63.5)/0.49=1.191
The
P(x_bar<64)=P(x<1.191)=0.8830
