Answer:
1/2
Step-by-step explanation:
.5=1/2
Answer:
the relation is NOT a function
domain: {
1,-2,1}
range: {
-2, 0, 2, 3}
Step-by-step explanation:
<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
Answer:
30.5
Step-by-step explanation:
cos18=29/x --> reciprocate for simplicity : 1/cos18=x/29 --> solve for x
