Katarina [22]3 years ago

If you're going to write negative exponents, please enclose them inside parentheses:

12 / c^(-8)
                                       12      8d^2
<span>12/c^-8d^2 becomes  --------- - ---------
                                       c^8        1

Here the LCD is c^8, so the above expression becomes:

 12         c^8*d^2       12-(c^8)(d^2)
------- - ------------- = ---------------------
 c^8          c^8                   c^8</span>

When simplifying rational numbers, what would the answer be to 57/69
Irina-Kira [14]
You don't simplify rational numbers, but sometimes you can simplify a fraction.
The way to do that is to divide the top and bottom by their greatest common factor.

The greatest common factor of 57 and 69 is 3 .  When you divide the top and
bottom by 3 , you have  19/23 .  That's the simplest form of that particular fraction.

Assume that women's heights are normally distributed with a mean given by , and a standard deviation given by . μ = 63.5 in σ =
tresset_1 [31]
<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
