1)(2)(3) = 6. NOTE: Appendix E, Table 6, p. 19 contains a Table of the factorials for the integers 1 through 50. For example, 12! = 4.79002 * 108. (Or see Hayes Table 8, p. 947). Your calculator may have a factorial function labeled something like x! 2. The total number of ways of selecting r distinct combinations of N objects, Solutionfor P(3, -2, -1), Q(1, 5, 4), R(2, 0, -6), S(-4, 1, 5) find proj PS. QR Incases 1-3, the data are judged inconsistent with a population mean difference of 0. The P values are less than 0.05 and the 95% confidence intervals do not contain 0. The sample mean difference is much larger than can be explained by random variability about a population mean difference of 0.

Gravida is the # of times pregnant, para is the outcome. You usually report para (at least in your obstetrics rotation as four #s), the mneumonic being TPAL: total deliveries, premies, abortions, living children. So in short hand, a G 1 P 2 lady had twins.

More Information In fact the result holds a bit more generally, namely Lemma $\rm\ \ 24\ \ M^2 - N^2 \;$ if $\rm \; M,N \perp 6, \;$ coprime to $6.\;$ Proof $\rm\ \ \ \ \ N\perp 2 \;\Rightarrow\,\bmod 8\!\,\ N = \pm 1, \pm 3 \,\Rightarrow\, N^2\equiv 1$ $\rm\qquad\qquad N\perp 3 \;\Rightarrow\,\bmod 3\!\,\ N = \pm 1,\ $ hence $\rm\ N^2\equiv 1$ Thus $\rm\ \ 3, 8\ \ N^2 - 1 \;\Rightarrow\; 24\ \ N^2 - 1 \ $ by $\ {\rm lcm}3,8 = 24,$ by $\,\gcd3,8=1,\,$ or by CCRT. Remark $ $ It's easy to show that $\,24\,$ is the largest natural $\rm\,n\,$ such that $\rm\,n\mid a^2-1\,$ for all $\rm\,a\perp n.$ The Lemma is a special case $\rm\ n = 24\ $ of this much more general result Theorem $\ $ For naturals $\rm\ a,e,n $ with $\rm\ e,n>1 $ $\rm\quad n\ \ a^e-1$ for all $\rm a\perp n \ \iff\ \phi'p^k\\e\ $ for all $\rm\ p^k\\n,\ \ p\$ prime with $\rm \;\;\; \phi'p^k = \phip^k\ $ for odd primes $\rm p\,\ $ where $\phi$ is Euler's totient function and $\rm\ \quad \phi'2^k = 2^{k-2}\ $ if $\rm k>2\,\ $ else $\rm\,2^{k-1}$ The latter exception is due to $\rm \mathbb Z/2^k$ having multiplicative group $\,\rm C2 \times C2^{k-2}\,$ for $\,\rm k>2$. Notice that the least such exponent $\rm e$ is given by $\rm \;\lambdan\; = \;{\rm lcm}\;\{\phi'\;{p_i}^{k_i}\}\;$ where $\rm \; n = \prod {p_i}^{k_i}\;$. $\rm\lambdan$ is called the universal exponent of the group $\rm \mathbb Z/n^*,\;$ the Carmichael function. So the case at hand is simply $\rm\ \lambda24 = lcm\phi'2^3,\phi'3 = lcm2,2 = 2\.$ See here for proofs and further discussion.
