If A = 8! and B = 8P8, then which one of the following is true:

meriva

Answer:

A. A = B

Step-by-step explanation:

Given

$A = 8!$

$B = ^8P_8$

Required

Which of the options is true

We start by simplifying $B = ^8P_8$

Permutation is calculated as follows

$^nP_r = \frac{n!}{(n - r)!}$

So.

$^8P_8 =\frac{8!}{(8 - 8)!}$

$^8P_8 =\frac{8!}{0!}$

0! = 1; So

$^8P_8 =\frac{8!}{1}$

$^8P_8 =8!$

Hence. B! = P!

<em>This implies that </em> $A = B = 8!$ <em />

Plot (25/3) and (42/3) on the number line.

ss7ja [257]

Answer:

Refer to the Attachment

Step-by-step explanation:

Rewriting the fractions in decimal and whole number, we have the following:

$\frac{25}{3} = 8\frac{1}{3} = 8.3$

$\frac{42}{3} = 14$

Thus, 42/3 is on 14 and 25/3 is on 8 and then add 1/3 from 8 going to 9.

Therefore, the points must be plotted as follows:

The blue point indicates the 42/3 while the red point indicates the 25/3.

Help on these 2 please!!

gladu [14]

Hope this helps
$7 \frac{1}{5} - 2 \frac{3}{5} = \frac{36}{5} - \frac{13}{5} = \frac{23}{5} = 4 \frac{3}{5}$

$8 \frac{2}{5} - 4 \frac{3}{5} = \frac{42}{5} - \frac{23}{5} = \frac{19}{5} = 3 \frac{4}{5}$
good luck
