Simplify (8j3 – 10j2 – 7) – (6j3 – 10j2 – j + 12).

1 answer:

3 0

$(8j^3 - 10j^2 - 7) - (6j^3 - 10j^2 - j + 12)$

$8j^3-10j^2-7-(6j^3-10j^2-j+12)$

$8j^3-10j^2-7-6j^3-10j^2-j+12$

$(8j^3-6j^3)+(-10j^2+10j^2)+(-7-12)+j
$

$2j^3-19+j$ or $2j^3 + j - 19$

7 cards are drawn from a standard deck of 52 playing cards. How many different 7-card hands are possible if the drawing is done

Vladimir [108]

Answer:

The number of different 7 card hands possibility is 133784560

Step-by-step explanation:

The computation of the number of different 7 card hands possibility is shown below:

Here we use the combination as the orders of choosing it is not significant

So,

The number of the different hands possible would be

= $^{52}C_7$

= 52! ÷ (7! × (52 - 7)!)

= 133784560

Hence, the number of different 7 card hands possibility is 133784560

mad = 98 + 92 + 96 + 97 + 97 / 5

= 480/5

= 96

mad = (98 -96) + (92 - 96) + (96 -96) + (97- 96) + (97 -96) / 5

= 2 + (-4) + 0 + 1 + 1 / 5

=0/5

mad = 0
