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

An arc subtends a central angle measuring \dfrac{3\pi}{5}
Diano4ka-milaya [45]

Answer:

3/10

Step-by-step explanation:

The central angle of the arc is \frac{3 \pi}{5}.

The circumference of an arc of a circle is given as:

C_a = \frac{\theta}{2 \pi} * C

where C= circumference of the circle

θ = central angle of the arc

Therefore, the circumference of the arc is:

C_a = \frac{\frac{3 \pi}{5} }{2 \pi} * C\\\\C_a = \frac{3 \pi}{10 \pi} * C\\\\C_a = \frac{3}{10}C

The circumference of the arc will be 3/10 of the circumference of the circle.

What is the equation of the line that passes through the point (-3, 1) and has a<br> slope of - 2
Yakvenalex [24]

Step-by-step explanation:

slope = (y2-y1) / (x2-x1)

equation of the line y2 - y1 = m(x2-x1),

y2 = m(x2-x1) +y1

y2-y1 = -2(x2- (-3))

y2-y1 = -2x -6

y2 - 1 = -2x -6

y2 = -2x -5
