Apply the formula of n!/{(r!)(n-r)!}


Where n= 9
And r= 5

9!/{(5!)(9-5)!}
= 9!/{(5!)(4)!}
= ( 9×8×7×6×5×4×3×2×1)/(5×4×3×2×1) (4×3×2×1)
= 126.

So, option d is correct.

A quics way to do this :-

9C5    = 9*8*7*6*5              3 * 7 * 6   =    126
             -------------        =     
              5*4*3*2*1

In this problem we need to find the value of a and b. So given that t<span>he function should be in the form f(n) = an + b and we know each value of n, then out goal is to find a and b.

For getting this purpose, we need to find a system of two equations (given that we have two unknown variables)

Therefore:

(1) f(0) = a(1) + b = 18
</span>∴ a + b = 18
<span>
(2) f(1) = a(2) + b = 24
</span>∴ 2a + b = 24<span>

Solving for a and b we have:

a = 6
b = 12

Finally:

f(n) = 6n + 12</span>

What is the best example of elasticity demand in the context university of rwanda
WINSTONCH [101]

Answer:

Step-by-step explanation:

<u>Elasticity Demand</u>

  • The flexibility of interest is a significant minor departure from the idea of interest. Request can be delegated as versatile, inelastic, or unitary.
  • Flexible interest is one in which the adjustment of the amount requested because of an adjustment of cost is huge. An inelastic interest is one in which the adjustment of the amount requested because of an adjustment of cost is little.
  • The equation for processing versatility of interest is:

(Q1 - Q2)/(Q1 + Q2)

(P1 - P2)/(P1 + P2)

  • In the event that the recipe makes an outright worth more prominent than 1, the interest is flexible. At the end of the day, the amount changes quicker than the cost. On the off chance that the worth is under 1, the request is inelastic. All in all, the amount changes more slowly than the cost. In the event that the number is equivalent to 1, the flexibility of interest is unitary. All in all, the amount changes at a similar rate as the cost.
  • An illustration of items with a flexible interest is purchaser durables. These are things that are bought inconsistently, similar to a clothes washer or an auto, and can be deferred assuming the cost rises. For instance, vehicle refunds have been extremely fruitful in expanding car deals by diminishing costs.
