Answer:

x + 8 + 12 + 11 = 43

Step-by-step explanation:

The perimeter is the length of the 4 sections of fencing.

If x represents the fourth section and the perimeter is 43, then

x + 8 + 12 + 11 = 43, that is

x + 31 = 43 ( subtract 31 from both sides )

x = 12

The length of the fourth section is 12 ft

irina [24]

Answer:

Probability = 0.0073

probability = 0.000007122

Step-by-step explanation:

given data

drawing = 10 cards

ordinary -card pack = 52 pack

solution

we know that here drawings done with replacement so that there is Probability that not 2 card of the same denomination

Probability = Probability of selecting a card × Probability of selecting a card not of the first denomination × Probability of drawing a card not from 2 denominations and continuous so on .......

Probability = 1 × $\frac{52-4}{52} \times \frac{52-8}{52}$ ... .... .... .... ... ...

Probability = 0.0073

and

when cards is drawn without replacement

probability = probability that exactly 9 of same suit and 10th of a different suit + Probability all 10 are of same suit

probability = $\frac{\frac{4}{1}\times \frac{13}{9}\times \frac{52-13}{1} + \frac{4}{1} \times \frac{13}{10} }{\frac{52}{10} }$

probability = 0.000007122
