<h3>Area of shape P = 12 square cm</h3>

Explanation:

Shape P is a triangle with the base of 4 units across the horizontal portion up top.

The height of the triangle is 6 units. Count the spaces down the middle of the triangle and you should get 6 spaces.

Area = base*height/2

Area = 4*6/2

Area = 24/2

Area = 12 square cm.

Find the indicated probability.
natka813 [3]

Answer:

C) 0.179

Step-by-step explanation:

Since the trials are independent, this is a binomial distribution:

<u>Recall:</u>

  • Binomial Distribution --> P(k)={n\choose k}p^kq^{n-k}
  • P(k) denotes the probability of k successes in n independent trials
  • p^k denotes the probability of success on each of k trials
  • q^{n-k} denotes the probability of failure on the remaining n-k trials
  • {n\choose k}=\frac{n!}{(n-k)!k!} denotes all possible ways to choose k things out of n things

<u>Given:</u>

  • n=10
  • k=4
  • p^k=0.53^4
  • q^{n-k}=(1-0.53)^{10-4}=0.47^6
  • {n\choose k}={10\choose 4}=\frac{10!}{(10-4)!4!}=210

<u>Calculate:</u>

  • P(4)=(210)(0.53^4)(0.47^6)=0.1786117069\approx0.179

Therefore, the probability that the archer will get exactly 4 bull's-eyes with 10 arrows in any order is 0.179

The side length of one of the pentagons
rosijanka [135]

Answer: 6.9 and 10.4

Step-by-step explanation:

The perimeter of the pentagon is 10 so you can either do 10 times 1.38 times 1/2 or do 5 times 1.38 and it equals 6.9

The perimeter of the hexagon is 12 and you follow the same steps so I did 6 times 1.73 and you get 10.4
