If the point (3,-4) is dilated by a scale factor of 74 , what are the new coordinates?
Delvig [45]

Answer:

  • (-222, 296)

Step-by-step explanation:

<u>Given point </u>

  • (3, -4)

<u>Dilation by a scale factor of 74:</u>

  • (x, y) → (74x, 74y)
  • (3, -4) → (74*3, 74(-4)) = (222, -296)

<u>Rotation by 180°:</u>

  • (x, y) → (-x, -y)
  • (222, -296) → (-222, 296)

The probability that a single radar set will detect an enemy plane is 0.9. if we have five radar sets, what is the probability t
Readme [11.4K]

The probability that a single radar set will detect an enemy plane is 0.9. if we have five radar sets, what is the probability that exactly four sets will detect the plane?

Solution: The given random experiment follows binomial distribution with p=0.9,n=5

Let x be the number of radar sets that will detect the plane.

We have to find P(x=4)

P(x=4)=\binom{5}{4}0.9^{4}(1-0.9)^{5-4}      

               =5\times 0.6561 \times 0.1

               =0.3281

Therefore, the probability that exactly four sets will detect the plane is 0.3281
