Given the arithmetic sequence with the following two
kondor19780726 [428]

Answer:

aₙ = -15 + 10 * (n-1)

Step-by-step explanation:

aₙ = a₁ + (n-1)*d       a₁: first term     d: common difference

a₅  a₁ + 4d =25 .... (1)

a₁₁  a₁ + 10d = 85   ...(2)

(2) - (1)     6d = 60

d = 10

a₁ = -15

Formula: aₙ = -15 + 10 * (n-1)

For one toss of a certain coin, the probability that the outcome is heads is 0.6. If this coin is tossed 5 times, which of the f
pishuonlain [190]

Answer:

The probability is 0.33696

Step-by-step explanation:

The probability that the outcome will be heads x times is calculated using the following equation:

P(x) = nCx*p^{x} *(1-p)^{n-x}

nCx is calculated as:

nCx=\frac{n!}{x!(n-x)!}

This apply for variables that follows a binomial distribution. In which we have n independent and identical events with two possibles results: success and fail with a probability p and 1-p respectively.

So, In this case, n is equal to 5, and p is equal to 0.6 because we are going to call success the event in which the outcome of the coin is head.

Then, the probability that the outcome will be heads at least 4 times is calculated as:

P = P(4) + P(5)

Where P(4) is:

P(4) = 5C4*0.6^{4} *(1-0.6)^{5-4}

P(4)=0.2592

And P(5) is:

P(5) = 5C5*0.6^{5} *(1-0.6)^{5-5}

P(4)=0.07776

Finally, the probability is:

P = 0.2592 + 0.07776

P = 0.33696

The perimeter of a triangle is 29. One side of a triangle is 5 less than twice the side of the shortest length. The third side i
PolarNik [594]

Answer:

  • 7, 9, 13

Step-by-step explanation:

Let the sides of the triangle be a, b and c.

<u>We have:</u>

  • P = a + b + c = 29
  • a = 2b - 5
  • c = b + 6

<u>Substitute values and solve for b:</u>

  • 2b - 5 + b + b + 6 = 29
  • 4b + 1 = 29
  • 4b = 28
  • b = 7

<u>Find a and c:</u>

  • a = 2*7 - 5 = 14 - 5 = 9
  • c = 7 + 6 = 13

<u>The sides are:</u> 7, 9, 13
