Answer:

Step-by-step explanation:

Since you are only going out 4 terms, you could just list the terms and add.

5*(-2/3)^0 = 5 * 1 = 5

5*(-2/3)^1 = 5 *(-2/3) = -10/3

5*( - 2/3)^2 = 5*(-2/3)^2 = 5*(4/9) = 20/9

5*(-2/3)^3 = 5*(-2/3)^3= 5 *(-8/27) = -40/27

Answer

5 - 10/3 + 20/9 - 40/27

5 - 90/27 + 60/27 - 40/27

5 - 70/27

2 11/27

The probability that a male professional golfer makes a hole-in-one is 1/2780. Suppose 36 professional male golfers play the six
yuradex [85]

Answer:

The right solution  is "9.7\times 10^{-10}".

Step-by-step explanation:

According to the question,

The probability that male professional golfer makes hole in one will be:

P=\frac{1}{2780}

Number of players,

n = 36

and,

q=1-P=\frac{2779}{2780}

By using the Binomial theorem, we get

⇒ P(x=r) = \binom{n}{r} p^r q^{n-r}

Bu substituting the values, we get

                   =\binom{36}{4} (\frac{1}{2780} )^4 (\frac{2779}{2780} )^{32}

                   =9.74929\times 10^{-10}

or,

                   =9.7\times 10^{-10}

Jaime knows that 30² is 900. He wonders if knowing that 30² can help him finds 29x31. Raquel knows what 25² equals. How can she
iragen [17]

Answer:

  Jaime: yes: 29·31 = 900 -1 = 899

  Raquel: 24·26 = 25^2 -1 = 624

Step-by-step explanation:

The difference of squares factors as the product of the sum and difference of the roots:

  a^2 -b^2 = (a -b)(a +b)

<u>Jaime</u>

  29·31 = (30 -1)(30 +1) = 30^2 -1^2 = 900 -1 = 899

  Jaime can subtract 1 from 30^2 to find 29·31

__

<u>Raquel</u>

  24·26 = (25 -1)(25 +1) = 25^2 -1^2 = 625 -1 = 624

  Raquel can subtract 1^2 from 25^2 to find 24·26.

The keyword is "sum" which tells you x, y, and z are being added. One half of the sum means that the sum of the three numbers is going to be divided by 2.

x + y + z
