Answer:

1

Step-by-step explanation:

I am assuming the question is asking which x value plugged into the function will give you a zero so

(-1)3 -8(-1)2 -23(-1)+30

so that simplyfiys to -1-8(1)+23+30

so that is -1-8+53

so -9+53

= 44

trying 3 we get

(3)3-8(3)2-23(3)+30

so that is 27 -72-69+30

and that is not zero

trying -10

we get

(-10)3-8(-10)2-23(-10)+30

which is -1000- 800+230+30

that is not zero so lastly trying  1 we get

(1)3-8(1)2-23(1)+30

which is 1-8-23+30

which is -7+7 which is zero

Abiodun and taiwo share 735 naira between them so that abiodun get 95naira more than taiwo find how much money each gets
DerKrebs [107]

Answer:

Abiodun gets - <u>415 naira</u>

Taiwo gets -<u> 320 naira</u>

Step-by-step explanation:

Let us consider  x and y as Abiodun and Taiwo,

Therefore , acccording to the question , equation formed will be -

 x+y=735 naira ------ 1

and

x=y+95

x-y=95 ------2

From equation 1 and 2, we get

   2x=830

x=\frac{830}{2}

x=415 naira (that is Abiodun share)

now , Calculating Taiwo share from equation 1

x+y=735\\415+y=735

y=735-415

y = 320 naira (that is Taiwo share )

Therefore , Share of Abiodun = 415 naira

   Share of Taiwo = 320 naira

The expected values of the binomial distribution are given as follows:

1. 214.

2. 21.

3. 31.

<h3>What is the binomial probability distribution?</h3>

It is the <u>probability of exactly x successes on n repeated trials, with p probability</u> of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

For item 1, the parameters are:

p = 3/7, n = 500.

Hence the expected value is:

E(X) = np = 500 x 3/7 = 1500/7 = 214.

For item 2, the parameters are:

p = 0.083, n = 250.

Hence the expected value is:

E(X) = np = 250 x 0.083 = 21.

For item 3, the parameters are:

p = 1/13, n = 400.

Hence the expected value is:

E(X) = np = 400 x 1/13 = 31.
