You have a coin with unknown probability p of coming up heads. You wish to generate a random variable which takes the values 0 a

elixir [45]

Answer:

(a) Hence, the probability of reporting heads is 1/2.

(b) Therefore, the expected number of such trial is 1 / 2p (1 –p).

Step-by-step explanation:

Solution:

To generate a random variable takes value 0 and 1.

Let 0 < p <1,

A coin is flipped twice.

(a) Probability of reporting head is 1/2.

The result of two toss is either HT or TH.

In this case we used conditional property, Given that you got either HT or TH,

Probability of occurring head or tail:

P (1ST = H| HT or TH]

= P (H) / P (HT or TH)

= P (HT) / P (HT or TH)

= P (1-P) / P (1-P) + (1-P)P

= P (1-P) / 2P (1-P)

=1/2

Hence, the probability of reporting heads is 1/2.

(b) Expected number of flip before report a result.

The probability of reporting a result on each trial is:

P (HT or TH)

=P (HT) + P (TH)

=P (1-P) + (1 –P) P

= 2P (1 –P)

Since, E(X) = 1 / P

Therefore, the expected number of such trial is 1 / 2p (1 –p).

Gerald mixes 2/3 cup whole wheat flour and 1/2 cup buckwheat flour to make 4 pancakes. How much of each type of flourbis needed

yulyashka [42]

Answer:

Whole Wheat = 1/6

Buckwheat = 1/8

W = whole wheat flour

B = buckwheat flour

⅔W + ½B = 4

Divide everything by 4

⅔W/4 + ½B/4 = 4/4

2/12W + 1/8B = 4/4

1/6W + ⅛B = 1

Determine the total annual fica tax for an annual salary of $38,480.

egoroff_w [7]

The annual FICA (Federal Insurance Contributions Act) tax is composed of two parts: Social Security and Medicare Taxes. On the employee's side, he/she has to shoulder 6.2% of the annual salary for the Social Security Tax, and 1.45% of the annual salary for the Medicare Tax. So in total, FICA takes 7.65% of your annual salary as tax. To calculate the FICA tax to be paid, this is shown below:

$38,480 x 7.65% = $2943.72

Therefore, for an annual salary of $38,480, $2943.72 goes into FICA tax payment.

Please explain to me and i will give brainly

GuDViN [60]

Answer:

Step-by-step explanation:

Look at any 2 adjacent numbers and find the difference between them.

Starting with numbers 1 and 2, subtract the first from the second:

$-7-(-15)=-7+15=8$

That's a difference of 8, meaning the second number increased by 8.

Check the next numbers, 2 and 3:

$1-(-7)=1+7=8$

It increased by 8 again. Now that we know for sure that each term in the sequence increases by 8 over the previous one, we can find the number in the green box. Just add 8 to the number before it:

$9+8=17$
