You are challenged to a lucky draw game. If you draw a face card (K, Q, J) from a standard deck of cards, you earn 10 points. If you draw any other card, you lose 2 points. What is the expected value that you can get if you draw another card?

Answers

To problem wants to compute the probability of the expected value that could be earn if you would draw again another card. So base on the fact that if draw a face card of K,Q,J from a standard deck correctly you will earn 10 point in just one draw, but loose 2 points if you another card, the probability that you would draw correct card in just one draw is 30.77%, so the possible value earn you have 2 points only

The equation of circle having a diameter with endpoints (-2, 1) and (6, 7) is(x - 4)² + (y - 3)² = 25
(x - 2)² + (y - 4)² = 25
(x - 2)² + (y - 4)² = 100

Answers

The center of the circle is the midpoint of the diameter.

The 'x' coordinate of the midpoint is (1/2) (6 - 2) = 2
The 'y' coordinate of the midpoint is (1/2) (7 + 1) = 4
The center of the circle is the point (2, 4) .

The length of the diameter of the circle is the distance
between the endpoints of the diameter.

The distance between (-2, 1) and (6, 7) is

√ (8² + 6²)

   = √ (64 + 36)

   = √ 100 = 10 .

The radius of the circle is 1/2 of 10 = 5 .

Now, the equation of any circle is

(x - [x of the center])² + (y - [y of the center])² = (radius)² .

and we have all the numbers now.

(x - 2)² + (y - 4)² = (5)² .

I'm very happy to see that this equation is actually
one of the choices !   I'll bet you are too.

Answer:

A number n plus 7 is less than or equal to 9

Answers

Final answer:

The subject of this question is Mathematics. The inequality n + 7 ≤ 9 can be solved by subtracting 7 from both sides. The solution is n ≤ 2.

Explanation:

The subject of this question is Mathematics. The question involves solving an inequality involving a number, n, that is added to 7 and is less than or equal to 9. To find the possible values of n, we can subtract 7 from both sides of the inequality:

n + 7 ≤ 9

n ≤ 9 - 7

n ≤ 2

So, the values of n that satisfy the inequality are any number less than or equal to 2.

Gareth has $2,000 to invest. Putting the money in a savings account at his local bank will earn him 2.2% annual interest and gives him the ability to make ATM withdrawals from that bank’s ATMs. Putting the money in an online savings account will earn him 4.85% annual interest, but he will be charged $3 every time he makes an ATM withdrawal. Assuming that Gareth’s ATM withdrawals do not affect the amount of interest he earns, roughly how many ATM withdrawals must Gareth make every year for the local savings account to be a better deal than the online savings account?
