A player pays $15 to play a game in which a chip is randomly selected from a bag of chips. The bag contains 10 red chips, 4 blue chips, and 6 yellow chips. The player wins $5 if a red chip is selected, $10 if a blue chip is selected, and $20 if a yellow chip is selected. Let the random variable x represent the amount won from the selection of the chip, and let the random variable w represent the total amount won, where w=x−15. What is the mean of w ? $10. 50 answer a: $10. 50 a $4. 50 answer b: $4. 50 b −$4. 50 answer c: negative 4. 50 dollars c −$6. 50 answer d: negative 6. 50 dollars d −$10. 50.

Answers

Answer 1

The mean of the random variable w that represents the total amount won is; -$4.50

We are given quantity of chips inside the bag as;

Number of red chips = 10Number of blue chips = 4Number of Yellow chips = 6

Total number of chips = 20

Thus;

P(Red chips) = 10/20 = 0.5P(blue chips) 4/20 = 0.2P(Yellow Chips) = 6/20 = 0.3

Amount won from the selection of Red Chip = 0.5 * $5 = $2.5

Amount won from the selection blue Chip = 0.2 * $10 = $2

Amount won from selection of yellow chip = 0.3 * $20 = $6

Thus;

x = $2.5 + $2 + $6

x = $10.5

We are told that total amount won is gotten from;

w = x − 15

Thus;

w = 10.5 - 15

w = -$4.50

Answers

Answer: option b it produces a contradictory urge to stop reading and to continue

Explanation:

Hope this helps

The correct response is - Option B results in a conflicting impulse to quit reading and to continue, which is the B answer.

What is an Impulse?

In classical mechanics, the integral of both a force, F, over the time period over which it acts, t, is referred to as the "impulse." Impulse is a vector quantity since force is one as well. When an item receives an impulse, its linear momentum likewise changes in the opposite direction in an analogous vector.

The impulse function is a very brief pulse that can theoretically never end that is used to assess system dynamics. An impulse function in the real world is a pulse that is substantially shorter than the system's temporal response.

In physics, the term "impulse" is used to characterize or measure the impact of force operating gradually to alter an object's motion. The letter J stands for it, and is typically expressed in Newton-seconds

Emma puts $10,000 in a simple interest account at a bank. She will earn $1,800 in 4 years. What is the annual interest rate for the account?.

Answers

Answer: 4.5%

Explanation:

A = P(1 + rt)

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

A = 10000 + 1800 = 11800

11800 = 10000 (1 + r4)

1.18 = 1 + 4r

4r = 0.18

r = 0.18/4 = 0.045 = 4.5%

The required annual interest rate is  4.5% for the account.

What is the simple interest?

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100.

A = P(1 + rt) ...(i)

First, we have to find the final amount

Initial principal amount (P) =  $10,000

Time (t in years) = 4

A = P + S.I.

A = 10000 + 1800 = 11800

Substitute the values in the above formula (i),

11800 = 10000 (1 + r × 4)

1.18 = 1 + 4r

4r = 0.18

r = 0.18/4 = 0.045 = 4.5%

Therefore, the required annual interest rate is  4.5% for the account.

Answers

Answer:

Given

Rate of interest = 10% per annum

Principal for the first year = Rs 6000

Interest for the first year = Rs (6000 × 10 × 1) / 100

= Rs 600

Amount at the end of first year = Rs 6000 + Rs 600

= Rs 6600

Principal for the second year = Rs 6600

Interest for the second year = Rs (6600 × 10 × 1) / 100

= Rs 660

Amount for the second year = Rs 6600 + Rs 660

= Rs 7260

Therefore, compound interest for 2 years = final amount – (original) Principal

= Rs 7260 – Rs 6000

We get,

= Rs 1260

Answers

Since the boulder is raised with constant velocity, the net force on the boulder is zero, so that the boulder has weight 175 N on this planet. If its mass is 87.5 kg, then the acceleration due to gravity is g such that

175 N = (87.5 kg) g   ⇒   g = (175 N) / (87.5 kg) = 2.00 N/kg = 2.00 m/s²
