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

which of the following situations describe exponential growth? check all of the boxes that apply. the number of butterflies in an area increases by 10% per year. the population of a city increases by 500 people per year. kristy bought a collector’s coin for $2.15 and its value increases at a rate of 3% per year. the number of people who have heard a rumor increases because every person tells 2 other people.

Answers

The situations that describe exponential growth are;

1 ; The number of butterflies in an area increases by 10% per year.

3; Kristy bought a collector’s coin for $2.15 and its value increases at a rate of 3% per year.

4; The number of people who have heard a rumor increases because every person tells 2 other people.

Exponential growth generally can be represented by the formula;

f(n) = a(1 + r)ⁿ

where;

f(n) = exponential growth function

a = initial amount

r = growth rate in %

n = number of time intervals

1) The growth rate of the butterflies increase by 10% every year;

This can be modelled by an exponential growth function because we are given growth rate.

2) The population of a city increases by 500 people per year; This can't be modelled by exponential growth function because the growth rate is not in percentage.

3) Kristy bought a collector’s coin for $2.15 and its value increases at a rate of 3% per year;This can be modelled by an exponential growth function because we are given growth rate in %.

4) The number of people who have heard a rumor increases because every person tells 2 other people; This can be modelled by an exponential growth pattern because the rate of increase is 2 for every one person which is exponential in nature.

Answers

Sulfur valence electrons have an effective nuclear charge of +6.

What are effective nuclear charge?

Effective nuclear charge is defined as the true positive nuclear charge that an electron in a multi-electron atom experiences. Electrons and protons are the two elements that cause the effective nuclear charge to rise. Zeff = Z - S is the actual nuclear charge.

A sulfur second row electron's effective nuclear charge is 14. Since sulfur contains 16 protons, or 16 atomic numbers, we know that there are 2 electrons in its first shell or orbit, which due to its rapid speed creates a shielding effect.

Thus, sulfur valence electrons have an effective nuclear charge of +6.

in the late 1800s, china experienced an internal crisis when emperor guang xu launched massive reforms throughout the nation. why were these reforms opposed, thus creating an internal crisis in china?

Answers

Note that in the late 1800s, China experienced an internal crisis when emperor Guang Xu launched massive reforms throughout the nation. It is to be noted that these reforms were opposed and hence caused internal crises because: "Some people felt reforms would ruin the Chinese economy." (Option A)

How did the crises erupt?

Among many persons, Prince Duan, a late Qing dynasty stateman, was the most vocal in his opposition to the changes. Prince Duan had resisted the changes because he felt a foreign scheme was at work, with many Western concepts, including military tactics, education, and political methods, being proposed for implementation, and he was threatening to deport all foreigners from China.

As a result, they executed and imprisoned all reform supporters and held King Guang Xu under house arrest until his death.

How does the simplest bacteria relate to the most complex animal.

Answers

Answer:

the simplest bacteria relate to the most complex animal because organisms share the same DNA bases.

Explanation:

Deoxyribonucleic acid (DNA) is a double helix molecule that contains the genetic material of all organisms by which their cells can synthesize proteins.

The genetic material (DNA) passes across generations from parents to offspring to be used by cells to carry out all metabolic functions (e.g., growth, reproduction, differentiation, etc)

• In DNA, there are the same four types of nucleotides in all types of cells, each one containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine and Thymine).

The simplest bacteria relate to the most complex animal, as all organisms share common DNA bases. The correct option is B.

What are DNA bases?

All creatures have a double-helix molecule called deoxyribonucleic acid (DNA), which serves as their genetic blueprint and allows their cells to produce proteins. Four bases are found in both DNA and RNA, and they are connected by hydrogen bonds.

While DNA has timing and RNA has uracil in place of thymine, all other bases are the same. The base pairs are compatible with one another. Cells require the genetic material (DNA) passed down from parents to children to perform all metabolic processes (e.g., growth, reproduction, differentiation, etc).

All types of cells have the same four types of nucleotides in their DNA, each of which has a unique nitrogenous base (i.e., Adenine, Guanine, Cytosine and Thymine).

Therefore, the correct option is B. all organisms share common DNA bases.

Marian traveled at an average speed of 65 mi/h for 15 hours. Kristen travels at an average speed of 50 mi/h. How many hours does it take kristen to travel the same distance marian traveled? express your answer as a decimal to the nearest tenth.

Answers

The hours it takes Kristen to travel the same distance Marian travelled is 19.5 hours.

The average speed of Marian is 65 miles per hour for 15 hours. Therefore, her distance travelled can be calculated as follows:

speed = distance / time

Therefore,

distance = time × speed

distance = 15 × 65

distance = 975 miles

Kristen travelled at an average speed of 50 miles per hour. Kristen covers the same distance with Marian. Therefore, the hours it takes Kristen to travel the same distance Marian travelled can be calculated as follows:
