Answer 1

Answer:

Range = 205 dollars

Variance = 3255.9 square dollars

Standard deviation = 57.06 dollars

Explanation:

Range = highest price - lowest price = 280 - 75 = 205 dollars

Mean = summation of prices ÷ number of hotels = (186+213+75+188+158+280+197) ÷ 7 = 1297 ÷ 7 = 185.3 dollars

Variance = (summation of square of the difference between each price and mean) ÷ number of hotels = [(186-185.3)^2 + (213-185.3)^2 + (75-185.3)^2 + (188-185.3)^2 + (158-185.3)^2 + (280-185.3)^2 + (197-185.3)^2] ÷ 7 = 22791.43 ÷ 7 = 3255.9 square dollars

Standard deviation = sqrt(variance) = sqrt(3255.9 square dollars) = 57.06 dollars

What is the probability that a child can Will randomly choose a meal with a cheeseburger and cookie

Answers

Final answer:

The probability that a child chooses a meal with a cheeseburger and cookie is 1/12 or approximately 0.0833.

Explanation:

To find the probability that a child randomly chooses a meal with a cheeseburger and cookie, we need to determine the total number of possible meals and the number of meals that have a cheeseburger and cookie.

Let's say there are 3 drink options, 4 entree options, and 2 dessert options.

The total number of possible meals is 3 * 4 * 2 = 24.

Out of these 24 meals, let's say there are 2 meals that have a cheeseburger and a cookie.

Therefore, the probability that a child randomly chooses a meal with a cheeseburger and cookie is 2/24 = 1/12 or approximately 0.0833.

Answers

B. a chart showing the foods people should eat everyday

If you were to try and eat healthy you should see what you should eat to be healthy.

b- a chart showing the foods people most like to eat. showing the most liked foods is useless bc most foods generally favored by the population aren’t the healthiest. showing different foods at different meals and showing foods in other countries are both irrelevant answers bc that has nothing to do with healthy food choices

Explain two religious beliefs about adultery (include and
explain teachings).(4 marks)​

Answers

Answer:

Christians believe that this commandment (it's one of the 10 commandments, "thou shalt not covet another man's wife") shows that God wants people to exercise sexual fidelity within marriage and chastity before marriage. Adultery means having sex with someone to whom you are not married. Christianity teaches that adultery is wrong and sinful. In many sects, divorce and remarriage is considered adultery. In fact, even having impure thoughts is adultery. In the Bible, Leviticus 20:10 subsequently prescribes capital punishment for adultery, but refers to adultery between a man and a married woman: And the man that commits adultery with another man's wife, even he that commit adultery with his neighbour's wife, the adulterer and the adulteress shall surely be put to death. In the New Testament, you can be forgiven if you repent of your sins and ask Jesus to forgive you, covering you with his perfect blood.

Hinduism:  Adultery is a consensual physical correlation between two individuals who are not married to each other. According to Hinduism dictionary,” Adultery is sexual intercourse between a married man and a woman not his wife, or between a married woman and a man not her husband.” In Hindu shastras, adultery is considered as a serious breach of dharma. Hinduism considers marriage as a sacred and a highly sanctified relationship.
