Answer 1

Answer:

a. 12

b. 1/2

Step-by-step explanation:

Given a meal has 3 choices of meat, 2 choices of fruit, and 2 choices of dessert, you want to know the number of possible meals, and the probability of a meal with no cookie for dessert.

a. Possibilities

As the tree diagram shows, the number of possible meals is ...

(possible meats)×(possible fruits)×(possible desserts)

= 3×2×2 = 12

There are 12 possible lunch options.

b. Cookies

Half the possible dessert choices have no cookie. That is the probability that a lunch will have no cookie:

P(no cookie) = 1/2

Additional comment

The bottom line of the tree diagram has 6 Cs and 6 Ms. That is, 6 of the 12 options for meals have no cookie.

Topic: Percentage

Q1) 80% of a dog's mass is equal to 24% of the mass of a lion. If the mass of the lion is 105 kg more than the mass of the dog, find the total mass of the dog and the lion.

Answers

To solve this problem, let's denote the mass of the dog as D and the mass of the lion as L.

We are given that 80% of the dog's mass is equal to 24% of the lion's mass. Mathematically, this can be expressed as:

0.80D = 0.24L

We are also given that the mass of the lion is 105 kg more than the mass of the dog:

L = D + 105

We can use these two equations to find the values of D and L.

Substituting the value of L from the second equation into the first equation:

0.80D = 0.24(D + 105)

Now, let's solve for D:

0.80D = 0.24D + 0.24(105)

0.80D - 0.24D = 25.2

0.56D = 25.2

D = 25.2 / 0.56

D ≈ 45

Now that we have the value of D, we can find the value of L by substituting it back into the second equation:

L = 45 + 105

L = 150

Therefore, the total mass of the dog and the lion is:

D + L = 45 + 150 = 195 kg

So, the total mass of the dog and the lion is 195 kg.

Based on the line plot shown below, which amount of cheese was ordered once?

C.

D.

Answers

Answer:

D; 1 and 1/2 pounds

Step-by-step explanation:

First, let's understand what the line plot is showing us. When looking, we see an amount of cheese, in pounds, with orange dots above it. Each one of these orange dots represents a person that ordered that amount of cheese. This means that 2 people ordered 1/4 pound of cheese, 4 people ordered 1/2 pound of cheese, and so on. What this means is that the amount of cheese with only one dot above it represents the amount of cheese that was ordered only once. Looking back at the line plot, the only cheese ordered once was an order for 1 and 1/2 pounds of cheese. So, our answer is D.

If this answer helped you, please leave a thanks!

Have a GREAT day!!!

Answer is D because the next to the d column there is only one dot which represents the amount of times ordered.

Discuss the case below from a governance and society perspective. In your answer list and discuss how the monkey pops outbreak in jamaica will affect the government,society and businessesJamaica has recorded its first confirmed case of monkeypox. Making the announcement during a virtual press conference on Wednesday (July 6), Minister of Health and Wellness, Dr. the Hon. Christopher Tufton, said the male patient who recently travelled from the United Kingdom is in isolation and is being treated. "He presented to the public health system on July 5, having arrived on the island some five days earlier," he said. He informed that the close contacts of the person have been quarantined following contact tracing "which will continue if necessary". Dr. Tufton said the confirmation of the first case has triggered the countrys emergency protocols, which are in line with international health regulation protocols. This, he said, includes the activation of the countrys Emergency Operations Centre. "A review of all isolation facilities is to be done to look at the capacity to manage both monkeypox and COVID-19 [coronavirus]," he said. The Minister further noted that the necessary health protocols, including surveillance, clinical management, lab management, as well as infection prevention and control, are being completed for the distribution to health teams islandwide. He added that sensitisation of the health team and members of the public, which began more than a month ago, is being enhanced. Meanwhile, Dr. Tufton said the confirmation of the virus locally is not reason for Jamaicans to panic or become fearful. "Given what has transpired globally up to this point, discovery of one case doesnt make or create a crisis. It certainly creates concerns and, indeed, we did expect, that is the health authorities, that given the presence of the monkeypox disease on the global landscape, given the openness of our country we travel a lot for business or otherwise that there was always the possibility of a case turning up here; a case or two. "Having said that, we do believe we have the capacity to respond, and particularly if Jamaicans play their part, so I do not envision the kind of response to the novel coronavirus when it came in March 2020," he said. Dr. Tufton said maintenance of the COVID-19 protocols can help to reduce transmission of the monkeypox, which is usually mild to moderate. "All members of the public should wear a mask ideally where you feel exposed normally in public, frequently wash hands and practise physical distancing, so the protocols are pretty similar to the COVID-19 virus," he said. Symptoms of the virus include fever, intense headache, swelling of the lymph nodes, back pain, muscle ache or general lack of energy or a rash. The incubation period is between five to 21 days. He said persons experiencing any of these symptoms should call ahead before visiting their medical practitioner for examination and advice. Chief Medical Officer, Dr. Jacquiline Bisasor-McKenzie said the Ministry will ramp up its communication campaign, "and of course, increasing the awareness of the clinical healthcare workers in order for them to be able to provide help to our clients, so we will be having increased awareness sessions for our healthcare providers as well," she said. She urged Jamaicans to educate themselves, so that they can increase their level of protection. Dr. Bisasor McKenzie informed that the World Health Organization (WHO) report on the virus recorded approximately 3500 cases with only one fatality. She noted, too, that Jamaica has the capacity to test for the virus through the support of the Pan-American Health Organization (PAHO). The monkeypox virus is normally found in animals, but the disease may be transmitted from animals to humans. The virus is transmitted from one person to another by close contact with lesions, body fluids, respiratory droplets and contaminated materials such as bedding.
