Q6 : "Social media has become a ubiquitous part of modern life, allowing people to connect with friends, family, and strangers from all around the world. However, social media use has been linked to a number of negative mental health outcomes, including increased rates of depression, anxiety, and stress. This is due in part to the constant pressure to present a perfect image of oneself, leading to feelings of inadequacy and self-doubt. Additionally, the endless stream of news and information on social media can be overwhelming and lead to feelings of information overload and burnout. However, not all social media use is negative. Research has also shown that social media can be a valuable tool for promoting social support and connection, particularly among marginalized communities. It can also be a source of education and awareness, allowing people to learn about important issues and engage with social and political causes." What is one negative mental health outcome associated with social media use?"

Higher rates of depression and anxiety are one negative mental health outcome associated with social media use
Social media and modern life:The paragraph discusses the role of social media in modern life and its impact on mental health. It notes that social media has become a ubiquitous part of life that allows people to connect with others from around the world, including friends, family, and strangers.
However, the paragraph goes on to mention that social media use has been linked to negative mental health outcomes such as depression, anxiety, and stress.
These negative outcomes may be due to the pressure individuals feel to present a perfect image of themselves online, leading to feelings of inadequacy and self-doubt.
Despite these negative outcomes, the paragraph notes that social media can also be valuable for promoting social support and connection, especially among marginalized communities.
Furthermore, it can be a source of education and awareness, allowing people to learn about important social and political issues and engage with them.

The data show your strokes for 18 holes of miniature golf.Find the mean, median, ndmode(s) of the data. Which measure best represents the data? Explain your reasoning.4, 5, 3, 3, 1, 2, 3, 2, 4, 8, 2, 4, 4, 5, 2, 3, 6, 2
We have to calculate the mean, median and mode (or modes) of the data.
The size of the sample is n = 18.
We can start by sorting the data:
[1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 6, 8]
We can calculate the mean as:
\(\begin{gathered} Mean=\frac{1}{n}\sum_{i\mathop{=}1}^nx_i \\ Mean=\frac{1}{18}(1+2*5+3*4+4*4+5*2+6+8) \\ Mean=\frac{1}{18}(1+10+12+16+10+6+8) \\ Mean=\frac{1}{18}(63) \\ Mean=3.5 \end{gathered}\)NOTE: we use the frequency of each value to save space, but we could have just add each value individually and get the same result.
We now will identify the median.
As we have an even sample size, the median will be the average between the 9th value and the 10th value.
Both values are 3, so the median is also 3.
The mode is the most frequent value in the dataset. In this case, the mode is 2, with a frequency of 5.
Both the mean and the median represent the data correctly as central measures. As the median is more robust than the mean, we can select the median as the best representation of the data.
Answer:
Mean = 3.5
Median = 3
Mode = 2
The median is a robust representation of the data.
Wyatt was out at a restaurant for dinner when the bill came. He wanted to leave a tip of 19%. What number should he multiply the cost of the meal by to find the total plus tip in one step?
Answer:
The cost of the meal should be multiplied by 1.19.---------------------------------------
Let the cost of the meal be x.
Adding a tip of 19%:
x + 19% = x + 0.19x = x (1 + 0.19) = 1.19xAnswer:
Wyatt should multiply with 1.19.
Step-by-step explanation:
Forming the expression,
→ 1 + (19% of 1)
Now the required number is,
→ 1 + (19% of 1)
→ 1 + ((19/100) × 1)
→ 1 + (19/100)
→ 1 + 0.19 = 1.19
Hence, required number is 1.19.

Find the smallest whole number by which 16087 should be multiplied or divided to get a perfect square
There is no whole number by which you can multiply or divide 16087 to make it a perfect square.
To determine by which number you should multiply or divide 16087 to make it a perfect square, we can analyze its prime factorization. The prime factorization of 16087 is 13 × 1237.
In order to make 16087 a perfect square, we need each prime factor to have an even exponent. However, when we examine the prime factors of 16087, we find that both 13 and 1237 have an exponent of 1.
To make the exponents even, we need to multiply or divide 16087 by additional prime factors and their respective exponents. However, since 16087 is a product of two prime numbers (13 and 1237), we cannot introduce any additional prime factors to make the exponents even.
A perfect square is a number that can be expressed as the product of two equal factors. In the case of 16087, it cannot be transformed into a perfect square by multiplying or dividing by any whole number. The prime factors 13 and 1237 remain with an exponent of 1 each, indicating that there is no integer that can be applied to make them equal and convert 16087 into a perfect square.
Therefore, there is no whole number by which you can multiply or divide 16087 to make it a perfect square.

My own multi-step combination problem is given below:
Amanda was planning a dinner party for 10 people, and she want to choose a menu of 3 fruit , 2 meat pie, and 2 desserts. Amanda have a total of 5 fruit , 4 meat pie, and 3 desserts to choose from. How many different dinner menus can Amanda create?How do you solve the multi-step combination?To solve this problem, Amanda need to use the formula for combinations and it is:
nCr = n! / (r! x (n-r)!)
where:
n = total number of items to select from
r is the number of items to select.
First, we have to calculate the number of ways to select 3 fruit from 5, hence it will be:
5C3
= 5! / (3! x (5-3)!)
= 10
Next, we have to calculate the number of ways to select 2 meatpie from 4 and it will be
4C2
= 4! / (2! x (4-2)!)
= 6
Lastly,, we need to calculate the number of ways to select 2 desserts from 3 and it will be:
3C2
= 3! / (2! x (3-2)!)
= 3
To have the total number of dinner menus, we have to multiply these three numbers together:
= 10 x 6 x 3
= 180
Therefore, one can say that Amanda have 180 different dinner menus that she can be create.

Roll a pair of fair six-sided dice. Let D denote the absolute value of the difference between the dice. For example, if a 3 and a 5 are rolled, then D = 2. Find the expected value of the random vari- able D, E[D]. 1. E[D]= 2. E[D]= 3. E[D] = 4. E[D]= 76 36 36 70 36 72 36
The expected value of the random variable D is 6.. This gives us the following equation :E[D] = 0(1/6) + 1(1/6) + 2(1/6) + 3(1/6) + 4(1/6) + 5(1/6)
The expected value of the random variable D, E[D], can be calculated using the following formula :E[D] = ΣD P(D) Where ΣD is the sum of all possible values of D and P(D) is the probability of each of those values. In this case, the possible values of D are 0, 1, 2, 3, 4, 5. The probability of each of these values is the same, since each has an equal chance of being rolled on the dice. To calculate the expected value, we must multiply each value of D with its probability, and then sum all of these products. This gives us the following equation:E[D] = 0(1/6) + 1(1/6) + 2(1/6) + 3(1/6) + 4(1/6) + 5(1/6) .E[D] = 36/6 = 6.Therefore, the expected value of the random variable D is 6.
