Answers

Answer 1

Answer: If you would like to find the number, you can calculate this using the following steps:

n = ? ... a number

the difference of six times a number and 7 is -49
6 * n - 7 = - 49
6 * n = - 49 + 7
6 * n = - 42
n = - 42 / 6
n = - 7

The correct result would be - 7.

I hope this helps you

-x+6y=5

Standard form is Ax+By=C, so with that knowledge, we can work with the problem to get it how we want it!

Our first step is to get x and y on the same side of the equals sign. To do that, we can subtract an x from both sides, turning 6y = x + 5 into -x +6y = 5. Lucky for us, this brings us straight to the answer, which is A) -x +6y = 5!

System of equations - urgent please help ben is making a new Twitter account and has 72 followers on his first day. He averages 10 new followers each week after that. Sarah also started a Twitter account and has 100 followers on her first day and averages 3 new followers each week. After how many weeks will they have the same number of followers?

Answers

Answer:

4 weeks

Step-by-step explanation:

Step one:

ben has 72 followers on his first day.

He averages 10 new followers each week

let the number of weeks be x

and the total followers be y

y= 72+10x--------1

Sarah also started a Twitter account and

has 100 followers on her first day and averages

3 new followers each week

let the number of weeks be x

and the total followers be y

y= 100+3x--------2

Step two:

let us equate the two expression to get the number of weeks x

72+10x=100+3x

collect like terms

10x-3x=100-72

7x=28

divide both sides by 7

x=28/7

x= 4 weeks

Legalization of marijuana, Part 1. The 2010 General Social Survey asked 1,259 US res- idents: "Do you think the use of marijuana should be made legal, or not?" 48% of the respondents said it should be made legal. (a) Is 48% a sample statistic or a population parameter? Explain. (b) Construct a 95% confidence interval for the proportion of US residents who think marijuana should be made legal, and interpret it in the context of the data. (c) A critic points out that this 95% confidence interval is only accurate if the statistic follows a normal distribution, or if the normal model is a good approximation. Is this true for these data? Explain. (a) A news piece on this survey's findings states, "Majority of Americans think marijuana should be legalized. Based on your confidence interval, is this news piece's statement justified?

Answers

Answer:

see below

Step-by-step explanation:

(a) 48% is a sample statistic because it's based on the responses of 1,259 US residents. It's used to estimate a population parameter.

(b) We can calculate a 95% confidence interval for the proportion of US residents who support marijuana legalization. This interval provides a range, and we can be 95% confident that the true proportion falls within this range.

(c) The confidence interval calculation assumes the data follows a normal distribution. To use this method, we need a sufficiently large sample size, which is met in this case.

(d) To justify the news piece's statement that a majority of Americans support marijuana legalization, we need to check if the confidence interval includes values above 50%. If it does, then it supports the statement.
