Find the value of n so that the line perpendicular to y = (-1/4)x-1 passes through the points (n, 3) and (4,11).
Answer:
2
Step-by-step explanation:
You'll need to find the reciprocal of m. -1/4 is your is your m and when you find the reciprocal you flip the number to 4/1 or 4 and change the negative to a positive. Then graph (4,11), you don't need to worry about your y intercept, b, or -1. On your graph go down 4 and over one to the left because it's positive the line should be going like " / " <-- that. Keep going down until your y is three and whatever your x is, is your answer. Ex: (4,11) (3,7) (2,3). Hopefully, you understand :)

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternative hypotheses, test statistic, P-value, critical value(s), and state the final conclusion that addresses the original claim. A simple random sample of 25 filtered 100mm cigarettes is obtained, and the tar content of each cigarette is measure. The sample has a mean of 19.4 mg and a standard deviation of 3.52 mg. Use a 0.05 significance level to test the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg, which is the mean for unfiltered king size cigarettes. What do the results suggest about the effectiveness of the filters? What are the hypotheses? Identify the test statistic. Identify the P-value Identify the critical value(s). State the final conclusion that addresses the original claim. A. Fail to reject H0. There is insufficient evidence to support the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg. B. Reject H0. There is sufficient evidence to support the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg. C. Fail to reject H0. There is sufficient evidence to support the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg. D. Reject H0. There is insufficient evidence to support the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg. What do the results suggest, if anything, about the effectiveness of the filters? A. The results are inconclusive because the sample size is less than 30. B. The results suggest that the filtered cigarettes have the same tar content as unfiltered king size cigarettes. C. The results do not suggest that the filters are effective. D. The results suggest that the filters are effective. E. The results suggest that the filters increase the tar content.
Answer:
1) Option A: Fail to reject H0. There is insufficient evidence to support the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg.
2)Option D: The results suggest that the filters are effective
Step-by-step explanation:
We are given;
Sample size; n = 25
Sample mean; x' = 19.4 mg
Standard deviation; s = 3.52 mg
Population mean; μ = 21.1 mg
Let's state the hypotheses;
Null Hypothesis;H0: μ = 21.1 mg
Alternative Hypothesis; Ha; μ < 21.1 mg
Now, since sample size is less than 30,we will use a t-test.
Thus;
t = (x' – μ)/[s/√(n)]
t = (19.4 - 21.1)/(3.52/√25)
t = -2.415
Using an online p-value from t-score calculator as attached with the parameters t = -2.415, DF = 25 - 1 = 24, significance level = 0.05, one tailed, we have;
The p-value is 0.011885.
The calculated p-value is less than the significance level of 0.05. Thus, we will fail to reject the null hypothesis and conclude that there is insufficient evidence to support the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg.

Step-by-step explanation:
is negative 73 a natural number
No.
Negative numbers are not natural numbers.
Natural numbers are positive whole numbers.
1, 2, 3.... and so on.
Step-by-step explanation:
Hey there!!
(-73) is not a natural number.
The reason is natural number always starts from 1 and ends at infinity. But as the given number is -73 it is below 1. So, it's not a natural number.

Megan’s aunt have her a $100 gift card to Toys R Us for her birthday. Determine the price of the most expensive toy that Megan can buy with this gift card if the sales tax is currently 9.8%
Answer:
$91.07
Step-by-step explanation:
You cannot take off 9.8% from $100 to find the answer, since 9.8% of $100 is more tax than she will pay. The toy has to cost less than $100, so that when you add 9.8% tax the price you end up with exactly $100, and 9.8% of under $100 is less that 9.8% of $100. Maybe this is why you are a few cents off.
This is how you do it.
The price of the toy is unknown, so we'll cal it x.
When you add 9.8% tax to x, you want to end up with exactly $100.
x + 9.8% of x = 100
Write 9.8% as a decimal by dividing the percent by 100.
9.8% = 9.8/100 = 0.098
Now we have:
x + 0.098x = 100
Add like terms on the left side:
1.098x = 100
Divide both sides by 1.098:
x = 100/1.098
x = 91.07
Answer: The most expensive toy she can get costs $91.07 before tax.
Check:
We now add 9.8% tax to $91.07 and make sure the total cost including tax is no more than $100.
$91.07 + 9.8% of $91.07 =
= $91.07 + 0.098 * $91.07
= $91.07 + $8.92
= $99.99
It seems that you could try to spend one more cent, to really get to the $100 limit, so let's try $91.08 as the most expensive toy she can buy.
We now add 9.8% tax to $91.08 and see what the total cost including tax is.
$91.08 + 9.8% of $91.08 =
= $91.08 + 0.098 * $91.08
= $91.08 + $8.93
= $100.01
You see that if Megan gets a $91.08 toy, with tax, the total cost is $100.01, which is over the $100 limit, so the answer is indeed $91.07.
Jennifer is 3 years older than twice Zack’s age. The sum of their ages is 21. What are their ages?
Answer:
Jennifer is 15 and Zack is 6
Step-by-step explanation:
z+ (2z+3)=21
z+2z+3-3=21-3
z+2z=18
3z=18
3z/3=18/3
z=6
so plug 6 in for all the variables and their ages are
Zack-6
Jennifer-15

Which best describes the dimensions of a plane?
A plane has zero dimensions because it represents a location on the coordinate plane.
A plane has one dimension because it is made up of an infinite number of points.
A plane has two dimensions because it is a flat surface that has length and width but no depth.
A plane has three dimensions because it is made up of exactly three noncollinear points.
Answer: C) 2 dimensions; flat surface of length and width, but no depth
One way to think of a plane is to think of a flat sheet of paper that extends infinitely in all directions. The paper must be kept flat without any bends.
The statement that describes the dimensions of a plane is (c) a plane has two dimensions because it is a flat surface that has length and width but no depth.
To understand what a plane is, take a look at a flat surface such that:
PaperTop of a tableA white or black boardEtc.Notice that the above surfaces have just two dimensions (horizontal and vertical).
This is so because they are flat surfaces, and they have no heights
Hence, the statement that describes the dimensions of a plane is (c)

A ballroom is 60 ft long and 30 ft wide. Which of the following formulas is the correct formulas to determine the perimeter of the ballroom. a. P=2+60+2+30 b. P=60x30 c. P= 30x 30 + 60 x60 d. P= 2 x 60 + 2x 30
Answer:
The answer is D: 2 x 60 + 2 x 30
Step-by-step explanation:
The perimeter is the lengths of all the sides of a shape combined. Therefore, 60 is one side and 30 is the other side. Since the opposite sides are equal, there are two sides that equal 60 and two sides that equal 30.
So, 60 + 60 + 30 + 30.
60 + 60 = 60 x 2
30 + 30 = 30 x 2
Therefore, the answer is 60 x 2 + 30 x 2.
