passes through the point (-3,-7) and is parallel to the -axis
Answers
Answer:
y = - 7
Step-by-step explanation:
Assuming you require the equation
The equation of a line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (- 3, - 7) with y- coordinate - 7, thus
y = - 7 ← equation of line

using a conservative sample size, how many randomly selected businesses should be contacted to construct a 99% confidence interval for the proportion of businesses that plan to hire employees within the next sixty days to within a 4% margin of error?
Answers
Rounding up to the nearest whole number, we would need a sample size of at least 105 businesses to construct a 99% confidence interval with a 4% margin of error.
To determine the sample size required to construct a 99% confidence interval for the proportion of businesses with a 4% margin of error, we need to use the formula:
n = (Z^2 * p * (1-p)) / E^2
Where:
n = sample size
Z = Z-score corresponding to the desired confidence level (99% confidence level corresponds to a Z-score of approximately 2.576)
p = estimated proportion (since we don't have an estimate, we can assume p = 0.5 to get a conservative estimate)
E = margin of error (0.04 or 4%)
Plugging in the values, we have:
n = (2.576^2 * 0.5 * (1-0.5)) / 0.04^2
n = (6.638176 * 0.25) / 0.0016
n ≈ 104.364

For any given event, the probability of that event and the probability of the _______ of the event must sum to one.
Answers
For any given event, the probability of that event and the probability of the non-occurrence of the event must sum to one.
A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
The probability of occurrence formula, also known to some as the “probability of occurrence formula PMP” is a tool for determining the chance that a given risk will occur. The formula requires two data points: number of favourable events possible and the total number of events possible.
Non occurrence patterns identifies the absence of events when detecting a pattern.

if outliers are present, but their removal is justified and results in a data set for which the z test is appropriate, then
Answers
If outliers are present in a dataset, but their removal is justified and results in a data set for which the z-test is appropriate, then the z-test can be used to test a hypothesis about the mean of the dataset.
The z-test is a parametric test that assumes the data is normally distributed and that the population standard deviation is known or can be estimated from the sample.
Outliers can affect the normality assumption and the estimation of the standard deviation, leading to incorrect results if not handled properly.
If outliers are identified and can be removed based on a valid justification (e.g., measurement error, data entry error), then the resulting dataset can be checked for normality using methods such as the Shapiro-Wilk test or visual inspection of a normal probability plot.
If the dataset is approximately normal, and the sample size is sufficiently large, then the z-test can be used to test a hypothesis about the mean.
However,
It is important to note that outlier removal should be done with caution and based on valid justifications. ++
Arbitrarily removing outliers without justification can lead to bias and incorrect conclusions.
Additionally,
There are also non-parametric tests that can be used to test hypotheses about the median or other measures of central tendency that are robust to outliers.

vikas ranks 9th in the class. how many students are there in the class? statements : 1) his friend got the 35th rank which is the last rank. ii) his rank from the last is 27th
Answers
There are total 35 students in the class.
Given that,
Vikas ranks 9th in the class,
Assume that there are 'n' number of students in the class
Therefore,
There are 8 students who have scored better than him.
So, The total number of students with a rank better or equal to Vikas,
= 8 + 1 (Vikas himself)
= 9.
Now, his friend got the 35th rank which is the last rank
This means that there are a total of 35 students in the class.
Also, also given that,
Vikas's rank from the last is 27th,
This means that there are 26 students who have scored lower than Vikas.
So, the total number of students with a rank worse or equal to Vikas,
= 26 + 1 (Vikas himself)
= 27.
Therefore, The total number of students in the class = 35.

D. ∀x∃y(¬P(x)∨¬Q(x,y))
Answers
The logical expression that is equivalent to ¬∀x∃y(P(x)∧Q(x,y)) is ∀x∃y(¬P(x)∨¬Q(x,y)) i.e., the correct option is option D.
To determine the equivalent logical expression, we need to apply De Morgan's laws and quantifier negation rules.
Starting with the given expression ¬∀x∃y(P(x)∧Q(x,y)), let's break it down step by step:
Apply the negation of the universal quantifier (∀x) to get ∃x¬∃y(P(x)∧Q(x,y)).
This step changes the universal quantifier (∀x) to an existential quantifier (∃x) and negates the following expression.
Apply the negation of the existential quantifier (∃y) to get ∃x∀y¬(P(x)∧Q(x,y)).
This step changes the existential quantifier (∃y) to a universal quantifier (∀y) and negates the following expression.
Apply De Morgan's law to the negation of the conjunction (P(x)∧Q(x,y)) to get ∃x∀y(¬P(x)∨¬Q(x,y)).
This step distributes the negation inside the parentheses and changes the conjunction (∧) to a disjunction (∨).
Therefore, the equivalent logical expression is option D. ∀x∃y(¬P(x)∨¬Q(x,y)).

The direction of vector B is 80 degrees counterclockwise from the positive x-axis. The magnitude of vector A + B is approximately 9.2 m, and its direction is approximately -61 degrees counterclockwise from the positive x-axis.
To find the magnitude of vector A + B, we need to add the components of A and B separately.
Let's assume vector A is given by (A_x, A_y). Adding A and B, we have (A_x + B_x, A_y + B_y). Given that A = (-3.2 m) x^ + (2.7 m) y^, and B = (-1.1 m) x^ + (5.3 m) y^, we can add their components: (-3.2 m - 1.1 m, 2.7 m + 5.3 m) = (-4.3 m, 8 m).
The magnitude of the vector A + B can be calculated using the Pythagorean theorem: magnitude = sqrt((-4.3 m)^2 + (8 m)^2) ≈ 9.2 m.
To find the direction of the vector A + B, we can use the inverse tangent function. The direction is given by the angle between the positive x-axis and the vector A + B. Using the components of A + B, we find the angle: angle = arctan((8 m) / (-4.3 m)) ≈ -61 degrees counterclockwise from the positive x-axis.
Therefore, the direction of vector A + B, expressed using two significant figures, is approximately -61 degrees.
