A circle has a center of (-6,0) and passes
through the point (-1,3). What is its radius?
Answer: 10
Step-by-step explanation:
Given that a circle has the center at
(6.0) and the circle passes through the point (2,−3).So the distance between these two points will give us the measure of the radius.So(x1,y1)=(6
So by using the distance formula the radius of the given circle is-r=√(x2−x1)2+(y2−y1)2r=√(2−6)2+(−3−0)2r=√16+9r=√25=5 unitsSo the diameter of the given circle is=2rd==2(5)d=10units

H0 describes the expected result of a statistical test if there is no difference between two or more groups being compared. True False
If there is no difference between any of the two or more groups being compared, H0 indicates the anticipated outcome of a statistical test. This statement is true.
H0, or the null hypothesis, represents the assumption that there is no significant difference between the groups being compared in a statistical test. It is the default hypothesis that is tested against an alternative hypothesis, H1, which states that there is a significant difference between the groups.
The null hypothesis is essential in hypothesis testing as it serves as the basis for determining whether the results of the test are statistically significant or due to chance. The statistical test is designed to reject the null hypothesis if the calculated p-value is less than the pre-determined significance level, indicating that the observed results are unlikely to have occurred by chance alone.
The acceptance or rejection of the null hypothesis has important implications for decision-making in various fields, such as medicine, psychology, and business. Therefore, it is crucial to carefully construct and test the null hypothesis to ensure that the results are accurate and meaningful.

The system of equations is consistent and has a unique solution at (-4, 1).
To solve the system of equations by graphing, we can plot the lines represented by each equation on a coordinate plane and find their point of intersection.
The given system of equations is:
1) 3x + y = -3
2) 6x - 6y = -30
Let's graph these equations:
For equation 1, 3x + y = -3, we can rewrite it as y = -3x - 3.
For equation 2, 6x - 6y = -30, we can simplify it to x - y = -5, and then y = x + 5.
Now, let's plot these lines on a graph:
The line for equation 1, y = -3x - 3, has a slope of -3 and y-intercept of -3. It will have a negative slope, and we can plot two points on the line: (0, -3) and (-1, 0).
The line for equation 2, y = x + 5, has a slope of 1 and y-intercept of 5. We can plot two points on this line as well: (0, 5) and (-5, 0).
Plotting these lines on a graph, we can see that they intersect at the point (-4, 1).
Now, let's analyze the system:
Since the lines intersect at a single point, the system is consistent. The solution to the system is the coordinates of the point of intersection, which is (-4, 1).
In summary, the system of equations is consistent and has a unique solution of x = -4 and y = 1.

A band wants to enter a contest that requires traveling expenses. They need at least $1,150 to cover all of the expenses. They have already saved $700. They are selling shirts with a profit of $7.00 per shirt to earn the remaining money.
Part A
Which inequality represents the minimum number of shirts, n, the band must sell to earn the remaining money?
7n+700≤1,1507 n plus 700 is less than or equal to 1 comma 150
7(n+700)≤1,1507 times open paren n plus 700 close paren is less than or equal to 1 comma 150
7n+700≥1,1507 n plus 700 is greater than or equal to 1 comma 150
7(n+700)≥1,1507 times open paren n plus 700 close paren is greater than or equal to 1 comma 150
Question 2
Part B
What is the minimum number of shirts the band must sell to earn the remaining money?
The correct inequality is 7n + 700 ≥ 1,150. The band must sell a minimum of 65 shirts to earn the remaining money. That is the minimum number of shirts the band must sell to earn the remaining money is 65.
To determine the minimum number of shirts the band must sell, we need to consider the profit per shirt. The profit per shirt is given as $7.00. Let's denote the number of shirts as 'n'.
The total earnings from selling shirts can be calculated by multiplying the profit per shirt with the number of shirts sold. Therefore, the total earnings from selling 'n' shirts would be 7n.
Since the band has already saved $700, their total earnings (7n) plus their savings ($700) should be greater than or equal to the total expenses of $1,150. Thus, the inequality representing the minimum number of shirts the band must sell is:
7n + 700 ≥ 1,150
To solve this inequality, we can subtract 700 from both sides:
7n ≥ 450
Then, dividing both sides by 7:
n ≥ 64.29
Since the number of shirts cannot be fractional, the band must sell at least 65 shirts (rounding up from 64.29) to earn the remaining money and cover their expenses.

From the data,
We have to determine the value of x.
The given equation is: 18x-16=-12x-4
For determining the value of x, we will first shift the like terms on one side of the equation.
So, for solving the value of x we will shift the terms containing x and the constant on both sides of the equation.
So, shifting -12x from the right-hand side of the equation to the left-hand side of the equation,
We will get it as:
18x+12x = -4+16

a) The set Z (integers) is not open.
b) The set O = ∩(i=1 to ∞)Oi, where Oi = (-1/i, 1/i), is open.
a) The set Z (integers) is not open.
An open set is a set that does not contain its boundary points.
In the case of the set of integers, every point in the set is a boundary point since there are no open intervals around any integer that lie entirely within the set.
Therefore, the set Z is not open.
b) The set O = ∩(i=1 to ∞)Oi, where Oi = (-1/i, 1/i), is open.
Each individual interval Oi = (-1/i, 1/i) is an open interval, and the intersection of open sets is also an open set.
This means that for any point x in O, there exists an open interval around x that is entirely contained within O.
Therefore, O is an open set.
Neither set Z nor set O is closed.
In the case of set Z, it does not contain all of its boundary points since the boundary points include all non-integer numbers.
set O is not closed since it does not contain its boundary points, which include the points -1 and 1.

in a large population, 54 % of the people have been vaccinated. if 4 people are randomly selected, what is the probability that at least one of them has been vaccinated?
The probability that at least one of them has been vaccinated is 0.9552
Probability:
Probability defines the possible occurrence of any particular required event.
Given,
Here we need to find in a large population, 54 % of the people have been vaccinated. if 4 people are randomly selected, what is the probability that at least one of them has been vaccinated.
Here we have to know that,
The situation where at least one out of 4 are vaccinated includes all but one possibility, that which none of the 4 are vaccinated.
The sum of all probabilities must equal 1.
Let Q be probability none of the 4 are vaccinated.
Let P be probability that at least 1 is vaccinated.
Then the probability is calculated as,
P = 1 - Q
Now if 54% are vaccinated, then 46% are not vaccinated.
Thus any given person has a probability of 0.46 of not being vaccinated.
=> Q = (0.46)⁴
=> Q = 0.0448
Then apply the value to the formula,
=> P = 1 - 0.0448
=> P = 0.9552
Therefore, the probability that at least one of them has been vaccinated 0.9552.
