The equation of a line that passes through the point (-5,-1) and has a gradient of −1/2. Leave your answer in the form y=mx+c
The number of advance tickets sold was 52.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 8 is an equation.
We have,
Advance tickets x = $5.00
Tickets purchased the night of the concert cost y = $10.50
Total number of tickets = 78
The total cost of the tickets = $533
Now,
x + y = 78
x = 78 - y
Substituting
5x + 10.50y = 533
5 (78 - y) + 10.50y = 533
390 - 5y + 10.50y = 533
5.50y = 533 - 390
5.50y = 143
y = 26
Now,
x = 78 - y
x = 78 - 26
x = 52
Thus,
52 advance tickets were sold.

what are the coordinates of a vertex of the hyperbola? (0, −4) (−3, 0) (0, 0) (0, 5)
Answers
The coordinates of a vertex of the hyperbola are (0, a) and (0, -a) for the hyperbola \(y^2/a^2 - x^2/b^2 = 1\), where "a" and "b" are constants.
the given answer is provided below:Given, the coordinates of a vertex of the hyperbola are (0, −4), (−3, 0), (0, 0), and (0, 5).In order to determine which of these coordinates represents the vertex, we need to identify the value of a, which is the distance from the center of the hyperbola to the vertex, for the hyperbola equation.If a hyperbola is expressed in the form of\(y^2/a^2 - x^2/b^2 = 1\), where "a" and "b" are constants, then the center of the hyperbola is the origin (0, 0), and the distance between the center and the vertex along the y-axis is "a".Let's go over each point:1. (0, −4)Since this coordinate is four units below the origin, the value of "a" should be 4. Hence, the coordinates of the vertex would be (0, 4) and (0, -4).2. (−3, 0)
Since this coordinate is three units to the left of the origin, it is not a vertex.3. (0, 0)Since this coordinate is at the center of the hyperbola, it is not a vertex.4. (0, 5)Since this coordinate is five units above the origin, the value of "a" should be 5. Hence, the coordinates of the vertex would be (0, 5) and (0, -5).Therefore, the coordinates of the vertices are (0, 4) and (0, -4), and (0, 5) and (0, -5) respectively.

your cell phone bill is $24.99 per month plus $0.16 for each text you send or receive. you have at most $29 to spend on your cell phone bill. What is the maximum number of texts you can send or receive next month?
Answers
The maximum number of texts to send or received in next month will be
25.
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
Cell phone bill = $24.99 per month
Cost of each text to send or receive = $0.16
Now,
You have at most $29 to spend on your cell phone bill.
Let number of text to send or receive = x
So, We can formulate;
$24.99 + $0.16x < $29
Solve for x as;
$24.99 + $0.16x < $29
Subtract 24.99 we get;
$0.16x < $29 - $24.99
$0.16x < $4.01
Divide by 0.16 we get;
x < 25.06
After rounding we get;
x < 25
Thus, The maximum number of texts to send or received in next month will be 25.

In the circle below, EG is a diameter. Suppose m FG = 116° and mZ GFH=69°. Find the following.
Answers
We can conclude that the, diameter m GFH = 21° and m GZH = 116°.
In geometry, the diameter of a circle is any straight line segment that has an endpoint on the circle and travels through its center.
Since the diameter is the length of the line that runs tangent to the two points at either end of the circle. Thus, diameter of a circle is the distance between its two furthest points.
We are given that angle EGF is a right angle (90°) because EG is a diameter.
We have been given that m FG = 116°, we can calculate m FGE by subtracting it from 180°;
m FGE = 180 degrees - m FG = 180 degrees - 116 degrees
m FGE = 64 degrees
m GFH = 180° - m ZGF - m ZGFH = 180° - 90° - 69°
m GFH = 21°
Finally, we can find m GZH by subtracting m FGE from 180° (the sum of triangle angles):
180° m GZH - 180°
m FGE - 64° = 116°
Therefore, m GFH = 21° and m GZH = 116°.

f(x)=
Answers
The equation of the quadratic function is: f(x) = 3x² - 18x - 48
To find the equation of a quadratic function in standard form, we need to use the zeros of the function and one additional point.
Given that the zeros are x = 8 and x = -2, we can write the equation in factored form as:
f(x) = a(x - 8)(x + 2)
To find the value of "a," we can use the fact that f(2) = -72.
Substituting x = 2 into the equation, we have:
-72 = a(2 - 8)(2 + 2)
Simplifying, we get:
-72 = a(-6)(4)
-72 = -24a
Dividing both sides by -24, we find:
3 = a
Now that we know the value of "a," we can rewrite the equation in standard form:
f(x) = 3(x - 8)(x + 2)
So, the equation of the quadratic function is:
f(x) = 3x² - 18x - 48

Answers
Using Central Limit Theorem (CLT) an approximate distribution of y is 0.2578, 0.1902 ,0.9963 , 0.9765.
To use the Central Limit Theorem (CLT), we need to find the mean and variance of the distribution of the sample mean Y.
The mean of the distribution of X is given by:
E[X] = ∫x f(x) dx = ∫x 3x^2 dx (from 0 to 1) = 3/4
The variance of the distribution of X is given by:
Var(X) = ∫(x - E[X])^2 f(x) dx = ∫(x - 3/4)^2 3x^2 dx (from 0 to 1) = 1/20
By the CLT, the sample mean Y is approximately normally distributed with mean μ = E[X] = 3/4 and variance σ^2 = Var(X)/n, where n is the sample size.
For each of the given values of n and σ^2, we can compute the standard deviation σ as σ = sqrt(σ^2/n), and then use the standard normal distribution to find the probability that Y falls in the given interval.
For example, for (n, σ^2) = (64, 0.021), we have:
σ = sqrt(0.021/64) = 0.077
Z1 = (0.7 - μ)/σ = (0.7 - 0.75)/0.077 ≈ -0.649
Z2 = (0.75 - μ)/σ = (0.75 - 0.75)/0.077 = 0
P(0.7 < Y < 0.75) = P(Z1 < Z < Z2) = P(-0.649 < Z < 0) = 0.2578 (from standard normal distribution table)
Similarly, for the other cases, we have:
(n, σ^2) = (64, 0.021)
P(0.7 < Y < 0.75) = 0.2578
(n, σ^2) = (64, 0.00033)
P(0.75 < Y < 0.8) = P(Z < 0.904) - P(Z < 0.309) ≈ 0.1902 (from standard normal distribution table)
(n, σ^2) = (256, 0.021)
P(0.7 < Y < 0.75) = P(Z < 2.597) - P(Z < -0.649) ≈ 0.9963 (from standard normal distribution table)
(n, σ^2) = (256, 0.00033)
P(0.75 < Y < 0.8) = P(Z < 2.128) - P(Z < 0.542) ≈ 0.9765 (from standard normal distribution table)

Overall percentage score: (65%) = 0.6; (80%) = 0.4.
= 0.6 × 0.65 + 0.4 × 0.80 (converting percentages to decimals) (converting percentages to decimals)

Answers
The measure of angle 4 is option (c) mAngle4 = 132⁰
Since the lines x and y are parallel, the corresponding angles formed by the transversal w are congruent. Therefore, we can write
mAngle2 = mAngle5
mAngle3 = mAngle6
mAngle4 = mAngle7
mAngle1 = mAngle8
We are given that mAngle6 = (11x + 8)° and mAngle7 = (12x – 4)°. We need to find the measure of mAngle4.
Using the fact that the sum of the angles around a point is 360°, we can write
mAngle2 + mAngle3 + mAngle4 + mAngle1 = 360°
Substituting the congruent angles, we get
mAngle5 + mAngle6 + mAngle7 + mAngle8 = 360°
Substituting the given values of mAngle6 and mAngle7, we get
mAngle5 + (11x + 8)° + (12x – 4)° + mAngle8 = 360°
Simplifying, we get
mAngle5 + 23x + 4° = 360°
mAngle5 + 23x = 356°
We are not given any information about mAngle5, so we cannot directly solve for x. However, we can use the fact that angles 5 and 7 are alternate interior angles formed by parallel lines and a transversal, and therefore they are congruent. Hence
mAngle5 = mAngle8
Substituting this in the equation above, we get
2mAngle5 + 23x = 356°
Solving for mAngle5, we get
mAngle5 = (356° - 23x)/2
Now, we can use the fact that mAngle2 + mAngle5 + mAngle6 = 180°, since angles 2, 5, and 6 form a straight line. Substituting the given values of mAngle6 and mAngle5, and using the fact that mAngle2 = mAngle5, we get
mAngle5 + mAngle5 + (11x + 8)° = 180°
2mAngle5 + 11x + 8° = 180°
2mAngle5 = 172° - 11x
Substituting the expression for mAngle5 we found earlier, we get
(356° - 23x)/2 = 86° - 5.5x
Solving for x, we get
23.5x = 270°
x = 11.4894°
Now, we can find the measure of mAngle4 by substituting x into the expression for mAngle7
mAngle7 = (12x – 4)°
mAngle4 = mAngle7 = 12(11.4894°) – 4°
≈ 132⁰
Therefore, the correct option is (c) mAngle4 = 132⁰

Answers
From the information about the students wearing Hoodie , expected number of students to not wearing Hoodie is equal to 210.
As given in the question,
Number of students entered in the gym = 20
Number of students wearing Hoodie = 14
Based upon the above information,
Number of students in the prep rally = 700
Let us consider x number of students wearing Hoodie in the prep rally
Therefore,
14: 20 and x : 700 are in proportion we get,
14/ 20 = x / 700
⇒ 20x = 14 × 700
⇒ x = (14 × 700) / 20
⇒ x= 490
Expected number of students not wearing Hoodie
