Answer:
Below.
Step-by-step explanation:
Complete the multiplication and the equation becomes
4/6−3/6=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
4−3/6=1/6
This fraction cannot be reduced.
Therefore:
2/3−1/2=16
Solution by Formulas
Apply the fractions formula for subtraction, to
2/3−1/2
and solve
(2×2)−(1×3)3×2
=4−3/6
=1/6
Therefore:
2/3−1/2=1/6

The given expression 7x - y = -9 in the slope intercept form can be represented as y = 7x + 9.
The expression given to us is -
7x - y = -9
We have to represent this in the slope intercept form.
The slope intercept form can be represented as -
y = mx + c
where, y = y coordinate of the line
m = slope of the line
x = x coordinate of the line
c = y intercept of the line
Thus, representing the given expression in the slope intercept form, we have
7x - y = -9
=> -y = -7x - 9
=> y = 7x + 9
Thus, the given expression in the slope intercept form can be represented as y = 7x + 9.

Number 8 I need help really bad
Answer:
See below.
Step-by-step explanation:
So we have the parent function:
\(f(x)=x^2\)
And it was transformed into:
\(g(x)=(3x)^2+6\)
First, the +6 at the very end simply tells us that the graph was shifted upwards by 6 units.
For the (3x), this is essentially saying that:
\(f(x)=x^2\)
If we use 3x for x:
\(f(3x)=(3x)^2\)
Therefore, we essentially multiplied the x variable by 3.
In other words, this is a horizontal compression by a factor of 3.
So, our transformations are:
1) 6 units upwards
2) Horizontal compression by 3
If the mean is greater than the median, the data is likely: Group of answer choices Symmetric Normally distributed Left-skewed Right-skewed
If the mean is greater than the median, the data is likely Right-skewed.
In mathematics, the mean is the average of a set of data, which is calculated by adding all the numbers together and then dividing the result by the total number of numbers. Right-skewed distributions have long right tails and are characterized by having a mean that is greater than the median. There are two different sorts of means that may be calculated: the arithmetic mean and the geometric mean. The arithmetic mean is calculated by adding all of the numbers in a set and dividing by the total number of integers in the set.
Therefore, the answer is right-skewed. A data set that is skewed to the right is one where the tail to the right of the data clusters is longer than the tail to the left of the data clusters. This means that the data set will have a mean value that is greater than the median.

Use the given information to find the unknown value. Y varies inversely with the cube of x. When x=5, then y=1. Find y when x=1
Answer:
125
Step-by-step explanation:
y = 1k/x^3 I am trying to find the constant k. I will use the information that I have been given to find k
1 = k/5^3
1 = k/125 Multiply both sides by 125
125 = k
Now, we will find y when x = 1
y = 125/1^3
y = 125
The value of y is 125 when x is 1.
Write the function y as a function of x, i.e., y = f(x), and then solve for x as a function of y, to determine the inverse of a function.
y = 1k/x^3 I am trying to find the constant k. I will use the information that I have been given to find k
1 = k/5^3
1 = k/125
Multiply both sides by 125
125 = k

The unit rate would be 250 calories per mile which is the slope of the given linear function.
What is the unit rate?The unit rate of a linear function is defined as the slope of the linear function.
The slope is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
The given graph represents the number of miles he ran and the number of calories burned.
Taking two points as per the given graph :(2, 500), (6, 1500)
Let
x₁ = 2, y₁ = 500
x₂ = 6, y₂ = 1500
Substitute values in the formula to get
unit rate = (1500 - 500)/(6 - 2)

a florist determines the probabilities for the number of flower arrangements they deliver each day. x 19 20 21 22 23 p ( x ) 0.21 0.23 0.30 0.13 0.13 find the mean, variance, and standard deviation of the distribution rounded to 4 decimal places.
For the given distribution the mean is 20.74 , the variance is 1.652 and the standard deviation is 1.2853 .
In the question ,
probabilities are given ,
the mean is given by the formula,
mean = \(\sum\)x*p(x) ,
we get ,
mean = 19*0.21 + 20*0.23 + 21*0.30 + 22*0.13 + 23*0.13
= 3.99 + 4.6 + 6.3 + 2.86 + 2.99
= 20.74
For calculating the Variance we need to subtract the mean for every value x, then we square the result and multiply it by the respectively probability .
19 - 20.74 = -1.74 = (-1.74)²× 0.21 = 0.6357
20 - 20.74 = -0.74 = (-0.74)²× 0.23 = 0.1259
21 - 20.74 = 0.26 = (0.26)²× 0.30 = 0.0202
22 - 20.74 = 1.26 = (1.26)²× 0.13 = 0.2063
23 - 20.74 = 2.26 = (2.26)²× 0.13 = 0.6639
The variance = 0.6357 + 0.1259 + 0.0202 + 0.2063 + 0.6639
= 1.652
the standard deviation = √variance
= √1.652
= 1.2853
Therefore , the values are mean is 20.74 , the variance is 1.652 and standard deviation is 1.2853 .

the angle \theta 1θ 1 theta, start subscript, 1, end subscript is located in quadrant \text{iii}iiistart text, i, i, i, end text, and \sin(\theta 1)
The value of the angle θ₁, located in Quadrant IV with sin(θ₁) = -13/85, is such that cosθ₁ = 84/85.
In the given scenario, the angle θ₁ is located in Quadrant IV and sin(θ₁) is given as -13/85. We can use the trigonometric identity to determine the value of cosθ₁.
Using the Pythagorean identity sin²θ + cos²θ = 1, we can substitute sin(θ₁) = -13/85:
(-13/85)² + cos²θ₁ = 1
Simplifying:
169/7225 + cos²θ₁ = 1
cos²θ₁ = 1 - 169/7225
cos²θ₁ = (7225 - 169)/7225
cos²θ₁ = 7056/7225
Taking the square root of both sides, we get:
cosθ₁ = √(7056/7225)
Since the angle θ₁ is located in Quadrant IV where cosθ₁ is positive, the value of cosθ₁ is:
cosθ₁ = √(7056/7225)
Simplifying the square root:
cosθ₁ = 84/85
Therefore, the value of the angle cosθ₁ is 84/85.

The volume of a cone-shaped hole is 48 pi ft cubed . If the hole is 4 ft deep, what is the radius of the hole?
To find the radius of the cone-shaped hole, we need to use the formula for the volume of a cone, which is V = (1/3)πr^2h, where V is the volume, r is the radius, and h is the height. The radius of the cone-shaped hole is 6 feet.
We know that the volume of the hole is 48π ft^3 and the height is 4 ft, so we can plug in those values and solve for the radius:
48π = (1/3)πr^2(4)
48 = (1/3)r^2(4)
48 = (4/3)r^2
r^2 = 36
r = 6
Therefore, the radius of the cone-shaped hole is 6 ft.
To find the radius of the cone-shaped hole, we can use the formula for the volume of a cone:
Volume = (1/3) * pi * r^2 * h
where:
- Volume = 48 pi ft^3
- h = depth (4 ft)
- r = radius (what we're trying to find)
First, plug in the given values:
48 pi = (1/3) * pi * r^2 * 4
Now, we can simplify and solve for r:
48 pi = (4/3) * pi * r^2
Divide both sides by (4/3) * pi:
r^2 = 48 pi / (4/3) * pi
r^2 = 48 * (3/4)
r^2 = 36
Take the square root of both sides:
r = √36
r = 6 ft
The radius of the cone-shaped hole is 6 feet.

If the forecast for two consecutive periods is 1,500 and 1,400 and the actual demand is 1,200 and 1,500 , then the mean absolute deviation is 1) 500 2) 700 3) 200 4) 100
200 is the mean absolute deviation. Therefore, choice three (200) is the right one.
How to calculate the mean absolute deviation
The absolute difference between the predicted and actual values must be determined, added together, and divided by the total number of periods.
Forecasted values are as follows: 1,500 and 1,400
Values in actuality: 1,200 and 1,500
Absolute differences:
|1,500 - 1,200| = 300
|1,400 - 1,500| = 100
Now, we calculate the MAD:
MAD = (300 + 100) / 2 = 400 / 2 = 200

For the numbers, we need a positive number and a negative number (two negatives make a positive). We can eliminate C because at first -3 multiplied by 2 is -6. However, when -3 is added to 2 we get -1.
If we expand A, it makes the expression that needs to be factorised because...

(x - 3y)² = (x - 3y)(x - 3y) = x² - 6xy + 9y²
Expand the second term:
3(x + y)(x − 4y) = 3(x² - 4xy + xy - 4y²) = 3(x² - 3xy - 4y²)
Expand the third term:
x(3x + 4y + 3) = 3x² + 4xy + 3x
Now, let's combine all the expanded terms:

(b) Given the matrix D = k 0 0 3 k² k³ 0 kª k³ kº k k k 0 0 0 k¹⁰ Find all possible value(s) of k if det(D) = 1024."
To find the possible values of k, we need to calculate the determinant of matrix D and set it equal to 1024.
Given matrix D:
D = | k 0 0 |
| 3 k² k³ |
| 0 kª k³ kº |
| k k k |
| 0 0 0 |
| k¹⁰ |
The determinant of D can be calculated by expanding along the first row or the first column. Let's expand along the first row:
det(D) = k(det | k³ k k |
| 0 k³ kº |
| 0 0 k¹⁰ |)
- 0(det | 3 k² k³ |
| 0 kª k³ |
| k k k |)
+ 0(det | 3 k² k³ |
| k k k |
| k k k |)
Simplifying further, we have:
det(D) = k(det | k³ k k |
| 0 k³ kº |
| 0 0 k¹⁰ |)
Now, we can calculate the determinant of the 3x3 submatrix:
det | k³ k k |
| 0 k³ kº |
| 0 0 k¹⁰ |
This determinant can be found by expanding along the first row or the first column. Expanding along the first row gives us:
det = k(k³(kº) - 0(k)) - 0(0(k¹⁰)) = k⁴kº = k⁴+kº
Now, we can set det(D) equal to 1024 and solve for k:
k⁴+kº = 1024
Since we are looking for all possible values of k, we need to solve this equation for k. However, solving this equation may require numerical methods or approximations, as it is a quartic equation.
