Answers
According to the representation of the linear model, the balloon's height is zero feet after 15 seconds.
Explain about the inear regression?Depending on the context, the word "linear model" in statistics might signify many things.
The phrase is frequently used interchangeably with a linear regression model since it most frequently relates to regression models.
The phrase has a different connotation when applied to time series analysis.
In each instance, "linear" refers to a subclass of models for which the complexity of the underlying statistical theory can be greatly reduced.
The linear model shows that the water balloon is launched from a height of 40 feet above.
The linear model shows that the water balloon is launched from a height of 40 feet above.
Now, the balloon rises to a height of 70 feet before falling back to the ground as a result of gravity.
After about ten seconds, the balloon lands on the surface and makes a splash.
The balloon will therefore stay on the ground for a while longer.
As a result, the balloon's height at time 15 seconds is always 0 feet, according to the linear model.

A two-piece set of luggage costs 122 If sold individually, the large bag costs 30 more than the small bag. What are the individual costs for each bag?
Answers
Let x be the cost of the small bag.
The large bag costs x + 30 more than the small bag.
So the cost of the large bag is x + (x + 30) = 2x + 30
The two-piece set of luggage cost is the sum of the cost of the small and large bag, so
122 = x + (2x + 30)
Solving this equation for x, we get:
x = 42
Therefore, the small bag costs 42 dollars and the large bag costs 2*42 +30 = 114 dollars.

The numeral preceding 100000 base 2
Answers
One less than the given number is known as preceding number whereas one more than the given number is the succeeding number.
The logics followed in order to find them:
Base numbers work exactly the same as base 10 numbers (the ones we use on a daily basis).
Take for example, in a decimal system, we have 10 digits available:
0,1,2,3,4,5,6,7,8,9.
When counting, when we get to the 9, we start over again, but writing a 1 to the left.
0,1,2,3,4,5,6,7,8,9,10,11,12....20,21,22,23....,90,91,92,93,94,95,96,97,98,99,10
When reaching 99, we have no more digits to use, so we start the count again and go from 99 to 100.
The same works with any other base number, take for example the base 7 number.
When counting in base 7, we only have 7 digits available: (0,1,2,3,4,5,6) So when 0_{7},each the digit 6, we go immediately to 10, like this:
It went from 6 to 10 and from 16 to 20. This is because in base 7, there is no digits from 7 to 9, so we have directly to 20.
So, if working with decimal numbers, the previous value for 640 would be 639, but notice that in base 7,
There is no such thing as the digit 9, so the greatest digit we can use there 6,
Therefore, the previous value for the number would be. The next number would be because the 1 does exist for a base 7 system.

Step 2 Dilate circle B to be congruent to circle A using scale factor of k equals r sub two over r sub one equals two thirds period
Step 3 When an object is dilated, the dilated object is similar to the pre-image, thus the two circles are similar.
Which step is incorrect, and how can it be fixed?
Group of answer choices
All steps are correct
Step 1, circle B should have been translated 7 units right and 9 units up
Step 3, replace "dilated" with "translated"
Step 2, circle B should have been dilated using scale factor of k equals r sub two over r sub one equals three halves
Answers
The required incorrect step is step 1, circle B should have been translated 7 units right and 9 units up. Option A is correct.
What is a circle?The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on the coordinate plane and r is the radius of the circle.
Here,
Circle A with a center at (3, 4) and a radius of 2 is similar to circle B with a center at (−4, −5) and a radius of 3.

Answers
The final result would be a feasible set with arrows indicating the direction of increase of the objective function z.
The feasible set can be found by solving the system of equations g1, g2, g3 and g4.
g1: -3x - 2y = -6
g2: 5x - 2y = 40
g3: 2x + 4y - 8 = 0
g4: x + y = 5
Solving for x and y,
We will get the coordinates of the feasible set: (2,2), (5,0), (0,5).
Next, we find the vectors that are parallel to each boundary:
g1: (-3, -2),
g2: (5, -2),
g3: (2, 4),
g4: (1,1)
To determine the direction in which the objective function z increases, we compute z.v1 for each boundary:
z.v1 = (-3, -2) * (-3, -6) = 18 + 12 = 30
z.v2 = (5, -2) * (-3, -6) = -15 - 12 = -27
z.v3 = (2, 4) * (-3, -6) = -6 - 24 = -30
z.v4 = (1,1) * (-3, -6) = -3 - 6 = -9
Based on the results, we can see that the objective function z increases in the direction of vector v2 and decreases in the directions of vectors v1, v3, and v4.
To put arrows on each boundary indicating the direction in which the objective function z increases, we would place arrows pointing towards the direction of vector v2 on g2 and away from the direction of vector v2 on g1, g3 and g4.

[tex](a + b)^n = C(n, 0)a^n b^0 + C(n, 1)a^(n-1) b^1 + ... + C(n, n-1)a^1 b^(n-1) + C(n, n)a^0 b^n[/tex]
Where C(n, k) is the binomial coefficient, given by C(n, k) = n! / (k! (n - k)!).
In this case, a = 2x and b = 8. So, substituting these values into the binomial theorem:
[tex](2x + 8)^6 = C(6, 0)(2x)^6 8^0 + C(6, 1)(2x)^5 8^1 + ... + C(6, 5)(2x)^1 8^5 + C(6, 6)(2x)^0 8^6[/tex]
Expanding each term, and combining like terms, we get:
[tex](2x + 8)^6 = 64x^6 + 1536x^5 + 15360x^4 + 819204x^3 + 245760x^2 + 393216x + 262144[/tex]

The function for distance jogged is d(t) = 3.3t and the inverse of the function is d(t)⁻¹ = 3.3/t.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Let, 'd' be the distance covered in miles, and 't' is the time in hours.
Therefore, From the given information d(t) = 3.3t.
Let, d(t) = y.
So, y = 3.3t.
t = 3.3/y.

What is the function of coordinate plane?By portraying the inputs and outputs as a horizontal number line (the x axis) and a vertical number line (the y axis), respectively, the Cartesian coordinate plane enables us to perceive ordered pairs. The quantity in the x component is moved horizontally. Move to the right if x is positive. Move to the left if x is negative.
Here,
Given :
=> -30 , -20 ,-10 ,0 ,10, 20 , 30
=> So ,
Y coordinates comes out to be :
=> -3 , -2, -1 , 0, 1,2,3
An ordered pair of numbers, or x-coordinate and y-coordinate on the x-axis respectively, can be used to represent each point.
Written in parenthesis are ordered pairings (x-coordinate, y-coordinate). The source is situated at (0,0).
Check your coordinates, which are two numbers enclosed in parenthesis and separated by a comma, to see how to graph a point on the coordinate plane.

A box contains orange balls and green balls. The number of green balls is seven more than 2 times the number of orange balls. If there are 73 balls altogether, then how many green balls and orange balls are there in the box?
Answers
Answer:
52-green
15-orange
Step-by-step explanation:
g + o = 67
g = green, o = orange, x = total = 3o + 7
use substitution: (3o + 7) + o = 67
solve for o:4o + 7 = 67
4o = 60o
= 60/4 = 15
solve for g:
g + 15 = 67
g = 52

PROBABLITY
Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.
