Two expressions with equal sign is called as Equation. The rating of a brand that costs $3.00 per bag is 7.
What is equation?Two expressions with equal sign is called as Equation.
A simple linear regression equation is used to estimate the value of the dependent variable based upon the independent variable.
The general form of a simple linear regression equation is:
y=a+bx
Here,
y = dependent variable
x = independent variable
a = intercept
b = slope
The output of the least squares regression analysis for predicting rating from price is provided.
So, the dependent variable is the ratings and the independent variable is the price.
The regression equation for predicting rating from price is:
y=0.39+2.52x
Predict the rating of a brand that costs $3.00 per bag as follows:
y=0.39+(2.52*$3.00)
=0.39+7.56
=7.17
=7 approximately.
Thus, the rating of a brand that costs $3.00 per bag is 7.

Your friend says that the magnitude of vector (8 , 3) is 4 times that of vector (2 , 3) since 8 is 4 times 2 . Explain why your friend's statement is incorrect.
With the help of the Magnitude formula, we can say that Magnitude of 1st vector is more than the 2nd vector.
A vector is an object that has both magnitude and direction. To find the size of a vector, we need to calculate the length of the vector. Variables such as velocity, distance, force, and momentum are vector variables. But velocity, mass, distance, volume, temperature, etc. is a scalar quantity. A vector has both magnitude and direction, while a scalar has only one magnitude.
The Magnitude of a vector is the length of the vector. The Magnitude value of vector a is represented by ∥a∥.
For a two-dimensional vector a= (a1, a2), the formula for its Magnitude is written below.
By using the Magnitude formula, we can say that Magnitude of 1st vector is more than the 2nd vector.

A woman sold an article for $200,000 and made a profit of 25%. Find the cost price of the article.
Answer:
The original cost is 160,000
Step-by-step explanation:
X x 25/100 + X = 200,000
25X/100 + X =200,000
X= 200,000-25X/100
X= (20,000,000-25X) / 100
100X = 20,000,000-25X
125X = 20,000,000
X = 160000

help these 3 questions (calculating positive and negative numbers)
Answer:
1st question: $-4.5
2nd question: 32
3rd question: -27
Step-by-step explanation:
1st question:
Alan's octopus is $-7 dollars right now. After reloading $50 dollars in, it just means that he put $50 dollars in. We can work it out like this:
-7+50=43 (you can switch the equation around but the sign has to go with it: 50-7)
Now Alan's octopus has $43 in it. It then says that Alan spends $48.5 for a really expensive pencil case. You can calculate it like this:
43-48.5=-4.5 (43-48.5 is the same as 43.0-48.5 and you can work it out on a number line).
This leaves Alan's octopus to only have $-4.5 which means he is in debt again.
2nd question:
I can make it out that it says: Tony adds -18 to +50. Find the results (I hope I saw it right). The equation of it would look like:
-18+50 or you can flip it around but the sign has to go with them like in question one which will look like this: 50-18=32. So the result of Tony's problem is 32.
3rd question:
Patty subtracts +11 from -16. Find the results.
First of all don't do this 11-16 because that would be 16 subtracted from 11 which is wrong because 1, the sign completely disappears unless you make it -16 plus 11 and 2, it's order would be incorrect. The correct equation should look like this:
-16-11=-27 ( -16-(+11) positive combined with negative is negative).
You can think of it like this: If it's the same sign that's addition or subtraction eg. -4-2 or +6+8, you just add it up together and put the sign in front which you would not have to do for the addition one unless you are asked to.

is y= -x³+2x linear or nonlinear?
Answer:
nonlinear
Step-by-step explanation:
In a linear equation, there are no multiplications of variables by variables.
x³ means x × x × x, so there is a multiplication of variables in the equation, and the equation is not linear.
Answer:
Non-linear

Since one of the terms has an exponent of 3, this is a cubic equation, a third degree equation. It is a curve and therefore, NOT a linear equation.

Write each expression as a single logarithm.
log₆5+log₆x
The expression log₆5+log₆x as a single logarithm is log₆5x.
The logarithm is exponent's inverse function in mathematics. This indicates that the exponent to which a fixed number(say a) at base b, must be raised in order to create a number x, is represented by the logarithm of that number.
For example if 8=2³ can be written in the logarithmic form as
log₂8=3.
The general properties of logarithm for a fixed base are:
logₐa=1logₐx+logₐy=logₐxylogₐx-logₐy=logₐ(x/y)logₐxⁿ=n logₐxlogₓy=(logₐy)/(logₐx)Here the given logarithmic expression is (log₆5+log₆x)
So according to the properties of logarithms we can use the above property "logₐx+logₐy=logₐxy" to simplify the given expression.
Therefore:
log₆5+log₆x
=log₆(5×x)
=log₆5x
Hence written as a single logarithm the expression is log₆5x.

PLEASE HELP ME. The table gives the number of beads needed to make bracelets of certain lengths. Suppose you graph the ordered pairs (bracelet length, number of beads) on the coordinate plane. Would the point (10.5, 42) make sense in this context? Explain.
Using a proportional relationship, it is found that point (10.5, 42) makes sense in this context, as when x = 10.5, y = 42 is the output of the relation.
What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the multiplication of the input variable and the constant of proportionality, defined by k, in the case of a direct relationship, according to the following rule:
y = kx
For the case of an inverse relationship, we have that:
y = k/x.
From the table in this problem, the constant is given as follows:
k = 28/7 = 32/8 = 36/9 = 40/10 = 4.
Hence the relation is modeled as follows:
y = 4x.
In which:
x is the bracelet length in inches.y is the number of beads.When x = 10.5, we have that:
y = 4(10.5) = 42.
Hence point (10.5, 42) makes sense in this context.

(√(2x + 3))² = 7²
Solving the square
2x + 3 = 49
Shifting 3 to the Right Hand Side of the equation
2x = 49 - 3
Performing subtraction on Right Hand Side of the equation
2x = 45
Shifting 2 to the Right Hand Side of the equation
x = 45 ÷ 2
