these data?
Answer:
Step-by-step explanation:
I can tell you how to do this on your calculator, but I have no idea what kind of calculator you have and the methods are different for the various TI graphing calculators, so I'll just tell you that your answer is the last choice given. It's a terrible fit, but if the instructions say linear, the last choice is the equation that the calculator gives.
The regression equation for Y is: ŷ = -0.223X + 20.523
What is Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Sum of X = 15
Sum of Y = 99.27
Mean X = 3
Mean Y = 19.854
The sum of squares (SSX) = 10
The sum of products (SP) = -2.23
Regression Equation = ŷ = bX + a
b = SP/SSₓ = -2.23/10 = -0.223
a = My - bMₓ = 19.85 - (-0.22*3) = 20.523
ŷ = -0.223X + 20.523

The value of the equation ( x⁶ - x ) / 4y = 1025/4 when x = -4 and y = 4
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = ( x⁶ - x ) / 4y be equation (1)
The value of x = -4
The value of y = 4
Substituting the values of x and y in equation (1) , we get
A = ( ( -4 )⁶ - ( -4 ) ) / ( 4 x 4 )
On simplifying the equation , we get
A = ( 4096 + 4 ) / 16
A = 4100 / 16
A = 1025 / 4
Therefore , the value of A is 1025/4
Hence , the value of the equation is 1025/4

1. Write and solve an inequality that represents the number of months the center could
rent games from NetGames with its $175. Explain the solution in terms of the problem.
Solution :
Given that the Centre is signing up for a rental game service online rather than buying the game.
The monthly fees and the equipment cost of the two services that is the 'Anytime games' and the 'Netgames' are attached below.
Therefore, the inequality which represent the number that the center can rent the online games from the NetGames is :
175 - 8m ≥ 99
175 - 8m - 99 ≥ 99 - 99 (Subtracting 99 from both side of the inequality)
76 - 8m ≥ 0 (Simplify)
76 - 8m -76 ≥ 0 - 76 (Subtracting 76 from both side of the inequality)
- 8m ≥ - 76 (Simplify)
8m ≥ 76 (removing the minus sign form both sides)

The median is 5.
Step-by-step explanation:
First we need to take the data and make it into a set :
3, 3, 4, 5, 5, 5, 6, 8, 8.
These numbers are already in order, so now we find the median. The median is the number in the exact middle of the set. The number in the middle of the set is 5, so that is the median.

Write the log equation as an exponential equation. You do not need to solve for x:
log(x^2+5x-18)=x+2
Answer: 10ˣ⁺² = x² + 5x - 18
Step-by-step explanation: The base of the log becomes the base of the power, the right side of the equation becomes the exponent, and the result in the original equation moves to the other side.

Find the surface area of a cone with volume 320pi and height 15 (hint: don't use the height in
the surface area formula.
Answer key :
Either 200 pi or 325 pi
Please help !!!
Answer:
200π
Step-by-step explanation:
Surface area of a cone = πr(r+l)
r is the radius
l is the slant height
Volume of the cone = 1/3πr²h
320π = 1/3πr²h
320 = 1/3r²(15)
320 = 5r²
r² = 320/5
r² = 64
r = 8
l² = 15² + 8²
l² = 225 + 64
l² = 289
l = 17
Get the surface area;
S = πr(r+l)
S = π8(8+17)
S = π*8*25
S = 200π
Hence the surface area of the cone is 200π
2x+3y=15
X+y=6
Simultaneously equations
Answer:
Step-by-step explanation:
Let's solve your system by substitution.
2x+3y=15;x+y=6
Rewrite equations:
x+y=6;2x+3y=15
Step: Solvex+y=6for x:
x+y=6
x+y+−y=6+−y(Add -y to both sides)
x=−y+6
Step: Substitute−y+6forxin2x+3y=15:
2x+3y=15
2(−y+6)+3y=15
y+12=15(Simplify both sides of the equation)
y+12+−12=15+−12(Add -12 to both sides)
y=3
Step: Substitute3foryinx=−y+6:
x=−y+6
x=−3+6
x=3(Simplify both sides of the equation)
Answer:
x=3 and y=3
Answer:
x = 3, y = 3
Step-by-step explanation:
Given the 2 equations
2x + 3y = 15 → (1)
x + y = 6 → (2)
Multiplying 2) by - 2 and adding to (1) will eliminate x
- 2x - 2y = - 6 → (3)
Add (1) and (3) term by term to eliminate x
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
2x + 3(3) = 15
2x + 9 = 15 ( subtract 9 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
