50 points has to be a new answer NOT from any sites.
a) Describe how the line of best fit and the correlation coefficient can be used to determine the correlation between the two variables on your graph.
Answer:
A correlation coefficient shows where one variable changes in results to the other. A line of best fit is the best fit line that passes through or near the graphed data. It is used to describe data and predict where new data will appear on the graph. These two methods help to find correlation between variables as they are used to predict how and where variable are and will go in correlation to one another.

A red light flashes every 6 seconds.
A yellow light flashes every 4 seconds.
They both flash at the same time.
After how many seconds will they next both flash at the same time?
Answer:
Red light flashes once every 6 seconds, blue light flashes once every 10 seconds, so the next time the blue light flashes(20 seconds), the red light would have completed 18 seconds and the next time blue light flashes (30 seconds), the red light would also be flashed at the same time.

Answer:
x = 9 degrees
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp side/ hypotenuse
sin x = 15/91
Taking the inverse sin of each side
sin ^-1 (sin (x)) = sin ^ -1( 15/91)
x =9.487658996
To the nearest degree
x = 9 degrees

Step 1: Define Systems
2x + y = 5
3x - 2y = 4
Step 2: Rewrite Systems
Manipulate 1st equation
[Subtraction Property of Equality] Subtract 2x on both sides: y = 5 - 2xStep 3: Solve for x
Substitution
Substitute in y [2nd Equation]: 3x - 2(5 - 2x) = 4[Distributive Property] Distribute -2: 3x - 10 + 4x = 4[Addition] Combine like terms: 7x - 10 = 4[Addition Property of Equality] Add 10 on both sides: 7x = 14[Division Property of Equality] Divide 7 on both sides: x = 2Step 4: Solve for y

A train travels a distance of 120 km at a constant speed of V kmh 1. If the speed
is reduced by 10kmh), then the time taken to the journey is increased by one
hour. Find the constant speed V of train.
Help me Please
Answer:
The speed of the train is 40 km/h.
Step-by-step explanation:
Since a train travels a distance of 120 km at a constant speed of V km / h, and if the speed is reduced by 10km / h, then the time taken to the journey is increased by one hour, to find the constant speed V of the train, the following calculations must be performed:
20 x 6 = 120
10 x 7 = 140
30 x 4 = 120
20 x 5 = 100
40 x 3 = 120
30 x 4 = 120
Therefore, the speed of the train is 40 km/h.

Determine if the columns of the matrix form a linearly independent set. Justify your answer. Choose the correct answer below. A. The columns of the matrix do form a linearly independent set because the set contains more vectors than there are entries in each vector. B. The columns of the matrix do form a linearly independent set because there are more entries in each vector than there are vectors in the set. C. The columns of the matrix do not form a linearly independent set because the set contains more vectors than there are entries in each vector. D. The columns of the matrix do not form a linearly independent set because there are more entries in each vector than there are vectors in the set.
Th matrix is missing. The matrix is :
[tex]\begin{bmatrix}1 &-4 &4 \\ -4 &16 & 4 \end{bmatrix}[/tex]
Solution :
The column of the matrix are [tex]\begin{bmatrix}1\\ -4\end{bmatrix}[/tex] , [tex]\begin{bmatrix}-4\\ 16\end{bmatrix}[/tex], [tex]\begin{bmatrix}4\\ 4\end{bmatrix}[/tex]
Now each of them are vectors in [tex]$IR^2$[/tex]. But [tex]$IR^2$[/tex] has dimensions of 2. But there are 3 column vectors, hence they are linearly dependent.
Therefore, the column of the given matrix does not form the [tex]\text{linearly independent set}[/tex] as the set contains [tex]\text{more vectors}[/tex] than there are entries in each vector.
Therefore, option (D) is correct.

CD is the Diameter. The measure of Arc CD is llx Find the length of the radius in the circle
Answer:
11
Step-by-st1p explanation:
34.5575191895
so circumference for semi circle is 34.56
times that by two u get circumference for circle
which is 69.12
formula for circle =
C=D*pi
so D=C/pi
so D=69.12/pi
approximately = 22
and divide that by 2 to find radius

Amelia needs to buy some cat food. At the nearest store, 2 bags of cat food cost $4.50. How much would Amelia spend on 6 bags of cat food?
Answer:
$13.50
Step-by-step explanation:
2 bags of cat food = $4.50
1 bag of cat food = 2/4.50
= 2.25
6 bags of cat food = 2.25*6
=13.50
solve the system of equations using elimanation
-2x+2y=6
4x+2y=-5
Answer:
Your solution is (-11/6, 7/6).
Step-by-step explanation:
-2x + 2y = 6
4x + 2y = -5
Right away I can see that our y-values are the same. We want to eliminate one variable at a time, so let's make one of the 2y's a positive by multiplying each term in the equation by -1.
4x + 2y = -5
-1(4x + 2y = -5)
-4x - 2y = 5
Now we have a new equation in our system.
-2x + 2y = 6
-4x - 2y = 5
Now eliminate by performing each action given by the terms.
-2x + 2y = 6
-4x - 2y = 5
_________
-6x = 11
Divide both sides by -6.
x = 11/-6
Now that we know x, plug it back into one of the original equations to find y.
-2x + 2y = 6
-2(11/-6) + 2y = 6
Multiply.
-22/-6 + 2y = 6
22/6 + 2y = 6
Subtract 22/6 from both sides.
2y = 6 - 22/6
2y = 36/6 - 22/6
2y = 14/6
2y = 7/3
Divide both sides by 2.
y = (7/3)/2
y = 7/6
Your solution is (-11/6, 7/6).
Check your answer by plugging both values into one of the original equations.
4x + 2y = -5
4(-11/6) + 2(7/6) = -5
Multiply.
-44/6 + 14/6 = -5
Add.
-30/6 = -5
Divide.
-5 = -5
Your answer is correct.

Writes a number sentence that is an example of the Distributive Property of Multiplication. Which shows Jamie's number sentence? Group of answer choices
Answer:
The answer is "[tex]8\times 9=70+2[/tex]"
Explanation:
The distributive property indicates that by simply multiplying integers (factors) together, each factor would be split into 2 accompanying texts, both added by the other and that both products would be added together. Its distributive property explains that How we break down one of the components doesn't matter.
[tex]\to 8\times 9=70+2\\\\\to 72=72[/tex]
So, L.H.S=R.H.S
Product of two integers is -6 and There sum is 1
Answer:
3 and -2
Step-by-step explanation:
xy = -6
x + y = 1
let 'x' = y-1
y(y-1) = -6
y² - y + 6 = 0
(y-3)(y+2) = 0
y = 3 and -2
