Answer:
The ratio would be 1:2 my guy,if you're trying to triple the size, 1:3 if your trying to quadruple the size, it'd be 1:4, etc, etc
We can use a system of equations to solve this.
Notice that we are required to find 3 consecutive even integers.
This can be represented as x, y, and z, where x is the smallest integer, y is the next largest, and z is the largest of the three.
x = x
y = x + 2
z = y + 2
Take a moment to make sense of the above system of equations.
I can simplify the system a bit more by plugging in the second equation into the third one.
z = (x + 2) + 2
z = x + 4
Now the new system of equations is
x = x
y = x + 2
z = x + 2
Now for the second part of this problem. We are given this equation
2x + z = 268216
You may notice that we no longer need the second equation, y = x + 2. Also, the first equation is redundant, so we can ignore it.
That leaves us with this system:
z = x + 4
2x + z = 268216
What do you think we should do? We can plug in z to solve for x.
2x + (x + 4) = 268216
3x + 4 = 268216
3x = 268212
x = 89404
Now we know the first number in the sequence! Then we can find the other two numbers, because we know that the next numbers must be the next largest even numbers in sequence!
89404, 89406, and 89408 are your answers.
The mistake he made was that he multiplied 2 and 3, equaling 6. But what he SHOULD have done was multiply 2 * 2 * 2 to get 8
Answer:
a. There are 12 observations from the resulting data set.
b. This is an analytic study. It compares the flow rates through a solenoid valve based on three factors at four different levels.
Step-by-step explanation:
Observations of the dependence of flow rate
Factors Armature Spring Bobbin
Lengths Load Depth
Levels
Low 1 1 1
Moderate 1 1 1
High 1 1 1
Extreme 1 1 1
Total observations 4 4 4
Number of observations = 12
b) Whereas enumerative studies are statistical studies carried out to draw a conclusion on a process or a condition, analytic studies are statistical studies that compare two or more groups or sets of data to improve future performance. The focus of an analytic study is on the process rather than the condition. Enumerative studies tend to explain, evaluate, and describe the condition of the dataset.
