NegativePositiveStrong Positive======================================================
Explanation:
We'll focus on the plot at the very left. The dots seem randomly scattered about, but they seem to go downhill as we move from left to right. I would consider this fairly weak negative correlation since the points aren't anywhere close to the same single straight line (known as the regression line or line of best fit), but again they seem to trend downhill in some fashion. Since "weak negative" isn't an answer choice, I'd go with "negative".
---------------------------------
Now move to the scatterplot in the middle. We have the points trending upward as we move from left to right. I'd consider this weak positive correlation for similar reasoning as discussed in the previous section. Since "weak positive" isn't listed, I would go with "positive" as the next best thing.
---------------------------------
Lastly, the third plot has similar properties to the second one. Though the points are now more clumped together around where the regression line would go. You can think of the regression line as a magnet that is pulling in the points. We don't have a perfect positive correlation, or else all the points would lay on the same line and there wouldn't be any straggler/outlier points that are off the line. I would consider this to be strong positive correlation.
Unfortunately the distinction between "strong positive" and "very strong positive" is too vague. Your teacher hasn't defined where the cutoff line is between each. I'm going with "strong" over "very strong" because the points seem to have a bit more wiggle room to get closer to the line, yet still not be considered perfectly on the line. Again this is all subjective and will be a matter of opinion. Without a ruleset and hard numbers, it's impossible to answer this accurately. The same can be said about the previous two sections, but I don't think there's as much ambiguity there.
solve 15-y>8 show working
Answer:
y <7
Step-by-step explanation:
15-y>8
Subtract 15 from each side
15-15-y>8-15
-y>-7
Multiply each side by -1, remembering to flip the inequality
-1 * -y > -7*-7
y <7
Can someone help me answer these two questions
Answer:
C) 7=y=5x+11
B) m=-4/5, b=13/5
Step-by-step explanation:
Problem 1:
A function is linear if its slope is constant and/or its graph is straight (that means 1-degree polynomials only). Therefore, C is the only correct answer.
Problem 2:
Convert to slope-intercept form (y=mx+b):
4x+5y=13
5y=13-4x
y=13/5-4/5x
y=-4/5x+13/5
Now we can see that since the original equation is in slope-intercept form (y=mx+b), the slope, m, is -4/5, and the y-intercept, b, is 13/5, making option B the correct answer.
Determine the volume of the cylinder. Round to the nearest tenth in necessary
7.5in is the radius and 11in is the height.
Step-by-step explanation:
volume of cylinder πr2h
radius = 7.5in
height = 11in
volume= 22/7 x7.5 x7.5x11
= 1942.875
therefore volume =1942.875 in

The expression that has a term with a coefficient of 6 is бу.
Option A is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The term "coefficient" refers to the numerical factor that is multiplied by a variable or variables in a term.
Out of the given expressions, only one has a term with a coefficient of 6, which is:
6y
Thus,
The expression that has a term with a coefficient of 6 is бу.

Each month Marla pays a $30 cell phone bill from her bank account. At the
end of one year, what is the change in the amount of money in Marla's account
because of her cell phone bill? Write a multiplication equation to represent the
problem. Explain what the product represents.
Answer:
-$360.00 change
Step-by-step explanation:
Now there is either some information missing, like her starting total in the bank; or they want you to explain the net change. But the way the question is worded it is stating she is paying $30 over 12 months. This means she has paid $360.00 in that 12 months aka 1 year. Her bank account should have had a balance. So you could technically say B for balance. B-30*12. To get your answer. Although there are many ways to write an equation expression of this question. If you know the starting balance then it's better. But you could assume her starting balance was $0. Which would be 0-30M*12 where M could represent monthly. And the same answer would occur of 360. Is there more information?
30*12= X (x equals the total paid)
X-30*12 (if x is her balance before paying any money)
