We need to find how many students have at least one social media account.
We know that there are 120 students in the class.
We also know that there are 65% of students that have at least one social media account.
To find your answer, would multiply 120 by 0.65:
120 · 0.65 = 78
This means that 78 of the students has at least one social media account.
Answer:
78 students
Answer:
Line of "rise": (0, 3) to (0, 0) ==> -3 units
Line of "run": (0, 0) to (1, 0) ==> 1 unit
Slope: rise/run ==> -3/1
Step-by-step explanation:
Slope is basically a ratio of changes in the y-value to changes in the x-value. What I mean by that is the slope shows how much the line goes up or down compared to how much the line goes left or right. In this case, the line goes right one unit for every 3 units the line goes down. Taking a look at the portion of the line in Quadrant 1 (top right quadrant), the line starts at (0, 3) and ends at (1, 0). I guess that's another way to figure out slope, too: line up the two coordinates (the leftmost one above the rightmost one), and add or subtract.
Like this:
(0, 3)
<u> (1, 0) </u>
+1 -3
Since the formula for slope is rise/run (y-difference/x-difference), the slope is therefore -3/+1, or simply -3/1. (You don't include plus signs.)
7 is incorrect. The answer should be -4. Here's how I'd derive it:
With 
, we should expect 
. If 
, then
Also,
so we should expect 
and
You seem to be taking
but this is not an identity.

8 is incorrect. Just a silly mistake, you swapped the order of the terms in the numerator. It should be

If Danielle wants to buy a car on a loan and she wanted the least possible amount of payment in paying its interest over the loan term, to answer it.. Danielle should pay up a higher amount of principal and she should check the interest rate offered by the loaner. There are different bracketing of interest in loan terms.
