7n-8=-29
You got the equation correct.
I'm not sure if you want me to solve n but I'll do it in case you need help on that.
First, add 8 on both sides which would equal 7n=-21.
Now, divide 7 on both sides.
n=-3
Hope this helps
Answer:
The indifference point is 100 minutes.
Step-by-step explanation:
Giving the following information:
Plan a cost $23 plus an additional $.08 for each minute of calls.
Plan B cost $19 an additional $.12 for each minute of calls.
<u>First, we need to establish the total cost formula for each plan:</u>
Plan A= 23 + 0.08*x
Plan B= 19 + 0.12*x
x= number of minutes
<u>Now, to calculate the indifference point, we equal both formulas and isolate x:</u>
23 + 0.08x = 19 + 0.12x
4 = 0.04x
100= x
The indifference point is 100 minutes.
<u>Prove:</u>
Plan A= 23 + 0.08*100= $31
Plan B= 19 + 0.12*100= $31
It’s basically tell you to bring it down by 10 so it’s (5,-6)
Answer: A. 0.62
Step-by-step explanation:
As all the given r values are positive therefore, there is a positive correlation.
A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
The strongest linear relation is stipulated by a correlation coefficient 'r' of -1 or 1.
The weakest linear relation is stipulated by a correlation coefficient equal to 0.
Thus, the nearest number to 1 , represents the strongest correlation.
Therefore, A. 0.62 is the required answer which represents the strongest correlation. .
