The Given Sequence is an Arithmetic Sequence with First term = -19
⇒ a = -19
Second term is -13
We know that Common difference is Difference of second term and first term.
⇒ Common Difference (d) = -13 + 19 = 6
We know that Sum of n terms is given by : 
Given n = 63 and we found a = -19 and d = 6
The Sum of First 63 terms is 10521
I was able to find the image associated with this question, in which the coordinates of point Z are given as (-2,-1).
We know that the coordinates of a point are multiplied by the scale factor to give the new coordinates. Since these coordinates result after the dilation, we divide them by the scale factor to obtain the original coordinates as such:
-2/0.25 , -1/0.25
(-8 , -4)
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
The expression 120+4x represents the cost of producing x items. The selling price is $5 for each item.
<u>The net income formula:</u>
y= (5 - 4)x - 120
(5-4)= contribution margin per unit sold (x)
120= fixed costs
<u>To calculate the break-even point in units, we need to use the following formula:</u>
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 120 / 1
Break-even point in units= 120 units
Prove:
y= 1*120 - 120
y= 0
You ended without giving the values, so we can't get the exact answer. However, I can tell you steps.
First, you need to find the z-score. Then, look up the z-score on a normal distribution table and you will get the percent.
Let's call your value X. Just plug X into the equation below and you will have your z-score.
(x - 20.5) / 3.5 = z
Now, look up the z-score and you will have your probability.<span />
Answer: $380.75x0.075=28.55625
28.55625+380.75=409.30625
$409.30625~$409.31
Answer: $409.31
