Answer:
122
Step-by-step explanation:
<HEB=180-(42+32)
=180-74
=106
<DEA=180-106 (straight line)
=74
<NAD=48+74(exterior angle = sum of 2 interior opposite angles)
<NAD=122
The approximate solution you require is the x coordinate of the point of intersection of the 2 graphs.
Answers:
- Discount price = 280.50 dollars
- Amount lost = 49.50 dollars
================================================
Explanation:
If it's sold at a loss of 15%, then the store owner loses 0.15*330 = 49.50 dollars
So it was sold for 330- 49.50 = 280.50 dollars
----------------------------
An alternative method:
If the store owner loses 15%, then they keep the remaining 85% since 15%+85% = 100%.
85% of 330 = 280.50 dollars is the discount price
This means 330-280.50 = 49.50 dollars is the amount lost.
Answer:
Commutative Property of Addition
Step-by-step explanation:
a+b=b+a
Basically we have to calculate P X < 0.95. By using the normal distribution formula for any random variable we can get our answer.
SO first from z table we will have to check the corresponding z value from the table. After we get that value we can do X - mean / the std dev = that particular value that i am naming A.
SO X - 5 / 0.5 = A. Now we can solve X for our answer.
