You need to multiply 57100 by 0.07 = 3997
and then add 3997+57100 = $61,097
Answer: 7
Step-by-step explanation:
denotes the intersection of A and C, or in other words, how many elements are shared between them.
The number of elements is 2 + 5 = 7
TR ( total revenue ) = P ( price ) x Q ( quantity ) = ( 50 - 5 x² ) · x
TR = 50 x - 5 x³
Profit = TR - TC ( total cost ) = 50 x - 5 x³ - 30 x = - 5 x³ + 20 x
If x = 1 ( 1 million hoops ):
15 = - 5 · 1³ + 20 · 1 = - 5 + 20
If we want to find another production that makes the same profit:
15 = - 5 x³ + 20 x
5 x³ - 20 x + 15 = 0 / : 5
x³ - 4 x + 3 = 0
( x - 1 ) ( x² + x - 3 ) = 0
x ≈

Answer:
0.3
Step-by-step explanation:
The margin of error is calculated as ...
(standard deviation)/√(sample size) × (z*-score)
where the z*-score is chosen based on the desired confidence level.
Here, you have ...
- standard deviation = 2.7
- √(sample size) = √225 = 15
- z*-score for 90% confidence level = 1.645
Putting these values in the above expression for margin of error gives ...
2.7/15·1.645 = 0.2961 ≈ 0.3
Two right angles is 90+90=180°. the inside angles of a polygon always add up to 360°, so the other four angles add to 360°-180°=180°. 180/4 is 45. since all of the "x" angles are the same, x=45°
