Answer:
Letter B. Both graphs have been shifted and flipped
Answer:
(a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)
Step-by-step explanation:
Given
(a + b)³ + 8c³ ← this is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²)
Thus
(a + b)³ + 8c³
= (a + b)³ + (2c)³
= (a + b + 2c)( (a + b)² - 2c(a + b) + (2c)² )
= (a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)
<u><em>Answer:</em></u>
Option 3
<u><em>Explanation:</em></u>
<u>To get the value of the cheapest bike, best option, we will calculate the total cost of each bike:</u>
<u>i- Option 1:</u>
Total cost = $88
<u>ii- Option 2:</u>
$5 down payment and $8 per week for 10 weeks
Total cost = 5 + 8(10) = 5 + 80 = $85
<u>iii- Option 3:</u>
$12 down payment and $5 per month for 12 months
Total cost = 12 + 5(12) = 12 + 60 = $72
<u>iv- Option 4:</u>
$20 down payment and $20 per month for 12 months
Total cost = 20 + 20(12) = 20 + 240 = $260
<u>Now, from the above calculations, we can conclude that:</u>
The best price would be that of option 3 ($72). It is the lowest price compared to other option.
Hope this helps :)
Answer:
Step-by-step explanation:
There are three reasons here why randomization is not being applied.
First, the coach is only observing football players attending the meeting. This is not representative of the entire team.
Second, there is no selection process. The coach isn't using a random generator or using a similar method.
Third, the players are volunteering for the test. The results will be biased because of this.
