Answer:
2a² + 2b²
Step-by-step explanation:
(a - b)² + (a + b)² ← expand both factors using FOIL
= a² - 2ab + b² + a² + 2ab + b² ← collect like terms
= 2a² + 2b²
If the baseball pitcher won 80% of the games he pitched and he pitched 35 ballgames, and you would like to know how many games did he win, you can calculate this using the following steps:
80% of 35 = 80% * 35 = 80/100 *35 = 28 games
Result: The baseball pitcher won 28 games.
Answer:
10.44
Step-by-step explanation:
The weighted average cost per unit method seeks to get the cost of goods sold as an average of all cost of goods in the inventory as at the time of sales.
Part of its objective is to strike a balance between the (FIFO and LIFO) inventory valuation methods.
Beginning inventory ( Jan) = 10 units
Cost of beginning inventory per unit = $10
Total cost of beginning inventory = Cost * Number of units
In this case (10*$10) = $100
Additional purchase (Jan 5) = 8 units
Cost of additional purchase per unit = $11
Total cost of additional purchase = 8 * $11 = $88
Weighted average cost per unit at the time 11 units are sold on January 7 = Total cost of units at that time / number of units available at that time.
= ($100+ $88) / (10+8)
= 188/18
=10.44 (approximated to 2 decimal places)
I hope this helps make the concept clear.
This is the concept of arithmetic, if you increase your score of 85% by 7%, you will have a score of:
New score=old score+increase
=85+7
=92%
the new score will be 92%
Answer:
- <u>1H, 1T, 2H, 2T, 3H, 3T, 4H, 4T, 5H, 5T, 6H, and 6T.</u>
Explanation:
The quetion is:
- <em>list all the outcomes in the same format </em>
<h2 /><h2>Solution</h2>
Understand the format:
- first character is the number that appears on the top face of the dice: it can be 1, 2, 3, 4, 5, or 6.
- second charater is one of two letters that represent the flip of the coin: H for heads or T for tails.
Then, the list of the combinations that represent all the possible outcomes is:
- 1H, 1T, 2H, 2T, 3H, 3T, 4H, 4T, 5H, 5T, 6H, and 6T.
They are 12 possible outcomes: 6 × 2 = 12: 6 from the 6 possible outmoes of the dice, and 2 for the two possible outcomes of the coin.
