Answer:
Step-by-step explanation:
observe
It's 1,000,000:
<span>the sum is 1 + 3 + 5 + ... 1999999 </span>
<span>= 1 + 2 + ... + 2000000 - 2*(1 + ... + 1000000) </span>
<span>= 2000000*2000001/2 - 2*(1000000*1000001 / 2) </span>
<span>= 1000000*(2000001 - 1000001) = 1000000000000 (one million million) </span>
<span>and dividing this by one million to get the average, </span>
<span>you get one million</span>
Answer:
7 + 8i
Step-by-step explanation:
Conjugate of 7 - 8i is 7 + 8i
First, get the sum of the ratio. (11 + 2 = 13)
Divide 52 by 13 to find one 'part' of the ratio. (52 ÷ 13 = 4)
Now that we have one 'part' of the ratio, we multiply it by 11 and 2 to get: (£4 × 11 = £44) and (£4 × 2 = £8).
The ratio will be £44:8.
We can check if this is correct by adding 44 and 8 to see if it adds up to 52. (44 + 8 = 52). It does, so it's correct.
