Step-by-step explanation:
∑k=150(3k+2)
First find a1 and a50 :
a1=3(1)+2=5a20=3(50)+2=152
Then find the sum:
Sk=k(a1 + ak)2S50=50(5 + 152)2=3925
58…
Explanation:
I’m confused, either you worded it wrong, or this is the easiest question ever. The question says “58 of the student are boys. How many students are boys?”
<u>The possible answers are:
</u><u /><u /><u><em /></u>4.21
4.22
4.23
4.24
Explanation:
We want a number between 4 1/5 and 4.25. We will convert 4 1/5 to a decimal first:
Divide 1 by 5: 1/5 = 0.2.
This makes 4 1/5 = 4 + 1/5 = 4 + 0.2 = 4.2.
We want a number between 4.2, which can be written as 4.20, and 4.25. Any number between will do, so the possible answers would be
4.21, 4.22, 4.23, or 4.24.<u />
