Answer:
Step-by-step explanation:
<u>For each odd i the term is:</u>
<u>For each even i the term is:</u>
So the sum of the first 100 terms is zero
Answer: A
Explanation:
Just use substitution because it's more efficient. Plug -2x-8 into y to make -2x-8=3x+2. Add 8 to both sides to get -2x=3x+10. Subtract 3x to both sides to get -5x=10. Divide -5 to both sides to get x=-2. Now, plug in x=-2 to one of the equations, let's use y=3x+2. The equation would be y=3(-2)+2. Multiply 3 and -2 to get -6. Add -6 to 2 and you'll result with y=-4.
Answer:
a) 27. b) 8/3
This is your answer ☺️☺️☺️
Mode: 7, Median: 7, Mean: 5.6
Median:
First, we put it in numerical order:
2, 3, 7, 7, 9
Then we crossed out the two on the sides:
3, 7, 7
Then we do it again...
7
Then we are left with 7! So the median is 7!
Mode:
Mode is most common number in the group of number so the number that appeared two times is 7. So the mode is 7.
Mean:
We add all numbers together:
2+7+3+7+9 =28
Then we divide that number by the number of numbers we have:
28/5 = 5.6.
