Hello there!
How do you find the y-intercept?
Answer: To find the y-intercept, substitute in 0 for x and solve for y
y = x² + 3x + 5
y = (0)² + 3(0) + 5
y = 0 + 0 + 5
y = 5
Thus, the correct answer is option D (0,5)
I really hope this answer is clear enough for you to understand. If you have questions about the answer, please let me know.
As always, I'm glad to be your helper this evening~!
You don't even have to look up the definition of 'standard deviation'. You only
have to remember that 'smaller standard deviation' means 'less spread-out'.
First, let's find the mean (average). It's not supposed to change:
1/7th of (65 + 71 + 77 + 80 + 82 + 90 + 96) = 561/7 = <u>80 and 1/7</u> .
Now, just pick 7 scores that total 561 and are all bunched up.
The easiest way would be 80, 80, 80, 80, 80, 80, 81 .
But that's so easy that it feels like cheating.
Let's say <u>77, 78, 79, 80, 81, 82, and 84</u> .
