Answer:
(b) It means that the results that Tessa obtained are too unusual to be explained by chance alone
Step-by-step explanation:
The test for statistical significance is a comparison of the result to the probability that it occurred by chance. The probability of a chance occurrence is usually set at 1% or 5%. The lower the percentage, the less likely a chance occurrence is, and the more difficult showing statistical significance becomes.
Urban Dictionary says yeet is "especially used in basketball when someone has shot a three-pointer that they are sure will go in the hoop". This is probably a derivation from the dance, during which the dancer calls out "yeet" when making a throwing action with their arms.
Step-by-step explanation:
let's simply do the multiplications and then compare with the original.
(x-m)² + n
right ?
or is it
![{(x - m)}^{2 + n}](https://tex.z-dn.net/?f=%20%7B%28x%20-%20m%29%7D%5E%7B2%20%2B%20n%7D%20)
let's go for the first.
x² - 2mx + m² + n = x² - 3x
-2mx + m² + n = -3x
fun there we see two things :
-2m = -3
m = 3/2
and
m² + n = 0
(3/2)² = -n
9/4 = -n
n = -9/4
so our transformed expression looks like
(x - 3/2)² - 9/4
Answer:
Last choice is correct.
