The answer is C 3. she has a 50/50 chance of grabbing either black or white. Subtracting either a black or white sock, the probably of getting a matching pair is 1/3 from there.
Answer:
what is the complete question?
Answer:
Applied the definition and the limit.
They had the same result, so the function is continuous.
Step-by-step explanation:
At function f(x) is continuous at x = a if:
In this question:
At x = 3.
Since 
, f(x) is continuous at x = 3.
Answer:
a. positive.
Step-by-step explanation:
Matching and discordant pairs are used to describe the relationship between pairs of observations. To calculate matched and discordant pairs, data is treated as ordinal values. Therefore these are suitable for your application. The number of concordant and discordant pairs is used in Kendall's tau calculations, whose purpose is to determine the relationship among two ordinal variables.
If the direction of the classifications is the same, the pairs are concordant.
A pair of observations is discordant, suppose the subject being with an increased value on one variable is lower on the other.
SO; When discordant pairs exceed concordant pairs in a P-Q relationship, Kendall's tau reports a(n) <u>positive</u> association between the variables under study.
This is a parabola which opens upwards
y - (-3) = sqrt ((y+1)^2 + (x + 5)^2
(y + 3)^2 = y^2 + 2y + 1 + (x + 5)^2
y^2 + 6y + 9 = y^2 + 2y + 1 + (x + 5)^2
(x + 5)^2 = 4y + 8
(x + 5)^2 = 4(y + 2)
Its C
