One the temp is going dropping which sets up for a negative number resulting in -3 degrees
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.
Answer:
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex ad a is a multiplier
Here (h, k ) = (8, - 1 ) , then
y = a(x - 8)² - 1
To find a substitute (0, - 17 ) into the equation
- 17 = a(0 - 8)² - 1 ( add 1 to both sides )
- 16 = 64a ( divide both sides by 64 )
= a , that is
a = -
y = - (x - 8)² - 1 ← equation of parabola
Answer:
Shown Below
Step-by-step explanation:
Alright so first off we are going to use the little 67 on that corner. We know that it's a supplementary angle, and supplementary angles add up to 180.
180 - 67 = 113.
Inside angles of a triangle all add up to 180. Using that we can create the equation:
(x + 27) + x + 113 = 180
simplify.
2x + 140 = 180
subtract 140 on both sides.
2x = 40
divide both sides by 2
x = 20
substitute x into the asked equation.
(20 + 27) = 47
47 is your answer.
Answer:
-0.5
Step-by-step explanation:
Average rate of a function f(x) in the interval a to b is given by
Average rate of change =
Here we are given a graph. From the graph we find out f value at end points
a=0: f(0) = 2: b=2:f(2) = 1
Substitute in the average rate of change formula to get
f(2)-f(0) =1-2 =-1
b-a = 2
Hence average rate of change = -1/2
=-0.5
(Negative value indicates the change is decrease. i.e. when x increases f decreases)
