Im no expert but i think its
input: x,independent variable ,domain
output: y, dependent variable , range
extra: f(x) , discrete, and slope
Answer:
B -0.104
Step-by-step explanation:
Step 1: Write the formula for correlation
r = total xy
√Total x² x Total y²
Step 2: Make a table to calculate all values
Table is attached in the picture below
Step 3 : Solve
Mean of X = Total X/ Total number of X
= 507/12
= 106.33
Mean of Y = Total Y/ Total number of Y
= 1276/ 12
= 42.25
r = total xy
√Total x² x Total y²
r = -352.05/ √3656.25 x 3122.66698
r = -0.104
-0.104 is negative
This negative correlation means there is an inverse correlation between variables.
Hi there!
Use th' following formula
To find the distance between each pair of pts. :-
According to th' question :-
♦ (-2, -2) (-2, 10) :--
=
= 12
Therefore,
distance between the following pts. is 12 units.
♦ (-5.3, -2.2) (-5.3, -8.7) :--
=
= 6.5
Therefore,
distance between th' following pts. is 6.5 units.
~ Hope it helps!

Answer:
d) 1998 to 2000
Step-by-step explanation:
Consumer price index (CPI) is an economic indicator that shows the average change in prices of items, goods and services. Basically, if CPI is increasing over a period of time that means that there is inflation, and if it decreases that means that there is deflation (lowering of prices).
Now, looking at our table, we see that:
- 1992-1994: CPI increased from 44.3 to 58.2 -> inflation
- 1994-1996: CPI increased from 58.2 to 65.9 -> inflation
- 1996-1998: CPI increased from 65.9 to 70.4 -> inflation
- 1998-2000: CPI decreased from 70.4 to 69.1 -> deflation
