Answer:
I think A
Step-by-step explanation:
Because 4 can be simplified to 2
and 15 can be simplified into 5
hope it's right don't be mad if it's not
Correlation coeffiencients is used to determine the relationships between data, Correlation coefficients can test two or more variable(s) at a time
<h3 /><h3>What are correlation coefficients?</h3>
This is a linear correlation between sets of data. This coefficient can only be between -1 and 1.
Positive values show a positive correlation while a negative value shows negative correlation. A correlation coefficient of zero shows no relationship between variables.
Based on the explanation, we can conclude that Correlation coefficients can test two or more variable(s) at a time

Answer:
b = 141
Step-by-step explanation:
b − –573 = 714
Subtracting a negative is adding
b + 573 = 714
Subtract 573 from each side
b − 573+573 = 714-573
b =141
Answer:
12
Step-by-step explanation:
for this you need to draw a straight line and plot the points J,K,L,M,N according to the question.
here,
given K lies between J and M, L is between K and M , M is between K and N.
JN= 30, KM=8
JK=KL=LM
MJ= ?
according to the question,
J--------K-------L--------M-------N
KM= 8
KL+LM= 8 (KL+LM=KM)
KL+KL=8 ( given, LM=KL)
2KL= 8
KL=4
so,
JK= KL=4 and LM= KL= 4
now,
MJ= ?
we know
MJ= JK+KM = 4+8= 12
Answer:
D -9
Step-by-step explanation:
(g o f)(-1) = g(f(-1))
f(-1) = 
g(-4) = -4 - 5 = -9
So, (g o f)(-1) = -9
