The answer is 0.664 because you have to divide 4/5 and 5/6
Answer:
37.24
Step-by-step explanation:
ok so there's a strategy I got taught ready?
100%- 96.
38%-x
~cross multiply~
100x= 3724
÷100 ÷100
________________
x=37.24
Hope this helps :D p.s- i recommend using this strategy :D
Answer:
a) Sample co-variance = -1.5
b) Sample correlation = -0.4404152
c) Weak negative relationship between X and Y.
Step-by-step explanation:
a) by sample co-variance = sum ((x - xbar)* (y-ybar)/n-1
#.... use the following program in R
x = c(7,8, 5, 3, 9)
y = c(7,5,9,7,7)
sv = sum((x-mean(x))*(y-mean(y)))/4
cor(x,y)

Answer:
solution = (1.-2)
Step-by-step explanation:
put x= 1 and y = -2 in this system : y=-4x+2 and y + 2x = 0
you have : - 2 = - 4(1)+2 and -2 +2(1)=0
-2=-2 and 0=0 .....right
