M = -2 and b = 3
so equation
y = -2x + 3
hope it helps
Using the cross product property on this proportion gives us the following equation:
20 (2x - 9) = 10 (9)
Use the distributive property and multiply
40x - 180 = 90
Add 180 to both sides
40x = 270
Divide 40 from both sides
x = 270/40
Simplify fraction
x = 27/4
This should be your answer. Let me know if you need any clarifications, thanks!
Answer:
A. 0.0625
B. 0.1089
C. 0.81
D. 0.0196
Step-by-step explanation:
The proportion of variance is shared by the two correlated variables is given as the r².
Therefore,
For A. r = 0.25
Proportion of variance is shared by the two correlated variables = 0.25²
= 0.0625
For B. r = 0.33
Proportion of variance is shared by the two correlated variables = 0.33²
= 0.1089
For C. r = 0.90
Proportion of variance is shared by the two correlated variables = 0.90²
= 0.81
For D. r = 0.14
Proportion of variance is shared by the two correlated variables = 0.14²
= 0.0196
This problem is mainly concerned with setting up an equation.
let's add the interest rates times their respective investment amounts:
simplify:
sum of interest:
1780 = (9000+x) 0.10 + x 0.06 + (11000-2x)0.08
solution:
He does not have any invested in the 6%, while he has 9000 invested at 10% and 11,000 invested at 8%
to check:
So this ended up being a trick problem because he does not actually have any invested in the 6% option.
V = sqrt 64h
H = 76
V = sqrt * 64(76)
Answer: V = 69.74 ft/sec
