solve the equation for X by finding a,b, and c of the quadratic then applying the quadratic formula.
Make all the denominators equal
3/8 = 45/120
2/3 = 80/120
4/5 = 96/120
From least to greatest we have,
3/8, 2/3, 4/5
The square root of -17/16 is 0.257694102 i
Yes, it is reasonable, because the ME is 7.1% and 48% falls within the range of 53.8% to 7.1%.
Calculating the ME:
The sample proportion was 53.8%. This gives us
53.8% +/- 7.1%
Answer:
t = 3/2
Step-by-step explanation:
Instead of randomly guessing values of "t" that will satisfy the equation, you can easily find the correct value by solving the equation in terms of "t". In other words, you can set the equation equal to "t" to find the final answer.
(-2/3)t - 2 = -3 <----- Original equation
(-2/3)t = -1 <----- Add 2 to both sides
t = 3/2 <----- Divide both sides by -2/3
You can check this value by plugging it into "t" and determining whether both sides of the equations will be equal.
(-2/3)t - 2 = -3 <----- Original equation
(-2/3)(3/2) - 2 = -3 <----- Plug 3/2 into "t"
-6/6 - 2 = -3 <----- Multiply -2/3 and 3/2
-1 - 2 = -3 <----- Simplify -6/6
-3 = -3 <----- Subtract
