Answer:
   No
Step-by-step explanation:
A probability is a unitless value between 0 and 1, inclusive. 9.48 cannot be a probability (too big). 0.4 acres cannot be a probability (has units).
 
        
             
        
        
        
10. Answer is 9 . (51 - 6) / ( 3.5+5.5) 
11. 5x-18 - 4x = -36
x -18 = -36
x = -18
Answer is -18

Answer:    y = x+1</h3>
===================================================
Explanation:
f(x) = x^3 - 2x + 3
f ' (x) = 3x^2 - 2 ..... apply the power rule
f ' (1) = 3(1)^2 - 2 ... plug in x coordinate of given point
f ' (1) = 1
If x = 1 is plugged into the derivative function, then we get the output 1. This means the slope of the tangent line at (1,2) is m = 1. It's just a coincidence that the x input value is the same as the slope m value. 
Now apply point slope form to find the equation of the tangent line
y - y1 = m(x - x1)
y - 2 = 1(x - 1)
y - 2 = x - 1
y = x - 1 + 2
y = x + 1   is the equation of the tangent line.
The graph is shown below. I used GeoGebra to make the graph.

Answer:
Step-by-step explanation:
let    pickle bought by alexa =x
then according to given condition ,
pickle bought by Tom= (1/3) of Alexa
pickle bought by Tom= (1/3) x
hence also given 
totall pickle cost = Tom cost + alexa cost = 56p
(1/3)x+x=56
taking L.C.M
(4/3)x=56
x=56*3/4
x=42 p
so it means,
<h2>
Alexa cost = x = 42p</h2><h2>
Tom cost = (1/3)x= (1/3)*42 = 14 p</h2>
