C, A, B
A’s rate if change:
3
B’s rate of change:
(10 - 0) / (-2 - (-4)) = 10 / 2
5
C’s rate of change:
1
        
             
        
        
        
Step-by-step explanation:
2(sp)=ln
6x+2=10x-6
8=4x
x=2
therefore sp=3×2+1=6+1=7
Option D
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Let x be the random variable. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula, 
z = (x - µ)/σ
Where
x = sample mean 
µ = population mean 
σ = standard deviation
From the information given,
µ = 474
σ = 32
x = 514
The probability of being below 514 is expressed as P(x < 514)
For x = 514,
z = (514 - 474)/32 = 1.25
Looking at the normal distribution table, the probability value corresponding to area below the z score is 0.89
Therefore, 
P(x < 514) = 0.89
 
        
             
        
        
        
Answer: 3/2
Step-by-step explanation:
Let's consider the points (6,9) and (4,6).
The difference in the y coordinates is 3, and the diffeence in the x coordinates is 2.
So, the slope is 3/2.
