Answer:
The answer is A
Step-by-step explanation:
z=0.80
Answer:
0.3175
Step-by-step explanation:
z=-1.25 from table is .1056
z=.80 from table is .7881
subtract from each other =.6825
Subtract from the whole is 1-.6825=0.3175
In the given function, by first determining the value of the constant b, we are then able to substitute x = -2 into the function to find that f(-2) = -5.
In this problem, we are given the function f(x) = 3/2x + b and we know that f(6) = 7. This allows us to determine the value of the constant b by substituting these values into the function and solving for b:
7 = 3/2*6 + b --> 7 = 9 + b --> b = -2.
Now that we have the value of b, we can find f(-2) by substitifying x = -2 into the function: f(-2) = 3/2*-2 + (-2) = -3 -2 = -5. So, the value of f(-2) is -5.
