Answer: The answer is A
Step-by-step explanation: You use normalcdf to find the area under a curve. The lower bound (in this case 7) goes first followed by the upper bound, mean, and standard deviation.
To evaluate this expression, we simply plug the value of the variable into the expression and solve.
Since m = -4, plug a -4 in for m every time the m appears in the expression.
So we have (-4)^2 + 6(-4) + 3.
Start by simplifying the exponent.
(-4)^2 is 16.
Now multiply.
A positive times a negative is a negative.
So 6(-4) is -24.
So we have 16 + 24 + 3 which is 43.
