Solution Steps

Step 1: Identify the bounds and parameters

The problem asks for the area under the standard normal curve between _x_ = -0.45 and _x_ = 2.11. The standard normal curve has a mean (μ) of 0 and a standard deviation (σ) of 1.

Step 2: Calculate the area using the cumulative distribution function (CDF)

We can use the normalcdf function on a calculator with the given parameters.

normalcdf(lower bound, upper bound, mean, standard deviation) normalcdf(-0.45, 2.11, 0, 1)

This gives us the area under the curve between the specified bounds.

Step 3: Result of calculation

normalcdf(-0.45, 2.11, 0, 1) ≈ 0.6562

Final Answer: The final answer is $\boxed{d}$

Determine which form of a line the given equation is in. Then, determine the slope, the x-intercept, and the y-intercept. Select the answer choice that correctly identifies each of these. 5x-2y=5 It is in slope-intercept form; the slope is m=-2, the x-intercept is (1,0), and the y-intercept is (0,5). It is in standard form; the slope is m=-2, the x-intercept is (1,0), and the y-intercept is (0, 5/2). It is in standard form; the slope is m=5/2, the x-intercept is (1,0), and the y-intercept is (0,-5/2). It is in point-slope form; the slope is m=5/2, the x-intercept is (1,0), and the y-intercept is (0,-5/2).
