What is the approximate area of the shaded region under the standard normal curve below? Use the portion of the standard normal table given to help answer the question. A normal curve with a peak at 0 is shown. The area under the curve shaded is negative 2 to negative 1. z Probability 0.00 0.5000 1.00 0.8413 2.00 0.9772 3.00 0.9987

13.59%

Step-by-step explanation:

The z score is a measure used in statistic to determine by how much standard deviations the raw score is above or below the mean. If the raw score is greater than the mean then the z score is positive but if the raw score is less than the mean then the z score is negative. The z score is calculated using:

From the normal distribution table, Area between z equal -2 and z equal -1  = P(-2 < z < -1) = P(z < -2) - P(z < -1) = 0.1587 - 0.0228 = 0.1359 = 13.59%

step-by-step explanation:

it's 15

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
