Explanation Approach: The bell-shaped normal curve is symmetric with respect to its mean (denoted as μ ). Thus, 50% of the data values lies to the left of mean and remaining 50% of the data lies to the right of the mean. In a standard bell-shaped normal curve, the weightage of data near the mean is high. Figure 1 Calculation: The z -score corresponding to mean is 0. The positive z-score lies to the right of the mean and the negative z-score lies to the left of the mean. The bell-shaped curve indicates that a greater number of data lie near the mean. Figure 2 illustrates the area under the normal curve between z = 1.3 and z = 2.0 . Figure 2 Figure 3 illustrates the area under the normal curve between z = 0 and z = 0

(3) (4 points) Given three vectors a, b, and c, suppose: |bx c = 2 |a|=√√8 • The angle between a and b xc is 0 = 135º. . Calculate the volume a (bxc) of the parallelepiped spanned by the three vectors.

Calculate these limits. If the limit is ∞ or -∞, write infinity or-infinity. If the limit does not exist, write DNE: Hint: Remember the first thing you check when you are looking at a limit of a quotient is the limit value of the denominator. 1. If the denominator does not go to 0, you should be able to right down the answer immediately. 2. If the denominator goes to 0, but the numerator does not, you will have to check the sign (±) of the quotient, from both sides if the limit is not one-sided. 3. If both the numerator and the denominator go to 0, you have to do the algebraic trick of rationalizing. So, group your limits into these three forms and work with them one group at a time.
