Part 1): 10³
Part 2): Ten cubed or
ten to the power of 3.
<u>Explanation </u>
Part 1
Figures written in exponent form means they should be in indices. That means they should be in power form.
10×10×10 = 10³.
Part 2
10³ ⇒ Ten raised to power 3. This can be written as ten cubed.

Are you familiar with z-scores? According to the definition,
(given numerical value) - (mean)
z = ---------------------------------------------
standard deviation
Thus, with the given numerical value equal to 410 and the std. dev. equal to 75, the corresponding z-score is
410-500 -90
z = --------------------- = --------------- = -1.2
75 75
Use a table of z-scores to determine the area under the standard normal curve to the left of z = -1.2. Your result is the probability that a given family chosen at random spends less than $410 per month.
