Answer:
69 bpm
Step-by-step explanation:
Here we start out finding the z-score corresponding to the bottom 33% of the area under the standard normal curve. Using the invNorm( function on a basic TI-83 Plus calculator, I found that the z-score associated with the upper end of the bottom 33% is -0.43073.
Next we use the formula for z score to determine the x value representing this woman's heart rate:
x - mean x - 75 bpm
z = ----------------- = -0.43073 = --------------------
std. dev. 15
Thus, x - 75 = -0.43073(15) = -6.461, so x = 75 - 6.6461, or approx. 68.54, or (to the nearest integer), approx 69 bpm
Answer:
the ending balance is $531.51
Step-by-step explanation:
The computation of the ending balance is shown below:
= Opening balance + all deposits - all withdrawls
= $500 + $100 + $250 + $300 - $400.32 - $100 - $55.55 - $62.62
= $531.51
hence, the ending balance is $531.51
