3 quartz of water...............
Answer:

Step-by-step explanation:
-3 is less than 0, so you are going to use
.
Plug in values:

You first find its intercepts: the x intercept is (5/3,0) and the y intercept is (0,5) (just plot those points). Then make the line connecting those 2 points!
The empirical rule for normal distributions states that approximately 68% of the data points lie within the range plus and minus one standard deviation of the mean.
The answer is 68%.
10. When events are independent, the joint probability is the product of the individual probabilities.
... p(senior & female) = p(senior) × p(female) = 0.30 × 0.54 = 0.162 = 16.2%
11. When events are mutually exclusive, the probability of one or another is the sum of the individual probabilities.
... p(soph or frosh) = p(soph) + p(frosh) = 0.28 + 0.26 = 0.54 = 54%
