Answer:
a) 0.35
b) 420 drawing pins
Step-by-step explanation:
a) The question relates to the relative frequency of the pins pointing up which is found by the formula as follows;
The total number of pins land 'point up' = 3 + 5 + 6 + 2 + 4 + 7 + 3 + 3 + 4 + 5
The total number of pins land 'point up' = 42 successful trials
Total number of trials = 12 × 10 = 120 trials
Due to the large number of trials, the relative frequency ≈ Probability and the probability that a single pin will land point up = 7/20 = 0.35
b) Given that the number of trials now = 12 × 100 = 1200, we have;
The expected number of drawing pins in total that would land point up = 0.35×1200 = 420 pins.

Answer:
1. D) -30
2. B) -33
3. A) 600
Step-by-step explanation:
1. This answer would be D) -30 because the statement is saying that Keith <u><em>lost </em></u> 30 lbs, and losing something would be a negative
2. This answer would be B) -33 because just like in the first question, something is decreasing or falling. In this case, it's the temperature that is falling.
3. This answer would be A) 600 because since Alice is already above the ground 100 feet, all you would do is add the 500 feet that she rose with (100 + 500). To rise would be to increase, or in this rate, stay positive.
