Tamara rewrote the expression 0.2(4+1.4y -2.1). Her steps are shown.
Step 1: 0.2(4+1.4-2.1)
Step 2: 4.2+1.6 - 1.9
Step 3: 4.2-1.9+1.6y
Step 4: 2.3+1.67
Which statement identifies and explains the first mistake Tamara made?
Her first mistake was in Step 2. She added 0.2 to each term instead of multiplying by 0.2.
Her first mistake was in Step 2. She should have only added 0.2 to 4 instead of adding 0.2 to all 3 terms.
© Her first mistake was in Step 3. When reordering the terms, the 1.6y should be negative and the 1.9 should be
positive.
Her first mistake was in Step 3. When reordering the terms, 1.9 should be the coefficient of y rather than 1.6.

Among the most famous of all meteor showers are the perseids, which occur each year in early august. in some areas the frequency of visible perseids can be as high as 40 per hour. given that such sightings are poisson events, calculate the probability that an observer who has just seen a meteor will have to wait at least five minutes before seeing another.
