Suppose a teacher assigns an average of 9.3 homework problems per learning target. Find: a) The probability that the teacher assigns 4 homework problems for LT5A. Round your answer to 4 decimal places.

b) The probability that that the teacher assigns 18 homework problems for LT5B. Round your answer to 4 decimal places.

What would be considered a "usual" number of homework problems assigned? Use the definition of usual as μ ± 2⋅ σ

1) neither are usual
2) 4
3) 18
4) both are usual

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
