Last Wednesday, two friends met up after school to read the book they were both assigned in Literature class. Adam can read 1 page per minute, and he had already read 79 pages. Cody, who has a reading speed of 4 pages per minute, had read 49 pages. Eventually they had read the same number of pages. How long did that take? How many pages had each of them read?

1. if we have 3 babies what is the probability they’re going to be all boys? 2. if we roll 2 die at the same time what is the probability of getting less than 10 on the first roll and a 5 on the second roll 3. if we have 3 babies what is the probability their is going to be 2 girls? 4. if we have 3 babies what is the probability of having no more than 1 girl? 5. it we have 3 babies and then have another 3 babies what is the probability of us having at least 1 boy and then having all girls?

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?

Cody was 165cm tall on the first day of school this year, which was 10% taller than he was on the first day of school last year.
