Determine whether the triangles are similar. If they are, list the facts that prove this. Then give the similarity statement and by what condition the triangles are similar. If the triangles are not similar, explain the reason why they are not similar.

The weight of full–grown tomatoes at a farm is modeled by a normal distribution with a standard deviation of 18.4 grams. the 95 percent confidence interval for the mean weight of the tomatoes is calculated using a sample of 100 tomatoes. what is the margin of error (half the width of the confidence interval)?

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?

Given sin28.4=.4756, cos28.4=.8796, and tan28.4=.5407 find the cos of 61.6
