Calcula las operaciones que se indican entre los polinomios si se sabe que: -P (y) = 7y3 + 5y2 - y + 2
-Q (y) = 10y - 5 - 6y4 - 3y2
-Z (y) =20y2 - 15 - 8y4 + 7y
-A) P(y) + Q(y)
-B) Z(y) - P(y)
-C) Z(y) + Q(y)

What two criteria are needed for triangles to be 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)?

The graph shown is the graph of which function?
