Alocal grocery store sells individually packaged slices of cake, all labeled with the same weight of 4 oz. suppose we take a random sample of 49 cake slices and record their weights. the mean weight of our sample of 49 slices is 4.2 oz. assume that the population standard deviation is 0.2 oz true or false? it is very likely that the actual cake slice weight mean is higher than 4 oz a. true b. false

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
