The heights of 175 randomly selected adult female, and those heights have a standard deviation of 15.55 cm. Because it is reasonable to assume that heights of female statistics
students have less variation than heights of the population of adult females, o = 15.55 cm. How many female statistics students must be measured in order to estimate the mean height of all female statistics students? Assume that we want a 99% confidence that the sample mean is
within 3.5 cm of the population mean.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

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)
