The forces acting on a child sitting in a seat are described by the free-body diagram shown. A free body diagram with 2 force vectors. The first vector is pointing downward, labeled F Subscript g Baseline = negative 100 N. The second vector is pointing upward, labeled F Subscript N Baseline = 100 N. The vectors are the same length. What is the net force acting on the child? –100 N 0 N 100 N 200 N.

Heights of men on a baseball team have a bell-shaped distribution with a mean of 177 cm and a standard deviation of 6 cm. using the empirical rule, what is the approximate percentage of the men between the following values? a. 159 cm and 195 cm b. 165 cm and 189 cm a. 89% of the men are between 159 cm and 195 cm. (round to one decimal place as needed.) b. 89% of the men are between 165 cm and 189 cm. (round to one decimal place as needed.)

Given: m∠apc = 27°, m dc = 27° find: m ab
