Inventory for a manufacturer are produced at three different plants, 45% from plant 1, 30% from plant 2, and 25% from plant 3. In addition, each plant produces at different levels of quality. Plant 1 produces 2% defectives, plant 2 produces 5% defectives, and plant 3 produces 8% defectives. A. What is the probability that an item is defective?
B. If an item from the inventory is found to be defective, what is the probability that is was produced in plant 2?

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.
