Water consumption by the residents in a local community is normally distributed, with a mean of 340 gallons per day. Ninety-five percent of the residents use between 200 and 480 gallons per day. What is the standard deviation of water consumption in the population in gallons per day? Group of answer choices 70 140 35 280 Flag question: Question 5

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

What is the distance between a and b? round your answer to the nearest tenth. a coordinate plane is shown. point a is located at negative 1, 5, and point b is located at 4, 1. a line segment connects the two points.
