According to a study conducted by a university, children who are injured seven or more times tend to sustain these injuries during a relatively limited time, usually 1 year or less. Let the average number of injuries per year for school-age children be seven.

(a) Calculate the mean and standard deviation for x, the number of injuries per year sustained by a school-age child. (Round your answers to three decimal places.) 𝜇=  injuries 𝜎=  injuries

(b) According to Tchebysheff's Theorem, within what limits would you expect the number of injuries per year to fall at least three-quarters of the time? (Round your answer up to the nearest whole number.) 1  injury to   injuries

The increased number of small commuter planes in major airports has heightened concern over air safety. An eastern airport has recorded a monthly average of nine near misses on landings and takeoffs in the past 5 years. (Round your answers to three decimal places.)

(a) Find the probability that during a given month there are no near misses on landings and takeoffs at the airport . 

(b) Find the probability that during a given month there are three near misses.

(c) Find the probability that there are at least three near misses during a particular month.

Yes, that's correct! Calculus is a branch of mathematics that deals with the study of rates of change and the accumulation of small amounts of change. The two main areas of calculus are differential calculus and integral calculus, as you mentioned.

Differential calculus deals with the study of rates of change and slopes of curves. It is concerned with the calculation of derivatives, which are a measure of how a function changes at a given point. Derivatives are used to study the behavior of functions, to find the maximum or minimum values of functions, and to solve optimization problems in various fields such as physics, engineering, economics, and more.

Integral calculus, on the other hand, deals with the accumulation of small changes and the calculation of areas and volumes. It is concerned with the calculation of integrals, which are used to find the area under a curve or the volume of a solid. Integrals are also used to solve problems in physics, engineering, economics, and other fields.

Together, differential and integral calculus form the foundation of modern mathematics and are essential tools in many scientific and engineering disciplines.

A mixture of BaCl₂ and Na₂CO₃ in to be analyzed for its barium chloride content by the Volhard method. The following data are given. The AgNO₃ threat solution is prepared by dissolving 4.933 g of silver metal of 99.10% purity in nitric acid and diluting with water to exactly 500 ml in a volumetric flask. In the standardization of the KSCN solution, it is found that a volume of 25.00 ml of the AgNO₃ solution requires 22.00 ml of the KSCN solution. A 0.5000 g sample is dissolved, acidified, and a volume of 40.30 ml of AgNO₃ solution is added: the excess of silver is then back-titrated, requiring 6.22 ml of the KSCN solution.

(a) Calculate the normality of the silver (107.87) solution.

(b) Calculate the normality of KSCN solution.

A careless fisherman accidentally spilled an entire 20-oz bottle of soda into Lake Michigan. The soda contained 101.8 mg of caffeine (c8h10n4o2) per 20 oz bottle. What is the resulting molar concentration of caffeine in the lake? Assume that the lake receives no additional caffeine other than from this one bottle of soda; you may also assume that the caffeine is evenly distributed throughout the lake.

Useful facts about Lake Michigan:

Surface area= 5.80 x 10^4 km^2

Average depth = 279 ft

Average water density = 1.0 g/mL
