# Mr. Svenson devised a training technique for goalkeepers at his soccer academy. He believes that if goalkeepers train using this technique, they will improve their goal-saving rate in games. The goal-saving rate is the ratio of the number of saves made by a keeper to the number of opposition shots that were on target. To test how effective his new training technique is, Mr. Svenson splits the goalkeepers at the academy into two groups. One group trains using traditional methods, and the other group trains using the new technique. Mr. Svenson compares the goal-saving rates of keepers from the two groups in games played against the same level of competition. He finds that keepers who trained using his new technique had a higher goal-saving rate than those who used traditional methods. What does the goal-saving rate of keepers represent in this case? ОА. the response group ОВ. the explanatory variable O c. the response variable OD the control group

Answer from: Quest

The equation is .Differentiating with respect to x, we have , that is .This means that Differentiating again, using the quotient rule for the right hand side expression:

Answer from: Quest

114 plus 113 times 2 and 114 times 3

Answer from: Quest

We have to solve the equationIn order to solve it for x, subtract 3/x to both sidesMultiply both sides by LCMOn simplifying, we getTo check the extraneous solution, we plugging this value of x in the given equation and check if it satisfies or notThis is true. Hence, x=12 is a solution (non-extraneous) to the given equation.A is the correct option.

Cylinder: First you need to find the radius. To do that, you need to divide the diameter by 2 Then, you multiply it by itself After that, you multiply it by the height And finally multiply it by piCone: First, you need to find the radius dividing the diameter by 2Then, multiply it by itself After that, divide the height by 3 Finally, multiply the radius times the height and then multiply it by pi The answer to the cylinder is 251.2 and the answer to the cone is 251.2The processes are the following:CylinderD:8R:4V:π4^2*5V:π16*5V:80πV:251.2ConeD:8R:4V:π4^2 15/3V:π16*5V:80πV:251.2
