Three dentists wanted to compare the ages of their patients. they each calculated their patients’ mean age and the mean absolute deviation of their ages. they displayed the results in a table. which statements are true? select each correct answer. dr. cantwell’s patients’ ages and dr. singh’s patients’ ages vary about the same amount. dr. singh’s patients’ ages and dr. appiah’s patients’ ages vary about the same amount. dr. appiah’s patients’ ages vary less than do dr. singh’s patients’ ages. dr. appiah’s patients’ ages vary more than do dr. cantwell’s patients’ ages. dentist mean patient age mad appiah 43 9.7 cantwell 29 13.9 singh 41 14.1

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
