The heights of 15-year-old American boys, in inches, are normally distributed with mean and standard deviation I select a simple random sample of four 15-year-old American boys and measure their heights. The four heights, in inches, are 63 69 62 66 12. Based on these data, a 99% confidence interval for , in inches, is a. 65.00 1.55. b. 65.00 2.35. c. 65.00 3.09. d. 65.00 4.07.

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

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).

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
