Cotθ= tan30° find theta
scoundrel [369]

Answer:

60

Step-by-step explanation:

Cot is the same as 1/tan so:

1/tan(theta) = tan(30)

By rearranging the equation, we get:

1/tan(30) = tan(theta)

By taking the inverse tan, we get:

theta = tan^-1 (1/tan(30)) =60

hichkok12 [17]

Answer:

b. We are 95% confident that the population mean duration is between 6.9 and 8.2 days.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

95% confidence interval of 6.9 to 8.2 days for the mean expected duration of typical cold.

This means that we are 95% sure that the true duration of a typical cold(population mean) for all health adults in Georgia is between 6.9 and 8.2, which means that the correct answer is given by option b.
