Use a graphing calculator to solve the equation 3 tan 1/3x=8 in the interval from 0 to 2π round your answers to the nearest hundredth.

Use a graphing calculator to solve the equation  

3 tan 1/3x =8  

In the interval from 0 to 2pie Round your answers to the nearest hundredth.

Given equation is

To graph this equation we write the given equation as

y= 3 tan(\frac{1}{3} x) - 8

The graph is attached below

From the graph the value of x  is 3.636

When round to two decimal place, the value of x = 3.64

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

246
