But if you're adding them the answer would be $1/ x^{2}y^2$

x^0 y^-3 / x^2 y^-1
= 1 / x^2 y^-1 (y^3) ...because x^0 = 1 and [(y^-1) (y^3)] = y^2
= 1/(x^2 y^2)

Answer:

t = 25.05761543°

Step-by-step explanation:

sin (x) = 36/85 = 0.423529412

sin (x) = 0.423529412

x = sin^-1(0.423529412)

x = 25.05761543°

You intend to estimate a population mean with a confidence interval. You believe the population to have a normal distribution. Y

Luda [366]

Answer:

T = 4.541

Step-by-step explanation:

We don't have the standard deviation for the population, so we use the t-distribution.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 4 - 1 = 3

98% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 3 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.98}{2} = 0.99$ . So we have T = 4.541
