How would 5/9 be classified? 1. Rational and real. (:

A rational number is any number that can be written as a ratio or a fraction.

So 5/9 is  a rational number. So basically that eliminates 2, 3, and 4.

And we are left with 1. as our answer choice which is Rational and real.

Prove that there are no solutions in integers x and y to the equation 2x^2 + 5y^2 = 14
iren [92.7K]
Solve the equation for y using the formula for slope: y + mx + b

2x^2 + 5y^2 = 14
5y^2 = -2x^2 + 14
y^2 = -2/5x^2 + 14/5
y = the sq root of -2x^2/5 + 14/5

There is no integer solution to the square root of a negative number.

What is the only way to increase power of a significance test when lowering the probability of committing a Type I error
Reil [10]

the probability of making a Type I error is equal to the significance level of power. To increase the probability of a Type I error, increase the significance level. Changing the sample size has no effect on the probability of a Type I error.

The electricity of a take a look at can be expanded in a number of methods, for example increasing the pattern length, reducing the standard errors, increasing the difference between the pattern statistic and the hypothesized parameter, or growing the alpha degree.

The chance of creating a kind I mistakes is α, that's the extent of importance you put for your hypothesis check. An α of 0.05 indicates which you are inclined to accept a five% chance which you are incorrect whilst you reject the null hypothesis. To lower this risk, you have to use a decrease cost for α
