Answer:

Step-by-step explanation:

Since this is a linear system, there can be 1, 0, or infinite solutions. In order to determine this, we need to solve this equation.

First, isolate the variables to one side:

0 = 97x -97

97x = 97

x = 1.

Thus there is one solution.

If we had gotten a statement such as 1 = 1, there would have been infinite.

If we had gotten a statement such as 1 = 0, there would have been no solution.

Find the critical value necessary to form a confidence interval at the level of confidence shown below.

Rzqust [24]

Answer:

the critical value for 0.87 level of confidence is 1.51

Step-by-step explanation:

Given the data in the question;

level of confidence = 0.87

now,

1 - c = 0.87

c = 1 - 0.87

c = 0.13

c/2 = 0.13/2 = 0.065

now

1 - c/2 = 1 - 0.065 = 0.935

so our level of significance ∝ = 0.935

Now, the critical value will be;

$Z_{0.935$ is obtained as follows;

P( Z < z ) = 0.935

so we find the value from ( standard normal distribution table )

P( Z < 1.51 ) = 0.935

Therefore, the critical value for 0.87 level of confidence is 1.51

X to the third power = 125/27

nika2105 [10]

When raising a fraction to a power, we can raise the numerator and denominator to the power. To find x, we need to find the cube root of both 125 and 27. That is, the numbers that when multiplied by themseelves 3 times result in 125 and 27.

$\sqrt[3]{125} = 5$

$\sqrt[3]{27} =3$

So x = $\frac{5}{3}$
