Answer:

not a linear equation

Step-by-step explanation:

its a quadratic equation bcz whenever the power of variable exceeds 1 it is not a linear equation then. even if we plot a graph by assuming values of x we will see a curve is forming hence not a linear equation

Consider the null hypothesis, H0: µ = 4,000, at the 1% level of significance. If the z-test statistic is calculated to be 6.00,

kow [346]

Answer:

Option B) Reject null hypothesis

Step-by-step explanation:

We are given the following in the question:

We are given the null hypothesis:

$H_0 = 4,000$

$\alpha = 0.01$

$z_{stat} = 6.00$

Two tailed z-test

Now, $z_{critical} \text{ at 0.01 level of significance } = \pm 2.58$

Since,

The calculated z-statistic does not lie in the acceptance region, we fail to accept and reject the null hypothesis.

Left-tailed z-test

Now, $z_{critical} \text{ at 0.01 level of significance } = -2.58$

Since,

$z_{stat} > z_{critical}$

We fail to accept and reject the null hypothesis.

Right-tailed z-test

Now, $z_{critical} \text{ at 0.01 level of significance } = 2.58$

Since,

$z_{stat} > z_{critical}$

We fail to accept and reject the null hypothesis.

Solve the equation. check your solution. 2/9g=-8

SCORPION-xisa [38]

g=-36

Solving the equation:

(2/9)g=-8

(9/2)(2/9)g=-8(9/2)

g=-4(9)

g=-36

vlabodo [156]

The greatest common factor of 4ab and 8a^3 is 4a.

Your answer is C.

That is because the highest number you can divide 4ab and 8a^3 by is 4a.

Solve the inequality -4n > 36

Lemur [1.5K]

Answer:

n < -9

Step-by-step explanation:

Divide both sides by -4, like so:

-4n > 36

n > -9

However, anytime you multiply/divide the inequality by a negative number, you must flip the sign around, like so:

n < -9
