Answer:

First solve for x

then substitute

Step-by-step explanation:

$\frac{x+3}{3}= \frac{y+2}{2}$

$6(\frac{x+3}{3}=\frac{y+2}{2})$

2x + 6 = 3y + 6

2x = 3y

$x = \frac{3y}{2}$

If $\frac{x+3}{3}= \frac{y+2}{2}$ then $\frac{x}{3}$ =

$x = \frac{3y}{2} /3 = \frac{y}3}$

PtichkaEL [24]

Answer:

Step-by-step explanation:

We will list out the numbers which are factors of 12. They include:

1, 2, 3, 4, 6, 12.

We need to get the highest number that has its greatest factor to be 4. It means that 6 and 12 cannot divide it.

To do this, we will write out the multiples of 4. They include:

4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88,92,96.

We will have to choose the highest number which only 4 can divide and 6 and 12 cannot divide.

Since we are looking for the largest, We can try dividing all the numbers by 4, 6, and 12 starting from 96.

We will quickly see that 4 can divide 92 but 6 and 12 cannot.

This gives us 92 as the answer.

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.
