If the average of nine consecutive integers is zero, what is the largest integer?

Orlov [11]

Answer:

Step-by-step explanation:

The average of the consecutive integers is 0, so the middle number must be 0, with 4 numbers less than 0 and 4 numbers greater than 0.

-4, -3, -2, -1, 0, 1, 2, 3, 4

So the largest integer is 4.

disa [49]

Answer:

There is sufficient evidence. A further explanation is provided below.

Step-by-step explanation:

According to the question,

The alternative as well as null hypothesis will be:

$H_0:\mu = 16$

$H_a:\mu>16$

The test statistics will be:

⇒ $z = \frac{\frac{\bar x - \mu}{\sigma} }{\sqrt{n} }$

By putting the values, we get

⇒ $=\frac{\frac{16.06-16}{0.24} }{\sqrt{96} }$

⇒ $=\frac{\frac{0.06}{0.24} }{\sqrt{96} }$

⇒ $=2.45$

Or,

The p-value will be:

= 0.0071

i.e.,

⇒ $p-value< \alpha$

Thus the above is the correct answer.

Help ASAP!!!<br> First to answer with a correct answer gets brain...

Llana [10]

Hey there!

First, let's multiply each side of the equation by 3 to get rid of the fraction $\frac{2}{3}$ .

9 + 2x = $\frac{6}{5}$

Next we can multiply each side of the equation by 5 to get rid of the fraction $\frac{6}{5}$ .

45 + 10x = 6

There's your answer!

Hope this helps!
