Hello!!

So when we have 2x = 10 we are looking for what x equals. This means you'll want to eliminate what you can to get your answer. What you do on one side must be done on the other. Let's give that a go, sha'll we?

2x = 10

We need to use the inverse operation to eliminate a factor. Since 2x is 2 times x we'll have to divide it.

2x/2 = 10

2 divided by 2 cancels each other out and leaves us with the following;

x = 10

So, x = 10

I hope I helped!!

2x=10
Divide both sides by 2 so x=5 (Because 10 divided by 2 is 5 and 2x turns into just x)

Using a confidence interval of proportions, it is found that the correct statement is given by:

D a confidence interval for estimating the cricket's true probability of landing on its feet is more narrow after the final 10 jumps than it was before the final 10 jumps.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which:

  • \pi is the sample proportion.
  • z is the critical value.
  • n is the sample size.

The margin of error is given by:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

The margin of error is inversely proportional to the square root of the sample size, hence, the higher the sample size, the narrower the interval is, hence option D is correct.
