Answer:

Step-by-step explanation:

Remark

There are a couple of things you should keep in mind.

1. Your coefficient should always be a number between 1 and 9.999...

2. If you move right, you have a negative exponent. If you move left, you get a positive exponent.

Solution

So you are going right. The exponent is minus. You have 2 places to go to get a number between 1 and 9.99999. In this case, the coefficient is 3.55 So it goes in the blue box.

The red box is - 2

The answer is: blue 3.55

Orange: -2

Five is three more than a number n. <br> I don't understand this at all!

So what they are telling you is that 5 is three higher than the variable n.
So n = 5-3
so n is 2.

Evan randomly selects 30 marbles from a bag. His data is given in the table.

Igoryamba

The probability of selecting a yellow marble is #of yellow marbles/total # of marbles= 6/30 or .2 or 20%

If there are 300 marbles in the bag, a good estimate for the total number of red marbles in the bag is 90.

9/30=.3 = the percentage of red marbles
.3(300) = 90

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.
