Let x represent the scores. With mean and standard deviation given,

The Empirical rule states that

1) About 68% of the x values lie between 1 standard deviation below and above the mean

2) About 95% of the x values lie between 2 standard deviation below and above the mean

3) About 99.7% of the x values lie between 3 standard deviation below and above the mean

If we consider this rule, then the percentage of scores that fall within 3 standard deviation (-3 to +3) is 99% because this is closer to 99.7%

Answer:

The answer is 0.24.

Step-by-step explanation:

Hey there!

This question asks us to find products of two numbers given a table.

As we can see, we can find the product of each number if we separate them by whole integers and their decimal counterparts.

For instance, if we want to find the product of 0.8 and 1 using this table, we would find the cell that meets where 0.8 and 1 are together.

We see that the cell where 0.8 and 1 meet is 0.8, which is the product of the two values.

Therefore, if we want to find the value of the question mark, we just need to find the product of 0.8 and 0.3.

0.8 \times 0.3 = \boxed{0.24}

Therefore, the value for the question mark is 0.24.

What single decimal multiplier would you use to increase by 4% followed by a 3% increase
Mandarinka [93]

Answer:

1.0712

Step-by-step explanation:

if you increase by 4%, it means you will have a new total of 104%. In decimals it is 1.04 (divide your percentage by 100) after that you do the same with the 3% increase. you'll have a new total of 103%. In decimals 1.03. If you want to know what single multiplier you can use, you need to multiply the both decimals. So you get 1.04 x 1.03 = 1.0712

hope this will help you, have a nice day!
