Answer:
Mars
Step-by-step explanation:
100,000,000 kilometers, write a proportion Nadia could use to create her model on the grid paper. Use the proportion to find the distance for each planet on the model.
Using the Empirical Rule, the interval that contains 68% of the scores is [81.5, 90.5].
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
68% of the scores are within 1 standard deviation of the mean, hence the bounds of the interval are:

DE + EF = 4x+2
DE = x+7
EF = 7
Substitute these in
x + 7 + 7 = 4x + 2
x + 14 = 4x + 2
subtract x from both sides
14 = 3x + 2
subtract 2 from both sides
3x = 12
divide both sides by 3
x = 4
substitute this in to find the length of DE
DE = x + 7
(4) + 7 = 11
the answer is 11
Answer:
You would write it as 3 * 10^6
Step-by-step explanation:
To figure this out, look at the decimal place: you got a huge number. 3,000,000. that's the decimal place, right at the far right side. Move the decimal place until you got a number less than 10, so until the number is 3. How ever many times you had to move the decimal place (in this case six times) is the number you put as the power. So the expression is:
3 * 10^6
To find the percent of increase take the difference of the two divided by the original. (62-55)/55 = .12727272727. So 13% if they want you to round to the nearest percent.
