Answer:
68%
Step-by-step explanation:
<em><u>68-95-99.7% Rule:</u></em>
<em><u /></em>
This is the empirical rule which is used to remember the percentage of values that is within a band of the mean. We say:
- 68% of the data fall within 1 standard deviation of the mean
- 95% of the data fall within 2 standard deviation of the mean, and
- 99.7% of data falls within 3 standard deviations of the mean
Clearly, from the empirical rule, we see that about 68% of the area is between z = -1 and z = 1 (or within 1 standard deviation of the mean)
To find volume, multiply length x width x height.
4 1/2 x 5 x 3 1/4
4.5 x 5 x 3.25 = 73.125
1/4 = 0.25
Divide the total of the large cube to the small cube.
73.125/0.25 = 292.5
292 and 1/2 of the small cube(s) are needed to fill the right rectangular prism.

Hey there! The answer is $40000
<span>A car was sold at $34000. That price was 85℅ of the orginal price.
When we know 85% of the original price we can find 1% of this price by dividing by 85.
1% of the original price = $34000 / 85 = $400
</span>When we know 1% of the original price we can find 100% of this price by multiplying by 100.
100% of the original price = original price = $400 * 100 = $40000
The answer is $40000

Answer:
1 is a
2 is c
3 is d
4 is b
Step-by-step explanation:
1. Starting number is 10. Eating 2 pieces per day (x = # of days) is negative
2. To owe someone is negative so the starting number is -10. Then giving $2 per week (x= # of weeks) is positive
3. 10 is below zero so it means negative. The temp drops (negative) 2 per hour (x = hours)
4. Starting on page 10 is positive. Reading 2 pages adds 2 every minute ( x = number of minutes)
