Answer:
A. 120 cubic meters
Step-by-step explanation:
Measurements in volume use <em>cubic</em><em> </em>units which deals with 3 dimensions
The SAT math score has the shape of a standard bell curve or normal distribution. This is because the median and the mean has the same value, therefore, the data is centered and distribute around the mean. The farther we go from the mean, the less probable is to find data with those values.
Now, considering that we have established that the data has a normal distribution, we can use the empirical rule to predict how many percent of the SAT math score data should lie between a 353 and 689. We calculate how many standard deviatioms the maximum and minimum value of the range are from the mean:
This would mean that we need to calculate the percentage of the SAT math score data that would lie within 2 standard deviations from the mean. The empirical rule says that in a normal distribution 68.27% of the data will lie within 1 standard deviations from the mean, 95% will lie within 2 standard deviations and 99.7 will lie within 3 standard deviations. Having calculated that our range is 2 standard deviations from the mean, then 95% of the students will get a SAT math score between 353 and 689.
In summary, the SAT math score has a normal distribution or standard bell shape, and 95% of the SAT math scores will be between 353 and 689, or 2 standard deviations from the mean.
Answer:
The answer is D) 60
Step-by-step explanation:
1st, you have to pick two whole ordered pair points
2nd, you have to use the formula: <u>Y2 - Y1</u>
X2 - X1
3rd, if it has to be simplified, then simplify
4th, you have an answer...
I found two whole ordered pairs which are (2,120) & (4,240).
- 2 represents X1
- 120 represents Y1
- 4 represents X2
- 240 represents Y2
<u>Y2 - Y1</u>
X2 - X1
<u>240 -120</u>
4 - 2
= <u>120</u>
2
Simplify... Divide both 120 &2 by 2 to get this: <u>60</u>
1
= 60
