Answer: The standard deviation was calculated incorrectly.
Step-by-step explanation:
- The standard deviation measures the dispersion of the data values from the mean value.
It cannot be negative , because it is the square root of the variance .
We add all squared deviations from the data points away from the mean and (then divide it by the number of data values) to evaluate variance.
Since , any squared number cannot give a negative result.
⇒ Standard deviation cannot be negative.
⇒The standard deviation was calculated incorrectly.
Rest other things (given in options) can not be interpreted on the basis of given information.
225 divided by 15 equals 15. It will take you 15 hours to get to the 225th mile marker.
Answer:
<em>n = 6 </em>
Step-by-step explanation:
2.3 ×
= (1 × 10³)(2.3 ×
)
(1 × 10³)(2.3 ×
) = (1)(2.3) × (10³)(
) = 2.3 ×
2.3 ×
= 2.3 ×
⇒ 3 + n = 9 ⇒ <em>n = 6</em>

Answer:
No, these triangles cannot lie on the same line.
