Answer:
For a pair of randomly selected in- and out-of-state students, the sum of their tuition typically varies from the mean of $6,348.75 by about $1,508.48.
Step-by-step explanation:
Given
Required
Interpret the standard deviations
In statistic, standard deviation is a measure of how the given data lies away (or varies) from the mean.
This implies that:
For the in-state students, the standard deviation measures how the sum of their tuition varies from 6348.75
For the out-state students, the standard deviation measures how the sum of their tuition varies from 1508
Answer:
In the picture attached, the question is shown.
a) Applying Pythagorean theorem to triangle ABC, and solving for AC:
CB² + BA² = AC²
5² + 12² = AC²
√169 = AC
13 cm = AC
b) Applying Pythagorean theorem to triangle ACD, and solving for AD:
CD² + AC² = AD²
5² + 13² = AD²
√194 = AD
13.9 cm = AD
