Suppose s varies directly with t. When t27, s=3. What is s when t=632
2 answers:
Answer:
G
Step-by-step explanation:
Given that s varies directly with t then the equation relating them is
s = kt ← k is the constant of variation
To find k use the condition when t = 27, s = 3 , then
3 = 27k ( divide both sides by 27 )
= k, that is
k =
s = t ← equation of variation
When t = 63, then
s = × 63 = 7 → G

Using the Empirical Rule, it is found that:
- a) Approximately 99.7% of the amounts are between $35.26 and $51.88.
- b) Approximately 95% of the amounts are between $38.03 and $49.11.
- c) Approximately 68% of the amounts fall between $40.73 and $46.27.

The Empirical Rule states that, in a <em>bell-shaped </em>distribution:
- 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.
-----------
Item a:
Within <em>3 standard deviations of the mean</em>, thus, approximately 99.7%.
-----------
Item b:
Within 2<em> standard deviations of the mean</em>, thus, approximately 95%.
-----------
Item c:
- 68% is within 1 standard deviation of the mean, so:
Approximately 68% of the amounts fall between $40.73 and $46.27.
