Answer:
s > 6
Step-by-step explanation:
1st step: subtract 3 from each side of the inequality to get:
2s > 12
2nd step: divide each side by 2 to get:
s > 6
Answer:
a.) Minimum test score = 41
Maximum test score = 95
b.)An approximate value of the standard deviation is 9.
Step-by-step explanation:
The given set of test scores is approximately bell shaped.
The mean of the test scores, = 68
The range of the data set = 54.
a.) i.) Minimum test score =
ii.) The maximum test score =
b.) From the 68-95-99.7 rule, also known as the Empirical rule, tell us that an approximation of the range is 3 standard deviations either way from the mean. So from this rule we can say that the minimum can also be found from and the maximum can also be approximated as .
From the above we can say that the range can be written as
∴
∴
Therefore an approximate value of the standard deviation is 9.
Answer:
f(1/a) = 1/a² + 2/a + 1
Step-by-step explanation:
Step 1: Define
f(x) = x² + 2x + 1
f(1/a) is x = 1/a
Step 2: Substitute and Evaluate
f(1/a) = (1/a)² + 2(1/a) + 1
f(1/a) = 1/a² + 2/a + 1
