Answer:
This can be solved by using the empirical rule for a normal distribution.
Step-by-step explanation:
A. The number of skateboards given is one standard deviation above the mean. Approximately 68% of the data points lie within the range plus and minus one standard deviation of the mean. Therefore the required percentage is:
68 + 16 = 84%.
B. The given number of skateboards is two standard deviations above the mean. Approximately 95% of the data points lie within the range plus and minus two standard deviations of the mean. Therefore the required percentage is:
5/2 = 2.5%
C.The given number of skateboards is one standard deviations below the mean. Therefore the required percentage is:
16%.
Answer:
1
Step-by-step explanation:
You'd use the equation a^2 + b^2 = c^2 (**** ^2 means squared****)
a = 60
b = 11
c = ?
60^2 + 11^2 = c^2
3600 + 121 = c^2
3721 = c^2
then just square root 3721 and c^2
c = 61 feet
the degree of the polynomial is 8
The degree of a polynomial is determined by the largest power of an individual term or the sum of the exponents if more than 1 variable
3x² → is degree 2
6xy → is degree 2 ( sum of 1 and 1 )
- 10
→ is degree 5
→ is degree 6
- 10x³
→ is degree 8 ( sum of 3 and 5 )
the term with largest power is - 10x³
The degree of the polynomial is 8
