Answer:
12
Step-by-step explanation:
5^2 + b^2 = 13^2
25 + b^2 = 169
169-25= 144
take the square root of 144
answer: 12
The answer b
Because the first two logs are being add together and that means you multiply the 3 and 11 together to get 33.
And when they have a 2 in front of the long that means you square it the the number behind the log in this case 5^2
Therefore you're answer would have to be b. Log2(33*5^2)
Answer:
70 fish
Step-by-step explanation:
Answer:
a) 88.89%
b) 84%
c) 75%
Step-by-step explanation:
We are given the following in the question:
Average price = $3.06 per gallon
Standard deviation = $0.06 per gallon
Chebyshev's Rule:
- According to this rule atleast percent of data lies within k standard deviation of mean.
a) minimum percentage of gasoline stations had prices within 3 standard deviations of the mean
We put k = 3
Thus, minimum 88.89% of gasoline stations had prices within 3 standard deviations of the mean.
b) percentage of gasoline stations had prices within 2.5 standard deviations of the mean
We put k = 2.5
Thus, minimum 84% of gasoline stations had prices within 2.5 standard deviations of the mean.
Range of gasoline price:
c) minimum percentage of gasoline stations that had prices between $2.94 and $3.18
We can express $2.94 and $3.18 as:
We put k = 2
Thus, minimum 75% of gasoline stations had prices between $2.94 and $3.18.
