Answer: Gonzo runs 0.435 seconds faster than Kermit.
Step-by-step explanation:
This is just a simple subtraction problem.
To make both numbers even in place value, add a 0 (zero) in the back of 12.35 to make it 12.350.
Then you simply subtract using regrouping methods:
12.350
11.915 -
————
0.435
Now let’s check our answer:
11.915
0.435. +
—————
12.35
As a result, Gonzo ran 0.435 seconds faster than Kermit.
The answer elevation /_angle B /_ V
For simple interest rate,
I=P(i)t
54=900(i)(18/12)
i=54/900*(12/18)=4% annually
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.
