Answer:
225 seconds
Step-by-step explanation:
First,
1km = 1000 meter
This means,
0.9 km = 900 meter
Second, to find the time taken,
0.25 x 900 = 225
Therefore,
225 seconds
Hope this helps!!

Answer:
a) The probability of selling less than 100 gallons (x≤1) is P=0.16.
b) The mean number of gallons is M=80 gallons.
Step-by-step explanation:
The probability of selling x, in hundred of gallons, on any day during the summer is y(x)=0.32x, in a range for x from [0;2.5].
The probability of selling less than 100 gallons (x≤1) is then:
![P(x\leq1)=\int_0^{100}0.32x\cdot dx\\\\P(x\leq1)=0.16(x_b^2-x_a^2)\\\\P(x\leq1)=0.16(1^2-0^2)=0.16](https://tex.z-dn.net/?f=P%28x%5Cleq1%29%3D%5Cint_0%5E%7B100%7D0.32x%5Ccdot%20dx%5C%5C%5C%5CP%28x%5Cleq1%29%3D0.16%28x_b%5E2-x_a%5E2%29%5C%5C%5C%5CP%28x%5Cleq1%29%3D0.16%281%5E2-0%5E2%29%3D0.16)
The mean number of gallons can be calculated as:
![M=\int_0^{2.5}(y(x)/x)\cdot dx=\int_0^{2.5}(0.32)\cdot dx\\\\M=0.32(x_b-x_a)=0.32(2.5-0)=0.32*2.5=0.8](https://tex.z-dn.net/?f=M%3D%5Cint_0%5E%7B2.5%7D%28y%28x%29%2Fx%29%5Ccdot%20dx%3D%5Cint_0%5E%7B2.5%7D%280.32%29%5Ccdot%20dx%5C%5C%5C%5CM%3D0.32%28x_b-x_a%29%3D0.32%282.5-0%29%3D0.32%2A2.5%3D0.8)
Answer:
The total finance charge you will pay on this cash advance for the month is $60.50.
Step-by-step explanation:
Your bankcard has an APR of 9%.
So, monthly rate =
= 0.75%
p = 2200
Simple interest =
dollars
There is a 2% fee for cash advances.
So, cash fee for $2200 is =
dollars
The total finance charge will be =
dollars
Therefore, the total finance charge you will pay on this cash advance for the month is $60.50.
Answer: 14
Step-by-step explanation:
- Degrees of freedom is the number of values in the evaluation of a test statistic that are free to vary.
For t-statistic , the degree of freedom for a sample with sample size 'n' is given by :-
![df=n-1](https://tex.z-dn.net/?f=df%3Dn-1)
Given : Sample size : n-1
Then, the number of degrees of freedom the t-value will have :-
![df=15-1=14](https://tex.z-dn.net/?f=df%3D15-1%3D14)
Hence, the t-value will have 14 degrees of freedom.
