The standard deviation of the mileage for the sample of convertibles is 1.98977 miles.
<h3>What is standard deviation? </h3>
Standard deviation is used to determine how the values in a group differs from the mean of the values in the group. It is a measure of variation.
<h3>What is the standard deviation of the mileage? </h3>
In order to determine the standard deviation, take the following steps:
- Determine the mean of the observation:
(25 + 25 + 24 + 21 + 21 + 21 + 20) / 7 =22.43
- Determine the difference between each value and the mean and then square the result:
(25 - 22.43)² = 6.6049
(25 - 22.43)² = 6.6049
(24 - 22.43)² = 2.4649
(21 - 22.43)² = 2.0449
(21 - 22.43)² = 2.0449
(21 - 22.43)² = 2.0449
(20 - 22.43)² = 5.9049
Sum of squared difference = 27.7143
- Determine the mean of the square differences and then find the square root of the mean:
√27.7143 / 7 = 1.98977

Answer:
The maximum value of P is 34 and the minimum value of P is 0
Step-by-step explanation:
we have the following constraints
----> constraint A
----> constraint B
----> constraint C
----> constraint D
Solve the feasible region by graphing
Using a graphing tool
The vertices of the feasible region are
(0,0),(0,5.33),(2,4),(6,0)
see the attached figure
To find out the maximum and minimum value of the objective function P, substitute the value of x and the value of y for each of the vertices in the objective function P, and then compare the results
we have
For (0,0) ----> 
For (0,5.33) ----> 
For (2,4) ----> 
For (6,0) ----> 
therefore
The maximum value of P is 34 and the minimum value of P is 0
Answer:
7× y=4235
y=4235÷7
y=605
therefore the other number is 605
Answer:
7
Step-by-step explanation:
every o e move you make on x you make 7 on y. (made 2 moves in x and moved 14 on y) so if you moved 21 on y.... 21/7=3 so you move 3 on x so 4+3=7
Answer:
x=4.0036≈4 feet
