Answer:
n<2
Step-by-step explanation:
6.2n<2n+8.4
Move variable to the left hand side and change its sign
6.2n - 2n < 8.4
Combine like terms
4.2n < 8.4
divide both side by 4.2
n < 2
The given equations are

(1)

(2)
When t=0, obtain

Obtain derivatives of (1) and find x'(0).
x' (t+1) + x - 4√x - 4t*[(1/2)*1/√x = 0
x' (t+1) + x - 4√x -27/√x = 0
When t=0, obtain
x'(0) + x(0) - 4√x(0) = 0
x'(0) + 9 - 4*3 = 0
x'(0) = 3
Here, x' means

.
Obtain the derivative of (2) and find y'(0).
2y' + 4*(3/2)*(√y)*(y') = 3t² + 1
When t=0, obtain
2y'(0) +6√y(0) * y'(0) = 1
2y'(0) = 1
y'(0) = 1/2.
Here, y' means

.
Because

, obtain

Answer:
The slope of the curve at t=0 is 1/6.
Answer:

Step-by-step explanation:
The ratio is simply the division of one by another (and simplification).
Hence, <u>the ratio of production of the first line to the second line</u> is 1250 divided by 2825. So,
Ratio =

Answer:
Mean = 15.83 hours
Median = 17 hours
Step-by-step explanation:
The first step to follow when dealing with data distributions is to arrange the data in either an ascending or descending order.
Once this is done, we have the responses as
responses: 9. 14, 16, 18, 19, 19
The mean of the distribution can be obtained by dividing the total sum of the values, by the number of respondents.
this is 
The mean of the distribution is 15.83 hours
The median is obtained by picking out the middle number of the distribution. However, our distribution is even, and hence has two middle numbers. To solve this , we simply add the two numbers and divide by 2
= (16 + 18 )/2 = 34/2 = 17
