Answer:
All 600 members of the club are population of this study
Step-by-step explanation:
There is difference in population of study and the samples taken from that population. All the 600 members of the club are actually the population of this study whereas the 50 members taken out of these 600 members are basically the sample of data. In order for us to carry out the surveys easily, we select a sample from the whole population. The sample has smaller number as compared to the whole population making it easier for us to carry out survey.

Step-by-step explanation:
Consider that F(x,y,z) = (x + y, y + z, z + z)

Answer:
there you go
Step-by-step explanation:
The length of a train car is 50.6 feet. This is 5.8 feet less than 6 times the width. What is the width?
l = 50.6
We are also given:
6w - 5.8 = 50.6
Answer:
37.7
Step-by-step explanation:
n - 0.47n = 20
0.53n = 20
n = 37.7
Answer:
undefined
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( -4-4)/( -3 - -3)
= ( -4-4)/( -3+3)
= -8/0
When we divide by zero, the answer is undefined so the slope is undefined
