You go to school in a college town. You know that there are 2000 students enrolled in the school, but you don’t know the population of the town (without students). You walk up and down the main streets of the town, stop people, and ask them if they are students or not. You ask 100 people, and 60 of them say they are students. Estimate the nonstudent population of the town.

Answers

Answer 1
Answer: 2,000/100=20
40*6=240
I hope got it correct
240 non students
:)

If ln y = (ln x)2 + 2, then find dy / dx in terms of x and y.

Answers

Answer:  The required value of(dy)/(dx) is(y)/(1-y).

Step-by-step explanation:   We are given to find the value of(dy)/(dx) from the following equation :

\ln y=(\ln x)^2+2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

Differentiating both sides of equation (i) with respect to x, we have

(d)/(dx)\ln y=(d)/(dx)((\ln x)^2+2)\n\n\n\Rightarrow (1)/(y)(dy)/(dx)=(d)/(dx)(\ln x)^2+(d)/(dx)2\n\n\n\Rightarrow (1)/(y)(dy)/(dx)=2\ln x*(d)/(dx)\ln x+0\n\n\n\Rightarrow (1)/(y)(dy)/(dx)=2(\ln x)/(x)\n\n\n\Rightarrow (dy)/(dx)=(2y\ln x)/(x).

Thus, the required value of(dy)/(dx) in terms of x and y is (2y\ln x)/(x)..

The answer is 5.87x10^14 this is because when you multiply 5870000000000 times 100 you get 5.87x10^14

use the function rule, y=2x +5, to find the values of y when x=1,2,3,and 4. write the answers as ordered pairs that would be used to graph the function please show work

Answers

y = 2x + 5

x = 1

Replace x with 1, and evaluate the right side.

y = 2 * 1 + 5 = 2 + 5 = 7

Ordered pair: (1, 7)

x = 2

Replace x with 2, and evaluate the right side.

y = 2 * 2 + 5 = 4 + 5 = 9

Ordered pair: (2, 9)

x = 3

Replace x with 3, and evaluate the right side.

y = 2 * 3 + 5 = 6 + 5 = 11

Ordered pair: (3, 11)

x = 4

Replace x with 4, and evaluate the right side.

y = 2 * 4 + 5 = 8 + 5 = 13

Ordered pair: (4, 13)

The 4 ordered pairs are: (1, 7), (2, 9), (3, 11), (4, 13)

y = 2(1) + 5
y=2+5=7. (1,7)

2(3) + 5
y=6+5= 11. (3,11)

2(2) + 5
y=4+5=9. (2,9)

2(4) + 5
y=8+5=13. (4,13)

The number of times a player has golfed in one's lifetime is compared to the number of strokes it takes the player to complete 18 holes. The correlation coefficient relating the two variables is -0.26. Which best describes the strength of the correlation and what is true about the causation between the variables?

Answers

Answer: It is a weak negative correlation and it is not likely causal.

Step-by-step explanation:

Given: The number of times a player has golfed in one's lifetime is compared to the number of strokes it takes the player to complete 18 holes. The correlation coefficient relating the two variables is -0.26.

Variables : "number of times a player has golfed in one's lifetime" and "number of strokes it takes the player to complete 18 holes".

Since -0.26 is more closer to 0 as compared to 1 , so it describes a weak negative correlation.

Also, it is not likely causal as number of times a player has golfed in one's lifetime not cause number of strokes it takes the player to complete 18 holes.

Answer: B) It is a weak negative correlation, and it is likely casual
