X+y=1 show work and graph it please. and use x/y.

Answers

Answer 1

Answer: you will put x=0 and calculate the value of y=1 and then put y=0 and get value of x=1 and then put x=1 and get value of y=0 and then put y=1 and get x and so one , finally you could plot the graph.

determine whether the given first-order differential equation is linear in the indicated dependent variable by matching it with the differential equation given in (7) in section 1.1, a1(x) dy dx a0(x)y

Answers

The given first-order differential equation is linear in the indicated dependent variable because it matches the standard form of a linear first-order differential equation, a1(x) dy/dx + a0(x)y = f(x).

First, let us review what a linear first-order differential equation is. Ais a differential equation that can be written in the form:

a1(x) dy/dx + a0(x)y = f(x)

Now, let us compare the given differential equation to the standard form of a linear first-order differential equation. The given differential equation is:

a1(x) dy/dx + a0(x)y

As we can see, the given differential equation matches the standard form of a linear first-order differential equation. Therefore, we can conclude that the given differential equation is linear in the indicated dependent variable.

In conclusion, the given first-order differential equation is linear in the indicated dependent variable because it matches the standard form of a linear first-order differential equation, a1(x) dy/dx + a0(x)y = f(x).

08.01)Marlow wants to know how many students in his school enjoy watching the TV news. He asks all 27 students in his art class and finds that 30% of his classmates enjoy watching the TV news. He claims that 30% of the school's student population would be expected to enjoy watching the TV news. Is Marlow making a valid inference about his population?No, it is not a valid inference because he asked all 27 students in his art class instead of taking a sample from the school

No, it is not a valid inference because his classmates do not make up a random sample of the students in the school

Yes, it is a valid inference because he asked all 27 students in his art class

Part 1 : Marlow wants to know how many students in his school enjoy watching the TV news. He asks all 27 students in his art class and finds that 30% of his classmates enjoy watching the TV news. He claims that 30% of the school's student population would be expected to enjoy watching the TV news. Is Marlow making a valid inference about his population?

No, it is not a valid inference because he asked all 27 students in his art class instead of taking a sample from the school

No, it is not a valid inference because his classmates do not make up a random sample of the students in the school

Yes, it is a valid inference because he asked all 27 students in his art class

Yes, it is a valid inference because his classmates make up a random sample of the students in the school

Answer = The correct answer is B because Marlow was supposed to ask random kids and they were not suppose to be in his class.

Part 2 : Carl takes a random sample of 100 students in his school and finds that 72% of the sample prefers pizza over burgers. There are 1,500 students in the school. Based on the sample proportion, how many students in the school would be expected to prefer pizza over burgers?
