A company did a survey to compare the popularity of two web browsers. It was found that 75 students used browser A and 40 of tho
se students used browser B also. There were 18 students who did not use browser A but used browser B. There were 7 students who did not use either browser A or browser B.
Using a two-way table, predict the number of students who would use browser B when 300 students participate in the survey.

Answer:
The correct option is D.
Step-by-step explanation:
It is given that,
The number of students who use browser A = 75.
The number of students who use both browsers A and B = 40.
The number of students who use browsers B but not A = 18.
The number of students who did not use either browser A or browser B = 7.
From the given information, we can make a two way table as shown below.
Total number of students is 100 and 58 of them use browser B.
If 300 students participate in the survey, then the number of students who use browser B is
Therefore the correct option is D.

Answer:
Step-by-step explanation:
(A) The difference between an ordinary differential equation and an initial value problem is that an initial value problem is a differential equation which has condition(s) for optimization, such as a given value of the function at some point in the domain.
(B) The difference between a particular solution and a general solution to an equation is that a particular solution is any specific figure that can satisfy the equation while a general solution is a statement that comprises all particular solutions of the equation.
(C) Example of a second order linear ODE:
M(t)Y"(t) + N(t)Y'(t) + O(t)Y(t) = K(t)
The equation will be homogeneous if K(t)=0 and heterogeneous if
Example of a second order nonlinear ODE:
(D) Example of a nonlinear fourth order ODE:
Using the given functions, it is found that:
- Lower total cost at Jump-n-Play: 40, 64.
- Lower total cost at Bounce house: 28, 8, 30.
- Same total cost at both locations: 32.
For n visits to Jump-n-play, the cost is:
J(n) = 189 + 3n.
For n visits to Bounce Word, the cost is:
B(n) = 125 + 5n.
Comparing them, we have that:
Hence:
- For less than 32 visits, the cost at Bounce World is lower.
- For more than 32 visits, the cost at Jump-n-play is lower.
Hence:
- Lower total cost at Jump-n-Play: 40, 64.
- Lower total cost at Bounce house: 28, 8, 30.
- Same total cost at both locations: 32.
