Use the Intermediate Value Theorem to show that there is a root of the given equation in the specified interval. x4 + x − 7 = 0, (1, 2) f(x) = x4 + x − 7 is ---Select--- on the closed interval [1, 2], f(1) = , and f(2) = . Since −5 < ? < 11, there is a number c in (1, 2) such that f(c) = ? by the Intermediate Value Theorem. Thus, there is a ---Select--- of the equation x4 + x − 7 = 0 in the interval (1, 2).

In the diagram below, tan θ = sqrt 3. what is the value of m?

Two students were asked if they liked to read. is this a good example of a statistical question? why or why not? a yes, this is a good statistical question because a variety of answers are given. b yes, this is a good statistical question because there are not a variety of answers that could be given. c no, this is not a good statistical question because there are not a variety of answers that could be given. no, this is not a good statistical question because there are a variety of answers that could be given

The distribution of the amount of money spent by students for textbooks in a semester is approximately normal in shape with a mean of $235 and a standard deviation of $20. according to the standard deviation rule, how much did almost all (99.7%) of the students spend on textbooks in a semester?
