Answer:
What class you be taking
Step-by-step explanation:
To calculate the range of the number of students ages 7 to 18 who would likely say that "finding new resources for Earth" is the most important benefit of future flight, we need to consider the margin of error.
The margin of error (MOE) is ±3%, which means the actual percentage of students who think this way could be 3% higher or 3% lower than the survey result.
First, let's find out the percentage of students who chose "finding new resources for Earth" as the most important benefit of future flight based on the survey:
Percentage from the survey = \( \frac{4300}{40000000} \times 100\% = 0.01075\% \)
Now, we need to calculate the upper and lower bounds considering the margin of error:
Upper bound = \( 0.01075\% + 3\% = 0.04075\% \)
Lower bound = \( 0.01075\% - 3\% = -0.01925\% \)
The lower bound cannot be negative, so we consider it as 0%.
To find the number of students in the United States who would likely say that "finding new resources for Earth" is the most important benefit of future flight, we use the upper bound percentage:
\( 0.04075\% \times 40000000 = 16300 \)
So, the range is approximately 16,300 students to 4,300 students.
What are the missing numbers?
B) f(x)=(x-3)(x-1)^2
C) f(x)=(x-1)(x+1)(x+3)
D) f(x)=(x+1)^2(x+3)
The function that defines f on the xy-plane with x-intercepts at -3, -1, and 1 is f(x)=(x+1)(x-1)(x+3), which is option C in the given options.
The question asks about a function on the xy-plane that has x-intercepts at -3, -1, and 1. The function's x-intercepts are the values of x where the function crosses or touches the x-axis, which means the function's value at that point (y) is zero. The general form of a polynomial that has roots (x-intercepts) at a, b, and c is given by f(x) = k(x - a)(x - b)(x - c) where k is a constant.
In this case the x-intercepts given are -3, -1, and 1, so we need to replace a with -3, b with -1 and c with 1 in the equation. so the correct function could be f(x) = k(x - (-3))(x - (-1))(x - 1). Simplifying this further gives f(x) = k(x + 3)(x + 1)(x - 1), which matches option C. Hence, option C is the equation that defines f.
