Answer:
A
Step-by-step explanation:
A because the mean absolute deviation of an eighth grade class is less than that of a seventh grade class. Also, the class size is larger on average for eighth graders (35>31).
If x=n then it would have 2 solutions because it would be x^2 = c which has a positive and negative solution but idk if that is what you are asking for
Answer:
Graphs 1, 2, 3
Step-by-step explanation:
Graph 1 represents a <u>linear function</u> with a domain containing all real numbers, as any input substituted into the equation or function will produce a corresponding output. The arrows on the opposite ends of the line represents the infinite input values that have its corresponding output values.
Graph 2 represents a <u>quadratic function</u> with a domain containing all real numbers, as it does not have any constraints in terms of input values. As it opens up, the graph of the parabola infinitely widens (horizontally).
Graph 3 represents an <u>absolute value function</u> with a domain containing all real numbers. Similar to the explanation for graph 2 on quadratic functions, the downward-facing graph of the given absolute value function widens infinitely horizontally, as it does not have any constraints on input values.
7x=n that's what my mom said at least
225/5 = 360/x
225x = 1,800
225x/225 = 1,800/225 = 8
It would take him 8 minutes
