The shape of a quartic with a negative leading coefficient most closely resembles what letter
1 answer:
Answer:
M
Step-by-step explanation:
A quartic equation/function is a fourth degree polynomial. The general form is:
We can put any values for the variables a, b, c, d, and e.
The general shape of a fourth degree polynomial is in the shape of the English letter "W".
The leading coefficient is the value of "a".
If a is negative, the curve gets upside down, so a "W" going upside down would resemble an "M".
A graph of a quartic with negative leading coefficient is shown attached. The equation is:

Answer:
The 95% confidence interval is
Step-by-step explanation:
From the question we are told that
The sample mean difference is
The standard error is SE = 0.03
Given that the confidence interval is 95% then the level of significance is mathematically evaluated as
Next we obtain the critical value of from the normal distribution table, the value is
Generally the margin of error is mathematically represented as
substituting values
The 95% confidence interval is mathematically represented as

Answer:
Except table 2, all tables have greater unit rate than the graph.
The required arrangements of tables is
Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < table 7 < Table 6
Step-by-step explanation:
Formula for unit rate :
From the given graph it is clear that the line passes through the points (0,0) and (11,20). So, unit rat of graph is
Similarly, we need to calculate the unit rate for each table.
Except table 2, all tables have greater unit rate than the graph.
The required arrangement of tables is
Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < Table 7 < Table 6
