Answer:1 1?4
Step-by-step explanation:
Answer:
9/4 OR 2 1/4
Step-by-step explanation:
-3/2 to the second power is -3/2 * -3/2 so you multiply the numerators together and you multiply the denominators together then put it back as a fraction
-3 *-3 = 9
2 *2 =4
9/4 or in mixed form 2 1/4
Answer:
Step-by-step explanation:
For this case we have the following info given:
Treatment: 12 13 15 19 20 21 24
Control: 18 23 24 30 32 35 39
We can find the sample mean and deviations with the the following formulas:
And repaplacing we got:
the sample mean for treatment
the sample mean for treatment
the sample deviation for treatment
the sample deviation for control
the sample size for each sample
The degrees of freedom are given by:
The confidence interval for the difference of means is given by:
The confidence is 98% so then the significance is 
and 
. Then the critical value would be:
And replacing we got:
The polynomial function that could represent the graph is f(x) = x²(x - a)(x - b)² with four turning points
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The maximum number of turning points of a polynomial function is always one less than the degree of the function.
Hence the polynomial represented by the graph is of degree 5 since it has 4 turning points. The polynomial function that could represent the graph is f(x) = x²(x - a)(x - b)²
