Of course it is c. range would show the difference between the highest and lowest scores, there is no mode in her data set, and the median is the middle point of the data set
You can eliminate graphs A and C because the lines are dotted and you can eliminate graph B because the shaded part is below the solid line and the equation is telling you to shade above so the answer is D
They can show the rising and decreasing functions of the data.
Answer:
these are fromeast to greatest
9^10
9^5
1^3/4
1^3/20
Minimum required sample size for a desired margin of error and confidence level when it is a proportion problem: n = (z2÷margin of error2)*p-hat*q-hat
The maximum value of p-hat*q-hat occurs where p-hat = .5 (found by taking the derivative of (p-hat)*(1-p-hat) and setting it equal to 0 to find the maximum. n = ( 2.5762( for 99% confidence interval)÷.0482 )*.5*.5 = 720.028 or 721
