Answer:
O Option A/1
Step-by-step explanation:
Take LCM.
4x+3(2x² - 8x) + 24x / x(2x² - 8x)
= 8x³ + 6x² - 32x² - 24x + 24x / 2x³ - 8x²
= 8x³ - 26x² / 2x³ - 8x²
= 4x - 13 / x - 4
Answer:
To use a paired t-test
Step-by-step explanation:
t-tests are essentially tests carried out to compare two different groups to check if there is a major difference in their performances or results which may be related in certain characteristics.
A paired (correlated) t-test is used when there are matched pair of similar units or instances of repeated measurements.
In this case, Mary has to use a paired t-test because the samples (students) have high similarity in characteristics. The students in question has to be from the same class to test her hypothesis (similar characteristics).
