The answer to 3) is: x = ±7
Break down the problem into these 2 equations:
x/7 = 1 and -x/7 = 1
Then solve both equation and collect all solutions.
Let me know if this helped you! Good luck Bella4992!
I think it may be 3. not sure though
Answer:
e=g = 126 degree
Step-by-step explanation:
e = g (opposite angles's property)
g+ b = 180 ( supplementary angles's property)
b = 54 degree (opposite angles's property)
-> g = 180-54 = 126
-> e = 126 degree
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).
