Answer:
Step-by-step explanation:
hello :
y=9×+5
y=9×-7
9x+5 = 9x-7
5=-7 false .....no solutions
So the equation to begin with looks like this: 4(2x+5)-7, and once you solve it: (8x+20)-7, and then to 8x+13. Thus 8x+13 is your answer.
Answer:

Answer:
D. This scenario should be analysed using paired data because the groups are dependent and have a natural pairing.
Step-by-step explanation:
Paired Data can be defined as data set, when sample units of one data set are related to sample units in other data set.
Research Study about spouses number of hours of sleep each night is paired data. As, each man in the male sample group is related to a corresponding woman (his wife) in the female sample group. So, they have a natural paring & they, their sleep schedules are dependent on each other.
