Answer:

A = 9.9648

Step-by-step explanation:

if the triangle is equilateral =>

P = 3L => L = 14.4/3 = 4.8

A = L²√3/4

= (4.8)²√3/4

= 23.04√3/4

= 5.76×1.73

= 9.9648

An observational study determined that there is a strong correlation between getting less than 8 hours of sleep a day and lower
s2008m [1.1K]

Answer:

No

Step-by-step explanation:

We can not determine that the low test scores are caused by sleep deprivation. Because there are many factors that can affect on a student's test score such as:

  • not carefully review all the lesson before the test
  • the feeling of nervous in the exam room
  • poor academic ability
  • ....so on

So, getting less than 8 hours of sleep is just one of the independent variables determining the test score, it is not a strong correlation.
