Answer:

15/28

Step-by-step explanation:

The total amount of students in the class is 28. This will be useful for later.

From this table, we can see that 2 people play sports alone and 13 play an instrument alone. Since it says the number of students that play a sport or an instrument, this means that the top left box is not counted. This leaves you with an answer of 15/28.

Attorney A charges a fixed fee on $250 for an initial meeting and $150 per hour for all hours worked after that. Write an equati
Anettt [7]

let h be the number of hours then

A → C = 150h + 250 ( where C is charge )

B → C = 175h + 150

for 26 hours

A → C = (150 × 26 ) + 250 = 3900 + 250 = $4150

B → C = (175 × 26 ) + 150 = 4550 + 150 = $4700

Attorney A is cheaper for 26 hours, thus better deal

Equate the 2 equations to find hours they charge the same

175h + 150 = 150h + 250 ( subtract 150h from both sides )

25h + 150 = 250 ( subtract 150 from both sides )

25h = 100 ( divide both sides by 25 )

h = 4 ← number of hours when charges for both are equal

Thus Attorney A becomes a better deal at 5 hours

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.
