Answer:
Infinite number of solutions.
Step-by-step explanation:
Y=5x+1
-5x+Y=1
substitute value of y in first equation (5x+1) into 2nd equation
-5x+5x+1=1
0+1=1
1=1
since answer equals on both sides of the equatio, the answer is determined to be infinite.
Log base 2 64-log base 2 (4) can be written as
log base 2 (64/4)
log base 2 16
that is equal to 4 log base 2 (2)
so ans is 4
-0.1 - (x) = 0.3
-0.1 - (-0.4) = 0.3
-0.1 + 0.4 = 0.3
0.3 = 0.3 (true)
-0.4 is your answer
hope this helps
Answer:
The correct option is 2. At least 3 schools have participated for 6 years or more.
Step-by-step explanation:
From the given information it is clear that the first quarterly of the data is 2 and the third quarterly is 6.
The box plot is shown below.
Since 6 is third quarterly it means 6 divides the data in 75% and 25%.
So, 25% schools have participated for 6 years or more.
Number of terms =12
Therefore, at least 3 schools have participated for 6 years or more. Option 2 is correct.
