The correct answer is
18 CM
because RX = 2/3(27) = 18
(Enter 18 in the box)
Answer:
2,436 students
Step-by-step explanation:
At a 90% confidence level, the z-score is 1.645 and the confidence interval is given by:

Where s is the standard deviation, and n is the sample size.
If they want the length of their confidence interval to be no greater than 0.2, it must be no further than 0.1 from the mean 'X':

Rounding up to the next whole number, the sample size should be 2,436 students.
Answer:
One of the answers are a negative number.
Step-by-step explanation:
A) Look at how the negatives are compared to the others
B) The negatives goes to the left since it's decreasing
C) Although they're the same numbers but that minus sign in front of a number is representing a decreasing number. The other numbers on the right are positive which means it's increasing.
I learned it this way, but I hope this helps you. Good Luck
-4y = 8x
y = 8x/-4
y = -2x
The constant of variation is -2
IF sides AC and BC are the 'legs' of the triangle, then the length of the 3rd side is
√ (5² + 6²) = √(25 + 36) = √61 = 7.81 (rounded)
IF side BC is the longest side (hypotenuse) of the triangle, then the length of
the 3rd side is
√(6² - 5²) = √(36 - 25) = √11 = 3.32 (rounded)
