Answer:
Positive correlation if right. Atleast consider brainlist:)
Step-by-step explanation:
I think what you meant was
(2x - 5)² = 11 -- (1)
Square root both sides of (1), i.e.
√(2x - 5)² = ± √11 -- (2)
From (2), we have
2x - 5 = ± √11 -- (3)
By adding 5 to both sides in (3), we have
2x = 5 ± √11 -- (4)
Divide both sides of (4) by 2, and we obtain
x = (5 ± √11)/2 -- (5)
From (5), the solution set of (1) is
x = (5 + √11)/2, (5 - √11)/2 ...Ans.
Answer:
The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.
Step-by-step explanation:
The coefficient of variation is used to measure consistency of a data set. It is the standard deviation divided by the mean. The higher the coefficient of variation, the more variable, that is, the least consistent the data set is.
The average number of newspapers for sale in an airport stand is 15. SD is 6.
The consistency is:

The average age of the pilots is 36 and SD is 4.
The consistency is:

The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.
Answer:
QR / SQ = SQ / TQ
Step-by-step explanation:
∠QST = 90 - ∠Q
∠R = 90 - ∠Q
∠QST = ∠R
ΔQST ~ ΔQRS
SQ / TQ = QR / SQ
Answer:
The answer would be 41 when x=4
