Let A and B represent the governor's salaries of states A and B, respectively.
A - B = 53,435
A +B = 290,395
Add these two equations to eliminate B.
2A = 343,830
A = 171,915
B = A -53,435 = 118,480
The governor of state A has a salary of 171,915.
The governor of state B has a salary of 118,480.
Answer:
unbiased sample values
Step-by-step explanation:
Unbiased sampling involves eliminating any form of bias in the method of selection of participants in a study in order to draw a conclusion about the population.
Paul had introduced bias in the sampling that out to look at the number of hours a day the typical student studies by introducing the variable of studying during the final exam period.
Most likely all student will study during the final exam period. This will not truly represent the study pattern of the sample population and equal chance of selection of study hours of the students. Hence paul had violated the requirement of unbiased sample values for probability sampling by not doing a random selection or systematic random selection
Answer:
Step-by-step explanation:
given.quesion.
The length of a rectangle is decreased by 25% and the width has increased by 40% calculate the percentage change in the area of the rectangle
to. find.
area of the rectangle
given
decreased. 25•/•
increased.40•/•
solusion
Length = L
Breadth = B
Original area = L x B
New area = A = L x (1 - 25%) x B x (1 + 40%)
A = L x B x 0.75 x 1.40 = L x B x 1.05
Therefore the area of the rectangle has increased by 5%.
