Answer:
Step-by-step explanation:
Total marble = 4+6+7 = 17
Number of green = 7
Prob(1st green) = 7/17
Now their are 6 green left and 16 marble
Prob(2nd green) = 6/16 = 3/8
Now their are 5 green left and 15 marble
Prob(3rd green) = 5/15 = 1/3
Prob(1st and 2nd and 3rd green) will be = 7/17 × 3/8 × 1/3
= 7/(17×8)
= 7/136
Answer:
Yes. There is a bias in the selected sample.
Step-by-step explanation:
Population of interest = undergraduate students at the university
Respondents to email requests = 2,000 students
Sample size = 100 students
Sample is based on the 2,000 respondents.
Therefore, sample is biased.
b) A sampling method is said to be biased if it systematically favors a group. By making some members of the student population systematically more likely to be selected in a sample than others, there is an occurrence of sampling bias. Usually, findings from biased samples can only be generalized to populations that share characteristics with the sample and to the entire population of interest.
Answer:
x=0.3
Step-by-step explanation:
Let's solve your equation step-by-step.
3.7(−83x−3)=3.7(7x−30)
Step 1: Simplify both sides of the equation.
3.7(−83x−3)=3.7(7x−30)
(3.7)(−83x)+(3.7)(−3)=(3.7)(7x)+(3.7)(−30)(Distribute)
−307.1x+−11.1=25.9x+−111
−307.1x−11.1=25.9x−111
Step 2: Subtract 25.9x from both sides.
−307.1x−11.1−25.9x=25.9x−111−25.9x
−333x−11.1=−111
Step 3: Add 11.1 to both sides.
−333x−11.1+11.1=−111+11.1
−333x=−99.9
Step 4: Divide both sides by -333.
−333x
−333
=
−99.9
−333
x=0.3
Answer:
The correct option is 
= 3× 
Step-by-step explanation:
The information given are;
The condition if ΔOPQ is expanded laterally from point Q by a factor of 3
We have;
The center of dilation Q will remain in place while the segments 
Point will become 
,
Where:
is equal to 3× 
is equal to 3× 
is equal to 3× 
Therefore, in ΔO'P'Q'
is equal to 3× 
is equal to 3× 
∴ in ΔRSO, = 3×
The correct option is = 3×
