Answer:
4
Step-by-step explanation:
From the question,
Since both rectangle has a scale factor of 2,
L₁/L₂ = 2
Where L₁ and L₂ are the length of the first and second rectangle respectively
L₁ = 2L₂................ Equation 1
Also,
W₁/W₂ = 2............ Equation 2
Where W₁ and W₂ are the Width of the first and second rectangle respectively
W₁ = 2W₂
Area of a rectangle = Length × width
Area of first rectangle = L₁×W₁ = 2L₂×2W₂ = 4L₂W₂
Area of second rectangle = L₂×W₂= L₂W₂
The ratio of area = Area of the first rectangle/Area of the second rectangle = 4L₂W₂/L₂W₂ = 4

Answer:
∠ ABD = 42°
Step-by-step explanation:
∠ ODC = 90° ( angle between tangent and radius )
∠ ADC = 90° - 48° = 42°
The angle between a tangent and a chord is equal to the angle in the alternate segment, that is
∠ ABD = ∠ ADC = 42°
Answer: The point estimate of the population mean and margin of error for the confidence interval is 22 and 6 respectively.
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where is the sample mean and E is the margin of error.
Given : Lower bound is 16 and upper bound is 28
Then, and
Adding both equations , we get
Put in first equation, we get
Hence, the point estimate of the population mean and margin of error for the confidence interval is 22 and 6 respectively.
