Answer:
A recent study shows that about 43% of medical doctors have a solo practice with a margin of error of 4.6 percentage points.
Step-by-step explanation:
Given that a random sample of 311 medical doctors showed that 135 had a solo practice.
Sample proportion = 0.43
Std error of sample proportion =
Margin of error 90%
Margin of error in percent = 4.6%
Hence correction option is:
A recent study shows that about 43% of medical doctors have a solo practice with a margin of error of 4.6 percentage points.
Answer:
x = 40°
Step-by-step explanation:
Reference angle = x°
Adjacent side length to reference angle = 7.2
Hypotenuse = 9.4
Apply trigonometric function CAH, which is:
Cos x = Adj/Hyp
Substitute
Cos x = 7.2/9.4
Cos x = 0.76596
x = 40° (nearest tenth)
