Answer:
x = 6.0
Step-by-step explanation:
As the given triangle is a right-angled triangle, we can use the trigonometric ratios to find the required length.
In the given triangle
Hypotenuse = 10
Perpendicular = x
Angle = 37°
As we know the value for perpendicular and hypotenuse, sine will be used.
Rounding off to nearest tenth
x = 6.0
Hence,
x = 6.0
Answer:
True
Step-by-step explanation:
The margin of error of a confidence interval is given by:
In which z is the critical value related to the confidence level, is the standard deviation of the population and n is the size of the sample.
So as n increases, the margin of error decreases, that is, the interval gets narrower.
The students could produce a narrower confidence interval by increasing the sample size to 100.
From the explanation above, the answer is true.
