Answer:
52.88 degrees
Step-by-step explanation:
To find the angle of elevation, we just need to use the tangent relation of the angle, as this relation is expressed as the division of the opposite side (that is, the height of the tree) by the adjacent side (that is, the length of the shadow), so we have that:
tangent(angle) = 37/28 = 1.3214
angle = arc tangent (1.3214) = 52.88 degrees
Answer:
Rational Number
Step-by-step explanation:
A rational number is, by definition, a number that can be expressed as the quotient or fraction of p/q of two integers, a numerator <em>p</em> and a non-zero denominator <em>q</em>. 33/3 is a fraction of p/q of two integers, a numerator <em>p</em>, or 33, and a non-zero denominator <em>q</em>, or 3. This makes 33/3 a rational number.
Answer:
B) μD = 0.60 ± 0.10(1.397)
Step-by-step explanation:
The confidence interval is given by:
Where
MD=60
n=9
df=n-1=8
Then the confidence interval is
μD=0.60±1.397*(0.3/√9)
μD=0.60±0.10*(1.397)
