<span>The distance to the base of the tower is
tan 40=100/x
x=100/tan 40=119.18 m
from the top of the building, we know the adjacent side but not the opposite
tan 30=opposite/119.18
opposite is 119.18*tan30=68.81 m
The opposite side is the height of the tower ABOVE the apartment building. The tower itself is 100 m high, and the remainder of the height, 31.19 m, is the height of the building.</span>
Answer:
I honestly used google.
Step-by-step explanation:
It means: In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form".
Answer:
Step-by-step explanation:
Given that in the general population in the US, identical twins occur at a rate of 30 per 1,000 live births. A survey records 10,000 births during Jan 2018 to Jan 2019 and found 400 twins in total.
From the above we find that population proportion is 0.03 and observed sample proportion is 0.04
So option a) is wrong
b) Correct
c) correct
d) Wrong
e) wrong
f) wrong
g) incomplete sentence
h) wrong
