Answer: The scale is 5cm/m (5 cm in the drawing are equivalent to 1 meter on the actual pit)
Step-by-step explanation:
When we have an original measure M, and we redraw it with a new scale, where the new measure is m, the scale used is equal to:
scale = m/M.
In this case, we know that:
The pit is 3m, by 5m
and the drawing to scale is 15cm by 25cm
(15cm is the rescaled version of the 3m side, and 25cm is the rescaled version of the 5m side)
Using the equation above, we can find that the scale is:
Scale = 15cm/3m = 5cm/m
and, if we use the other side, we get:
Scale = 25cm/5m = 5cm/m
Both calculations give the same scale, as expected.
Then the scale is 5cm/m, which means that 5 centimeters in the drawing are equivalent to one meter in the real pit.
Do you mean hunderths 0.06 if its regular its 000
Answer:
I think it might be option 3
Step-by-step explanation:
sorry if I’m wrong
The <span>height of the tower. is 27 m
Now, we write h/x = tan 45
i.e h/x = 1
i.e h = x ...........................1.
Now, h/(x+20) = tan 30
i.e </span> (x+20)/h = 1/tan 30
or (x+20) = 1.73h
or from equation 1 ,
h+ 20 = 1.73 h
20 = 1.73h - h
h = 20/0.73
or h = 27.39 = 27 m

![X \sim Unif (a=40, b=60)](https://tex.z-dn.net/?f=X%20%5Csim%20Unif%20%28a%3D40%2C%20b%3D60%29)
And for this case we want to find the probability density function and we know that is given by:
![f(x) =\frac{1}{b-a}=\frac{1}{60-40}= \frac{1}{20}, 40\leq X\leq 60](https://tex.z-dn.net/?f=%20f%28x%29%20%3D%5Cfrac%7B1%7D%7Bb-a%7D%3D%5Cfrac%7B1%7D%7B60-40%7D%3D%20%5Cfrac%7B1%7D%7B20%7D%2C%2040%5Cleq%20X%5Cleq%2060)
Step-by-step explanation:
Let X the random variable who represent the length of time it takes students to complete a statistics examination. And the distribution for x is given by:
