Each child has a 50% chance to be a girl and 50%chance to be a boy so with 4 children the probability is
-3, -2, -1, 0, 1, 2, 3, 4, 5, 6
The distance would be 9.
I apologize if I’m wrong, I’m not great at math :v
3a(4a^2 - 5a + 12)=12a^3-15a^2+36a (C)
Answer:
cost of system is $175 and cost of the games is $525
Step-by-step explanation:
Let us take the cost of the system to be X.The games cost 3 times as much as the system and are therefore given 3X. The total cost of the system and the games is $700.Therefore,we form the equation 3X+X=$700.Meaning that 4X=$700 and X is equal to $175.The cost of the system is X therefore it is $175 and the cost of the games is 3X and is therefore $525.
Answer:
Actual length of w is 0.075 units.
Step-by-step explanation:
Given the actual length of side t is 0.045 cm.
we have to use the scale drawing to find the actual side length of w.
As given the actual length of t is 0.045 cm.
Hence, we can find the scale factor using the lengths of t i.e actual length and after scale drawing by dividing.
Scale factor is ![\frac{0.9}{0.045}=20](https://tex.z-dn.net/?f=%5Cfrac%7B0.9%7D%7B0.045%7D%3D20)
Hence, we get the scale factor.
Now, ![scale factor=\frac{\text{length in figure}}{\text{actual length}}](https://tex.z-dn.net/?f=scale%20factor%3D%5Cfrac%7B%5Ctext%7Blength%20in%20figure%7D%7D%7B%5Ctext%7Bactual%20length%7D%7D)
⇒ ![20=\frac{1.5}{\text{actual length}}](https://tex.z-dn.net/?f=20%3D%5Cfrac%7B1.5%7D%7B%5Ctext%7Bactual%20length%7D%7D)
⇒ Actual length of w is ![\frac{1.5}{20}=0.075units](https://tex.z-dn.net/?f=%5Cfrac%7B1.5%7D%7B20%7D%3D0.075units)
Option B is correct.
