The wood is 10 inches and you're cutting it into 1/2 pieces, so divide 10 by 1/2, which is 20, The carpenter can cut 20 dowels.
Answer:
All these rooms are rectangles so to find the
area of the rooms multiply length by width.
Living Room: 5x4 = 20 m^2
3b + 2y = 5g
20g ÷ 5g = 4
4 x 2 = 8
8 oz of yellow paint
Answer:
a
![P(E) = 0.278](https://tex.z-dn.net/?f=P%28E%29%20%3D%200.278%20)
b
![P(F |E) = 0.2353](https://tex.z-dn.net/?f=P%28F%20%7CE%29%20%3D%200.2353%20)
c
![P(E and F) = 0.0654](https://tex.z-dn.net/?f=%20P%28E%20and%20%20F%29%20%3D%200.0654)
Step-by-step explanation:
The number of vehicles available is ![N = 18](https://tex.z-dn.net/?f=N%20%20%3D%20%2018)
The number of vans is k = 5
The number of cars is n = 13
Generally P(E) is mathematically represented as
![P(E) = \frac{k}{N}](https://tex.z-dn.net/?f=P%28E%29%20%3D%20%20%5Cfrac%7Bk%7D%7BN%7D)
=> ![P(E) = \frac{5}{18}](https://tex.z-dn.net/?f=P%28E%29%20%3D%20%20%5Cfrac%7B5%7D%7B18%7D)
=> ![P(E) = 0.278](https://tex.z-dn.net/?f=P%28E%29%20%3D%200.278%20)
Generally P(F| E) means the probability that the second vehicle assigned is a van given that the first one selected is a van this mathematically calculated as
![P(F |E) = \frac{5 -1}{18-1}](https://tex.z-dn.net/?f=P%28F%20%7CE%29%20%3D%20%20%5Cfrac%7B5%20-1%7D%7B18-1%7D)
![P(F |E) = \frac{4}{17}](https://tex.z-dn.net/?f=P%28F%20%7CE%29%20%3D%20%20%5Cfrac%7B4%7D%7B17%7D)
![P(F |E) = 0.2353](https://tex.z-dn.net/?f=P%28F%20%7CE%29%20%3D%200.2353%20)
Generally
is also mathematically represented as
![P(F | E) = \frac{P(E and F)}{P(E)}](https://tex.z-dn.net/?f=P%28F%20%7C%20E%29%20%3D%20%5Cfrac%7BP%28E%20and%20F%29%7D%7BP%28E%29%7D)
=> ![P(E and F) =P(E) * P(F | E)](https://tex.z-dn.net/?f=%20P%28E%20and%20%20F%29%20%3DP%28E%29%20%2A%20P%28F%20%7C%20E%29)
=> ![P(E and F) = 0.278 * 0.2353](https://tex.z-dn.net/?f=%20P%28E%20and%20%20F%29%20%3D%200.278%20%20%2A%200.2353)
=>![P(E and F) = 0.0654](https://tex.z-dn.net/?f=%20P%28E%20and%20%20F%29%20%3D%200.0654)
Answer:
3,375 chairs
Step-by-step explanation:
The weight of 25 folding chairs is 15 kg
Number of folding chairs : weight
= 25 : 15
How many chairs can be loaded on a truck having a capacity of
carrying 2025 kg load?
Let number of folding chairs = x
Number of folding chairs : weight = x : 2025
Equate both ratios
25 : 15 = x : 2025
25/15 = x/2025
Cross product
25 * 2025 = 15 * x
50,625 = 15x
x = 50,625/15
x = 3,375
Number of folding chairs = 3,375 chairs
