25 percent because there’s 2 cubes which puts it in 50% then you half it again because there’s 3 even numbers & 3 odd numbers so the chance will be 25%

Answer:

P(system) = p(subcomp1 ∩ subcomp2)

P(system) = 1.60 x 0.64

P(system) = 1.0240

Step-by-step explanation:

In the system we have 2 subsystem

Let say subsystem 1 and subsystem 2

Subsystem 1 consist of 2 components, component 1 and component 2 that subsystem 1 works if and only if either component 1 or component 2 work

I.e p(subcomp1) = p ( comp1 | comp2)

Since the P(component works) = 0.80

Therefore P(subcomp1) = p(comp1) + p(comp2)

= 0.80 + 0.80

P(subcomp1) = 1.60

Subsystem 2 consist of 2 components, component 3 and component 4 that subsystem 2 works if and only if both component 3 and component 4 work

I.e p(subcomp2) = p ( comp3 ∩ comp4)

Since the P(component works) = 0.80

Therefore P(subcomp2) = p(comp3) x p(comp4)

= 0.80 x 0.80

P(subcomp2) = 0.64

Therefore since the component are independent of one another

P(system) = p(subcomp1 ∩ subcomp2)

P(system) = 1.60 x 0.64

P(system) = 1.0240

ss7ja [257]

S = 0.72 m, t=0.63 s
s = a · t² /2
0.72 m = a · (0.63 s )² / 2
a · 0.3969 s² = 1.44 m
a = 1.44 m : 0.3969 s² = 3.628 m/s²
The magnitude of the acceleration due to gravity on the planet is 3.628 m/s²

What statement is an example of addition property of equality

Flura [38]

Answer:

The formal name for the property of equality that allows one to add the same quantity to both sides of an equation. This is one of the most commonly used properties for solving equations.

The formula tells us that if a = b, then a + c = b + c. The letters a and b stand for two separate numbers, our two twins, and the letter c stands for what we give to each twin to keep them matching. So, for example, if we add 1 to the left side of the equation, we must also add 1 to the right side of the equation. By doing this, we keep the equation, the twins, the same.
