Discuss the conditions under which P(A or B)= P(A) + P(B) is true

Mathematics
1 answer:
Andrews [41]3 years ago

That condition is true if P(A) and P(B) are independent of one another. For example, if I was pulling marbles out of a bag, if I am replacing the marbles back after I pull one out, then P(A or B) = P(a)+P(B).

Helppp!!!<br> Simplify this. Please explain it too.<br><br> 18x^4 – 3x^3 – 2x^3 + x^2 – 10 + 6
strojnjashka [21]

Answer: 18x^4 - 5x^3 + x^2 - 4

Step-by-step explanation:

We need to add like terms.

-10 and 6 are like terms

-10 + 6 = - 4

-3x^3 and -2^3 are like terms

-3x^3 + -2^3 = -5x^3

There are no other like terms.

18x^4 - 5x^3 + x^2 - 4

Answer:

51.3 degrees

Step-by-step explanation:

Use Trig Ratio to solve for theta aka the angle formed between the ;adder and the ground.

So we have the hypotenuse = 24ft and the adjacent = 15ft so I am going to use the cos ratio.

cos ∅ = a/h

rearrange for theta

∅ = cos -1 ( a/h)

now sub in the information

∅ = 51.3178

now round to the nearest tenth

∅ = 51.3 degrees

write your therefore statement

therefore, the angle between the ladder and the ground is 51.3 degrees.
