Answer:

0.94

Step-by-step explanation:

Formula; P(AUB) = P(A) + P(B) - P(AB).

P(A) = 0.7

P(B) = 0.8

P(AB) = 0.56

=  0.7 + 0.8 - 0.56

=  0.94

Hence, P(A U B) = 0.94

Answer:

P(A ∪ B) = 0.94

Step-by-step explanation:

P(A) = 0.7

P(B) = 0.8

P (A ∩ B) = 0.56

P(A ∪ B) = P(A) + P(B) - (A ∩ B)

⇒ P(A ∪ B) = 0.7 + 0.8 - 0.56

⇒ P(A ∪ B) = 0.94

Let P(x) = 3x³-ax+b. If P(1) = P(-1) and P(2)=16, find the values of a and b
kozerog [31]

P(1) = P(-1)

P(1) = 3 - a + b
P(-1) = -3 + a + b

-> 3 - a + b = -3 + a + b
-> 3 - a + b + 3 - a - b = 0
-> 6 - 2a = 0
-> a = 3.

P(2) = 24 - 2a + b -> 24 - (2a - b) = 16 -> 2a - b = 8
-> 6 - b = 8
b = -2.

So, a = 3 and b = -2

Recheck : P(1) = 3 - 3 + (-2) = -2
P(-1) = -3 + 3 + (-2) = -2 => P(1) = P(-1) (true)

P(2) = 24 - 6 + (-2) = 16.

jasenka [17]

Answer:

29/110

Step-by-step explanation:

There are a total of 110 orders at the restaurant, so that will serve as the denominator. There are 29 meatballs, so that will be the numerator. Combine the two and you get 29/110. Experimental probability is what happens in the experiment like this question. Theoretical probability is "real math" as in 1/3.

Match eith the appropiate property:​
kotykmax [81]

Answer:

Commutative property of multiplication.

Step-by-step explanation:

This property says that changing the order of factors doesn't change the product.

Here 5×3 will be 15..... If we interchange the places of 3 & 5 , still then the product will remain same i.e. 3×5 = 15
