Xy = 6
x = 2

2y = 6

y = 6÷2

y = 3

x + y = (2) + (3) = 5

(Anderson, 1.14) Assume that P(A) = 0.4 and P(B) = 0.7. Making no further assumptions on A and B, show that P(A ∩ B) satisfies 0

Goshia [24]

Answer with Step-by-step explanation:

We are given that

P(A)=0.4 and P(B)=0.7

We know that

$P(A)+P(B)+P(A\cap B)=P(A\cup B)$

We know that

Maximum value of $P(A\cup B)$ =1 and minimum value of $P(A\cup B)$ =0

$0\leq P(A\cup B )\leq 1$

$0\leq P(A)+P(B)-P(A\cap B)\leq 1$

$0\leq 0.4+0.7-P(A\cap B)\leq 1$

$0\leq 1.1-P(A\cap B)\leq 1$

$0\leq 1.1-P(A\cap B)$

$P(A\cap B)\leq 1.1$

It is not possible that $P(A\cap B)$ is equal to 1.1

$1.1-P(A\cap B)\leq 1$

$-P(A\cap B)\leq 1-1.1=-0.1$

Multiply by (-1) on both sides

$P(A\cap B)\geq 0.1$

Again, $P(A\cup B)\geq P(B)$

$0.4+0.7-P(A\cap B)\geq 0.7$

$1.1-P(A\cap B)\geq 0.7$

$-P(A\cap B)\geq -1.1+0.7=-0.4$

Multiply by (-1) on both sides

$P(A\cap B)\leq 0.4$

Hence, $0.1\leq P(A\cap B)\leq 0.4$

Answer:

The answer is b.

Step-by-step explanation:

Square root 124, you'll get 29.10, after that once you simplify it, you will get the answer and you will have to do the formula, a^2 + b^2 = c^2 since it is a triangle.

Multiply the exponent of x by 4giving The answer is x^4 evaluates to Multiply and 5 Multiply and 1 The just gets copied along. The answer is 5*x^4 evaluates to Multiply the exponent of x by 4giving The answer is x^4 evaluates to Multiply and 6 Multiply and 1 The just gets copied along. The answer is 6*x^4 evaluates to Multiply the exponent of x by 2giving The answer is x^2 evaluates to Multiply and 3 Multiply and 1 The just gets copied along. The answer is 3*x^2 evaluates to 6*x^4-3*x^2 evaluates to The answer is 6*x^4-3*x^2+7 evaluates to Multiply by we multiply by each term in term by term. This is the distributive property of multiplication. Multiply and Multiply the and Multiply and Combine the and by adding the exponents, and keeping the x, to get The answer is × = Multiply and Multiply the and Multiply and Combine the and by adding the exponents, and keeping the x, to get The answer is × = Multiply and 7 Multiply and 1 The just gets copied along.
