Answer: The scale factor of ABC to DEF is 5.

Step-by-step explanation:

Knowing that the side ratios are the same because the triangles are similar, you can use ratios to solve for x and y.

Side AB and Side DE are similar. The former has a length of 3 and the latter has a length of 15, which means that the triangle on the right is 5 times larger than the triangle on the left.

Using this information, you can solve for x by dividing 38.5 by 5.

X = 7.7.

You can then multiply 8 by 5 to solve for y, so y = 40.

X = 7.7, y = 40.

Scale factor is 5.

Expand first and then move all the x terms to one side.

make sure when u are moving the x terms flip the sign AND inequality sign.

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