Multiply 9 by 3.14 and then 2, the equation is c = 2piD (circumference equals two times pi times diameter)

Consider three events A, B and C with following properties.

lisov135 [29]

By the inclusion/exclusion principle,

$\mathbb P(D)=\mathbb P(A\cup B\cup C)$
$\mathbb P(D)=\mathbb P(A)+\mathbb P(B)+\mathbb P(C)-\bigg(\mathbb P(A\cap B)+\mathbb P(A\cap C)+\mathbb P(B\cap C)\bigg)+\mathbb P(A\cap B\cap C)$
$\mathbb P(D)=\dfrac14+\dfrac16+\dfrac14-\dfrac39+\dfrac1{13}$
$\mathbb P(D)=\dfrac{16}{39}\neq1$

So the union of A, B, and C does not constitute the entire sample space.

The perimeter of the picture frame is 38 inches. The width of the frame is 7 inches, what is the length?

o-na [289]

Answer:

12 inches

Step-by-step explanation:

So you know that the perimeter of a picture frame (a rectangle) is 2 widths plus 2 lengths.

Let x= lengths and w= widths

From the question we already know that w=7, so we can set up an equation that says:

2x + 2w = 38

2x + 2(7) = 38

2x+14 = 38

2x +14 -14 = 38-14

2x = 24

2x/2 = 24/2

x= 12

Since x= lengths =12

the length of the frame is 12 inches.

Estimate 8978 x 38 by first rounding each number so that it has only 1 nonzero digit.

Afina-wow [57]

Answer:

9,000 x 40 = 360,000

Step-by-step explanation:

9,000 x 40 = 360,000

A one nonzero digit is a number that has only one number that's not 0. For example, 300 has only one nonzero digit.

Hope this helps!
