Answer:

A. There is a 1/4 chance.

Step-by-step explanation:

There are 8 outcomes if a coin is flipped 3 times.

Of these, 4 start with tails.

Since 4 is the denominator here, C (3/8) is out.

Also 4 doesn't have 3 as a factor, so B (1/3) is also out.

After the tails flip, two heads follow.

That's one of four of the combinations starting with tails (THH, THT, TTH, TTT, so D is out, leaving A as our answer! (We would need two for A to work)

Your office needs to deliver products to various sites in your town. You can hire a firm to make those deliveries for $200 per m

Zigmanuir [339]

Hire firm:
200+0.50*1200 each month
200+600=800

lease truck:
350+480 each month
=830

so with contracting a firm instead of leasing trucks you would save 30$ each month or 30*12=360$ each year

This is a special type of equations where all the unknowns must be integers and limited to a range [0,9] because they are the digits of a number.

Let's say Cathy was born in the year x formed by the ordered digits abcd. A number expressed by its digits can be calculated as

$x=1000a+100b+10c+d$
