Answer-

Set of constraints to model the problem are,

$12x+9y\geq 510\\y \leq 2x\\y \geq 25$

Solution-

Let us assume,

x = the number of lawns weeded by Gwen,

y = the number of dogs walked by Fabio.

Gwen charges $12 each time she weeds a yard and Fabio charges $9 each time he walks a dog,

$\text{Earnings of Gwen} = 12x\\\text{Earnings of Fabio} = 9y\\\text{Total earnings of Gwen and Fabio} = 12x+9y$

They need at least $510 to purchase the new gaming station, means they need $510 or more than $510.

An equation for this situation will be,

$12x+9y\geq 510$

The number of dog walked by Fabio has scheduled is no more than twice the number of yards Gwen has scheduled to weed, means y must be less than or equal to 2x.

An equation for this situation will be,

$y \leq 2x$

Fabio will walk at least 25 dogs, means y must be greater than of equal to 25.

An equation for this situation will be,

$y \geq 25$

two dice are rolled, find the probability that an even number appears on the first and the number 5 appears on the second die

lidiya [134]

Answer:

1/36

Step-by-step explanation:

Two dice are rolled.

Find the probability that;

An even number appears on the first and,
The number 5 appears on the second die

Since the two dice are rolled simultaneously, there are 36 possible outcomes:

1,1 1,2 1,3 1,4 1,5 1,6 (six outcomes)

2,1 2,2 2,3 2,4 2,5 2,6 (another six outcomes)

3,1 3,2 3,3 3,4 3,5 3,6 (six outcomes)

4,1 4,2 4,3 4,4 4,5 4,6 (six outcomes)

5,1 5,2 5,3 5,4 5,5 5,6 (six outcomes)

6,1 6,2 6,3 6,4 6,5 6,6 (six outcomes finally!)

So six by 6 is 36 outcomes

For an even number to appear on dice one, either number 2, number 4 or number 6 should apear (even numbers between 1 and 6)

The probability that an even number appears on the first die is 6/36 = 1/6

The probobility that the number 5 appears on the second die is 6/36 = 1/6

The probability that an even number appears on the first die and the number 5 appears on the second die is;

1/6 × 1/6 = 1/36

* Remember that we multiply wherever there is an 'AND' in probability!

Answer:

16.6

Step-by-step explanation:

Add the numbers together.

13.2+20=33.2

Now divide the number by 2.

33.2/2=16.6

Hope this helps!

If not, I am sorry.
