Answer:

2/9

Step-by-step explanation:

From the image, the total number of outcomes when two die are rolled = 36

It can also be seen that a sum of 5 can be got 4 times and a sum of 9 can be got 4 times too

Therefore, the probability of getting a sum of 5 = 4/36

Probability of getting a sum of 9 = 4/36

The probability of getting either a sum of 5 or 9 gives;

4/36 + 4/36

= 2/9

The parents organization bought 1,000 bumper stickers at $1.25 each to sell at football games.They want to make at least $750 pr

yuradex [85]

1000 x 1.25 = 1250
1000 x 2 = 2000
2000 - 1250 = 750
2000 divided by 1000 = 2

They should sell the bumper stickers for $2 each.
Hope this helped =)

Find the values of X and Y

frutty [35]

Answer:

y is equal to 2 and x is equal to 31 degrees.

Step-by-step explanation:

In order to find this, we must note that similar parts of congruent triangles are congruent. Since y is congruent to the part that is labeled 2, then it is an easy comparison.

x is a bit trickier. For this one, we must find the missing angle of the first triangle. To get that, we must subtract the given angle and the right angle from 180. This will give us x.

180 - 59 - 90 = x

31 = x
