{x+y=36
0.1x+0.25y=5.4
Step-by-step explanation:
just took the test sorry for being late
3s + 4 = 28 Lisa is 4 years older than three times his age. 4 years older would mean +4 , and the 3 times his age is 3s because the s represents sammys age
Meg makes a dot plot for the data 9, 9, 4, 5, 5, 3,<br>
4,5, 3, 8, 8, 5. Where does a gap occur?
Papessa [141]
The gap consists of the values 6 and 7.
Check out the dot plot below to see what I mean. We have one cluster on the left from 3 to 5. Then another cluster on the right from 8 to 9.
1.) Equal likely chance would be 50/50 for having a dog or a cat. There are 3 possibilities: one dog and one cat, 50%, two dogs, 25%, or two cats, 25%. Adding the probabilities of having two of the same pets would theoretically give you a 50% chance.
2.) If you used two coins to simulate the possible outcome of pets the family had, you would have two fair sided coins. Each coin would have one dog side and one cat side (or heads and tails, where you would assign each pet a side of the coin).
3.) You have to do the expirament on your own.
4.) Having three pets changes the probability to a 33.3% chance of having each pet. Using number one as an example, add the probabilities to get a 66.6% chance for having three of the same pets.
5.) You can change the simulation by using a 3-sided die.
2 digit meaning that it has 2 numbers. For example, 66 is a two digit number.
Now, they also said it must be prime, meaning that its factors can only be 1 and itself.
Also, it must be odd.
Answer: 67
Now, do the same, except the number must be composite, as meaning that it has other factors.
Answer: 21
