Answer:
There are 11 different sums.
Step-by-step explanation:
When you roll two dice, the smallest number you can get is 2, and the largest 12, and you can get all in between. So 12-2 is equal to 10, but we have to add another 1 because 2 counts. So the answer is 11.
Answer:
3 friends are older than the average.
Step-by-step explanation:
First find the mean. The mean can be found adding all the numbers in the set together and dividing by the amount of numbers in the giving set:
(25 + 36 + 33 + 36 + 30)/5 = (160)/5 = 32
The average age is 32. There are 3 friends that are older than the average (33 , 36 , 36, respectfully).

Answer:
can u help me with this science questions {Mr. Dyers’ daughter is feeling ill. The doctor determines that she has the common cold. What would be the best treatment the doctor could suggest?}
Step-by-step explanation:
Answer: b = 69
The slashes mean the opposite angles are the same. This is and isosceles triangle, which mean two sides are the same and one is not.
A triangle = 180
We know one angle is 42 and the other two angles are the same.
Subtract 42 from 180
180 - 42 = 138
Now the 138 is going to two sides but we know they are equal so we can divide 138 by 2
138 divided by 2 = 69
So b = 69
Answer:
y = x^2 +8x +16
Step-by-step explanation:

x + 4 = t
y = t^2 = (x +4)^2
y = x^2 +8x +16
