The mean will change because the total number of dot will increase and a bigger mean than the previous will occur. The new mean is 4. The old mean is 3.75.
Step-by-step explanation:
(x - 3)(x + 5) + (x - 3)(2x - 1)
We can factor out (x - 3) since both terms have that in common. Then we simply add together x + 5 and 2x - 1
(x - 3)(3x + 4) is the final answer.
Answer:
10
Step-by-step explanation:
The median of a triangle, when bisected by other medians has a 2:1 ratio. So the longest part is twice the length of the shorter one. Since median YJ is 15, when divided by 3, it has equal parts of 5. 5*2= 10. And so segment ZY is equal to 10.
Answer:
The common denominator is 8
-6/8+5/8
