Answer:
The mean of the combined group is 76.67 ≈ 77
Step-by-step explanation:
- The sum of the grades in Tom's group is 20×70 = 1400
- The sum of grades in Alice's group is 10×90=900
- The sum of gradees in the combined group is =1400+900=2300
- Then the mean grade of the combined group is
where
- 2300 is the sum of the all grades in the combined group
- 30 is the total number of people in the group

Answer:
dont even stress i gotchu
It's 50*, 46* and 84*.
Ratio of the second problem is 1:1 they both have a slope of 1 (which is probably why all three points are on the same line)
Step-by-step explanation:
Since we know that the straight/flat angle would equal 180* we will set the total of all those angles to 180*
We will add them up to find x. Once we find x we can find the value of each angle.
6x-10 + 4x + 6 + 7x + 14 = 180
We will combine like terms and solve for x.
17x+10 = 180
17x = 170
x = 10.
Since we have x = 10, we will plug it into x of each angle to get the value of each angle.
6(10) -10 = 60-10 which equals 50*
4(10) + 6 = 40+6 which equals 46*
7(10) + 14 = 70 + 14 which equals 84*.
