A math teacher asked 60 randomly selected 7th graders whether they are left handed or right handed. The table below shows the results of the survey. A school has a total of 280 seventh-grade students. Based on the results shown in the table above, how many of those seventh-grade students would you expect to be left-handed? A. 60
B. 72
C. 84
D. 120

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

i got 10.28 but that rounds up to 10.3

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
