I just solved it and I'm pretty sure its only one solution, I took the bottom equation multiplied it by -3 then i canceled out the equations and got 9. So that would make it C.
Length = 3cm
1/2 cm cube = 3 ÷ 1/2 = 3 x 2 = 6
Width = 4cm
1/2 cm cube = 4 ÷ 1/2 = 4 x 2 = 8
Height = 5cm
1/2 cm cube = 5 ÷ 1/2 = 5 x 2 = 10
Number o 1/2 cubes = 6 x 8 x 10 = 480
Answer:
79.31%
Step-by-step explanation:
First we need to find the total number of students.
We do that summing all the four values in the table:
Total students = 2 + 18 + 3 + 6 = 29
Then, the students that play a sport or an instrument are all student but the ones that don't play both:
Students(sport or instrument) = 29 - 6 = 23
So the probability of a random student playing a sport or an instrument is 23/29 = 0.7931 = 79.31%
