The volume of a prism is just its width times its height times its length.
v=whl
v=2×4×5
v=40
So we know the volume is 40 units. But which units?
Matt used centimeters as his units, so his rect. prism's volume would be 40 cm³. Mindy's would be 40 in³.
Answer:
3 mph
Step-by-step explanation:
12 divided by 4 is 3
Procedure:
1) calculate the number of diferent teams of four members that can be formed (with the ten persons)
2) calculate the number of teams tha meet the specification (two girls and two boys)
3) Divide the positive events by the total number of events: this is the result of 2) by the result in 1)
Solution
1) the number of teams of four members that can be formed are:
10*9*8*7 / (4*3*2*1) = 210
2) Number of different teams with 2 boys and 2 girls = ways of chosing 2 boys * ways of chosing 2 girls
Ways of chosing 2 boys = 6*5/2 = 15
Ways of chosing 2 girls = 4*3/2 = 6
Number of different teams with 2 boys and 2 girls = 15 * 6 = 90
3) probability of choosing one of the 90 teams formed by 2 boys and 2 girls:
90/210 = 3/7
