It is already simplified because there is nothing you can divide into both 18 and 25 that would result in whole numbers.
Answer:
0.108
Step-by-step explanation:
0.66 × 0.33 × 0.5 = 0.108.
Formula: L × W × H × 1/6.
L = 4
W = 2
H = 3
4×2×3.
We then have you multiply that by 1/6.
4×1/6 = 0.66.
2×1/6 = 0.33
3×1/6 = 0.5
0.66 × 0.33 × 0.5 = 0.108.
Now, onto the correct answers.
7) (4×1/6cm) × (2×1/6cm) × (3×1/6cm)
7 is correct, because the answer is diving each number by 1/6, and multiplying them with each other.
1) 1/216 × 24
1 is correct, because the answer when the question is evaluated is around 0.108. 1/216 × 24 = 0.11111111111. It is very close to the answer. This, indeed is correct.
Answer:
85
Step-by-step explanation:
64+16+4+1= 85 is the total distance i believe
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
