For #3 you first need to know how many inches = a foot and 12 inches = a foot. So The answer would be for feet. The sentence would say, 3 feet. For the teacher you first need to know how many inches is your teacher desk. My teacher's desk is 36 inches. Since 12 inches equal a foot, we can divide 36 by 12 and we would get 3. So for mine my teacher's desk would be equal to 3 foot. The sentence would be: 3 foot. Together the complete sentence is: 3 rulers or 3 feet.
If x∆y = 3x - y², then
5∆1 = 3×5 - 1² = 15 - 1 = 14
and
14∆6 = 3×14 - 6² = 42 - 36 = 6
So (5∆1)∆6 = 6.
Answer:
80
Step-by-step explanation:
every triangle, no matter what shape or size, will have all angles add up to 180 degrees so 180-40-60=80
Answer:
The probability that the 2nd Heads occurred at the 4th toss is 5.99%.
Step-by-step explanation:
Given that there were 4 Heads in the first 7 tosses, to find the probability that the 2nd Heads occurred at the 4th toss the following calculation must be performed:
7 - 4 = 3
4/7 x 3/7 x 3/7 x 4/7 = X
0.571 x 0.428 x 0.428 x 0.571 = X
0.0599 = X
Therefore, the probability that the 2nd Heads occurred at the 4th toss is 5.99%.
