Step-by-step explanation:
One inequality could be x > 3. So when x = 4 this is true because 4 is greater than 3.
There are two choices for each child: overweight (o) or underweight (u). So if the first child is o the next can be o or u. If the first is u the second can be o or u. This gives four possibilities. Here the first child is the letter noted first and the second is the one listed second:
OO
OU
UO
UU
There are 4 outcomes and if each is equally likely then the probability of each is 1/4. Thus the probability of UU is 1/4
The probability of one underweight and one over weight is 1/2 because in two of the outcomes listed above there is one O and one U (namely OU and UO). Since there are 4 outcomes the probability is 2/4 = 1/2
The correct answers are:
Exact volume =

in^3
Approximate volume = V = 33.51 in^3
Explanation:The volume of the sphere is:

Since r = 2 in
Hence

in^3
(exact)
V = 33.51 in^3 (approximate)
Answer:
10.68 ft
Step-by-step explanation:
sin(62.87)=x/12
12sin(62.87)
=10.68 ft
The answer is D. Since the x line is seconds and y is feet traveled it would mean that the train travels 180 feet in 3 seconds
