Answer:

Step-by-step explanation:
We are given the following in the question:

Let l be Lyle's height, h be Harry's height and v be Vince's height.
Thus, we can write:

Lyle's Height =

Harry's height =

Putting the value in the equation:

Thus, Vince's height is 3.5 feet.
Answer:
it should be 12/2 or 6 i believe
Step-by-step explanation:
4x4 = 8
8x2 = 16
16-4 = 12
The first sampling method is Convenient Sampling. It is biased sampling and it is not representative of a random sample.
The second sampling method is Systematic Sampling. If this method of sampling is drawn from the population, it is an efficiently randomized sampling method.
Let us review the given answers.
1. Both samples should be exactly the same.
INCORRECT
2. Neither sample will be representative.
Because the second sampling method can be random, this answer is
INCORRECT.
3. The first sampling method, ..., is the most representative,
INCORRECT
4. The second sampling method, ..., is the most representative.
CORRECT
Answer: There are 3 quarts of concentrate and 9 quarts of water.
Step-by-step explanation:
Since we have given that
Ratio of number of quarts of water to number of quarts of concentrate is
3:1
Number of quarts of orange juice from concentrate and water = 12 quarts
So, the number of quarts of concentrate would be

the number of quarts of water would be

Hence, there are 3 quarts of concentrate and 9 quarts of water.
Answer:
- 23
Step-by-step explanation:
We could do this the long way and expand the whole product or note that the
terms arise from the product of the a³ and a terms and the product of the a² and a² terms, that is
4a³ × 3a = 12
+ 5a² × - 7a² = - 35
Summing gives
12
- 35
= - 23
with coefficient - 23
