Answer:
A. This study is an experiment, since it was based on a random sample.
Step-by-step explanation:
Simple random sampling is a probabilistic sampling procedure that gives each element of the target population and each possible sample of a given size the same probability of being selected.
Answer:
w=35, L = 17
Step-by-step explanation:
the perimeter is all sides added together to total 104. so,
2L + 2W= 104
the width is one more than twice it's length, so W = 2L + 1
plug that into first equation.
2L + 2(2L+1)=104
distribute:. 2L + 4L + 2= 104 and continue to solve for L
6L + 2= 104 subtract 2 from both sides.
6L = 102, divide both sides by 6
L = 17. so the length is 17 ft. now use that number to put it in our equation for width, W= 2L + 1
W= 2(17)+1
W = 35
Answer:
63 = 3 × 3 × 7
Step-by-step explanation:
Here in this question, we have to write 63 as a product of its primes.
So, we have to first factorize 63 to get its prime factor.
Now, the factors of 63 are 7, 3 and 3 and all of them are prime numbers.
Therefore, we can write 63 as the product of its primes as 63 = 7 × 3 × 3 (Answer)
If we write the factors as smallest first then we have to write 63 = 3 × 3 × 7 (Answer)
To find the area of a parallelogram, you use the area formula:
Area = Base * Height
Then, all you have to do is substitute in your known integers and solve. Therefore:
Area = 15 * 21 2/3
When we multiply these two numbers, we get
Area = 325 square yards or yards
471 divided by r equals 94.2
314 divided by r equals 62.8
94.2 minus 62.8 equals 31.4
