Its better to choose the simple random samples, if the defect is in every other cake, a systematic random sample could miss it completely depending on what Sergio chooses for k.
Here he is taking a random sample of cakes to get a better idea of how many cakes might have this defect.
The random sample is defined as the method of choose a sample from the group of sample and each of the sample has same probability of being chosen
The systematic sample is the method of choosing the sample from the group of sample with a periodic interval.
Here Sergio noticed a potential defect that seems to be showing in every other cake, so there will be chance of missing the defect completely
Hence, to choose the defect items, the simple random sample is better than systematic random sample.

Answer and Step-by-step explanation:
The answer would be the last answer choice.
Exponents that are the being raised by another exponent get multiplied, so 6 times -3 is -18.
When a number/variable has a negative exponent, the number/variable will be put under 1, and the exponent will change to be positive.

Answer:
1/4 the new area
Step-by-step explanation:
Kimberly wants to enlarge hut 5‘ x 10‘ rectangular patio by multiplying its dimensions by two how old the area of the patio be affected
Given that:
Initial dimension of patio = 5' by 10'
Initial area of patio = Area of rectangle = Length * width
Area of patio = 5 * 10 = 50 in²
If dimension is multiplied by 2
New dimension :
5* 2 by 10*2 = 10' by 20'
New area of patio :
10 * 20 = 200 in²
50 /200 = 1/4
The old area will be 1/4 the size of the new area of the patio
