Answer:
Step-by-step explanation:
b. An experiment deliberately imposes some stimuli on individuals to observe their responses whereas a survey aims to gather information without affecting the individuals.
Hence, the data was obtained in a SURVEY as the consumption of drug was not forced.
c. Given Data:
x = 63
n = 3980
The probability will be the number of successes divided by the sample size:

The total number of successes is the product of the sample size and the probability of occurrence of tissue abnormalities.

d. As we have no data pertaining to the population of women who did not take the drug, we cannot make estimate about the number of women that will have abnormalities.
e. Larger values of sample reduces the effect that outliers can cause on the skewness of the data. As a result the interpretations are more reliable. Hence, use of large sample sizes is necessary because people's lives could be at stake.
Answer: if you're solving by x it would be x=43/2

Answer:
C) The initial number of leaves on the plant was 3.
Step-by-step explanation:
The plant has initially 3 leaves and is multiplied by 2 every week. Therefore, the answer is C.
Answer:
= - 7n - 1
Step-by-step explanation:
There is a common difference between consecutive terms , that is
- 15 - (- 8) = - 22 - (- 15) = - 29 - (- 22) = - 36 - (- 29) = - 7
This indicates the sequence is arithmetic with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 8 and d = - 7 , then
= - 8 - 7(n - 1) = - 8 - 7n + 7 = - 7n - 1
V=s³
V=25³=15625
Volume of a cube with the length of the side equal to 25 is 15625
