Answer:
Option b, c and e are wonderful approaches to solve the problem.
Step-by-step explanation:
Option (b) is appropriate this is because the option is talking about Simple random sampling where random universities are chosen to remove bias.
Option (c) is correct because this is an example of Stratified sampling where two homogenous groups (private and public universities are considered) and samples are chosen at random to remove bias
Option (e) is correct because this again is an example of Simple random sampling where 60 random STEM majors are chosen at random.
Answer:
20 ft × 20 ft (square has equal sides)
Answer:
f(t) = 62 ⋅ 0.9953t
Step-by-step explanation:
The function decreases at a rate of 0.47%
That will mean, the initial value decreases by 0.47?
100% - 0.47% = 99.53%
The next value will be 99.53% of the initial value.
∴ 99.53% × 62 = 0.9953 × 62.
After a time t, the value will be:
0.9953t × 62
∴ Answer = 62 × 0.9953
Answer:
This is weirdly written, but let's try to solve it:
M is the mass of Molly
A is the mass of Arthur
G is the mass of Ginny.
We can represent the weight as:
(M + A) + G
or as:
A + (G + M)
the first situation shows that Molly and Arthur are weight together (this is why their weight is shown as only one), and then they weight Ginny alone.
The second situation shows that Arthur is weight alone, and Ginny and Molly are weight together (this is why their weight is written as only one)
