Answer: BE = 48 cm
Step-by-step explanation:
BE is twice as long as AB so to find BE just multiply 2 by 24.
2 × 24 = 48
Answer:
Step-by-step explanation:
<u>Given equation</u>
- f(t) = 2^(kt)
- f - number of cells, t - number of months, k- coefficient
<u>We got 32 cells in the first month. It means:</u>
<u>Using these numbers we can find the coefficient k:</u>
- 32 = 2^(k*1)
- 2^5 = 2^k
- k = 5
<u>Then the equation becomes:</u>
<u>Average time is 9 months, we can calculate the number of cells:</u>
- f(9) = 2^(5*9) = 2^45 ≈ 3.5*10^13
Answer:
52
Step-by-step explanation:
the answer is 52 because all the angles have to add up to 360 and 128+126+54=308 and 360-308=52
Using sampling concepts, it is found that the correct option is:
b. The 9000 registered voters from California in the database.
Example of sampling, involving sample and population:
I survey 1000 randomly selected residents of New York State, asking if they are Buffalo Bills fans or not.
- The <em>sample </em>is the 1000 residents surveyed.
- The <em>population </em>is all New York State residents, as it is the pool with all available options to be sampled.
In this problem, 1000 registered voters in California are randomly selected from the database and asked their opinion, hence:
- The 1000 voters are the sample.
- The pool with all available options to be sampled is the <u>9000 registered voters in California from the database</u>, hence, it is the population, and option b is correct.
