Answer:
- <u><em>Option b. just below 30%</em></u>
<u><em></em></u>
Explanation:
Please, see attached the <em>histogram that represents the distribution of acceptance rates (percent accepted) among 25 business schools in 2004. </em>
<em />
The<em> median</em> is the value that separates the lower 50% from the upper 50% of the data.
Since there are 25 business schools, the middle value is the number 13.
The height of each bar is the<em> frequency</em> or number of business school for that acceptace rate:
- The first bar has frequency of 1 school
- The second bar has frequency of 3 schools: cummulative frequency: 1+3=4.
- The third bar has frequency 5 schools: cummulative frequency 4 + 5 = 9.
- The fourth bar has frequency 3 schools: cummulative frequency: 9+3=12.
Then, the 13th value is on the next bar, the fifth bar.
The fifth bar has acceptance rates 25 ≤ rate < 30.
That means that the median acceptance rate is greater than or equal to 25 and less than 30.
Thus, the choice is the option <em>b. just below 30%.</em>
M2. A (Estimated Difficulty Level: 3)
<span>Try plugging in some real numbers until you get one of the answers. For example, if you choose 4, then </span>calcu- late<span> 2×4+42 +1 = 25. The answers don’t list 25, so choose another integer to start with. If you choose 5, you’ll get 2 × 5 + 52 + 1 = 36, so the answer is A.</span>
<span>If you are an algebra fiend, you may notice that if the integer is x, then the calculation is 2x+x2+1 = (x+1)2, so the final sum must be the square of an integer. Only answer A is a perfect square.</span>
Answer:
it is 2.66*
Step-by-step explanation:
24 / 9 = 8/3
8/3 = 2.66*
Answer:
you can use it in architecture and construction
Step-by-step explanation:
say you are building a sloped roof. If you know the height of the roof and the length for it to cover, you can use the Pythagorean Theorem to find the diagonal length of the roof's slope. You can use this information to cut properly sized beams to support the roof, or calculate the area of the roof that you would need to shingle. I hope this helps!
