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>

Step-by-step explanation:
A ball is 10 meters. Since 100 centimeters are in a meter, each ball has 100*10 = 1000 centimeters.
The teacher needs 70 strings each 40 centimeters. The total amount they need is 70*40 = 2800 centimeters.
Since a ball has 1000 centimeters, 2800 centimeters will need 3 balls for a total of 3000 centimeters.
I am going to assume 2.5x is really 25x (typo).
First formulate the equality
![4x^2-16x+25x=0 \\4x^2+9x=0 \\x(4x+9)=0 \\](https://tex.z-dn.net/?f=%3C%2Fp%3E%3Cp%3E4x%5E2-16x%2B25x%3D0%20%5C%5C%3C%2Fp%3E%3Cp%3E4x%5E2%2B9x%3D0%20%5C%5C%3C%2Fp%3E%3Cp%3Ex%284x%2B9%29%3D0%20%5C%5C%3C%2Fp%3E%3Cp%3E)
Now two results emerge.
