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>
X = soft tacos
y = double deckers
Dory:
3x + 3y = 11.25
Nemo:
4x + 2y = 10.00
---Now to solve for x and y---
---We find LCM of either x or y then make them cancel each other---
Dory multiply by 2:
6x + 6y = 22.50
Nemo multiply by 3:
12x + 6y = 30.00
--eliminate y---
Nemo subtract Dory:
6x = 7.50
Therefore x = 7.50 <em />÷ 6 = 1.25
---Now substitute x = 1.25 in either equation.---
Dory:
3.75 + 3y = 11.25
Therefore 3y = 11.25 - 3.75
therefore 3y = 7.50
there fore y = 2.50
y = 2.50 , x = 1.25
Sorry, that this is so long, I hope you understand. This is called simultaneous equations, you can read up on it.
The percentage for both the cases would be 100% and 35% respectively
Here is a proportion
5/2 = x/8
2x = 40
/2 /2
x = 20
Hope this helps
