How do I do this? -2(6-r)=4
2 answers:
To solve this, you need to isolate/get the variable "r" by itself in the equation:
-2(6 - r) = 4 Divide -2 on both sides
6 - r = -2 Subtract 6 on both sides
6 - 6 - r = -2 - 6
-r = -8 Divide -1 on both sides to get "r" by itself
(two negative signs cancel each other out and become positive)
r = 8
PROOF
-2(6 - r) = 4 Substitute/plug in 8 into "r"
-2(6 - 8) = 4
-2(-2) = 4
4 = 4

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>
