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>
Answer:
Step-by-step explanation:
1)
Area) = area of square + area of triangle
square = 6*6 = 36
area of equilateral triangle = ( / 4) *a^2 = 31.1759
total area = 36 + 31.1759 = 67.1769
Perimeter) 6*5 = 30 "
2)
Area) = upper triangle + lower square
6* *sin(45) = 6 cm ( each side is 6)
upper triangle = 1/2*6*6 = 18
lower square = 6*6=36
total area = 38 + 18 = 56
perimeter = 4*6+6* = 32.4852 cm
3)
Area) = left triangle + right rectangle
left triangle = 1/2*3*4 = 6 ( this is the famous 3,4,5 triangle )
rectangle = 8*3 = 24
total area = 24+6=30
perimeter = 8+5+3+8+3= 27'
