Answer:
A = 178 cm^2
Step-by-step explanation:
Split the figure into a trapezoid and a rectangle
Area of trapezoid:
A = ((a+b)/2)*h
A = ((14+8)/2)*10
A = 150
Area of rectangle:
A = w*h
A = 2*14
A = 28
150+28
A = 178 cm^2

Answer:
add middle numbers and divide by two.
Step-by-step explanation:
When you need to find the median with an odd set of numbers, you arrange the numbers in order from least to greatest and find the number in the middle of the set:
1 2 3
median is 2.
But, when you have an even set of numbers, you take the two middle numbers, add them together, then divide them by two (it's like finding the mean of those two middle numbers):
1 2 3 4
2 3
2+3=5
5÷2=2.5
median is 2.5
Triangle area= b*h/2
Plug in the values:
25*8/2
200/2
100
Final answer: 100 ft^2
Answer:
Duration Recording
Step-by-step explanation:
This method records the percent of time or total time that a person exhibits a behaviour over a period of time. This type of measurement is normally used to measure behaviours that are exhibited at high rates. Normally the measurement are done from the onset of the behaviour to the moment the behaviour stops.
