Answer: 3.75
Step-by-step explanation:
P=0.50, n=15
np= 0.5x15 gives 7.5
n(1-p)= 15x(1-0.5)=7.5
Both are greater than 5
Then Mean, u=np;15x0.5=7.5
Standard deviation, √np(1-p)
15x0.5(0.5)= 3.75
Answer:
26m
Step-by-step explanation:
To find the perimeter of a figure, you have to add up all the sides. 10 + 2 + 2 + 3 + 1 + 8= 26, therefore the perimeter of the figure is 26 m.

Answer:
Slope is 1/4
Step-by-step explanation:
Count the rise over run from somewhere the line is matched up with a whole point, like 20 or 60. The next place the point is a whole (if starting from 20) is 60. Run is 4. The Rise from 20 to 60 is 1
