Including circles in total shapes: 1 circle to every 5 shapes or 1:5
Step-by-step explanation:
16 ÷ 4 = 4
20 ÷ 4 = 5
The answer to this is 36.3.
Answer:
-8
Step-by-step explanation:
you need to rewrite it in y=mx+b form where b-is the y-intercept
y-4= -3(x+4)
distribute
y-4 = -3x-12
isolate y
y= -3x-8
compare this with the y=mx+b so y-intercept is -8
Absolute deviation is 92.40
Rearrange numbers from least to greatest to avoid confusion.
108, 112, 122, 145, 160
Mean = (108 + 112 + 122 + 145 + 160) / 5
= 647 / 5
= 129.40
Absolute deviation : (number - mean)
*absolute means that a number is always treated as a positive number contrary to its actual value
108 - 129.40 = 21.40
112 - 129.40 = 17.40
122 - 129.40 = 7.40
145 - 129.40 = 15.60
160 - 129.40 = <u> 30.60</u>
total absolute deviation 92.40
Mean absolute deviation = 92.40 / 5 = 18.48
The answer is 5/12 ! Because there are 12 shirts in total and 5 black shirts so there is a 5 out of 12 chance that he would wear a black t-shirt.
