Answer:
A. 18.4
Step-by-step explanation:
The mean is the average. In order to find the answer you must add all the values of the variables and divide them by the number of variables. Simply just add 14, 15, 18, 20, and 25, and then divide it by 5 (the number of variables). Then you get your answer.
14+15+18+20+25=92
92/5=18.4
A. 18.4
We will use the circumference formula to find the radius and then multiply it by 2 to find the diameter.
C = 2πr
31.4 = (2)(3.14)(r)
31.4 = 6.28r
5 = r
So our radius is 5 in.
We can multiply it by 2 to get the diameter.
5*2 = 10
So the diameter is 10 inches
Answer: p = 1/5
Step-by-step explanation:
-5(p + 3/5) = -4
Now we open the brackets and -5 mutiplies with both terms
-5p - 3 = -4
-5p = -4+3
-5p = -1
p = -1/-5
p = 1/5
