Answer:
The answer to your question is 200 visitors went to screen 1
125 visitors went to screen 2
175 visitors went to screen 3
Step-by-step explanation:
Data
3 screens
total number of visitors = 500
40% screen 1
25% screen 2
rest screen 3
Process
1.- Calculate the 40% of 500
500 visitors ------------------- 100%
x ------------------- 40%
x = (40 x 500) / 100
x = 20000/100
x = 200 visitors
2.- Calculate the 25% of 500
500 visitors ------------------- 100%
x ------------------- 25%
x = (25 x 500) / 100
x = 12500/100
x = 125
3.- Calculate the number of visitors to screen 3
500 - 200 - 125
175
Answer:
1/16
Step-by-step explanation:
We know that a^ -b is equal to 1 / a^b
That means
4^-2 = 1/ 4^2 = 1/16
Answer: Experimental study
Step-by-step explanation:
This is an experimental study because it involves determination of the effect of each treatment on separate individuals. It involves selecting the 81 individuals randomly to be treated with a particular treatment (either of the two treatment). In experimental study the researcher apply separate treatments on a different groups and measure its effect on each of the groups.
Answer:
degree measure of arc AB = 120°
length of arc AB = 40π/3 in.
Step-by-step explanation:
arc AB has the same measure as its central angle. So, arc AB = 120°
120 is 1/3 of 360, Therefore, the length of arc AB is 1/3 of the circumference.
Therefore, the
length of arc AB = 1/3πd = 1/3π(40) =
= 40π/3 in.
