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
4x + 7x - 10x - 10 + 14 + 2
x + 6 is the simplified version of the equation.

Answer:
<em>90% confidence the Population mean number of texts per day</em>
(42.2561 ,47.1439)
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given sample size 'n' = 147
mean of the sample size x⁻ = 44.7
standard deviation of the sample 'S' = 17.9
<em>90% confidence the Population mean number of texts per day</em>

<u><em>Step(ii):-</em></u>
<em>Degrees of freedom </em>
<em> ν=n-1=147-1=146</em>
<em>t₀.₁₀ = 1.6554</em>


(44.7 - 2.4439 ,44.7 + 2.4439 )
(42.2561 ,47.1439)
<em><u>Conclusion:</u></em>-
<em>90% confidence the Population mean number of texts per day</em>
(42.2561 ,47.1439)
