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:
the qoustion is not correct
Answer:
31.1
Step-by-step explanation:
This is an isosceles triangle. Let us name the unnamed side y. y will also equal 22. We also know that this is a right triangle so using the pythagorean theorem we can calculate x. x = √(22^2+22^2) so x = 31.1.
<span>With 1026 being the mean score on the SAT and StDev of 209, Jessica has a score of 799/209 z-scores above the mean. Her z-score would be 3.823. The mean of the ACT and StDev are 20.8 and 4.8, respectively. A 28 ACT score would be 7.2/4.8 z-scores above the mean, for a z = 1.500. This means that Jessica has the higher z-score.</span>
