Answer:
x ≥ 5y
y ≤ 25
x ≤ 200
Step-by-step explanation:
It is given that Trisha wants to use at least 5 times as many key chains as thumb drives.
x represents the number of key chains and y represents the number of thumb drives.
Therefore, x ≥ 5y.
Total number of thumb drives is 25.
Therefore, y ≤ 25.
Total number of key chains is 200.
Therefore, x ≤ 200.
Well 25 seats are available so 25/250 equals 0.1 or
10%
You multiply by 2 because if you take any number let's say 15, 15x 6 is 90 1/3 of 90 is 30 and 15 is half of thirty. this works with all numbers so the answer is dilate by a scale factor of 2.

Answer:
The correct answer is - 97.74%.
Step-by-step explanation:
Given:
sample mean = 281
Std Dev = 47 ==> Sample
Std Dev (s) = std dev/sqrt(n) = 6.0677
Solution:
Find : P( x > 268 )
z = ( x - u )/s = ( 268 - 281 )/6.0677
= -1.9558
then, P( x > 270) = P( Z > -1.9558)
= P( Z <1.9558)
= 0.9747
change into percentage:
= 97.471%
