Answer: 0.8313
Step-by-step explanation:
As per given we have,

Also, the distribution of the number of suitcases that get lost each week on a certain route is approximately normal.
Since , 
z-score corresponds to x= 10:
z-score corresponds to x= 20:
P-value = 

Hence, the probability that during a given week the airline will lose between 10 and 20 suitcases = 0.8313
Answer:
See Below
Step-by-step explanation:
(x-3)-2 ≤ 1 (x-3)-2 ≥ -1
+2 +2 +2 +2
x-3 ≤ 3 x-3 ≥ 1
+3 +3 +3 +3
x ≤ 6 and x ≥ 4
Answer:
55°
Step-by-step explanation:
Assuming you are looking for the angles and not the length of the sides, the remaining angle is 55°. All 3 angles have to equal 180°.
A+B+C=180
A+75+50=180
Subtract 75 and 50 from 180 to get:
A=55
Step-by-step explanation:
1. Distribute the -2. multiply-2 with 5x and 8. it will be -10x-16=14+6x. For me, i make small numbers negative or positive than big ones. Add 16 to both sides. it will be -10x=30+6x. Subtract 6x. -10x-6x=-16x. Divide both sides by 16. x=30/16= 1 and 14/16
