Answer:
Relative frequency:
The most serious threat to aviation safety is, according to this data, "mechanical failures". It can be improved by more rigorous inspection and better maintenance policies and execution.
Step-by-step explanation:
We have the data for fatal plane crashes. The sum of plane crashes is
We can calculate the relative frequency as:
We can see that the most frequent cause is "mechanical problems", with a relative frequency of 0.45.
Answer:
x=117
Step-by-step explanation:
since there is 2 angles that they already give you the measurements with. you try to solve the 101 angle and subtract 180-101= 79. this is the angle beside 101. since a triangle is equal to 180 degrees; you add the 38 and 79 which equals 117. you subtract 180-117=63. That is the other angle on the inside of the triangle.
Answer:
8/17≤m≤8 ; [8/17, 8]
Step-by-step explanation:
To solve the inequality you need to isolate the variable in the middle of the inequality.
When you are solving the inequality each operation has to be done to every part of the inequality.
To isolate the m in the middle we need to divide each part by 17.
8≤17m≤136
8/ 17 ≤ 17m/ 17 ≤ 136/ 17
8/17≤m≤8
[8/17,8]
