Answer:

-5/7

Step-by-step explanation:

Finding slope from 2 points is found using this format: y-y1/x-x1. Plug in your points to the expression to get: -1-4/4--3. -1 -4= -5, and 4--3 = 7. So, the slope is -5/7. Hope this helps!

What is the slope of (5,7) and (-2,0)

yulyashka [42]

Answer:

Slope: 1

Step-by-step explanation:

In this question, we need to find the slope with the given points.

To find the slope, we would use the equation:

m = y2-y1/x2-x1

Plug in your coordinates and solve:

m = 0 - 7/-2 - 5

m = -7/-7

Two negatives cancel each other to make a positive, and 7/7 = 1

m = 1

This means that the slope would be 1.

Among fatal plane crashes that occurred during the past 55 years, 415 were due to pilot error, 96 were due to other human err

azamat

Answer:

Relative frequency:

$\text{Pilot error}=415/1370=0.30\\\\\text{Other human error}=96/1370=0.07\\\\\text{Weather}=169/1370=0.12\\\\\text{Mechanical problems}=622/1370=0.45\\\\\text{Sabotage}=68/1370=0.05\\\\$

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:

$\text{Pilot error}=415/1370=0.30\\\\\text{Other human error}=96/1370=0.07\\\\\text{Weather}=169/1370=0.12\\\\\text{Mechanical problems}=622/1370=0.45\\\\\text{Sabotage}=68/1370=0.05\\\\$

We can see that the most frequent cause is "mechanical problems", with a relative frequency of 0.45.
