Answer:

350 feet per minute

Step-by-step explanation:

The amount of time it took the plane to descend is 3 hours 14 minutes minus 1 hour 30 minutes.

This means it took 104 minutes for the plane to descend 36,400 feet.

Dividing 36400 by 104, you get 350 which is the average rate of descent in feet per minute.

Determine+the+percentile+indicating+the+bottom+ranking+20%.+in+other+words,+what+is+the+dollar+number+that+defines+where+the+low
Aloiza [94]

The dollar number that defines where the lowest values falls is

20% percentile value =$20

This is further explained below.

<h3 /><h3>What is the dollar number that defines where the lowest value falls?</h3>

Generally,  Now we need to determine the 20th percentile ($20). It indicates that we need to locate a dollar amount that marks the point at which the 20 % data has a value lower than that number.

i=(p/100)*n

Where i is the position of p^th

percentile when the data is presented in ascending order.

i=20/100*50

i=1000/100

i=10

Therefore

n=50

p=20

In conclusion, the 10th position for given data is 20,

Therefore, 20% percentile value =$20

Plz help asap for brainiest

Answer: x = 16

Step-by-step explanation:

If RQ is the bisector, that means the angle is cut in half. Therefore angles PRQ and QRS are equal to each other.

4x+6 = 7x-42

subtract 7x from both sides

-3x+6 = -42

subtract 6 from both sides

-3x = -48

divide both sides by -3

x = 16

The integers that make the linear equation false are:

3, 78, and 126

We found that by evaluating the equation in all the options.

<h3>Which integers make the equation false?</h3>

Here we have the linear equation:

8m - 15 = 5m + 63

And the possible solutions are:

S: {3, 26, 78, 126}

To see which of these integers make the equation false, we can replace the value of m by the given values and see when the equation is false (the number in the left is different to the one in the right).

if m = 3

8*3 - 15 = 5*3 + 63

9 = 78    this is false.

if m = 26

8*26 - 15 = 5*26 + 63

193 = 193  this is true.

if m = 78

8*78 - 15 = 5*78 + 63

609 = 453  this is false.

if m= 126

8*126 - 15  = 5*126 + 63

993 = 693  this is false.

So the integers that make the equation false are:

3, 78, and 126.
