The % decrease in the number of scheduled passenger flights from February of 1999 to last February was 12.97%.

<h3><u>Percentages</u></h3>

Given that last February there were 617,624 scheduled passenger flights in a certain country, and in February of 1999 there were 709,639, to determine the % decrease in the number of scheduled passenger flights from February of 1999 to last February, the following calculation must be made:

  • 709639 = 100
  • 617624 = X
  • 617624 x 100 / 709639 = X
  • 61762400 / 709639 = X
  • 87.03 = X
  • 100 - 87.03 = X
  • 12.97 = X

Therefore, the % decrease in the number of scheduled passenger flights from February of 1999 to last February was 12.97%.

Evaluate the expression when q=5 and b=9.<br> a+4b
Ierofanga [76]

Step-by-step explanation:

a = 5

b= 9

a + 4b = ?

5 + 4×9 =

5 + 36 = 41

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

If f(x) = 9x – 8, which of the following is the inverse of f(x)?
zheka24 [161]

Answer: f^{-1} (x) = \frac{x+8}{9}

Step-by-step explanation:

f(x) = 9x - 8 , to find the inverse of f(x) , replace f(x) with y , then the equation becomes

y = 9x - 8 , then make x , the subject of the formula ,

9x = y + 8

x = \frac{y+8}{9}

Finally , replace x , with f^{-1} (x) and y with x  , so we have

f^{-1} (x) = \frac{x+8}{9}

The long-distance calls made by the employees of a company are normally distributed with a mean of 6.3 minutes and a standard de
Sergio [31]

To solve this problem, we use the formula:

z = (x – u) / s

where z is the z score value which can be obtained from the tables, x is the sample value, u is the mean = 6.3 min, and s is the std dev = 2.2 min

 

at P value = 0.90, the z = 1.28, finding for x:

x = z s + u

x = 1.28 * 2.2 + 6.3

x = 9.116

 

at P value = 1.0, the z = 3.49, finding for x:

x = z s + u

x = 3.49 * 2.2 + 6.3

x = 13.978 ~ 14

 

Therefore the longest 10% calls last about 9.1 minutes to 14 minutes
