GarryVolchara [31]
ABC airlines because it’s only 18 out of 126 “recent” flights which can only be greater than 13 percent of all of the time so you would have a less percent chance of your flight being delayed.

The distribution of annual profit at a chain of stores was approximately normal with mean \mu = \$66{,}000μ=$66,000mu, equals, d
Pepsi [2]

Answer:

The closest to the maximum profit is  x = \$ 83682

Step-by-step explanation:

From the question we are told that

  The  mean is  \mu  =  \$66,000

   The standard deviation is  \sigma  = \$ 21000

   The percentage of profit is  20%

Generally the closest to the maximum annual profit at a store where the executives conducted an audit is mathematically evaluated  as follows

     P(X >  x ) =  0.20

=>  P(X >  x ) = P(\frac{X -x}{\sigma }  >  \frac{x -66000}{21000} ) =  0.20

From the z-table  the z-score for  0.20  is  

    z-score =  0.842

So

     \frac{x -66000}{21000}  = 0.842

=>   x = \$ 83682

Perimeter and area of a rectangle 11 cm by 19.3cm
Dovator [93]

Answer:

Perimeter: 60.6cm

Area: 212.3cm

Step-by-step explanation:

When calulating the perimeter, you are adding the length of all the sides together. Since the figure is a rectangle, two two pairs of sides will be different lengths. Solving is as follows:

P= 11+11+19.3+19.3 or P=11(2)+19.3(2) =60.6

With area, you need the total amount of mass, so you would multiply two sides. In this case, the two are 11cm and 19.3cm.

A= 11(19.3)cm =212.3
