Answer:

The given probability distribution is a discrete probability distribution.

Step-by-step explanation:

We are given the following in the question:

       x:    3        4        7

P(X=x): 0.19    0.3    0.51

Property of discrete probability distribution:

\displaystyle\sum P(x_i) = 1

If the given probability distribution satisfies this property then, it is a discrete probability distribution.

\displaystyle\sum P(x_i)\\\\= 0.19+0.3+0.51 \\= 1

Thus, it satisfies the property for a discrete probability distribution.

Thus, the given probability distribution is a discrete probability distribution.

The function f(x) = –x2 + 60x – 116 models the monthly profit, in dollars, a shop makes for repairing windshields, where x is th
Fynjy0 [20]
The function is: f ( x ) = - x² + 60 x - 116 is in the form: f ( x ) = a x² + b x + c
Part A:
x = -b / 2 a = - 60 / ( - 2 ) = 30
Then we will charge it into the function:
f ( 30 ) = - 30² + 60 · 30 - 116 = - 900 +1,800 - 116 = 784
The vertex is ( 30, 784 ).
It means that the maximum profit is $784, when 30 windshields are repaired.
Part B:
x 1/2 = ( -60 +/- √(3600 - 464 )/ (- 2 ) = ( -60 +/- 56 ) / ( - 2 )
x 1 = 2, x 2 = 58
It means that a shop has to repair at least 2 windshields and not more than 58 windshields for making a profit.

A new car has a sticker price of $22,150, while the invoice price paid on it was $18,780. what is the percent amount of markup?
Dmitrij [34]

The formula to find markup amount

\frac{Change in price }{original price}

A new car has a sticker price of $22,150, while the invoice price paid on it was $18,780.

Original price of new car = $18,780

Sticker price of new car = 22,150

Change in price = 22,150 - 18,780 = 3370

Markup = \frac{Change in price }{original price}

= \frac{3370 }{18780}

= 0.179446

Markup percentage = 0.179446 * 100 = 17.94%
