A shuttle operator has sold 20 tickets to ride the shuttle. All passengers (ticket holder) are independent of each other, and th

Rashid [163]

Answer:

a. Discrete probability distribution, frequent rider club, 0.65 of 20

b. 13

c. $60

d. $57.50

Step-by-step explanation:

a. X follows a discrete probability distribution because it involves discrete random variables which have probability mass function and frequency.

f(x) =0.65 of 20 passengers

b. if 0.65 0f 20 passengers are frequent riders,

then, the frequent riders will be 13 passengers

c. expected revenue will be $3 *20 passengers which will be $60.

the total number of passengers given tickets is 20 and the price for each is $3. thus, making the parameters to be price and number of passengers.

d. if the frequent riders are charged $2, then the amount paid by this group will be $2*13 which is $26

and if $4.50 is paid by the regular passengers it will be $4.50*(20-13) which is $31.50.

therefore, expected revenue will be $26+$31.50 equals $57.50

Please help me:(I’ll give you the brainliest

Answer:

The range of values for x is; 5 < x < 29

Step-by-step explanation:

The given parameters are;

$\overline {AB}$ = 15

$\overline {AD}$ = 18

$\overline {BC}$ = $\overline {CD}$ Given

$\overline {AC}$ = $\overline {AC}$ by reflexive property

∠BCA = 2·x - 10

∠DCA = 48°

Since 15 < 18, given the common sides of the tringle ΔABC and triangle ΔADC, angle ∡(2·x - 10)° < 48°

Therefore;

2x - 10 < 48

2·x < 48 + 10

∴ x < 29

Also, given that 2·x - 10 is real, 0 < 2·x - 10

10 < 2·x

10/2 < x

5 < x

Therefore, an acceptable range is 5 < x < 29

The temperature is -6º C (degrees Celsius) in southern Chile. It is 20º colder (less) in Antarctica. What is the temperature in

krok68 [10]

If you start from a temperature of -6° C and you need to lower that temperature of 20 more degrees, you have to subtract:

$-6-20 = -26$

So, the temperature in Antarctica is -26° C
