Since r = 2, and s = 7, we would substitute r and s with 2 and 7:

| r | - | s | = | 2 | - | 7 | = 2 - 7 = -5

The answer is -5

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

Trent writes p^2 + 30 = (p + 30)(p + 0)<br><br> Do you agree with Trent? Explain why

Bingel [31]

Answer:

Statement expressed by Trent is RIGHT.

$(p^2 + 30) = (p+30)(p +0)$

Step-by-step explanation:

Here, the given expression is:

( to show) : $(p^2 + 30) = (p+30)(p +0)$

Now, as we know by DISTRIBUTIVE PROPERTY:

A (B + C) = AB + AC

Consider the RHS of the expression:

(p +30)(p+0) = (p +30)(p) ............ ( a + 0 = a for all a)

Simplifying (p +30)(p) by distributive property, we get:

$(p +30)(p) = p(p) + 30(p) \\= p^2 + 30p\\\implies (p+30)(p+0) = p^2 + 30p$

⇒ Left side = Right side

Hence, statement expressed by Trent is RIGHT.

kifflom [539]

Answer:

D. Omar's transaction involves more money, because |-15| is greater than |10|.

Step-by-step explanation:

The absolute value of a number is simply the magnitude or numerical value of a number while ignoring any sign attached to it. For example, given that x is a real number, absolute value of x, |x| = x. The absolute value of x does not take account of any sign attached to it.

Thus:

The absolute value of Omar's transaction is given as |-15| = 15.

While that of Jake is |10| = 10.

15 is greater than 10.

Therefore, we can conclude that:

"Omar's transaction involves more money, because |-15| is greater than |10|."
