Y axis is counting by 2's
it started at 2 and went up to 6
Y = 4

X axis is counting by 2'2
starts at one goes to 3
X = 2

Slope is 4/2 because rise over run
4/2 = 2
Slope is simplified to 2.

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

Two positive, consecutive, odd integers have a product of 143. set up an equation to then solve for the integers.

mixer [17]

Answer:

Step-by-step explanation:

Let (2n-1) and (2n+1) be the consecutive, odd numbers.

(2n-1)(2n+1) = 143

4n² - 1 = 143

4n² = 144

n² = 36

n = 6

2n-1 = 11

2n+1 = 13

The numbers are 11 and 13.

Find the value of x

Sunny_sXe [5.5K]

Answer:

19.1

Step-by-step explanation:

Let's assign some variables to this triangle.

angle A = 63°

angle B = unknown

angle C = 71°

side a = 18

side b = y

side c = x

By the law of sins, applicable to ALL triangles, we have:

$\frac{sin(A)}{a} = \frac{sin(B)}{b} = \frac{sin(C)}{c}$

Let's then take the equation for angles A and C, in order to isolate the c (which is our x to find).

we then have

$c = \frac{sin(C) * a}{sin(A)} = \frac{sin(71) * 18}{sin(63)} = 19.10$

So, the answer is the second one.
