A.) write an equation in slope intercept form for the total cost of any number of tickets at 7 tickets for $5.
MrMuchimi
Slope intercept form is y = mx + b

7 tickets for $5 means that 1 ticket costs 5/7 dollars

So for part a, the slope intercept form would be:

y = \frac{5}{7}x

where x is the number of tickets, and y is the price.

For part b)

The slope intercept form is:
y = 25x

where x is the number of all you can ride wristbands you buy, and y is the total price.

What is the slope of the line that passes through the points (7,−4) and (7,0)?
GrogVix [38]

Answer:

undefined

Step-by-step explanation:

To find the slope given two points we can use

m = (y2-y10/(x2-x1)

   = (0 - -4)/(7-7)

    = (0+4)/(0)

    4/0

  This slope is undefined since we are dividing by 0

Q1 (a) A random variable X has the following probability function: Х O 1 2 3 4 5 and P(x) 0 k 2k 2k 3k 5k
gogolik [260]

Answer:

(i) It is known that the sum of probabilities of a probability distribution of random variables is one.

∴0+k+2k+3k+k

+k)=1

⇒10k

+9k−1=0

⇒(10k−1)(k+1)=0

⇒k=−1,

k=−1 is not possible as the probability of an event is never negative.

∴k=

(ii) P(X<3)=P(X=0)+P(X=1)+P(X=2)

=0+k+2k

=3k
