a) Write an equation for each music provider.

Results are below.

Step-by-step explanation:

Giving the following information:

iTones charges $10 per month, and $1 per song.

Music Mine charges $7 per month and $1.50 per song.

To calculate the total cost for each option, we need to use the following formulas:

iTones:

Total cost= 10 + 1x

x= number of songs

Music Mine:

Total cost= 7 + 1.5x

x= number of songs

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
