Assume that you have an ordinary deck of 52 playing cards. How many possible 7- card pocker hands are there that contain at least one face card (Jack, Queen, or King)?

There are 115141000 possible ways.

Step-by-step explanation:

Since it is a 7 – card pocker hands, then the total number of poker hands will be:

Also, the total number of hands without figure cards is

This is because there are 12 cards with figures (4 x J, Q, K).

Therefore, the number of hands with at least one figure will be:

And this would be

133784560 – 18643560 = 115141000

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

you need to show the graph
