Acruise ship needs to book at least 2,052 passengers to be profitable, but the most passengers the ship can accommodate is 2,462. model the numbers of passengers that need to be booked to ensure the cruise line makes a profit, using a compound inequality.
x ≤ 2,052 and x ≥ 2,462
x ≥ 2,052 and x ≤ 2,462
x ≤ 2,052 and x ≤ 2,462
x ≥ 2,052 and x ≥ 2,462

Step-by-step explanation:

Given : A cruise ship needs to book at least (more than or equals to) 2,052 passengers to be profitable, but the most (less than or equals to) passengers the ship can accommodate is 2,462.

Let x denotes the accommodate is 2,462. Model the numbers of passengers that need to be booked to ensure the cruise line makes a profit.

Then , we have the following compound inequality :-

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
