A website-hosting service charges businesses a one time setup fee of $75 plus $15 for each month. If a business owner paid $1,000 for the first m months, which of the following equations models this situation ?
75 + 1000 = 15m
15 + 75m = 1000
75+ 15 = 1000
m
15m + 75 = 1000

Will mark brainliest if you answer ! the taco shop sold 198 lunches friday. this number is 3 more than 3 times the number they sold monday. let n represent the number of lunches sold monday. which equation shows an equality between two different ways of expressing the number of lunches sold on friday? a. n – 3 = 198 b. 3n – 3 = 198 c. 3n + 3 = 198 d. n + 3 = 198

Before simplifying, how many terms are there in the expression 2x - 5y + 3 + x?

The discrete random variables x and y take integer values with joint probability distribution given by f (x,y) = a(y−x+1) 0 ≤ x ≤ y ≤ 2 or =0 otherwise, where a is a constant. 1 tabulate the distribution and show that a = 0.1.2 find the marginal distributions of x and y. 3 calculate cov(x,y).4 state, giving a reason, whether x and y are independent. 5 calculate e(y|x = 1).
