4. Tonya wants to place an advertisement in a local newspaper to sell her car. This piecewise function shows the cost of the advertisement given that x equals the number of lines.
c(x)
$22
=
122 + 3.5(x – 4)
x < 4
x>4
If the advertisement she wants to place will be 7 lines, how much will the paper charge her?
A. $32.50
B. $29.00
C. $26.50
D. $22.00

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

x = 3 ± √(5+y)

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
