Your answer is x=-1 y=1. Have a great day:)
I can't be sure but I think the answer is A. $78.75.
Step-by-step explanation:
consider k the numbe of correct answers
P(k) = kC8×(0,2)^k×(0,8)^(8-k)
example:
The probability of having 2 correct answers = 2C8×(0,2)^2×(0,8)^(6) = 0.294
the probability that the number x or correct answer is fewer than 4 =
p(0) + p(1) + p(2) + p(3) = 0.944
The data in the table represents a <span>C. exponential function. In an exponential function, as x-values increase, y-values get greater and greater. The y-values increase more rapidly as x-values increase linearly.</span>
