Four-ninths of a drink mix is dye and the rest is pure ugar. When the mix is added to water a gallon of the drink is made that is 7.5% sugar. What percentage of the gallon is dye?
A bag contains 50 tickets numbered 1, 2, 3, 4.....50 of which five are drawn at random and are arranged in ascending order of magnitude. Find the probability that third drawn ticket is equal to 30.
In the function above, if f(k) = 2, then which one of the following could be a value of k?
(A) –1
(B) 0
(C) 0.5
(D) 2.5
(E) 4
f(k)=2
On the graph, that would mean the x is k and the y is2
In the first quadrant when y = 2 the value for x could be from anywhere from roughly 1.75 to 3.5.
None of the answer choices are ranges but D is within our range. And since the question asks what value “could be” k, that must be the answer.
D.
