Answer:
194 cents is the correct answer
Step-by-step explanation:
6.99 dollars is 41.94
For this case, we have that by definition, the proportions can be expressed in different ways. Example, if we have a dog and three cats:
75%: It's percentage
0.75: In decimal (75% are cats)
: In fraction. (There are of cats)
: Using ":" to separate sample values. (For every three cats there is a dog)
Care should be taken with the proportions, always multiplying the numbers in the proportion by the same value.

Answer:
a. 0.26
b. 0.7
c. 0.38
Step-by-step explanation:
For a)
For sponsored studies: 62 % found the products favorable. The percentage is 0.62.
For non-sponsored studies 46% found the products favorable. The percentage is 0.46
Total probability = P(A) × P (B)
= 0.46 × 0.62
= 0.2604
For b)
Probability for the food industry = 0.7
For c) 1 - ( 0.62) = 0.38

Answer:
Step-by-step explanation:
y = x^2 - x - 2 is a quadratic function. It's easily factorable: y = (x + 1)(x - 2). Setting this result equal to zero yields the x-intercepts: -1 and 2. This matches the x-intercepts shown on the graph.
The axis of symmetry, x = -b/(2a), derived from the coefficients 1, -1 and -2 of this particular function, is x = 1/2. This x = 1/2 is also the x-coordinate of the vertex. To find the y-coordinate of the vertex, we evaluate y = x^2 - x - 2 at x = 1/2, obtaining:
y = (1/2)^2 - (1/2) - 2, or y = 1/4 - 1/2 - 2, or -2 1/4. This does not quite agree with the y value (-2) shown in the diagram, but is close.
