Answer:
58. 2 real roots; see attached for a graph
59. -6, 3
Step-by-step explanation:
58. A graphing calculator graphs this easily. The graph is shown in the attachment. There are 2 x-intercepts, hence 2 real roots.
__
59. The x-intercepts are (-6, 0) and (3, 0), so the x-values x=-6 and x=3 satisfy the equation y = 0.

Answer:
No
Step-by-step explanation:
Write the ratios of erasers to cost (dropping the dollar sign) as fractions:
(number of erasers)/(price): 2/1 and 10/4
The question is if the ratios 2/1 and 10/4 are equivalent.
2/1 = 2
10/4 = 2.5
A proportion is setting two ratios equal. Here, one ratio equals 2, and one ratio equals 2.5.
Since the ratios are not equivalent, the relation is not proportional.

Answer: The correct answer is option D: What is the height of the tallest player on a team?
Step-by-step explanation: In statistics generally, you deal with collection of data among other things. In collecting data, for the purpose of arranging and analyzing, you would need to collect data that can be varied, because the variability of the data collected would help in making an analyses that can be used for other similar data. So asking for someone's name for example is not a statistical question, because the answer is as simple as "My name is Brainly."
Hence, asking for someone's favorite color is not a statistical question. The answer is simple and does not require collecting different sets of data.
Asking for the total number of eggs in 5 dozen is a not statistical question because we already know the answer and there is no variability of the data that would be presented in the answer. Each dozen contains the same number of eggs. So its as good as asking what is the total number of eggs in a dozen, or in 10 dozens, and so on.
The total number of ounces in a gallon is also not a statistical question, because just like in option B above, there is no variability of the data that would be collected. The answer is pretty straight forward and that is 128 ounces (of liquid/fluid). There is no variability that would now give rise to analyses of data.
The height of the tallest player on a team is definitely a statistical question, because, <u>there are several players on a team, and their heights normally cannot be same</u>. So asking for the height of the tallest player simply implies that some are taller than the others, and at least one player is taller than all other players. So there will be variability of data in this particular instance, and the data analyst would have different sets of data (players' heights) available to him/her which can be used to draw conclusions
