For this you have to use the quadratic formula, do you know it?
Answer:
$3.25
Step-by-step explanation:
12c = 39
12/12 =0
39/12 = 3.25
c = 3.25
Answer:
9
Step-by-step explanation:
All u have to do is think only about two denominators, 9 and 3
And then memorize the multiplication of any number out of these two, until u get a number which is divisible by the other number. Its like,
9×1= 9
i
is it divisible by 3?
9/3= 3
Oh yes, it is divisible by 3 with no remainings. So that is the least common denominator
Answer:
see below
Step-by-step explanation:
A discriminant value of zero means there is exactly one x-intercept. The graph below has that characteristic.
_____
<em>Comment on discriminant</em>
discriminant > 0, two (2) x-intercepts (first 2 graphs)
discriminant < 0, no (0) x-intercepts (third graph)
Answer:
a number produced from a subset of the group of interest.
Step-by-step explanation:
This problems is, basically, about the difference of concepts between a statistic and a parameter.
When something is taken from a sample and estimated to the entire population, it is a statistic. For example, if you survey 200 Central New York residents, an 60% of them say they are Buffalo Bills fans, the 60% is a statistic.
When something is true to the entire population, it is a parameter. If i study the voting preference of all 53 players on the Buffalo Bills active roster, and 83% are Democrats, the 83% is an parameter.
So the correct answer is:
a number produced from a subset of the group of interest.
This subset is the sample, for example, and the group of interest is the population.
