Answer:
<em>a Inferential statistics</em>
Step-by-step explanation:
Inferential statistics are among the two central statistics categories.
<em>To define and draw conclusions about the population, inferential statistics use a random sample of data gathered from a population.</em>
Inferential statistics are useful when it is not feasible or practical to analyze every member of a whole population.
The absolute value of 19 is 19
A + (-7) = -17
a + (-7) + 7 = -17 + 7
a = -10
Its impossible to draw a trapezoid with just three right angles.
a trapezoid has 4 sides, which means all the angles inside the trapezoid must add up to 360 degrees.
if you have just 3 right angles (90x3), you already use up 270 degrees. Leaving you with just 90 degrees left, which is also a right angle. That means, there has to be four, if you have at least 3.
Answer:
a(n) = 20*2.5^(n - 1)
Step-by-step explanation:
Note that 50 is 2.5 times 20, and that 125 is 2.5 times 50. Thus the common factor is 2.5. The formula for the nth term is
a(n) = a(1)*r^(n - 1) => a(n) = 20*2.5^(n - 1)
