Let the 2 integers be
x and
y.
Their product is 72, so we write:
xy=72. (I)
One of them, say
y, is 2 less than 5 times the other. We can write this as the equation:
y=5x-2. (II)
To find one of numbers, say x, we can substitute y with 5x-2, in the first equation:
xy=72,
expanding the left hand side expression we get:
.

Answer:
4
Step-by-step explanation:
To find the side length of the original triangle:
24/3=8 (because it is an equilateral triangle).
Because the triangle is dilated by a factor of 0.5 and the triangle is equilateral, the side lengths of the new triangle is
8*0.5=4

Apart from negative numbers and 0 and 1, other whole numbers are fine
Answer: 9% parameter, 3% statistic
Step-by-step explanation: Parameter and statistic are are statistical terms used to describe a group or observation.
However, the distinction between a parameter and a statistic is in the measured observation.
Parameter is used to describe an entire population while statistic is used to describe a sample.
Where a population refers to the entire number of people or inhabitant of a particular country while a sample refers to a subset of observation drawn randomly from a population which serves a representative of the entire population.
In the question above, 9% is used to make a description of the whole American population who are at least 75 years of age. While,
3% is used to describe a subset of the American population (sample) who are 75 years or older.
