Statistic because it’s a fact and data that is being study as you go to school by the large quality of numerical data
1) Given equation: x/5 + 9 = 11
2) Subtract from both sides of the equation 9 (use Subtraction Property of Equality):
x/5+9-9=11-9,
x/5=2.
3) Unknown variable is dividend, 5 is divisor and 2 is quotient. To find unknown dividend you should find the product of divisor and quotient or in another words use the Multiplication Property of Equality:
x=5·2,
x=10.
These three consecutive steps show you that correct choice is B.
Answer: correct choice is B.
For the first question, we can extend all of the lines on the trapezoid, and triple the distance from B on the line, so we can use the fact that B is (2, 2), A is (0, 0), C is (4, 2), and D is (6, 0) to get that the new coordinates are A (-4, -4), B (2, 2), C (8, 2), and D (14, -4).
For the second question, notice that we are changing the size on the same line, and every side length is tripled by 3. If every side length is tripled by 3, then the perimeter of the new image is triple the perimeter of the original.
Answer:
a) x+3=19
Step-by-step explanation:
a)
x is the age of Ronald , Collin is three years older than Ronald , so if we add up x(Ronald's age) and 3(the difference between both of their ages), we would get Collin's age(19) . That is the explanation for this equation.
b)
x+3=19
x=19-3
x=16
thus , x is 16 , in other words , Ronald's age is 16.
Answer:
1st quartile: 1920s / 6
Step-by-step explanation:
First find the median, which is 1950s / 10. There are 5 rows behind it.
The median of those previous 5 rows is 1920s / 6.
