30/54 in simplest form is 5/9
Answer:
a. Mean
a. 79 points is an outlier, and the mean is most responsive to outliers.
Step-by-step explanation:
17, 14, 30, 24, 21, and 14
Let's calculate the measure of central tendency of the numbers first.
Mean = 120/6
Mean = 20
For Median
Let's arrange the numbers in ascending order
14,14,17,21,24,30
The median is 17 and 21
Median value =( 17+21)/2
Median = 38/2
Median = 19
Mode = 14.
After 79 was added.
Mean =( 120+79)/7
Mean = 199/7
28.43
For Median
14,14,17,21,24,30,79
Median= 21
Mode = 14
The value that changed the most was the mean value.
The answer to your question is A. rational numbers.
Rational numbers are closed under any set of operations.
Integers are not closed under division because 1/2 is not an integer.
The set {-1, 0, 1} is also not closed under division because -1/5 does not fall in that set.
Whole numbers are not closed under division because 5/3 will produce a number that is not a whole integer.
Your answer is A. rational numbers.
The blue line...
(1,2),(3,1)
slope = (1 - 2) / (3 - 1) = -1/2
there is a y int at (0,2.5) or (0,5/2)
it is shaded below the line....and it is a solid line
this inequality is :
y = -1/2x + 5/2
1/2x + y = 5/2
x + 2y = 5
x + 2y < = 5.....this is ur inequality
red line...
(0,4), (1,1)
slope = (1 - 4) / (1 - 0) = -3/1 = -3
there is a y int at (0,4)
it is shaded below the line...and it is a solid line
this inequality is :
y = -3x + 4
3x + y = 4
3x + y < = 4 ...this is ur inequality
summary :
ur 2 inequalities are :
x + 2y < = 5 and 3x + y < = 4
In the expression 4 to the power of 9, the number 9 is called the D. exponent.
Number four here is the base, and the exponent is always shown as a superscript to the right of the base. It shows how many times you are supposed to multiply the base by itself.
