Answer:
2.5
Step-by-step explanation:
5x+3x=20
8x=20
x=20/8=2.5
Answer:
As the givens set A contains 24 elements.
Therefore,
The Cardinality of the set A = 24
Step-by-step explanation:
Let the given set is A
A = {x: x is a positive counting number less 25}
The set of natural numbers is often termed as the Counting number set.
-
As the counting numbers are less than 25.
Thus,
Set A will be:
<u>The Cardinality of the set</u>
The Cardinality of the set represents the total number of elements in a given set.
As the givens set A contains 24 elements.
Therefore,
The Cardinality of the set A = 24
Answer:
Area = 139.27 m²
Step-by-step explanation:
Area of the composite figure = area of rectangle + area of semicircle
= (L*W) + ½(πr²)
L = 10 m
W = 10 m
r = ½ of 10 = 5 m
Plug in the values
Area = (10*10) + ½(π*5²)
Area = 100 + 39.27
Area = 139.27 m²
Data:
15 16 14 15 19 17
n=6 points
sum is 96
mean is 96/6 = 16
Now we look at the absolute deviations, each of which is the absolute value of a score minus the mean, basically the distance of the score to the mean .
Scores 15 16 14 15 19 17
AbsDev 1 0 2 1 3 1
The sum of the absolute deviations is 8 and there are six of them so the
Mean Absolute Deviation = 8/6 = 4/3
Answer: 2. 8/6
