<span>Standard deviation shows the distribution present in a set. Range can be used to approximate this property.
Therefore, Set b (100, 140, 150, 160, 200 10, 50, 60, 70, 110) has the largest standard deviation because it has a range of 190 (i.e. 200 - 10)</span>
The function is degree 2 ( because of the x^2) so it is non-linear.
Plain : Spotted : Striped socks are in the ratio of 5 : 3 : 8
So we can say that number of plain socks = 5x
Number of spotted socks = 3x
Number of striped socks = 8x
Hence, total number of socks = 5x + 3x + 8x = 16x
⇒ Fraction of Striped Socks = 
⇒ Fraction of Striped Socks = 
⇒ Fraction of Striped Socks = 
Hence, of Alex's socks are striped
Answer:
$20
Step-by-step explanation:
Since we are talking about the unknown cost of a shirt AND a sweater, we are dealing with 2 unknowns. However, we can only have one unknown in a single equation or we cannot solve it. The cost of the sweater is based on the cost of the shirt, so the shirt will be our "main" unknown.
Cost of the shirt: x
Since the sweater is $5 more than (this is addition) twice (that is 2 times) the cost of the shirt, the expression for the sweater is 2x + 5
The cost of both is (equals) 65.
x + 2x + 5 = 65 and
3x + 5 = 65 and
3x = 60 so
x = 20
The shirt cost $20 so the sweater had to cost 65 - 20 = 45
The answer is Abecause if you plug in the value es for each function A is the only one the makes it trye
