Answer:
3.6 qt. and 2.4 qt respectively
Step-by-step explanation:
Let x be x% of 50% saline solution. And (100-x%) be the percentage of 60% saline solution.
54=x*(50/100)+(100-x)*(60/100), solving it we will get x=60%. So we need 3.6 qt. of 50% saline solution and 2.4 qt. of 60% saline solution
Answer:
2800m
Step-by-step explanation:
Assumption:
Start point from which Percy Cod walks is "x"
If he walks around a perimeter that is the shape of a rectangle,
Length of area = L = 1000m
Width of area = W = 400m
Distance around the rectangle = D = 2 * (L + W)
D = 2 * (400+1000)
D = 2 * 1400
D = 2800m
Yes it is possible. Consider the following scenarios
Scenario A:
Min = 5
Q1 = 10
Median = 12
Q3 = 18
Max = 22
The IQR is equal to the difference of Q3 and Q1
IQR = Q3-Q1 = 18-10 = 8
The range is the difference of the min and max
Range = Max - Min = 22 - 5 = 17
So in summary for scenario A, we have
IQR = 8
Range = 17
----------------------------------------------------------
Now consider another scenario, call it scenario B, where
Min = 100
Q1 = 102
Median = 105
Q3 = 110
Max = 117
I claim that the IQR and Range for scenario B is going to be the same as in Scenario A. Let's find out
IQR = Q3 - Q1 = 110 - 102 = 8
Range = Max - Min = 117 - 100 = 17
So
IQR = 8
Range = 17
which is identical to scenario A.
-------------------------------------------------------------------------------
Scenario B has completely different data than scenario A, yet the IQR and Range are equal to scenario A's counterparts. This shows that it is possible to have 2 completely sets of data yet have the same IQR and range.
The wrap up here, and the answer to the question, is "yes it is possible" with the explanation given above.
Answer:
Option D
Step-by-step explanation:
Increasing intervals represent the inputs that make the graph rise, or the intervals where the function has a positive slope. Decreasing intervals represent
the inputs that make the graph fall, or the intervals where the function has a negative slope.
The inputs ( − values) that make () rise are
(-2,∞)
