-4x + 15 > 59
-4x > 44
x < -11 - switch the inequality when dividing or multiplying by a negative number
Answer: C. The measures of variation reveal nothing about the pattern over time.
Step-by-step explanation:
Given the following :
10 17 10 16 11 3 8 5 4 4 17 5 8 17
Range of hurricane data = 16
The standard deviation of sample data = 5.5 hurricanes
The variance of the sample data is 30.3 hurricane^2.
The measures of variation described above only shows the spread of the hurricane such as the range, that is the highest and lowest recorded.
The variance explains how spread out the data is and the standard deviation explains how values of a data differs from the mean value. The data fails to give time related information or pattern.
Answer:
b .
Area=(x-5) (x-3)
Area = x^2 -8x+15
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Area of a rectangle = width x length
The original length and width was x, so if the stage needs to be 5 feet narrower and 3 feet shorter.
x-5
x-5
The formula is:
A=(x-5) (x-3)
Solving:
A = (x.x) + (x.-3) + (-5.x)+ (-5.-3)
A = x^2 -3x -5x+15
A = x^2 -8x+15
