Step-by-step explanation:
-4x<_-23-9
-4x<_-32
x>_-32/-4
x>_8
x=[8,positive infinity )
standard form.
2+3x+4x2+3x3 is 2+3+8+9
Step-by-step explanation:
you have to result the multiple firt and then to add the rest operation.
the result of the operation is 57
1/4*13=3.25 gallons
2.50*4=10
3.25+4=7.25
The answer is 7.25 gallons
Answer:
The Interquartile range is 188
Step-by-step explanation:
Missing Data:
1,19,35,43,49,55,63,94,105,110,175,231,239,351,738
Required
Determine the Interquartile range (IQR)
The given data is ordered already.
First, we need to determine the median
For odd number of data
Median = ½(n + 1)th
In this case, n = 15; so
Median = ½(15 + 1)th
Median = ½(16)th
Median = 8th
This implies that the median is at the 8th position.
So, we have:
1,19,35,43,49,55,63 ----> Lower
(94) ---- Median
105,110,175,231,239,351,738 ---- Upper
Next, we determine the median of the lower and upper sets.
These are called lower quartile (Q1) and upper quartile (Q3) respectively
Lower: 1,19,35,43,49,55,63
Number of data, n = 7
Q1 = ½(n + 1)th
Q1 = ½(7 + 1)th
Q1 = ½(8)th
Q1 = 4th position
From the list of data in the lower set,
Q1 = 43
Upper: 105,110,175,231,239,351,738
Number of data, n = 7
Q3 = ½(n + 1)th
Q3 = ½(7 + 1)th
Q3 = ½(8)th
Q3 = 4th position
From the list of data in the upper set,
Q3 = 231
IQR is then calculated as thus:
IQR = Q3 - Q1
IQR = 231 - 43
IQR = 188
1/4 are female
How many of the adults are female?
The equation that describes the line that contains (1,5) and has a slope of 2 is y = 3x + 2
The equation of a line in point slope form is expressed as;
Given the following parameters;
Slope = 2
Point on the line is (1, 5)
Substitute the given parameters into the formula to have:
y - 5 = 3(x-1)
y - 5 = 3x - 3
y = 3x + 2
Hence the equation that describes the line that contains (1,5) and has a slope of 2 is y = 3x + 2
