which set of ordered pairs represents a function? {(1, -9), (-5, -5), (1, -8), (-9, 5)}, { (3,6), (2, 1), (-8, 4), (2,0) }
Bezzdna [24]
Answer:
the answer is ((3,6),(2,1),(-8,4),(2,0)) because to be function the domin must not be the same
Answer:
Part A is 5/6 of the whole
Part B is 1/6 of the whole
Solution:
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 15 + 3 = 18
Part A = 15 and Part B = 3 are numerators for each fraction.
The fractions are then:
15/18 and 3/18
Meaning:
Part A is 15/18 of the whole
Part B is 3/18 of the whole
Reducing the fractions, it is also true that:
Part A = 5/6 of the whole
Part B = 1/6 of the whole
Answer:
The angles measure 34 degrees and 146 degrees.
Step-by-step explanation:
The supplement measures x.
The angle measures x + 112.
The measures of supplementary angles have a sum of 180 deg.
x + 112 + x = 180
2x + 112 = 180
2x = 68
x = 34
x + 112 = 146
The angles measure 34 degrees and 146 degrees.
It was reduced by $42.00 by the end of the seven weeks.
Answer: (72.535, 76.665)
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where 
= population standard deviation.
n= Sample size
= sample mean.
= Critical z-value (two-tailed)
Given : 
n= 81
The critical values for 90% confidence interval : 
Now, the confidence interval for population mean would be :
Hence, a 90 percent confidence interval estimatefor the average score of all students. : (72.535, 76.665)
