Answer:
1. Median = 10.1
2. A. The median represents the center.
3. D. The mode(s) can't represent the center because it (they) is(are) not a data value.
Step-by-step explanation:
Mean of a sample = sum of the samples/no of the samples
Samples in increasing order:
9.8
9.8
9.9
10.1
10.4
10.6
11.1
Mode is the sample with highest frequency.
Median is the middle entry of the data.
Mean = (9.8 + 9.8 + 9.9 + 10.1 + 10.4 + 10.6 + 11.1)/7
= 717/7
= 10.243
Median = 10.1
Mode = 9.8 because it has the highest frequency of 2
3280.839895 ft = 1 km
60 ft = 60/3280.839895 = 0.018288 km
60 ft/s = 0.018288 km/s = 0.018288 x 60 x 60 = 65.8368 km/h
Answer:
2 wholes and 5/26
Step-by-step explanation:
convert the mixed number to improper fraction
= -19/6 / -13/9
since there is 2 negatives and (-)/ (-) means your answer is positve
to divide by a fraction multiply by the reciprocal of that fraction.
19/6 x 9/13
reduce 6 and 9 to 3 and 2 becuase both have a GCF of 3.
19/2 x 3/13
multiply 19/2 x 3/13
= 57/26
= 2 wholes and 5/26
= 2.1923076
First simplify the equation.
3x+3y= -x+5y
4x=2y
2x=y
y=2x
Means that the y value is 2 times the x value.
answer: C but there are more solutions than just (1,2) and (2,4)
