Answer:
Mean=-21.5
Median=-26.5
Mode=-28
Range= -6 to-46
Step-by-step explanation:
Arranging the numbers given either in ascending or descending order. In this case, I used descending order as follows
-6
-11
-17
-25
-28
-28
-39
-46
Mode is the number that occurs more than others. In this case, only -28 appears twice hence it is the mode
The mean is given by adding all the numbers and dividing by the frequency.
The sum of numbers will be -6+-11+-17+-25+-28+-28+-39+-46=-172
Mean=-172/8=-21.5
The median is the number that appears in the middle after arranging the numbers in descending order as above. In this case, two numbers appear in the middle, that is -25 and -28 hence median -25+-28/2=-26.5
The range of numbers id from -6 to-46 as arranged above
Answer:
3/4 inches
Step-by-step explanation:
Subtract Jimmys string length from Sam's string length
7 1/2 - 6 3/4
Get a common denominator of 4
7 1/2*2/2 - 6 3/4
7 2/4 - 6 3/4
Borrow 1 ( or 4/4) from the 7
6 4/4 + 2/4 - 6 3/4
6 6/4 - 6 3/4
3/4

Answer:
y = 6/5
Step-by-step explanation:
3x - 5y = -3
Let x =1
3(1) - 5y = -3
3-5y = -3
Subtract 3 from each side
3-3-5y = -3-3
-5y = -6
Divide each side by -5
-5y/-5 = -6/-5
y = 6/5
