Step-by-step explanation:
<span>a. The number of cantaloupes sold at Central varied less than did the number sold at North.
</span>What is the MAD of the data set?
<span>{10, 9, 16, 5, 10}
</span>
mean = (10 + 9 + 16 + 5 + 10)/5 = 10
MAD = ( (10 - 10) + (10 - 9) + (16 - 10) + (10 - 5) + (10 - 10) )/5 = 12/5
The numbers of cubs in each litter were 1, 1, 2, 2, 3, 3, 3, 4, 5, and 6. The mean of these measurements is 3.
What is the mean absolute deviation?
mad = ( (3 - 1) + (3 - 1) + (3 - 2) + (3 - 2) + (4 - 3) + (5 - 3) + (6 - 3) )/10
a. 1.2
Tamar surveyed six friends, asking each how many times he or she had ridden in a helicopter. The numbers of times she recorded were 0, 0, 0, 1, 3, and 8.
What is the mean absolute deviation of the number of times? Round to the nearest tenth, if needed.
mean = (1+3+8)/6 = 2
mad = ( 2 + 2 + 2 + (2 - 1) + (3 - 2) + (8 - 2) )/6 = 14/6
c. 2.3 times
Four friends played cards. Their final scores were –6, –3, 0, and 1.
<span>What is the mean absolute deviation of their scores?
</span>
mean = (-6 - 3 - 1)/4= -10/4 = -2.5
mad = ( (6 - 2.5) + (3 - 2-5) + 2.5 + (2.5 + 1) )/2.5
mad = 4
Answer: (6, 7) x = 6
y = 7
Isolate x in the first equation.
2x = 12 Divide by 2 to both sides
x = 6 Isolated x!
Substitute in (6) for x in the second equation.
(6) - 5y = -29 Remove parenthesises
6 - 5y = -29 Subtract 6 from both sides
-5y = -35 Divide by -5 to both sides
y = 7 Isolated y!
With x = 6 and y = 7:
(6, 7)
Answer:idk
Step-by-step explanation:
Answer:
independent is miles, dependent is dollars
Step-by-step explanation:
y depends on x
x is always independent variable and y is dependent.
