Given:
y varies directly with x
y = 8 when x = -6
what is the value of y when x = -2?
y = kx
we need to get the constant of variation.
8 = k(-6)
8/-6 = k
4/-3 = k or - 1 1/3
y = -4/3 (-2)
y = (-4*-2) / 3
y = 8 / 3
y = 2 2/3 OR 2.67
The correct answer is Choice B. y = -1.33x ; 2.67
Answer:11 hours
Step-by-step explanation:
you would add all three hours and then divide by 3 but first you would have to convert the minutes into hours so it would be 900/60 which is 15 so then you would do 8+10+15 / 3 which gives you 11
Answer:
what is the question
Step-by-step explanation:
Answer: 296
Step-by-step explanation:
Unique addresses (population size) = 1,346
Sample size = 50
Number of children - - - - - - - No of household
0 - - - - 5
1 - - - - 11
2 - - - -13
3 - - - - 10
4 - - - - 9
5 - - - - 2
Number of households with more than 3 children :
That is, households with 4 and 5 children
Total = 9 + 2 = 11 households
Therefore, proportion of households with more than 3 children :
(11 / sample size) × population size
(11 /50) × 1346 = 296.12
Approximately 296 households
