Answer:
4) Yes
5) Yes
6) Yes
7) No
Step-by-step explanation:
4) When we look at the table in the question, we can see the pattern is comics x 3 = price.
We know the definition of a proportional relationship is when one number is increased, the other is as well. So, it is in a proportional relationship.
5) We do the same thing here, we notice that we can divide the number of bikes by 5 to get the number of trips.
So, this is a proportional relationship.
6) The same reasoning applies to 6, we can see they follow a pattern.
7) All of them can be multiplied by 2, except the last one can't, so this is NOT a proportional relationship.
24 second and 4 ounces
Step-by-step explanation:
The point where both lines meet is the point where are both equal
The point where both lines met is (24,4)
Since the x-axis represent second the y-coordinate will represent the number of second it takes for them to be equal to each, other which is 24
Since the Y-axis represents ounces the Y-coordinate will represent the number of ounces they have when they are equal ,which is 4.
And there is only one solution.
Answer:
1.3 pounds; on average, weight of a bag varies 1.3 pounds from the mean of 7 pounds
Step-by-step explanation:
the mean absolute deviation is 1.3 and the mean is 7. i just took this test today, hoped this helped:)
When x=5, f(g(x)) would be (x-1/4)^2 - 3(x-1/4) + 3 which when you plug 5 in for x, you get 11.3125 as an answer
