Why is this graph proportional?

Mathematics
1 answer:
Anastasy [175]2 years ago
8 0

Answer:

The graph represents a linear function that passes through the origin.

Step-by-step explanation:

Proportional functions can be represented by y=kx, where k is some constant. They form a straight line that always pass through the origin (0,0). We can see all these characteristics in the graph, thus the graph is proportional.

If you are good at sequences in math please help I am giving more points
Lunna [17]

Answer:

Graphs C and D show an arithmetic sequence.

Step-by-step explanation:

Arithmetic sequences have a common difference, meaning that the gap between each term in the sequence is always the same.

In Graphs A and B, the gap between terms seems to be changing. That tells us that they aren't arithmetic. Instead, those are geometric sequences.

Meanwhile, Graphs C and D appear to be straight, meaning that the gap between the terms is constant.

Lina20 [59]

Answer:

The estimated average electric cost amount of all residents in Las Cruces = 182.9

Step-by-step explanation:

The bill amounts from the electric company for the month of July for 10 randomly selected houses from the map was obtained to be

135 265 215 103 156 203 125 156 230 241

Using the Central Limit theory, the mean of a sample extracted randomly from an independent distribution is approximately equal to the population mean of the independent distribution.

This means that the sample mean of a random sample extracted from the population is a good estimate of the population mean.

Sample mean ≈ Population mean

μₓ = μ

Mean = = (Σx)/N

The mean is the sum of variables divided by the number of variables

x = each variable

N = Sample size = 10

Σx = (135+265+215+103+156+203+125+156+230+241) = 1,829

Sample mean = (1,829/10) = 182.9

Population mean ≈ sample mean

Population mean ≈ 182.9

Hope this Helps!!!
