Answer:

A proportional relationship

y=3x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

we have the points

(1,3) ----> k=y/x ---->k=3/1=3

(2,6) ----> k=y/x ---->k=6/2=3

(3,9) ----> k=y/x ---->k=9/3=3

(4,12) ----> k=y/x ---->k=12/4=3

(5,15) ----> k=y/x ---->k=15/5==3

therefore

The relationship between the input (x) and the output (y) represent a proportional relationship

The constant of proportionality is equal to k=3

The equation is equal to

y=3x

The mean of the temperatures in the chart is 24° with standard deviation of 4°. How many years had temperatures within one stand
lions [1.4K]

Answer:

Step-by-step explanation:

Given: The mean of the temperatures in the chart is 24° and standard deviation is 4°.

To find: How many years had temperatures within one standard deviation of the mean

Solution: Mean temperature μ = 24 , standard deviation σ =4

The lower and upper bound for temperature within one standard deviation of the mean is given as:

Lower bound = μ - σ = 24 - 4=20

Thus, the Lower bound is = 20

Upper bound = μ + σ = 24+ 4=28

Thus, the Upper bound is = 28

Now, The temperature value between (Lower bound, Upper bound) that is (20, 28) is said to be within one standard deviation of the mean.

Hence 27° is the temperature value that is within one standard deviation of mean.

What is the ratio of 420m to 1 km
suter [353]

Answer:

21/50 or 21:50

Step-by-step explanation:

1km = 1000m

That means one meter is equal to 1/1000 of a km.

420 meters is 420/1000 of a km which is equal to 42/100 = 21/50 or 21:50

Is it right?
