What is the best interpretation of the y-intercept of the line ?
RoseWind [281]

Answer:

Last option

Step-by-step explanation:

Notice that the y-axis represents test scores. The lowest value on the y-axis is a 60.

The x-axis represents hours studied. The lowest value on the x-axis is a 0.

This implies a student who would study 0 hours would expect to score a 60 on the test.

The circumference of circle P is 800 mm, the circumference of circle Q is 200 cm, and the circumference of circle R is 4 m. What
Lapatulllka [165]

Answer:

circle P has a circumference of 800mm which is equal to 80cm

circle Q is 200cm

circle R is 4m which is equal to 400cm

You will get the sum of the distances by placing the figures under one measurement that is meters

And so add the figures in cm(200+400+80) and get 680

Then convert this to meters and get 6.8m

Hence your answer is C

It takes the high-speed train x hours to travel the z miles from Town A to Town B at a constant rate, while it takes the regular
e-lub [12.9K]

Answer:

\Delta d =\frac{y-x}{y}*d_{Hs}\

Step-by-step explanation:

Fist the velocity of high-speed train will be given by:

V_{Hs} =\frac{z}{x}

And the velocity of the regular will be given by:

V_{R} =\frac{z}{y}

The position equations of each movement will be given by:

d_{Hs} =\frac{z}{x} t

d_{R} =z-\frac{z}{y} t

We can get the encounter point isolating t in the first equation and reepalcing it in the second one:

First isolating:

d_{Hs}\frac{x}{z} = t

Second reeplacing t:

d_{R} =z-\frac{z}{y}*d_{Hs}\frac{x}{z}

d_{R}=z-\frac{x}{y}*d_{Hs}\

In the  moment of the encounter the high-speed train have gone round  d_{Hs}\ and the regular one \frac{x}{y}*d_{Hs}\

Then the difference  between the distance traveled the high-speed train and the regular one is:

\Delta d =d_{Hs}-\frac{x}{y}*d_{Hs}\

\Delta d =\frac{y-x}{y}*d_{Hs}\
