Answer:
Median: 178
Range:34
Step-by-step explanation:
To find the median, order the numbers from least to greatest:
162, 169,174, 177, 178. , 187, 192, 194, 196
Now, find the number in the middle:
178
To find the range, you subtract the greatest number (162) from the biggest number (196).

Answer:
- A) 290 km
- B) 4 hours
- C) 72.5 km/h
Step-by-step explanation:
Let distance be d and time t
<u>At 75 km/h speed the distance is</u>
- d = 75(t - 48 min) = 75(t - 48/60 hours)
<u>At 50 km/h speed the distance</u> is
<u>Since the distance is same, we get the equation:</u>
- 75(t - 48/60) = 50t + 40
- 75t - 75*4/5 = 50t + 40
- 75t - 60 = 50t + 40
- 75t - 50t = 40 + 60
- 25t = 100
- t = 4 hours
<u>A) The distance between A and B</u>
<u>B) Time is </u>
<u>C) The speed = d/t</u>
- Speed = 290/4 = 72.5 km/h
60 minutes = 54km/h
6 minutes = 5.4 km/h
24 minutes = 21.6 km
Answer:

Step-by-step explanation:
You can solve this two ways: insert the values into point-slope form and simplify to solve for y, converting it to slope-intercept form, <em>or</em><em> </em>insert the values into slope-intercept form, solve for b, and insert b. We'll do both :)
<em><u>Point-slope form:</u></em>

Where:
is the slope
and
are corresponding coordinate points 
Insert the given values:

Solve for y. Expand the right sie using the distributive property:

Isolate the variable. Subtract 6 from both sides, canceling out the 6 on the left:

<em>OR</em>
<em></em>
<em><u>Slope-intercept form:</u></em>

Where:
is the slope
is the y-intercept
and
are corresponding coordinate points 
Insert the given values:

Simplify the multiplication:

Solve for b. Add 10 to both sides, canceling out the 10 on the right:

The value of b is 4. Insert the appropriate information into the equation. When using slope-intercept form, you don't plug in the coordinate points:
