Elenna [48]

<u><em>Answer:</em></u>

The slope of the line is 77

<u><em>Explanation:</em></u>

We know the speed is constant and that the mile-marker location over time can be represented by a line. This means that the equation is linear.

<u>The slope can, therefore, be calculated as follows:</u>

slope = \frac{y_2-y_1}{x_2-x_1}

where (x₁ , y₁) and (x₂ , y₂) are two points on the line

We are given that the two points (1, 123) and (3, 277) are two points in the line

<u>Substitute with them in the above equation to get the slope as follows:</u>

slope = \frac{277-123}{3-2}=77

Hope this helps :)

aleksandr82 [10.1K]

Answer:

27\leq x \leq37

Step-by-step explanation:

Let's arrange the numbers from least to greatest:

20, 25, 27, 28, 31, 32, 32, 38, 40, 40, 42, 48

The median is the "middle" number when arranged from least to greatest.

There are 12 numbers, so the middle number would be "average" of 6th and 7th terms.

6th term = 32

7th term = 32

Average = (32+32)/2 = 32

Hence, median = 32

Absolute deviation of 5 minutes means 5 minutes less or greater than the median, 32.

So, 32 - 5 = 27  &  32 + 5 = 37

Hence  27\leq x \leq37

3x = 180

X = 180/3 = 60°

the value of X is 60°
