Answer:

a. 0.1\ miles

b Slope: \frac{1}{10} or 0.1

Step-by-step explanation:

The equation of a line that passes through the origin is:

y=mx

Where "m" is the slope of the line.

By definition, Direct variation equations have the following form:

y=kx

Where "k" is the Constant of variation.

Then, you can conclude that:

m=k

a. Let be "d" the distance in miles that the train travels per gallon.

You can observe in the graph that when the train travels 10 miles, it uses 100 gallons. Then, you can set up the following proportion:

\frac{10}{100}=\frac{x}{1}

Solving for "x", you get:

x=\frac{1}{10}\\\\x=0.1

Then, it travels 0.1 miles per gallon.

b. The slope is also \frac{1}{10} or 0.1. To check this, you can subsitute the coordinates of the point (100,10) into y=mx and solve for "m" in order to find its value.

This is:

10=m(100)\\\\m=\frac{1}{10}

An ice chest contains 3 types of drinks: 10 apple juries 15 grape juices and 15 bottles of water what is the probability of gett
Anna [14]

Answer: \dfrac{3}{8}

Step-by-step explanation:

Given: An ice chest contains 3 types of drinks: 10 apple juries 15 grape juices and 15 bottles of water.

Total drinks= 10+15+15 = 40  (Total outcomes)

Number of drink that does not contain fruit juice = Number of bottles of water = 15  (Favorable outcomes)

The probability of getting a drink that does not contain fruit juice = \dfrac{Favorable\ outxcomes}{Total\ outcomes}

=\dfrac{15}{40}\\\\=\dfrac{3}{8}

So, the required probability = \dfrac{3}{8} .

The operation * on the set Z of integers is defined by x*y = 3x + 2y - 1, x, y E Z. Find the value of x such that x*2=5​
Assoli18 [71]

Answer:

x = 2/3

Step-by-step explanation:

Let's unpack the equation x*2=5 from our definition of *:

x*2=3x+2(2)-1=5 (where x\in \mathbb{Z})

Now that we've got things defined in terms of familiar operations, we can simplify and solve for x:

3x+2(2)-1=5\\3x+4-1=5\\3x+3=5\\3x=2\\x=2/3
