Answer:

See Below

Step-by-step explanation:

I'm not going to do the homework for you, but I will complete three of the problems to help you understand the process.

We are converting between different units of measurement.

Here are the conversions to know:

12 inches = 1 foot

3 feet = 1 yard

1760 yard = 1 mile

5280 feet = 1 mile

We need to convert 7 feet into inches.

7 feet * 12 inches per foot = 84 inches

Now we know:

84 inches = 7 feet

What's the difference is between 84 inches, and 18 inches?

84 inches - 18 inches = 66 inches

We need 66 more inches to get a length of 7 feet.

We need to convert 2 miles into yards.

2 miles * 1760 yards per mile = 3520 yards.

Now we know:

3520 yards = 2 miles

What's the difference between 3520 yards and 2000 yards?

3520 yards - 2000 yards = 1520 yards

We need 1520 more yards to make 2 miles

We need to convert 108 inches into feet.

108 inches / 12 inches per foot = 9 feet

Since there is no remainder,

9 feet = 108 inches.

Hopefully you can see what is going on here and do the rest yourself.

The formula y = mx + b sometimes appears with

different symbols.

For example, instead of x, we could use the

letter C. Instead of y, we could use the letter F.

Then the equation becomes

F = mC + b.

All temperature scales are related by linear

equations. For example, the temperature in

degrees Fahrenheit is a linear function of degrees Celsius.

Water freezes at: 0°C, 32°F

Water Boils at: 100°C, 212°F

Hope this helps!

What would be the steps for finding the equation for the function f(x) based on the graph (the blue line) and what would the equ

sattari [20]

Answer:

f(x) = -2|x-2| +4

Step-by-step explanation:

Step 1: recognize this as an inverted, scaled, and translated absolute value function.

Step 2: identify the scale factor as 2, because each section has a "rise" of 2 for each "run" of 1. The scale factor is -2 because the function is inverted (reflected across the x-axis).

Step 3: identify the vertex* as (2, 4).

Step 4: Use the scale factor and translation information to make the transformation ... (let abs(x) represent the absolute value function)

f(x) = (scale factor)×abs(x -horizontal shift) + (vertical shift)

f(x) = -2|x -2| +4

_____

* The vertex is an identifiable point on the graph of this function. Knowing how the vertex is translated tells you how the whole function is translated. In general, you want to use an identifiable point (a turning point, point of symmetry, extreme point, whatever) when you're trying to determine the translation. For some functions, like a line, there is no specific identifiable point, so determining any specific translation is difficult or impossible.

_____

Comment on writing functions from graphs

One of the reasons for studying different functions is so you can learn to recognize their shape, and associate a formula and certain properties with that shape.

_____

The attached graph shows the parent absolute value function in blue and the transformed function f(x) in red.

Consider the game where two dice, die A and die B, are rolled. We say that die A wins, and write A > B, if the outcome of rol

In-s [12.5K]

Answer:

a) The probability of a tie is the probability of getting the same outcome in both dice.

First, we roll die A and we get a given outcome. (here the probability is 1 because there is no restriction)

Now we need to roll die B and get the same outcome, so here we have only one possible outcome out of 6, then in this case the probability is 1/6

The joint probability (the product of the individual probabilities) is: P = 1*(1/6) = 1/6

b) We want to find the probability that die A wins.

Here we need to analyze each possible outcome for die A.

Let's define:

pₙ = probability of winning given that the outcome is n.

If the outcome is a 1, die A can only lose or tie, then here:

p₁ = 0

If the outcome is a 2, then die A only wins if die B rolls a 1, (1 outcome out of 6)

Then the probability of winning is:

p₂ = 1/6

If the outcome is a 3, then die A wins if die B rolls a 1 or a 2, here we have two possible outcomes out of 6.

p₃ = 2/6

We already can see the pattern, if the outcome is a 4, we get:

p₄ = 3/6

if the outcome is a 5:

p₅ = 4/6

if the outcome is a 6:

p₆ = 5/6

The total probability is the sum of all the joint probabilities:

For each roll in dice A, the probability is 1/6 (the probability of getting a given outcome)

Then the probability that die A wins is:

P = (1/6)*p₁ + (1/6)*p₂ + ... = (1/6)*(p₁ + p₂ + p₃ + p₄ + p₅ + p₆)

P = (1/6)*(0 + 1/6 + 2/6 + 3/6 + 4/6 + 5/6)

P = (1/6)*(15/6) = 0.4167
