Step-by-step explanation:

A = 6b ( divide both sides by 6 )

\(\frac{A}{6}\) = b

--------------------------------------

A = \(\frac{1}{2}\) bh ( multiply both sides by 2 to clear the fraction )

2A = bh ( divide both sides by h )

\(\frac{2A}{h}\) = b

I dont know if you want me to draw it but try drawing the first line for pusheen a little bit up but more to the right because she only went out the door. Next for her you want to make the line go straight to the right for a bit to say she tripped. Then have the line slowly rise because she is walking away from home not running anymore. Then stall it for the rest of the way.

Now lets start for terrence draw his line going up rapidly. Then start to lower the line bit by bit to show he slowed down going up the hill. For his it never stops so never make the line straight to the right for him.

This should be all hope this helps.

Answer:

The first image is for question 1, the second image is for question 2.

Step-by-step explanation:

Alright, let's say for #1 each little tic I drew on the x-axis and y-axis of the graph are intervals. Let's say for time, each tic is an interval of five seconds, and for distance from home, each tic is an interval of a few feet - maybe 3-5.

For #1, Pusheen runs a few feet from her house (running out of her front door signifies that) in around 10 seconds. Then, she falls. Let's assume it takes her another 10 or so seconds to get up. During that time, she doesn't move from the spot where she fell, but time continues, so x increases while y doesn't. Afterwards, she gets up and walks down the block. As she's walking, let's estimate that she goes about 10 feet within 20 seconds.

Boom. Question 1 is done.

Now, let's say for #2 each little tic I drew on the axes of the graph are intervals. Let's say for time, each tic is, once again, an interval of five seconds, and for distance from home, each tic is now an interval of 10 feet.

For #2, Terrence cycles down a hill from his house. (Basically, he rides a bicycle down from his house on the hill.) He's rapidly cycling, zooming down the hill pretty quickly. Let's say he moves a decent 30 feet in around 20 or so seconds. Not too bad. Afterwards, he slows down as he begins to climb the other side, presumably the other side of the hill, to reach the candy shop. Now, he's moving slower and climbing. Suddenly, he's only moving a few feet for every 5 seconds that passes.

Boom. Question 2 is done.

The image of point (-3,-2) under the same translation is the point (-1, -8).

A translation is a geometric change in Euclidean geometry that involves moving each point in a figure, shape, or space by the same amount in one direction. A translation may alternatively be thought of as moving the origin of the coordinate system or as adding a constant vector to each point.

Given;

The image of the origin under a certain translation is the point (2,-6).

To find the translation:

The translation rule can be expressed as;

(x, y) → (x + a, y + b),

where a =x₂ -x₁,

the number of units the center needs to be moved in the x -direction

and  b = y₂ -y₁,

the number of units the center needs to be moved in the y -direction.

The point is given as (0, 0)

The image of the point is (2, -6).

So,

(x, y) → (x + a, y + b),

Substituting the points,

(x, y) → (x +(2-0), y +(-6-0)),

(x, y) → (x +2, y -6).

So, the image of point (-3,-2) under the same translation is the point:

(x +2, y -6) → (-3 +2, -2 -6)

(x +2, y -6) → (-1, -8)

Therefore, the image of the translation is (-1, -8).

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let x, y, z represent the numbers of 1-, 2-, and 3-point baskets, respectively. The given relations are ...

  x +2y +3z = 31 . . . . . . total points scored

  y -x = 5 . . . . . . . . . . . 5 more 2-point baskets than free throws

  y = 3z . . . . . . . . . . . . 3 times as many 2-point baskets as 3-point baskets

Using the second equation to write an expression for x, we have ...

  x = y -5

Substituting this and the third equation into the first, we get ...

  (y -5) +2y +(y) = 31

  4y = 36 . . . . . . . . . . . add 5, collect terms

  y = 9

Step-by-step explanation:

Step-by-step explanation:

first fill out the bracket

-7*8x = -56x

-7*-3 = 21

So the equation is now

-56x+21< 133

Now transpose to get -56x by itself

-56x+21 -21< 133-21

-56x< 112

Then transpose to get x by itself

-56x/-56< 112/-56

Therefore

x< -2

The slope of a regression line provides valuable insights into the relationship between two variables in a linear regression analysis. It represents the rate of change in the dependent variable for a one-unit increase in the independent variable.

Specifically, a positive slope indicates that as the independent variable increases, the dependent variable also tends to increase. Conversely, a negative slope suggests an inverse relationship where an increase in the independent variable corresponds to a decrease in the dependent variable.

The magnitude of the slope is crucial as it quantifies the strength of the relationship. A larger slope signifies a steeper incline or decline, indicating a stronger association between the variables. Additionally, the slope can be interpreted as the predicted change in the dependent variable when the independent variable increases by one unit, assuming all other variables remain constant.

Overall, the slope of the regression line serves as a crucial indicator of the direction, strength, and magnitude of the relationship between variables in a linear regression model.

Five to the seven thirds power is the correct answer. This expression can be rewritten as the cube root of five to the seventh power, which is equal to five to the seven-thirds power.

When a term is multiplied by itself several times, it is said to have "power" or exponents in mathematics. An exponent, which is expressed as a little number above and to the right of the base number, serves as a representation for this. For instance, the number 2 to the power of 3 (23) is represented as 222 and equals 8.Power can alternatively be written as xy, in which x is the base number and y is the exponent. The equation 23 is represented as 23 in this notation, and it still equals 8.Power, in addition to representing repeated multiplication, may also be used to indicate a number's root.

The expected value (EV) of betting $3 on red is -$0.16

The standard deviation (SD) of betting $3 on red is 2.995

The expected value of the bet is calculated as follows:

there are 18 red slots out of 38 total, so the probability of winning a bet on red is 18/38, or 0.4737.

The probability of losing the bet is 1 - 0.4737, or 0.5263.

If the ball lands on red, the player wins $3, and if it lands on black or green, the player loses $3.

The expected value (EV) f betting $3 on red is:

EV = (probability of winning * amount won) + (probability of losing * amount lost)

EV = (0.4737 * $3) + (0.5263 * -$3)

EV = $1.42 - $1.58

EV = -$0.16

The standard deviation (SD) of betting $3 on red is:

SD = √[(probability of winning * (amount won - EV)²) + (probability of losing * (amount lost - EV)²)]

SD = √[(0.4737 * ($3 - (-$0.16))²) + (0.5263 * (-$3 - (-$0.16))²]

SD = √[(0.4737 * $9.98) + (0.5263 * $8.06)]

the probability of transitioning from state 1 to state 2 after the first transition is:

P(X(t) enters state 2 after the first transition | X(0) = 1) = 1 / 3

To write the system of ordinary differential equations (ODEs) for the transition probabilities Pᵢⱼ(t) of the given continuous-time Markov chain, we need to consider the rate at which the system transitions between different states.

Let Pᵢⱼ(t) represent the probability that the Markov chain is in state j at time t, given that it started in state i at time 0.

The ODEs for the transition probabilities can be written as follows:

dP₁₂(t)/dt = q₁₂ * P₁(t) - q₂₁ * P₂(t)

dP₁₃(t)/dt = q₁₃ * P₁(t) - q₃₁ * P₃(t)

dP₂₁(t)/dt = q₂₁ * P₂(t) - q₁₂ * P₁(t)

dP₂₃(t)/dt = q₂₃ * P₂(t) - q₃₂ * P₃(t)

dP₃₁(t)/dt = q₃₁ * P₃(t) - q₁₃ * P₁(t)

dP₃₂(t)/dt = q₃₂ * P₃(t) - q₂₃ * P₂(t)

where P₁(t), P₂(t), and P₃(t) represent the probabilities of being in states 1, 2, and 3 at time t, respectively.

Now, let's consider the second part of the question: Suppose that the initial state is 1. We want to find the probability that after the first transition, the process X(t) enters state 2.

To calculate this probability, we need to find the transition rate from state 1 to state 2 (q₁₂) and normalize it by the total rate of leaving state 1.

The total rate of leaving state 1 can be calculated as the sum of the rates to transition from state 1 to other states:

total_rate = q₁₂ + q₁₃

Therefore, the probability of transitioning from state 1 to state 2 after the first transition can be calculated as:

P(X(t) enters state 2 after the first transition | X(0) = 1) = q₁₂ / total_rate

In this case, the transition rate q₁₂ is 1, and the total rate q₁₂ + q₁₃ is 1 + 2 = 3.

Therefore, the probability of transitioning from state 1 to state 2 after the first transition is:

P(X(t) enters state 2 after the first transition | X(0) = 1) = 1 / 3

Explanation:

At the top of the proof, your teacher states "Given" followed by the relevant useful info. We simply repeat that info word for word as statement 1. This is how all proofs start out. We start with what we're given and try to build toward what we want to prove.

So this is why reason 1 is "given". Reason 2 is "given" also. When your teacher gives multiple statements like this, it's handy to break them up into the smallest pieces possible.

--------------------

For reason 3, we use the SAS Similarity rule here because we have congruent angles LPN and LNM (both 90 degrees each) and the sides are proportional due to the statement \(\frac{PN}{NM} = \frac{LP}{LN}\)

Notice how statement 3 builds entirely off from what statements 1 and 2 set up.
