oint-slope form of the line that passes through the point (7, −4) and has a slope of m=−6.
Answer: \(y-(-4) = -6(x-7)\) (or \(y+4 = -6(x-7)\))
Step-by-step explanation:
Point-slope form is \(y-y_{1} = m(x-x_{1})\). Y and X are the current X and Y values. M is the slope. X\(_{1}\) and Y\(_{1}\) are the X and Y values of points along the line.
So to convert your point and slope into point-slope form, you have to plug in your values. First of all, replace the M, which is the slope, with your value of m: -6.
At this point, the equation is \(y-y_{1} = -6(x-x_{1})\).
Now you plug in the X and Y values of points along the line. Replace X\(_{1}\) with 7, because that's the X value of the ordered pair you were given. Then, replace Y\(_{1}\) with the Y value of your ordered pair, which is -4.
Now, the equation is \(y-(-4) = -6(x-7)\).
(Lastly, on the left side of the equation, you're subtracting a negative number, which is the same of adding a positive number. You can change that part to \(y + 4\) instead. However this answer might not be the answer your teacher/course wants, because it's not TOTALLY in point-slope form.)
Hopefully this helps! Best of luck!

Suppose a person offers to play a game with you. In this game, when you draw a card from a standard 52-card deck, if the card is a face card you win $2, and if the card is anything else you lose $1. If you agree to play the game, what is your expected gain or loss (in dollars) per game
The expected loss per game is approximately -$0.31.
The terms we need to consider in this problem are: standard 52-card deck, face cards, and expected gain or loss.
To find the expected gain or loss per game, follow these steps:
1. Determine the probability of drawing a face card.
There are 12 face cards (Kings, Queens, and Jacks) in a standard 52-card deck. So the probability of drawing a face card is \(\frac{12}{52}\), which simplifies to \(\frac{3}{13}\).
2. Determine the probability of drawing a non-face card.
There are 40 non-face cards in the deck (52 cards - 12 face cards). So the probability of drawing a non-face card is \(\frac{40}{52}\), which simplifies to \(\frac{10}{13}\).
3. Calculate the expected gain or loss per game.
Expected gain or loss = (Probability of drawing a face card x gain from drawing a face card) + (Probability of drawing a non-face card x loss from drawing a non-face card)
4. Simplify the equation.
Expected gain or loss = \((\frac{3}{13} (2)) + (\frac{10}{13} (-1))\)
Expected gain or loss = \(\frac{-4}{13}\)
Your expected loss per game is approximately -$0.31 (rounded to two decimal places).

Two cyclists start at the same time from opposite ends of a course that is 45 miles long. One cyclist is riding at 14 mph and the second cyclist is riding at 16 mph. How long after they begin will they meet
If the distance is 45 miles and speed of both cyclist is 14 and 16 miles per hour then they will take time of 1.5 hour to meet.
Given First cyclist is riding at 14 miles per hour and second at 16 miles per hour. The distance is 45 miles.
We know that speed is the distance covered by an object in a particular period of time.
Speed=distance/time.
It is expressed as kilometers per hour or miles per hour, etc.
If both riders are riding towards each other then the speed will be 16+14 =30 miles per hour.
Distance=45 miles.
Time =distance/speed

AC (b)
Solution:
Apply the Law of Sines
\( \frac{b}{sin(B)} = \frac{c}{sin(C)} \)
Plug in the values
\( \frac{b}{sin(132)} = \frac{6}{sin(23)} \)

Simplify 2h+3h^2−4g^4+5f^2+11g^4−4h+f^2
Answer:3h^2 + 7g^4 + 5f^2 - 4h - 4g^4
Step-by-step explanation:To simplify the expression 2h+3h^2−4g^4+5f^2+11g^4−4h+f^2, we can follow these steps:
Group together like terms:
2h + (-4h) = -2h
3h^2 + f^2 = 3h^2 + f^2
-4g^4 + 11g^4 = 7g^4
This gives us the expression: -2h + 3h^2 + 5f^2 + 7g^4
Combine the constants:
3h^2 + 5f^2 + 7g^4 = 3h^2 + f^2 + 7g^4
Combine the like terms:
-2h + 3h^2 + f^2 + 7g^4 = 3h^2 + f^2 + 7g^4 - 2h
So, the simplified expression is: 3h^2 + 7g^4 + 5f^2 - 4h
After simplifying, the expression we'll get, 2h+3h^2+7g^4+6f^2-4h.
To simplify these algebraic expressions, we need to group the like terms. Like terms can be defined as terms that contain the same variables raised to the same power. Only the numerical coefficients are different.
After grouping like terms, perform the required operations. Here we have two operations i.e addition and subtraction. So group the like terms which need to add and those which need to subtract.
For example, Here -4g^4+11g^4 are like terms and 5f^2+f^2 are like terms. So we'll subtract 4 from 11, we'll get 7 and the variable will remain the same that is g^4. Similarly, we'll add 5 and 1, we'll get 6 and the variable will remain the same that is f^2.
Other terms will remain as it is.
2h+3h^2+(-4g^4+11g^4)+(5f^2+f^2)-4h
2h+3h^2+7g^4+6f^2-4h
Therefore the answer is, 2h+3h^2+7g^4+6f^2-4h

It is useful to compare a logistic regression model against some kind of baseline state. Which of the following is the baseline state that is usually used in logistic regression? a. Predicts a categorical outcome variable. b. Does not have b weights c. Is not open to sources of bias. d. Log-transforms the predictor variables
In logistic regression, it is important to compare the performance of the model against some kind of baseline state to evaluate its effectiveness.
The baseline state that is commonly used in logistic regression is the model that does not have any b weights. This is because the b weights in logistic regression represent the strength of association between the predictor variables and the outcome variable. If a logistic regression model with b weights performs better than the baseline model without b weights, it indicates that the predictor variables are significant in predicting the outcome variable. Additionally, the baseline model is not open to sources of bias, and it does not predict the categorical outcome variable. Therefore, it is important to use the baseline model to determine the usefulness and predictive power of the logistic regression model. Log-transforming the predictor variables is not the baseline state in logistic regression.

The volume of a sphere is (500π)/3 cubic inches. What is the circumference of the great circle of the sphere? (Use 3.14 for pi. Round the answer to the nearest tenth, if necessary. Recall that the formula for the volume for a sphere is v=4/3πr^3 and the formula for the circumference of the great circle is c=πd.)
The circumference of the great circle of the sphere is approximately 31.4 inches.
To find the circumference of the great circle of the sphere with a volume of (500π)/3 cubic inches, we will first find the radius (r) using the volume formula, and then use the circumference formula.
Step 1: Use the volume formula to find the radius.
The volume formula for a sphere is V = (4/3)π\(r^3\). We are given the volume as (500π)/3, so we can set up the equation:
(500π)/3 = (4/3)π\(r^3\)
Step 2: Solve for r.
To solve for r, we can first divide both sides by (4/3)π:
[(500π)/3] / [(4/3)π] = \(r^3\)
Cancelling the π and the 3 from both sides, we get:
500 / 4 = \(r^3\)
125 = \(r^3\)
Now, take the cube root of both sides:
r = 5
Step 3: Use the circumference formula to find the circumference of the great circle.
The circumference formula for a circle is C = πd, and since the diameter (d) is twice the radius, we have:
C = π(2r) = π(2 × 5) = 10π
Step 4: Calculate the circumference using 3.14 for π and round to the nearest tenth.
C = 10 × 3.14 ≈ 31.4
