replacing the first one. Find the probability of picking 1 almond cookie followed by another almond cookie. Show ALL your work AND write your answer as a fraction, decimal, and percent
Answers
Answer:
For Part A:
The total of 1+4+3 marbles is 8 marbles
P( blue ) = blue /total = 4/8 = 1/2
He replaces it, so there are still 8 marbles in the bag
P(blue 2nd draw) = blue /total = 4/8 = 1/2
P(blue,replace, blue) = 1/2*1/2 = 1/4
For Part B:
1 choc chip, 3 almond, 2 butter. 6 total cookies.
probability of picking 1 almond on first pick : 3/6 which is 1/2
without replacement
probability of drawing another almond : 2/5
Probability of drawing 1 almond followed by another (without replacement ) is:
3/6 * 2/5 = 6/30 = 1/5
Step-by-step explanation:
jane is eight years older than amy. if amy is now twice as old as jane was at one-third jane's current age, how old is jane now?
Answers
Currently Jane is 24 years old. Let's start by using variables to represent the ages of Jane and Amy. Let j be Jane's current age and a be Amy's current age.
From the first sentence of the problem, we know that j = a + 8. Now, let's focus on the second sentence of the problem. It says that Amy is now twice as old as Jane was at one-third Jane's current age.
Let's break down this sentence into smaller pieces. "Jane was at one-third Jane's current age" means that Jane's age at that time was j/3. "Amy is now twice as old as Jane was at one-third Jane's current age" means that:
a = 2(j/3)
3/2 × a = j
Now we have two equations that relate the ages of Jane and Amy:
j = a + 8
3/2 × a = j
We can substitute the first equation into the second equation to get an equation that only has one variable:
1/2 × a = 8
a = 16
So Amy = 16 years old. We can use the first equation to find Jane's age:
j = a + 8
j = 16 + 8
j = 24
Currently Jane is 24 years old.

Answers
A. The solution to the equation 5 + x - 12 = 2x - 7 is 0.
B. The values of x = -0.5, 0, and 1 have been you used to prove the solution.
How to solve the given equation?Based on the information provided above, we can logically deduce the following equation;
5 + x - 12 = 2x - 7
By rearranging and collecting like terms, we have the following:
2x - x = 5 - 12 + 7
x = 0
Part B.
When x = -0.5, we would substitute -0.5 into the equation as follows;
5 + x - 12 = 2x - 7
5 + (-0.5) - 12 = 2(-0.5) - 7
5 - 0.5 - 12 = -1 - 7
-8.5 ≠ 8
When x = 0, we would substitute 0 into the equation as follows;
5 + x - 12 = 2x - 7
5 + (0) - 12 = 2(0) - 7
5 - 0 - 12 = 0 - 7
-7 = -7
When x = 1, we would substitute 1 into the equation as follows;
5 + x - 12 = 2x - 7
5 + (1) - 12 = 2(1) - 7
5 - 1 - 12 = 1 - 7
-8 ≠ -6

The parent function f(x)=x^2 is translated 2 units left and 3 units up. Write the quadratic function in vertex form.
Answers
The quadratic function in vertex form is formed as: f(x)=a(x + 2)² + 2.
Explain the vertex form of quadratic function?In the linear model, k defines the vertex of the parabola, just as adding or subtracting b would decide where the line crosses.f(x)=a(x - h)² + k
K functions like b with in slope-intercept formula, just like a linear function would.For the stated question-
Whether you're going to increase by 2, you must also add 2.
The horizontal movement is determined by the h. It goes left or right depending on what you enter in h.
Finding the value that will cause the parenthesis to equal 0 when x equals -2 is necessary to make the necessary adjustments because shifting the vertex point to a left implies subtraction and negatives
x - h = 0
-2 - h = 0
-h = 2
h = -2
As a result, the function appears as follows:
f(x)=a(x - (-2))² + 2
A negative is subtracted to eliminate the signs and create a positive:
f(x)=a(x + 2)² + 2
Thus, the quadratic function in vertex form is formed as: f(x)=a(x + 2)² + 2.

Using the simulation to represent the vector, the car's speed in the north direction is approximately 9.225 miles/hour.
Using the simulation, the car's speed in the east direction is approximately 17.126 miles/hour.
To calculate the components without using the simulation, we can use trigonometry. The compass reading of 36.9% north of east can be converted to an angle. The angle between the vector and the east direction is given by:
Angle = arctan(North component / East component)
Using this angle, we can determine the components of the vector. The north component is given by:
North component = (Speed) * cos(Angle)
The east component is given by:
East component = (Speed) * sin(Angle)
By substituting the values of the speed and angle, we can calculate the north and east components of the vector.
If you drove 10 miles east and then 8 miles south, and your friend drove 8 miles west and then 8 miles north, you would have formed a right triangle with sides of length 10 miles and 8 miles. The distance the homing pigeon would have to fly to get back to the dealership can be calculated using the Pythagorean theorem:
Distance = \(\sqrt((10 miles)^2 + (8 miles)^2)\)

Identify and explain the processes that are used to show that a function is either a state or path function. Provide an example of each case - state or path - for each process you identify.
Answers
The processes used to determine if a function is a state or path function include integration/differentiation and examining the differential form of the function. Integrating a function with respect to a variable yields a state function, while differentiating a function with respect to a variable yields a path function.
If the differential form of a function involves only state variables, it is a state function. If it involves both state and path variables, it is a path function.
To determine whether a function is a state or path function, we can examine the properties of the function and the variables involved. A state function depends only on the current state of the system and is independent of the path taken to reach that state. In contrast, a path function depends on the path taken to reach a particular state.
One common process used to determine the nature of a function is integration or differentiation. Integrating a function with respect to a variable yields a state function, whereas differentiating a function with respect to a variable yields a path function. For example, integrating the pressure (P) with respect to volume (V) yields a state function called the internal energy (U). On the other hand, differentiating the work (W) with respect to volume (V) yields a path function known as pressure (P).
Another process used is the examination of the differential form of the function. If the differential form of a function involves only state variables, then the function is a state function. For instance, the differential form of the enthalpy (H) involves only state variables (dH = dU + PdV), making it a state function. However, if the differential form involves both state and path variables, the function is a path function. An example is the differential form of heat (Q), which involves both state and path variables (dQ = dU + PdV), indicating that it is a path function.

Answers
Plan B is expected to be worth the most in 100 years due to its exponential growth nature.
Based on the given information, Plan B will be worth the most in 100 years. This is because Plan B grows according to an exponential function, while Plan A grows according to a linear function.
Exponential growth means that the value of an investment increases at an increasing rate over time. In the context of a long-term investment like the one mentioned, exponential growth can lead to significant gains over time.
On the other hand, linear growth implies a constant rate of increase. While Plan A may still yield positive returns, it is likely to be outperformed by the exponential growth of Plan B over a 100-year period.
Therefore, Plan B is expected to be worth the most in 100 years due to its exponential growth nature.

Answers
Answers:
m = 3/4b = -3/4Note: 3/4 = 0.75
====================================================
Explanation:
The first thing we need to do is solve that given equation for y
4x+3y = 3
3y = 3-4x
3y = -4x+3
y = (-4x+3)/3
y = (-4x)/3 + 3/3
y = (-4/3)x + 1
This last equation is in slope intercept form, y = mx+b, where,
m = -4/3 = slopeb = 1 = y interceptThese m and b values are not the final answer unfortunately, as we have yet to determine anything about the perpendicular line. However, it helps us build toward the answer.
We'll focus on the slope.
Apply the negative reciprocal to -4/3 to get 3/4. We flip the fraction and the sign from negative to positive.
This means the perpendicular slope is 3/4 and this value goes in the first box.
-----------------------------
From here, we'll use the fact that the perpendicular line goes through the point (x,y) = (5,3)
i.e. we have x = 5 and y = 3 pair up together.
Use that perpendicular slope we found earlier to say,
y = mx+b
3 = (3/4)*5 + b
3 = 15/4 + b
3 - 15/4 = b
12/4 - 15/4 = b
(12-15)/4 = b
-3/4 = b
b = -3/4 is the y intercept of the perpendicular line
Answer:

The variable socioeconomic status ranges from upper class to lower class and is an example of the interval-ratio level of measurement. (option c)
Ordinal level of measurement is used to categorize variables that can be ranked in a specific order but do not have a uniform difference between them. For instance, a student's class rank can be categorized as first, second, or third. However, there is no uniform difference between the ranks.
Ratio level of measurement is used to categorize variables that have a meaningful zero point. For instance, height, weight, and age have a meaningful zero point.
However, in reality, it is difficult to find a person with zero income or zero education. Therefore, socioeconomic status can be considered an example of interval-ratio level of measurement but not an example of ratio level of measurement.

Taylor started with $8 and added $10 every week. give equation
Answers
To find the equation for Taylor's situation, we can start by defining some variables. Let's let "w" represent the number of weeks that have passed since Taylor started.
We can also let "a" represent Taylor's starting amount of money, which is $8. Now, we know that Taylor adds $10 every week. So after one week, Taylor will have a total of $18 ($8 + $10). After two weeks, Taylor will have a total of $28 ($8 + $10 + $10). And so on. We can see that Taylor's total amount of money after "w" weeks can be represented by the equation: Total amount = a + 10w. Plugging in the values we defined earlier, we get: Total amount = 8 + 10w
This is the equation for Taylor's situation.
It tells us that the total amount of money Taylor has after "w" weeks is equal to $8 plus $10 times the number of weeks that have passed. It's worth noting that we could also write this equation in slope-intercept form as: y = 10x + 8. Where "y" represents the total amount of money Taylor has and "x" represents the number of weeks that have passed. This equation shows us that the slope of the line (which represents how much Taylor's total amount of money increases each week) is 10, and the y-intercept (which represents Taylor's starting amount of money) is 8.
