Suppose you are doing a 5000 piece puzzle. you have already placed 175 pieces. every minute you place 10 more pieces. after 50 minutes, how many pieces will you have placed

Answer:

8x² + 8

Step-by-step explanation:

Given

(x² + 3)² - (x² - 1)² ← expand factors using FOIL

= \(x^{4}\) + 6x² + 9 - (\(x^{4}\) - 2x² + 1) ← distribute by - 1

= \(x^{4}\) + 6x² + 9 - \(x^{4}\) + 2x² - 1 ← collect like terms

= 8x² + 8

Answer step-by-step explanation:

solution set is { 3,4 }

4/15

3.65

n=9

5x + 4 < 29

5x < 29 - 4

5x < 25

x < 25/5

x < 5

solution set is { 3,4 }

Simple math

1. 3.42 + 5.76 = 9.18

2. 12.83 - 9.18 = 3.65

3.65 would be the cost of the notebook Jen bought

Given that Bobbi, Kate, and Rebecca earned a combined 12 points during their team's game.

If n is the unknown point made by Rebecca then we get

total = 12

Bobbi earned = 6 points

Kate earned = 3 points

Total = 6+3+n =12

So answer is

6+3+n=12

n=9

I guess that this would work for these Part A.....let x be the amount he earned on Sunday.....so

Amount earned on Saturday + amount earned Sunday =

11 + x =

Represents the total amount he earned

Part B

Let N be the number of dogs that Kyle walked

Then, Larry walked 2N + 4 dogs

Anything given that is not a definite number and has phrases like "does not know", "is looking for" will most likely indicate that it is the variable. We can represent the no. of desserts with the variable x like most equations do.

An expression representing how many strawberries will be needed in x desserts: 4x The variable "x" represents the number of desserts Heather will make.

In part B, we are given the ounces of strawberries Heather will be using. With the expression above, we can make an equation out of it. 4x = 24 With "x" of desserts, Heather is making, all we have to do is solve for the value of "x" to find the no. of desserts she will make with 24 ounces of strawberries. Divide both sides by 4. x = 6 She can make 6 desserts with 24 ounces of strawberries.

In each of these phrases, there is a correlation between two variables, but there is no clear evidence that one variable causes the other.

Correlation without causation occurs when two variables appear to be related, but there is no evidence to suggest that one variable causes the other. In other words, the correlation may be due to other factors that influence both variables, rather than one causing the other. Here are some phrases that imply correlation without causation:

Ice cream sales and murder rates both increase in the summer.

Children who read more books tend to have higher test scores.

People who exercise regularly tend to have lower rates of heart disease.

Higher levels of education are associated with higher salaries.

People who own larger houses tend to have higher levels of debt.

Students who use more highlighters tend to get higher grades.

People who wear glasses tend to be smarter.

Countries with higher levels of chocolate consumption tend to have more Nobel laureates.

People who watch more TV tend to have higher rates of obesity.

In each of these phrases, there is a correlation between two variables, but there is no clear evidence that one variable causes the other. For example, the fact that ice cream sales and murder rates increase in the summer may be due to the fact that more people are out and about in the warm weather, rather than one causing the other.

It is important to remember that correlation does not always imply causation, and that other factors may be at play when two variables appear to be related. Therefore, it is essential to carefully examine the evidence and consider alternative explanations before drawing conclusions about cause and effect.

The function that represents the given equation is:

f(x) = 3x + 8

The equation is -12x + 4y = 32. To solve for y as a function of x, we need to isolate y on one side of the equation.

Adding 12x to both sides, we get 4y = 12x + 32.

To solve for y, we divide both sides of the equation by 4. This gives us y = 3x + 8.

Hence, the function that expresses y as a function of x is:

f(x) = 3x + 8.

Using this function, we can determine the value of y corresponding to any given x value. For example, if we substitute x = 5 into the function, we have f(5) = 3(5) + 8 = 15 + 8 = 23. Therefore, when x is 5, y is 23 according to the function f(x) = 3x + 8.

In summary, the function f(x) = 3x + 8 represents the relationship between x and y in the given equation, allowing us to calculate the corresponding y value for any given x value.

Therefore, the function that represents the given equation is:

f(x) = 3x + 8

The equation of the line that passes through point (8,-5) and perpendicular to y = x - 2 is y = -x + 3.

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Given that:

y = x - 2

To the equation of the line that passes through the point (8,-5) and is perpendicular to the line.

First, determine the slope of the initial line using the slope intercept-form. y = mx + b

y = x - 2

Slope m = 1

For the equation of line perpendicular to the initial line, its slope must be a negative reciprocal of the initial slope.

Hence, slope of the perpendicular line is;

Slope m = -1/1

Slope m = -1

Next, find the equation of the perpendicular line, by using the point slope formula.

y - y₁ = m( x - x₁ )

Plug in the slope m ( -1 ) and point (8,-5).

y - (-5) = -1( x - 8 )

y + 5 = -x + 8

y = -x + 8 - 5

y = -x + 3

Therefore, the equation of the line is y = -x + 3.

Answer:

Step-by-step explanation:

a) If the student misses his alarm, the probability that he is not late to school is 0.25.

b) The probability that the student is late to school is 0.65.

c) One day, the student shows up to school on time. The probability that he missed his alarm is 0.59.

For A,

Let A be the event that the student wakes up on time, and B be the event that the student is late to school. We want to find P(B).

By definition,

P(B) = 1 - P(A)

where A is the event that the student misses his alarm.

Therefore,

P(B) = 1 - P(A)

= 1  -0.75

We are given that P(A') = 0.75, so

P(B) =0.25

For B,

To calculate the probability that the student is late to school, we will use the following formula:

P(X = x) = n!/(x!(n-x)!) * p^x * (1-p)^(n-x)

where:

P(X = x) is the probability that the student is late to school

n is the number of trials

x is the number of events

p is the probability of an event occurring

For this problem, we will let n = 1 and x = 1.

Now that we have our formula, we can plug in our values to solve for P(X = x).

P(X = x) = 1!/(1!(1-1)!) * 0.65^1 * (1-0.65)^(1-1)

P(X = x) = 0.65

We can interpret this answer as follows: there is a 0.65 probability that the student is late to school.

For C,

We first need to find the probability that the student did not miss his alarm, which is 1 - 0.59 = 0.41. We then need to find the probability that the student showed up to school on time given that he did not miss his alarm, which is 1 - 0.41 = 0.59.

Mass = 32.16 grams [32.2 grams for 3 sig figs)

Step-by-step explanation:

Density = Mass/Volume

Density = 2.4g/cm^3

Volume = 13.4cm^3

---

2.4g/cm^3 = Mass/13.4cm^3

Mass = (2.4g/cm^3)*(13.4cm^3)

Mass = 32.16 grams [32.2 grams for 3 sig figs)

The mass of the glass-bottle is 32.16 grams.

Space occupied by an object in three-dimensional space is called as volume of an object. In simple words, space is taken by object.

Given:

The density of glass in a bottle is 2.4 grams per cubic centimeters.

The volume of glass used to make the bottle is 13.4 grams per cubic centimeters.

Density = Mass/Volume

Density = 2.4 grams per cubic centimeters.

Volume = 13.4 cubic centimeters.

Substituting all the values,

2.4 = Mass / 13.4

Mass = 13.4 x 2.4

Mass = 32.16

Therefore, mass = 322.16 grams.

The amount of total cost at q* is 1.

To determine the production level that minimizes total cost, we need to find the value of q (production level) at which the derivative of the total cost function TC(q) is equal to zero. Let's begin by finding the derivative of TC(q):

TC(q) = 10 - 6q + q^2

To find the minimum point, we differentiate TC(q) with respect to q:

d(TC(q))/dq = -6 + 2q

Setting the derivative equal to zero and solving for q:

-6 + 2q = 0

2q = 6

q = 3

So the production level q* that minimizes the total cost is 3.

To find the amount of total cost at q*, we substitute q = 3 into the total cost function TC(q):

TC(q*) = 10 - 6(3) + (3)^2

TC(q*) = 10 - 18 + 9

TC(q*) = 1

Therefore, the amount of total cost at q* is 1.

The given unity feedback system is the type-1 system, which can be observed from the given open-loop transfer function G(s).

Steady state error is the difference between the input and the output as time approaches infinity. It is also the difference between the desired value and the actual output at steady-state.

The steady-state error is calculated using the error coefficient, which depends on the type of the system.Find the steady-state error if the input is 80u(t):The transfer function of the given system can be written as follows;G(s) = 80(8²)/(s+4)(8+6)(8+17)The type of the given system is the type-1 system.

174 of the 300 students in school chose pizza or hamburgers as their favorite meal.

We know that from the definition of Probability that,

Probability of an Event = (The favorable number of incidents under that Event)/(Total number of incident)

Here given that the total number of classmates in first = 50

Number of students whose favorite meal is pizza = 12

Number of students whose favorite meal is hamburgers = 17

So the probability of a student has pizza or hamburger as his favorite meal is = (12 + 17)/50 = 29/50

So for 300 such students, the number of students choose pizza or hamburger as their favorite meal is = 300*(29/50) = 6*29 = 174.

The police should be concerned with only one crime scene, which is the location of the abduction.

The police should be immediately concerned with one crime scene, which is the location where the 12 year old girl was abducted from. A crime scene is a location where a crime has occurred or was suspected of having occurred. Investigators and law enforcement officials will gather and analyze physical evidence found at the scene of a crime to help determine what occurred, who was involved, and whether or not a crime has been committed. In this case, the location where the 12 year old girl was abducted from is the crime scene.

The police have done the investigation and identified the van used in the abduction, which was registered to Roger P. Anderson of 1594 Maple Drive. However, the location of the registered owner of the van is not considered a crime scene until evidence that links them to the crime scene is found.

The probability that the student is a junior is 0.5.

The probability that the selected student takes calculus is given by:

P(C) = probability that the selected student takes calculus= probability of seniors taking calculus + probability of juniors taking calculus= 0.4 x 1/2 + 0.2 x 1/2= 0.2

Now,Let's find the probability that a calculus student selected is a junior.i.e., we need to find P(J|C).We know that,

P(J|C) = probability that the selected student is a junior given that the student takes calculus= P(C|J) × P(J) / P(C)
