Answer:
x=-6
Step-by-step explanation:
use distributive property on the () and times x and 1 by three
then you subtract 6 from both sides
then subtract three from both sides
then divide both sides by 3
your work would look like this:
3(x+1)+6=-9
3x+3+6=-9
3x+3=-15
3x=-18
x=-6
Hope this helps!
Answer:
X=6
Step-by-step explanation:
3(x+1)+6=−9
Step 1: Simplify both sides of the equation.
3(x+1)+69(3)(x)+(3)(1)+6=−9
(Distribute)
3x+3+6=−9(3x)+(3+6)=−9
(Combine Like Terms)
3x+9=−93x+9=−9
Step 2: Subtract 9 from both sides.
3x+9−9=−9−93x=−18
Step 3: Divide both sides by 3.

Fiona's fashion store is world renowned for its buttoned uniforms. A collection of 363636 shirts and 424242 jackets contains 842842842 buttons. A collection of 666 shirts and 777 jackets contains 137137137 buttons. Each shirt has the same number of buttons, and each jacket has the same number of buttons. How many buttons are there in a fiona's fashion shirt, and how many buttons are there in a jacket?.
The value of an integer or any letter associated with a variable is known as its coefficient. In the expression 2x + 3y, for instance, the variable x has a coefficient of 2 and the variable y has a coefficient of 3.
There are 842 buttons in 36 shirts and 42 jackets if the number of buttons in each is equal to x.
Additionally, the collection of six shirts and seven jackets has 137 buttons.
It can be expressed using the following equations:
36 x + 42 y = 842 ------(1);
6 x + 7 y = 137 ------(2);
6 x + 36 x + 42 y = 822 ------(3).
Although the constant term on one side of equation is different, the x and y coefficients are the same in both of these equations. This indicates that neither equation has a solution.

In a paint factory, an old conveyer line has filled 10 barrels of paint, and is filling more at a rate of 2 barrels per minute. A worker just switched on a newer line that can fill 3 barrels per minute. In a little while, the two lines will have filled an equal number of barrels. How many barrels will each line have filled?
Simplify and put into Slope-Intercept form
Answer:
see below
Step-by-step explanation:
First line:
y = mx+b where m is the slope and b is the y intercept
y = 2x + 10
Second line
y = mx+b
y = 3x+0 since there are no barrels filled on this line when they flip the switch
Setting the two equations equal
2x+10 = 3x
Subtract 2x from each side
2x+10-2x= 3x-2x
10 = x
Each line will have filled 10 barrels when they numbers are equal.

Dear Ms. Quadratic
I followed all of the directions given in your
brochure on how to order a parabola. I tried to
order a parabola that is passed through the points
(1,0) and (-6,0)
Answer:
We have the parabola as;
x^2 + 5x - 6
Step-by-step explanation:
Here, we want to get a parabola that passes through the points (1,0) and (-6,0)
The general form of a quadratic equation is;
y = ax^2 + bx + c
We have two x-intercepts at x = 1 and x = -6
A quadratic equation is expected to have two roots only and that means we have these two values as the roots
Hence, we have ;
(x-1) and (x + 6)
The parabola is thus;
(x-1)(x + 6)
= x(x + 6) -1(x + 6)
= x^2 + 6x - x -6
= x^2 + 5x - 6

a. An exponential growth rate equation to represent the cost C₁ of this home is \(C_1 = 250000e^{0.038t}\).
b. An exponential growth rate equation to represent the cost C₂ of this home is \(C_2 = 275000e^{0.022t}\).
c. The time in which each home would reach a price of $320,000 is 6.5 and 6.8 years respectively.
d. The price of the home in the first area is lower.
How to write an exponential growth rate equation for the cost?In Mathematics and Financial accounting, continuous compounding interest can be determined or calculated by using this mathematical equation (formula):
\(A(t) = P_{0}e^{rt}\)
Where:
A(t) represents the future value.P₀ represents the principal.r represents the growth rate.t represents the time measured in years.Part a.
Based on an exponential growth rate of 3.8% in the first area, the cost of this home in t years can be written as follows;
\(A(t) = P_{0}e^{rt}\\\\C_1 = 250000e^{0.038t}\)
Part b.
Based on an exponential growth rate of 2.2% in the second area, the cost of this home in t years can be written as follows;
\(A(t) = P_{0}e^{rt}\\\\C_1 = 275000e^{0.022t}\)
Part c.
At a price of $320,000 for the home, the number of years to reach this price is given by:
\(C_1 = 250000e^{0.038t}\\\\320000 = 250000e^{0.038t}\\\\1.28= e^{0.038t}\)
ln(1.28) = 0.038t
Time, t = 0.24686007793/0.038
Time, t = 6.49 ≈ 6.5 years.
\(C_2 = 275000e^{0.038t}\\\\320000 = 275000e^{0.022t}\\\\1.16= e^{0.022t}\)
ln(1.16) = 0.022t
Time, t = 0.14842000511/0.022
Time, t = 6.75 ≈ 6.8 years.
Part d.
The house with the lower price can be determined as follows;
\(C_1 = 250000e^{0.038 t}\\\\C_1 = 250000e^{0.038\times 3}\)
C₁ = 250,000 × 1.12075212488
C₁ = $280188.03122
\(C_2 = 275000e^{0.038t}\\\\C_2 = 275000e^{0.022 \times 3}\)
C₂ = $293762.347221.
In conclusion, the home in the first area is cheaper.

how to determine mean and standard deviation from a histogram in matlab
To determine the mean and standard deviation from a histogram in MATLAB, you can use hist" function then "the mean" function then std" function.
1. Use the "hist" function to create the histogram.
2. Use the "mean" function to calculate the mean of the data.
3. Use the "std" function to calculate the standard deviation of the data.
1. Use the "hist" function to create the histogram. For example, "hist(x)" will create a histogram of the data in the vector "x".
2. Use the "mean" function to calculate the mean of the data. For example, "mean(x)" will return the mean of the data in the vector "x".
3. Use the "std" function to calculate the standard deviation of the data. For example, "std(x)" will return the standard deviation of the data in the vector "x".
So, if you have a vector "x" containing the data you want to analyze, you can use the following code to determine the mean and standard deviation:
hist(x);
mean_x = mean(x);
std_x = std(x);
This will create a histogram of the data, and calculate the mean and standard deviation. You can then use these values to further analyze the data.

a company purchases shipments of machine components and uses this acceptance sampling plan: randomly select and test 25 components and accept the whole batch if there are fewer than 3 defectives. if a particular shipment of thousands of components actually has a 7% rate of defects, what is the probability that this whole shipment will be accepted?
If particular shipment of thousands of components actually has a 7% rate of defects, there is a 54.29% probability that this whole shipment will be accepted.
According to the company's acceptance sampling plan, 25 components are randomly chosen and tested from a shipment before the entire batch is accepted if there are no more than three defects. The probability of choosing a defective component from a sample of 25 is computed as follows, assuming that the shipment genuinely has a 7% defect rate:
P(defective) = 0.07
P(non-defective) = 0.93
Using the binomial distribution, we can calculate the probability of having 0, 1, or 2 defectives in a sample of 25:
P(X ≤ 2) = P(X=0) + P(X=1) + P(X=2)
= (0.93)²⁵ + 25(0.07)(0.93)²⁵ + (0.07)²(0.93)²³
= 0.5429
This means that there is a 54.29% chance of having 2 or fewer defectives in a sample of 25. Since the whole shipment will be accepted if there are fewer than 3 defectives in the sample, this is the probability that the whole shipment will be accepted. Therefore, there is a 54.29% chance that the company will accept the shipment based on their acceptance sampling plan.

a. 84 mph b. 92 mph c. 97 mph d. 81 mph
Thus, the answer is option (c) 97 mph.
An outlier is a value that lies significantly away from the rest of the values in the dataset. For a given dataset, we can determine outliers using z-scores.According to the problem statement, the mean speed of the fastballs thrown by major league baseball pitchers is 87 mph, and the standard deviation is 3 mph. To determine which speed is an outlier, we need to find its corresponding z-score.z = (x - μ) / σHere, x is the speed we want to test, μ is the mean speed, and σ is the standard deviation of speeds.Using the formula above, we can calculate the z-scores for each speed given in the options:a. z = (84 - 87) / 3 = -1b. z = (92 - 87) / 3 = 1.67c. z = (97 - 87) / 3 = 3.33d. z = (81 - 87) / 3 = -2Since a z-score of ±2 or higher is generally considered an outlier, the speeds of 97 mph and 81 mph are classified as outliers. Thus, the answer is option (c) 97 mph.

Suppose that 10 percent of the tubes produced by a machine are defective. If 6 tubes are inspected at random, determine the probability that: (a) Three tubes are defective; (b) At least four tubes are defective;
a) The probability that three tubes are defective is approximately 0.0146, or 1.46%.
b) The probability that at least four tubes are defective is 0.4686 or 46.86%.
To solve this problem, we can use the binomial probability formula:
P(X = k) = (n choose k) * p^k * (1-p)^(n-k)
where X is the number of defective tubes, n is the total number of tubes inspected, p is the probability that a tube is defective, and (n choose k) is the binomial coefficient, which represents the number of ways to choose k items out of n.
(a) To find the probability that three tubes are defective out of six, we can plug in n = 6, k = 3, and p = 0.1 into the formula:
P(X = 3) = (6 choose 3) * 0.1^3 * 0.9^3
= 20 * 0.001 * 0.729
= 0.01458
Therefore, the probability that three tubes are defective is approximately 0.0146, or 1.46%.
(b) To find the probability that at least four tubes are defective out of six, we can use the complementary probability:
P(X >= 4) = 1 - P(X < 4)
To find P(X < 4), we can add up the probabilities of having zero, one, two, or three defective tubes:
P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)
= (6 choose 0) * 0.1^0 * 0.9^6 + (6 choose 1) * 0.1^1 * 0.9^5 + (6 choose 2) * 0.1^2 * 0.9^4 + (6 choose 3) * 0.1^3 * 0.9^3
= 0.53144
Therefore, P(X >= 4) = 1 - 0.53144 = 0.46856, or approximately 46.86%.
So the probability that at least four tubes are defective is 0.4686 or 46.86%.

3. College logo T-Shirts priced at $15 sell at a rate of 25t-shirts per week, but when the bookstore marks them down to $10, it finds that it can sell 50 t-shirts per week. What is the price elasticity of demand for the logo Tshirts? Is it elastic, inelastic or unit elastic and WHY? Did the t-shirt make a good decision in lowering the price of t-shirts? WHY OR WHY NOT? Explain by calculating total revenue for each price at $15 and $10 and then use the price-total revenue test format to see if t-shirts are elastic, inelastic or unit elastic and WHY.
The price elasticity of demand (PED) for the logo T-shirts is 1.67, indicating that the demand for T-shirts is elastic. Lowering the price from $15 to $10 increased the total revenue, suggesting that the T-shirt made a good decision in lowering the price. This is because the price change led to a significant increase in quantity demanded and overall revenue.
To calculate the price elasticity of demand (PED), we can use the following formula:
PED = ((Q2 - Q1) / ((Q2 + Q1) / 2)) / ((P2 - P1) / ((P2 + P1) / 2))
Given that Q1 = 25, Q2 = 50, P1 = $15, and P2 = $10, we can substitute these values into the formula:
PED = ((50 - 25) / ((50 + 25) / 2)) / (($10 - $15) / (($10 + $15) / 2))
Simplifying this expression:
PED = (25 / 37.5) / (-5 / 12.5)
PED = (-2/3) * (-2.5) = 1.67
The price elasticity of demand (PED) for the logo T-shirts is 1.67.
Since PED is greater than 1, it indicates that the demand for T-shirts is elastic. This means that a decrease in price by 1% will result in a greater than 1% increase in quantity demanded. To determine if lowering the price was a good decision, we can analyze the effect on total revenue. The price-total revenue test states that:
If PED is elastic (greater than 1), a decrease in price will lead to an increase in total revenue.
If PED is inelastic (less than 1), a decrease in price will lead to a decrease in total revenue.
If PED is unit elastic (equal to 1), a change in price will have no effect on total revenue.
Let's calculate the total revenue at both prices:
Total Revenue at $15 = $15 * 25 = $375
Total Revenue at $10 = $10 * 50 = $500
Comparing the total revenue at each price, we can see that lowering the price from $15 to $10 increased the total revenue from $375 to $500. Therefore, the T-shirt made a good decision in lowering the price because it led to an increase in total revenue.
