Yes, that is correct. A well-formed formula is a specific arrangement of symbols that results in a grammatically correct and meaningful expression.

In other words, the arrangement of symbols in a formula must follow the rules of grammar and syntax in order to convey a coherent message or statement. Without proper arrangement and adherence to grammatical rules, the resulting expression may be nonsensical or ambiguous.
A well-formed formula (WFF) is an arrangement of symbols in which the resulting expressions are grammatically correct and meaningful. This means that the symbols follow a specific set of rules and structure, ensuring that the expressions make logical sense and can be properly interpreted or analyzed.

(a) The expression for the width of the rectangle is 7x + 1.

(b) The expression for the perimeter of the rectangle is 14x + 14.

(c) when x = 1/2, the perimeter of the rectangle is 21 in

The area of a rectangle is given by the formula:

A = L × W

where L and W are the length and width of the rectangle respectively

(a) Since A = 42x + 6 sq inches and L = 6 in. We have:

42x + 6 = 6 × W

42x + 6 = 6W

6W = 42x + 6    (divide through by 6)

W = 7x + 1 in

Thus, the expression for the width of the rectangle is 7x + 1

(b) The expression for the perimeter of the rectangle

The perimeter of a rectangle is given by the formula:

P = 2(L + W)

P = 2(6 + 7x + 1)

P = 2(7 + 7x)

P = 14x + 14 in

(c) when x = 1/2

P =  14x + 14

P = 14×(1/2) + 14

P = 7 + 14

P = 21 in

Multiply number of packs bought by the price per pack:

6 x $1.75 = $10.50

Answer: $10.50

The price at which the total quantity supplied is 250 is $11.58.

In order to find the price at which the total quantity supplied is 250, we need to equate the total quantity supplied by both producers (Supply 1 and Supply 2) and solve for the price.

Supply 1: P = 6 + 0.7Q

Supply 2: P = 16 + 0.6Q

To find the equilibrium price, we set the total quantity supplied equal to 250:

0.7Q + 0.6Q = 250

1.3Q = 250

Q = 250 / 1.3 ≈ 192.31

Now that we have the quantity, we can substitute it back into either supply function to find the price. Let's use Supply 1:

P = 6 + 0.7Q

P = 6 + 0.7 * 192.31

P ≈ 6 + 134.62

P ≈ 140.62

Therefore, the price at which the total quantity supplied is 250 is approximately $11.58.

Answer:

57.6

Step-by-step explanation:

48% is the same as 0.48

so 120 * 0.48 = 57.6

Step-by-step explanation:

The following are quadratic equations:

x² + 3x - 5 = 0,

x² - x = 3x + 7,

7x² + 14x = 0.

Answer:   y = (1/2)x-2

This is the same as y = 0.5x-2

Slope = 1/2 = 0.5

Y intercept = -2

========================================================

Work Shown:

Compare the equation to y = mx+b to find that m = -2 is the slope.

Think of -2 as -2/1. Flip the fraction to get -1/2. Then flip to positive getting 1/2.

The original slope is -2. The perpendicular slope is 1/2 = 0.5

We'll use this perpendicular slope alone with (x,y) = (-4,-4) to get the following for b

y = mx+b

-4 = 0.5*(-4) + b ... plug in the m,x, and y values mentioned above

-4 = -2 + b

-4+2 = b ... adding 2 to both sides

-2 = b

b = -2

Since m = 0.5 and b = -2, we go from y = mx+b to y = 0.5x-2

This is the same as y = (1/2)x-2 since 1/2 = 0.5

If the original quantity is 8 and the new quantity is 2, then the correct answer is 75%.

For this question we need to subtract and multiply the numbers. We know that 2 = 25% of 8 so:

\(\boxed{8-2=6}\\\boxed{6/2=3}\)

We are going to take that 25% and multiply it with 3 to get are final answer.

\(\boxed{25*3=75}\\\boxed{So,2=75}\)

Therefore, If the original quantity is 8 and the new quantity is 2, then the correct answer is 75%.

Answer:

B. Parallelogram

Step-by-step explanation:

1. It can't be a square since all 4 sides need to be equal. Squares have 4 equal angles (90 degrees angles)

2. A parallelogram is a four-sided figure with two pairs of parallel sides. This fits exactly with the image that is shown. But let's check the other answers first.

3. While rectangles also have 2 pairs of parallel sides, rectangles have 4 equal angles (90 degrees angles) just like squares do, it can't be a rectangle.

4. A rhombus has four equal sides, meaning this figure can't be a rohmbus.

5. It can't be a trapezoid since trapezoids only have one pair of parallel sides. This figure has 2 pairs of parallel sides.

6. Only B. Parallelogram could possibly be right. Therefore, the answer to this question is that  B. Parallelogram is the type of polygon that this figure is.

Logistic regression models the probability of a binary outcome, while CART models segment data into categories. For example, CART is preferable when data has complex interactions, as it can partition data into multiple categories.

Logistic regression and classification and regression trees (CART) are two different machine learning models used for binary classification problems. Logistic regression models the probability of one class or the other based on a linear combination of input variables. This makes it useful for predicting a binary outcome, such as whether a customer will purchase a product or not. On the other hand, CART is a decision tree model that divides data into categories. It uses a tree-like structure to split the data into segments based on the input features. This makes it useful for dealing with data with complex interactions, as it can partition data into multiple categories. For example, a CART model would be preferable to a logistic regression model if there are multiple underlying factors that affect the binary outcome. In this case, a CART model could more accurately identify the categories that are associated with a particular outcome. Overall, CART models are superior for dealing with data with complex interactions, whereas logistic regression is better for simpler data.

The required positive numbers are 14.43, 14.43.

According to the statement

we have given that The product of two positive numbers is 208 and the sum is a minimum.

And we have to find these numbers.

So, For this purpose,

Let two positive numbers xy = 208

According to question xy = 208

And then

y = 208/x

and

sum of two positive numbers z=x+y

s= x+ 208/x

then

differentiate with respect to x

ds /dx = d/ dx(x+ 208/x)  -(1)

ds /dx = 1 - 208/ x^2

here ds /dx = 0. so,

1 - 208/ x^2 = 0

x^2 - 208= 0

x = 14.43.

And

differentiate the equation (1) again

d^2s /dx^2 = 0 + 416/x^2)  

then

∴ at point x= 14.43,

d^2s /dx^2 = 416/208.22

d^2s /dx^2 = 1.99

which is greater than zero.

∴ value of s minimum at point x = 14.43

so, y = 208/x

y = 208 /14.43

y = 14.43.

So, The required positive numbers are 14.43, 14.43.

Answer:

2 4/5 = 14/5 Answer is A

Step-by-step explanation:

Let x= the average for all three classes combined. So x=85.25.

When you add two or more numbers and divide the result by the number of numbers you added together, you obtain an average.

The arithmetic mean is determined by adding a collection of numbers, dividing by their count, and obtaining the result.

average  =  total points / number of students

total points = average*number of students

Let the total number of students in  each class = a , b  and x

The total number of points the first class amassed  was   80a

The total number of points amassed by the second class was  85b

The total number of points amassed by the third class = 89c

For the first two classes we have

[ 80a + 85b ] / [ a + b] = 83

80a + 85b = 83a + 83b  

subtract  80a, 83b from both sides    

3a = 2b

a = 2/3b

For the second two classes we have

[ 85b + 89c ]  / [ b + c ]  =  87  

[  85b + 89c ]  = 87 [b + c]

85b + 89c = 87b + 87c      

subtract  85b, 87c from both sides

2c = 2b  

b  = c

For the three classes.....

Total points by all three classes /  number of class members  = the average for all three classes

[ 80a + 85b  + 89c ] /  [ a + b + c ]   =[sub for  a and c ]  

[80 (2/3)b  + 85b  + 89b]  /  [ (2/3)b  + b  + b ]  

b [ 80 (2/3)  + 85  + 89 ]  / [  b [( 2/3) + 1 + 1] ]       [cancel the b's ]

[ 80 (2/3) + 85 + 89]  [  8/3 ]

[ 160/3 + 85 + 89 ] /  [8/3] =

[ 160/3  + 255/3 + 267/3]  / [8/3]     multiply  top/bottom by 3

[160 + 255 + 267 ] / 8  =  

85.25  = average for all three classes
