A data set's mean (average) is calculated by adding all of the numbers in the set, then dividing by the total number of values in the set. When a data set is ranked from least to greatest, the median is the midpoint. The number that appears most frequently in a data set is called the mode.

MEAN =Sum of observations/Total number of observations.

MEDIAN= If n is odd, then the following formula is used: Value of (n+1/2th observation. If n is even, then the following formulae is used: {Value of (n/2) th observation + (n/2 +1)th observation/2}

MODE= Most number of times occurring value in the data

When  P(x) = [tex]x^3-3x^2+4x+32[/tex] is divided by x + 2 then the remainder is 4.

In the given question, when P(x) = [tex]x^3-3x^2+4x+32[/tex] is divided by x + 2 then we have to find the remainder.

The given equation is

P(x) = [tex]x^3-3x^2+4x+32[/tex]

We have to divide this equation by x+2.

To find the remainder we firstly equate x + 2 equal to zero to find the value of x.

x + 2 = 0

Subtract 2 on both side, we get

x = -2

Now we put x value in the given equation to find the remainder.

The equation

P(x) = [tex]x^3-3x^2+4x+32[/tex]

Put x = -2

P(x) = [tex](-2)^3-3(-2)^2+4(-2)+32[/tex]

Simplify

P(x) = -8 - 3×4 + (-8) + 32

P(x) = -8 - 12 - 8 + 32

P(x) = 4

Hence, when  P(x) = [tex]x^3-3x^2+4x+32[/tex] is divided by x + 2 then the remainder is 4.

The general form of a perfect square trinomial is (x + y)², where x and y are the roots of the trinomial. It can also be written as x² + 2xy + y² or x² + (2xy)x + y².

The general form of a perfect square trinomial is (x + y)^2, where x and y are the roots of the trinomial. To check if a trinomial is a perfect square, we can try to factor it into the square of a binomial. We can also complete the square method, which involves adding and subtracting the square of half of the x-coefficient of the linear term and then grouping the resulting terms.

It is important to note that for a trinomial to be a perfect square trinomial, the constant term must be a square of an integer and the linear term must be an even number.

The y-intercept of the line 4x + 2y ≥ 14 is y ≥ 7.

The y-intercept is the point where the graph intersects the y-axis. In other words, the y-intercept of a line is the value of y when x equals to zero.

In simpler term, the y-intercept of a function is the point(s) where the graph of the function crosses the y-axis.

Therefore, let's find the y-intercept of the inequality.

4x + 2y ≥ 14

let's substitute x as 0.

Therefore,

4x + 2y ≥ 14

4(0) + 2y ≥ 14

The percentages for this problem are given as follows:

The percentages are obtained applying proportions, as a percentage is the division of the number of desired outcomes by the number of total outcomes, and then multiplied by 100%.

651 adults were surveyed, of which 21 + 90 + 118 = 229 were affiliated with neither party, hence the percentage is of:

Step-by-step explanation:

negatives switch around the rules of positive so the one with the number tat is bigger when not negative is the lowest when negative

Co-prime numbers are those numbers that have only one common factor, namely 1.

Coprimes are pair of numbers that have no common factor other than 1. There should be at least two numbers to form a set of coprimes. Such numbers have only 1 as their highest common factor, for example (4 and 7), (5, 7, 9) are co-prime numbers. It should be noted that concurrent primes need not always be primes. If the only common factor of two numbers a and b is 1, then a and b are coprimes. In this case, (a, b) is considered a prime pair. Minor primes are also referred to as relatively primes. To determine whether any two numbers are co-prime, we first find their greatest common factor (GCF). If their GCF is 1, we can say they are co-prime. Consider the two numbers 5 and 9. The factors of 5 are 1 and 5. The factors of 9 are 1, 3, and 9. The factor that is common to both 5 and 9 is 1. The GCF of (5, 9) = 1. Thus, (5 , 9) is a co-prime pair.

The correct option is D.

Interest that compounded continuously to the principal amount. This interest rate provides exponential growth to a period of time.

Formula of continuous compound interest rate;

P(t) = P₀[tex]e^{rt}[/tex]

where P₀ is the principal amount, r is the interest rate and t is the time period.

A customer uses a store credit card to purchase a boat for $10,500.

The store credit card offers an annual interest rate, compounded continuously, of 18.99% with no payments due for the first two years.

That means,

P₀ = $10500, r = 18.99 and t = 2.

So,

P(t) = P₀[tex]e^{rt}[/tex]

Substituting the values,

P(t) = (10500)

P(t) = (10500)(1.46199)

P(t) = 15350.917

P(t) = $15350.92

It is the transformation of a value expressed in one unit of measurement into an equivalent value expressed in another unit of measurement of the same nature.

To solve this problem, we have to do the conversion of units with the given information:

Information about the problem:

By converting the unit from quart to ounce, we have:

1 quart * (32 ounce / 1 quart) = 32 ounce

Calculating the total of ingredients Jayden mixed we have:

Total ounces = Yogurt + peanut butter + honey

Total ounces = 32 ounces + 10 ounces + 6 ounces

Total ounces = 48 ounces

The slope intercept form of the following equation 6x - 2y = 18 is y = 3x - 9

We knwo that the slope intercept form of equation of line is y = mx + b, where m is the slope and b is the y-intercept.

Consider given equation,

6x - 2y = 18

6x - 2y - 6x = 18 - 6x          .......(Subtract 6x from each side)

- 2y = 18 - 6x

- 2y × (-1) = (18 - 6x) × (-1)       ......(Multiply each side by -1)

2y = -18 + 6x

2y/2 = (-18 + 6x)/2                   ..........(Divide each side by 2)

y = -18/2 + 6x/2

y = -9 + 3x

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle. The ratios of sides of a right-angled triangle with respect to any of its acute angles are known as the trigonometric ratios of that particular angle.

sin(tetha) = opp/hyp

cos ( tetha) = adj/hyp

tan ( tetha) = opp/ adj

In the triangle adj = 3b and hyp = 20

cos x = 3b/20

cos x = 3/5

therefore 3/5 = 3b/20

multiply both sides by 20

3/5×20 = 3b/20 × 20

3b = 12

To prove the congruence between two triangles there are several postulates, that can be applied depending on the congruent parts of the triangles.

The postulates are:

SAS (Side-Angle-Side): This postulate states that if two triangles have two corresponding sides congruent and one corresponding angle congruent, we can conclude that those triangles are completely congruent.

ASA (Angle-Side-Angle): This postulate states that if two triangles have two corresponding angles congruent and one corresponding side congruent, then those triangles are congruent.

SSS (Side-Side-Side): This postulate states that if two triangles have all three corresponding sides congruent, then triangles are congruent.

AAS (Angle-Angle-Side): If two pairs of corresponding angles are congruent and one pair of corresponding sides is congruent, then both triangle are congruent each other.

HL (Hypothenuse-Leg): this postulate is applied when we have right angles. It states that two right triangles are congruent if they have one pair of corresponding leg congruent, and the hypothenuses are also congruent. We could conclude that those right triangles are congruent.

From these postulate, we can demonstrate the congruence between two triangles. Then, from that congruence, we deduct the congruence between each corresponding parts of those triangles. For example, if we demonstrate the congruence by AAS, we deduct that the third angle is also congruent, and the other two sides are also congruent.

P = 2(L + W), where P is the perimeter, L is the length and W is the width of the rectangle. In simpler terms, it is the total distance around the rectangle.

The perimeter of rectangle is given by  2 ( l + b)

where l is length of rectangle and b is width of the rectangle

given that perimeter of rectangle is 274

so 2 (l+b)= 274

The remote interior angles of ∠1 are 34° and the right angle. The amount of m∠2 is 56°.

∠1 is an exterior angle because it is located outside the triangle. It has 2 remote interior angles. Remote interior angles are the angles with no shared vertex with the exterior angle. In this case, the remote interior angle of ∠1 is angle 34° and the right angle.

m∠1 can be measured by adding the remote interior angles:

m∠1 = 34° + 90°

m∠1 = 124°

Since m∠1 share a vertex with m∠2, then the total of both angles should be equal to 180° (a straight line). Hence:

m∠1 + m∠2 = 180°

Using the value of m∠1 known above, we can find the value of m∠2:

m∠1 + m∠2 = 180°

124° + m∠2 = 180°

m∠2 = 56°
