According to given data GR(x) * GR(y) = 3 * 2m - 5

The given monomial is P(x;y) = -mx^3m-1 * y^2m-7, and it is known that GA(P) = 17.

We need to find the values of GR(x) and GR(y), which are the degrees of the monomial with respect to x and y, respectively.

Using the formula GA(P) = GR(x) + GR(y), we get GR(x) + GR(y) = 17.

Now, we can write the monomial as P(x;y) = (-m) * x^(3m-1) * y^(2m-7).

Therefore, GR(x) = 3m-1 and GR(y) = 2m-7.

Multiplying these two values, we get GR(x) * GR(y) = (3m-1) * (2m-7) = 6m^2 - 23m + 7.

Hence, the final answer is GR(x) * GR(y) = 6m^2 - 23m + 7.

There is no any fraction of Pizza left for other toppings, so the required space for other toppings is Zero.

Fractions are used to represent portions of a full or collection of items. There are two parts to every fraction. The number which is at the top of the line is referred to as the numerator. It specifies the number of equal pieces taken from the overall amount or collection. Figure below the line is referred to as the denominator. It shows the number of identical items in a group or the total number of equal parts in a whole.

Ed place mushrooms on Pizza = 5/12

Ed place onions on Pizza = 7/12

Total Fraction of Pizza left = 1 - (5/12 + 7/12)

If each basket contains the same number of eggs and there are at least 4 eggs in each basket, Jenny put 3 red eggs in each of 6 baskets, and 4 orange eggs in each of 6 baskets.

Let's call the number of eggs in each basket "x." We know that Jenny placed a total of 18 red eggs, so the number of baskets with red eggs can be represented as 18/x. Similarly, the number of baskets with orange eggs can be represented as 24/x.

Since we know that each basket contains at least 4 eggs, we can set up the inequality 4 ≤ x.

Now we can use this information to set up an equation:

18/x + 24/x = total number of baskets

Simplifying this equation, we get:

42/x = total number of baskets

But we also know that the total number of baskets is an integer (you can't have a fraction of a basket), so x must be a factor of 42.

The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. But we also know that each basket must contain at least 4 eggs, so we can eliminate 1, 2, and 3 as possible values of x.

Therefore, the possible values of x are 6, 7, 14, 21, and 42. But we also know that there are 18 red eggs and 24 orange eggs, so x must be a factor of both 18 and 24.

The common factors of 18 and 24 are 1, 2, 3, and 6. Therefore, the only possible value of x is 6.

open brackets:

\(16d + 23 = 14d - 28\)

collect d terms together:

\(16d - 14d = - 28 - 23 \\ 2d = - 51 \\ d = - 25.5\)

The function that represents the data in the table is 3x²+2. The correct answer is B.

The quadratic function is shown in the data table.

We must ascertain the function's equation.

The quadratic equation's generic form is

Let's replace the general form with the three coordinates (1,5, (2,14), and (3,29).

We therefore have;

a+b+c =5——— (1)

4a+2b+c= 14——— (2)

9a+3b+C =29------(3)

When (2) is subtracted from (1), we have;

9= 3a+b(4)

Subtracting (3) from (2) gives us;

15= 5a +b(5)

Subtracting (5) from (4) gives us;

6= 2a

3= a

As a result, the value of an is 3. When we replace this value in equation (4), we obtain;

3(3)+b= 9

b= 0

When a = 3 and b = 0 are substituted in equation (1), we obtain;

a+b+c =5

3+0+c=5

c=2

As a result, c has a value of 2.

As a result, when we substitute a = 3, b = 0, and c = 2 in the quadratic equation's general form y =ax²+bx+c, we obtain;

3x²+2

Consequently, the function that symbolizes the information in the table is 3x²+2

The m and b into slope-intercept form results in the equation y = 3x + 70

You need the y-intercept and the rate of change in order to write the equation of a line (slope). You can create your equation by substituting these values into the slope-intercept form of a line (y = mx + b).

You already know b because there are initially 70 gallons of water in the tank on Saturday. You must write two data points using the information provided in the question in order to determine m.

The number of gallons is the dependent variable, and time is the independent variable because the amount of water in the tank is dependent on how long Lena has been filling it. This indicates that the information should be presented in the form (time, gallons).

On Saturday at time = 0, there are 70 gallons, hence the data point is (0, 70). The tank is full (400 gallons) after 1 hour and 50 minutes, which is 60 + 50 = 110 minutes, so another data point is (110, 400). Using the slope formula, determine the rate of change as follows:

(400-70)/(110-0)

= 330/110

Approximately 68% of the cases in a normal distribution are between 0.5 standard deviations above and below the mean.

To find the percentage of cases that are between 0.5 standard deviations above and below the mean, we can add these two probabilities:

34% + 34% = 68%

The normal distribution, also known as the Gaussian distribution or the bell curve, is a probability distribution that is widely used in statistics, science, and engineering. A bell-shaped curve that is symmetrical around the mean value best describes the distribution. The distribution's mean, median, and mode are all equal, and the standard deviation defines the curve's width.

Height, weight, IQ, and measurement mistakes are only a few examples of the numerous random variables and natural phenomena that follow the normal distribution. In addition, the central limit theorem predicts that regardless of the underlying distribution of the variables themselves, the total or average of several independent random variables with similar distributions will converge to a normal distribution. Because of this characteristic, the normal distribution is a key idea in inferential statistics and hypothesis testing.

Carla is to select 5 fruit-flavored candies from a bowl containing 6 apple, 5 banana, and 4 cherry candies. She wants to know how many possible combinations of candies can Carla select. We need to determine the number of possible combinations of candies Carla can select. This can be done by applying the formula for combinations:  The formula for combinations is given as: `nCr

= (n!)/ (r! × (n - r)!)`

where n is the total number of items, and r is the number of items chosen at a time. Since Carla wants to select 5 fruit-flavored candies from a bowl containing 6 apple, 5 banana, and 4 cherry candies, we have n

= 6 + 5 + 4

= 15 and r

= 5.

We can calculate the number of possible combinations of candies Carla can select as follows:`nCr

= (n!)/ (r! × (n - r)!)` `

= (15!)/ (5! × (15 - 5)!)` `

= (15 × 14 × 13 × 12 × 11)/(5 × 4 × 3 × 2 × 1)`

What are similar triangles?

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the triangle be ABC and ADE

The triangles ΔABC ≅ ΔADE

Now , Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

So , the ratio of the sides will be

AD / AB = AE / AC

Substituting the values in the equation , we get

14 / 20 = x / 33

Multiply by 33 on both sides of the equation , we get

The value of x = ( 14 x 33 ) / 20

The value of x = 462 / 20

The value of x = 23.1

Therefore , the value of x is 23.1

Hence, x is orthogonal to any vector in W, and hence x is in W^⊥

For any scalar c, u^T (cv) = c(u^Tv)

True. This follows from the distributive property of matrix multiplication and the fact that scalar multiplication is commutative.

Let u and v be non-zero vectors: If the distance from u to v is equal to the distance from u to -v, then u and v are orthogonal.

True. This statement can be restated as saying that u lies on the perpendicular bisector of the line segment connecting v and -v. Since the perpendicular bisector is a line perpendicular to this line segment, it follows that u is orthogonal to both v and -v, and hence orthogonal to their sum, which is the zero vector.

For square matrix A, vectors in R(A) are orthogonal to vectors in N(A).

True. The range of a matrix A consists of all vectors b that can be expressed as b = Ax for some vector x, whereas the null space of A consists of all vectors x such that Ax = 0. If v is in R(A) and w is in N(A), then v = Ax for some x, and we have w^T v = w^T Ax = (A^T w)^T x = 0, since A^T w is in N(A) by the definition of the null space. Hence, v is orthogonal to w.

v^Tv = Ilvll^2.

True. This follows from the definition of the Euclidean norm, which is given by ||v|| = sqrt(v^T v). Hence, ||v||^2 = v^T v.

If vectors v1,....,vp span subspace W and if x is orthogonal to each vj for j = 1,.....,p, then x is in W^⊥.

True. Let v1,....,vp be a basis for W, and let x be orthogonal to each vj. Then, any vector w in W can be expressed as w = c1v1 + ... + cpvp for some scalars c1,....,cp. Since x is orthogonal to each vj, we have x^T w = c1 x^T v1 + ... + cp x^T vp = 0. Hence, x is orthogonal to any vector in W, and hence x is in W^⊥.

We know that 70% of the socks in the drawer are black, which means that in a random selection of 10 socks, we would expect to see around 7 black socks on average.

The dot plot shows the number of black socks in 10 trials of the number generator. We can see that the number of black socks varies from 0 to 10, with some frequencies being higher than others.

Without knowing the exact frequencies or probabilities, we can see that the dot plot does not appear to be centered around 7 black socks, which is what we would expect from a fair number generator. However, it is difficult to determine whether the deviations from 7 are statistically significant or not, without more information.

The only equation that follows what it says.

The missing length of the triangle can be found using the Pythagorean Theorem which states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We can use the formula c² = a² + b² where c is the hypotenuse, a is the opposite side and b is the adjacent side.

To find the missing length, we can rearrange the formula to solve for b: b² = c² - a². Substituting the given values,

we have: b² = (0.5)² - (0.3)².

Simplifying the equation, we get: b² = 0.16.

Taking the square root of both sides, we get: b = 0.4 cm.
