Carolyn made an error in her work because she did not correctly distribute the negative in Step 3.

A system of equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point of the intersection.

You can solve a system of equations by the adding or substitution methods. In the addition method, you eliminate a variable, on the other hand, in the substitution method you replace a variable for the other.

The question gives:3x-2y=7 (1)y=x+2The question shows that Carolyn applies the substitution method because she replaces the variable y (equation 2) in equation 1. See the given step 2.

3x – 2y = 7

3x – 2(x + 2) = 7

3x – 2x - 4 = 7 - here it is the mistake. (Carolyn did not correctly distribute the negative).

Step-by-step explanation:

The equation that would help the mathematician model the surface area of a square piece of paper as it was repeatedly cut is \(y = 36 \times \frac{1}{2}^x\)

Option D is the correct answer.

We have,

In this equation, the variable x represents the number of times the square is cut in half, and y represents the surface area of the square.

As x increases, the exponent of 1/2 decreases, causing the value of y to decrease.

This exponential decay accurately represents the idea that the surface area becomes less and less but never reaches zero units²

Thus,

The equation that would help the mathematician model the surface area of a square piece of paper as it was repeatedly cut is \(y = 36 \times \frac{1}{2}^x\).

The correct equation that would help model the surface area of a square piece of paper as it is repeatedly cut in half is:  \(\(y=36(\frac{1}{2})^x\)\)

As the square is cut in half, the side length of the square is divided by 2, resulting in the area being divided by \(\(2^2 = 4\)\).

Therefore, the equation \(y=36(\frac{1}{2})^x\)\)accurately represents the decreasing surface area of the square as it is repeatedly cut in half.

and, \(\(y=x^2+4x-16\)\)is a quadratic equation that does not represent the decreasing nature of the surface area.

and, \(\(y=-25x^2\)\) is a quadratic equation with a negative coefficient.

and, \(\(y=9(2)^x\)\)represents exponential growth rather than the decreasing nature of the surface area when the square is cut in half.

Answer:

16%

Step-by-step explanation:

To calculate this we first need to calculate the probability of Mario scoring for every individual shot that he takes. Since he makes 2 goals for every 5 shots on average, we simply divide these numbers to get the probability of a goal per shot.

2 / 5 = 0.4  ...multiply by 100 to get percentage value

0.40 * 100 = 40%

We see that the probability of scoring a goal per shot is 40%. Now we need to multiply this probability twice to get the probability of scoring 2 consecutive goals in two shots.

0.40 * 0.40 = 0.16  ... multiply by 100 to get percentage value

0.16 * 100 = 16%

Answer:

16%

Step-by-step explanation:

I know that 2/5 = 0.4 or 40%

and 0.4 x 0.4 = 0.16

or 16%

basically what the other one said, without words

A distribution in which all the values have the same frequency is called a rectangular distribution. This type of distribution is also known as a uniform distribution ,

because the probability of any given value occurring is equal to every other value in the distribution. Rectangular distributions can be represented graphically by a flat, straight line that runs across the entire range of values, indicating that each value has an equal chance of occurring.

This type of distribution is commonly used in probability and statistics, as well as in financial analysis and risk management. While rectangular distributions are relatively simple and easy to understand, they may not always accurately reflect the true nature of a dataset, particularly if there is a significant amount of variation or outliers.

It is important to note that bimodal and standard distributions have different properties and are not the correct terms for this scenario. Bimodal refers to a distribution with two distinct peaks, while standard distribution typically refers to a normal distribution with a mean of 0 and a standard deviation of 1.

Let's denote the number of slices with both pepperoni and mushrooms as $x$. We are given that there are 6 slices with pepperoni and 10 slices with mushrooms.

Since every slice has at least one topping, the total number of slices is 12. We can break down the slices into the following categories:

Slices with only pepperoni: 6 slices

Slices with only mushrooms: 10 slices

Slices with both pepperoni and mushrooms: $x$ slices

Slices with neither pepperoni nor mushrooms: 12 - (6 + 10 + x) slices

We know that the total number of slices is 12, so we can write an equation:

6 + 10 + x + (12 - (6 + 10 + x)) = 12

Simplifying the equation, we have:

16 + x - (16 + x) = 12

The terms with "x" cancel out, and we're left with:

0 = 12

The company ought to anticipate 96 complaints at the conclusion of week 8 based on the line of best. (Option B).

To anticipate the number of complaints at the conclusion of week 8, we got to utilize the line of best fit condition, which speaks to the relationship between the weeks and the number of complaints.

Expecting that we have as of now calculated the line of best fit and determined that it may be a straight relationship, we are able utilize the slope-intercept frame of a line:

y = mx + b

where:

y = the anticipated number of complaints at the conclusion of week 8

m = the slant of the line of best fit

x = 8 (since we need to predict the number of complaints at the conclusion of week 8)

b = the y-intercept of the line of best fit

We will calculate the slant and y-intercept utilizing the given information:

Incline (m): To discover the slant of the line of best fit, we got to utilize the equation:

m = (n∑xy - ∑x∑y) / (n∑x^2 - (∑x)^2)

where:

n = the number of information focuses (in this case, 6 weeks)

∑xy = the entirety of the items of the x and y values

∑x = the whole of the x values

∑y = the whole of the y values

∑x^2 = the entirety of the squared x values

Utilizing the information given within the table, ready to calculate:

∑xy = (1225) + (2205) + (3187) + (4169) + (5147) + (6130) = 2859

∑x = 1 + 2 + 3 + 4 + 5 + 6 = 21

∑y = 225 + 205 + 187 + 169 + 147 + 130 = 1063

∑x^2 = 1^2 + 2^2 + 3^2 + 4^2 + 5^2 + 6^2 = 91

Utilizing these values, ready to calculate the incline:

m = ((62859) - (211063)) / ((6*91) - (21^2)) = -17.5

Y-intercept (b): To discover the y-intercept of the line of best fit, we will utilize the equation:

b = y - mx

where:

y = the cruel of the y values

m = the slant of the line of best fit

x = the cruel of the x values

Utilizing the information given within the table, able to calculate:

y = (225 + 205 + 187 + 169 + 147 + 130) / 6 = 177.17

x = (1 + 2 + 3 + 4 + 5 + 6) / 6 = 3.5

Utilizing these values, ready to calculate the y-intercept:

b = 177.17 - (-17.5 * 3.5) = 235.92

Presently that we have the incline and y-intercept, we are able to utilize the condition for a line to anticipate the number of complaints at the conclusion of week 8:

y = -17.5x + 235.92

where x = 8 (since we need to anticipate the number of complaints at the conclusion of week 8)

y = -17.5(8) + 235.92

y = 96.42

The point farthest from the plane is (0, -31/3, 10/3).The point farthest from the plane is the one that lies on the intersection of the plane and the normal vector pointing in the direction of the center of the sphere.

In this case, the center of the sphere is at (0, 0, 10) and the normal vector of the plane is (1, 2, 0).

To find the point of intersection, we solve for x and y in terms of z from the equation of the sphere:

x^2 + y^2 = 10 - z

Substituting this into the equation of the plane, we get:

x + 2y + 72 = 0

Substituting x^2 + y^2 = 10 - z, we get:

10 - z + 2y + 72 = 0

Simplifying, we get:

y = (-z - 82)/2

Substituting y into x^2 + y^2 = 10 - z, we get:

x^2 + (-z - 82)^2/4 = 10 - z

To find the point farthest from the plane, we want to maximize z. Taking the derivative of the above equation with respect to z and setting it equal to zero, we get:

z = 10/3

Substituting this value of z back into the equations for x and y, we get:

x = 0, y = -31/3, z = 10/3

Therefore, the point farthest from the plane is (0, -31/3, 10/3).

The letter W has one vertical line of symmetry that divides it into two identical halves. However, it does not have any rotational symmetry of order 2 or higher because there is no way to rotate the letter by a certain angle and have it look the same as before the rotation. Therefore, the answer is (b) 1, as W has only one line of symmetry and no rotational symmetry of order 2 or higher. In other words, if you rotate the letter by any angle other than 0 or 180 degrees, it will look different than before the rotation.

Answer:

The volume of Cone B is twice the volume of Cone A.

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h  where r is the radius and h is the height.

Cone A

d = diameter

r = radius

h = height

V = 1/3 pi r^2 h

Cone B

The diameter is double the diameter of A.

2d  so the radius is 2r

The height is half the height of A.

1/2 h

Substitute into the equation for volume.

V = 1/3 pi ( 2r)^2 (1/2 h)

V = 1/3 pi (4r^2) (1/2h)

V = 1/3 pi 2r^2 h

The volume of Cone B is twice the volume of Cone A.

Answer:

Cone B has a greater volume.

Step-by-step explanation:

Cone B has the greatest volume.

The volume of a cone is calculated using the following formula:

\(\boxed{\bold{\tt{Volume\: of\:cone = \frac{1}{3}\pi*r^2h}}}\)

where:

For Cone A.

\(\boxed{\bold{\tt{Volume\: of\:cone\: (A)= \frac{1}{3}\pi*r^2h}}}\)

For Cone B

In this case, the radius of Cone B is double the radius of Cone A, and the height of Cone B is half the height of Cone A. This means:

radius(r)=2r

height(h)= \(\tt{\frac{1}{2}*\frac{h}{2}}\)

\(\boxed{\bold{\tt{Volume\: of\:cone\: (B)= \frac{1}{3}\pi*(2r)^2*\frac{h}{2}}}}\)

\(\boxed{\bold{\tt{Volume \: of\:cone (B)= 2*\frac{1}{3}\pi*r^2h}}}\)

\(\boxed{\bold{\tt{Volume(B) =2*Volume\: of\:cone(A)}}}\)

Since the volume of cone B is twice the volume of Cone A.

Therefore, Cone B has a greater volume.
