Answer:

8y-36x=16

Step-by-step explanation:

Dialating means you are multiplying or dividing. Since 2 is positive you multiply everything by 2, usually it would be coordinates, like if it said dialate (2,4) by 6 we would get (12, 24), but I didn't really want to have to solve the equation for the coordinates so try the answer I wrote, if not I am so so so sorry but at least now you know what dialating means.

Answer:

3rd option

38, 45, 80, 210, 360

Step-by-step explanation:

The correct order from least to greatest for your options is л 7л < 38° < 4 < 80° < 6 < 2x, the correct option is A.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

The options A,B,C and D

Now,

To order numbers and angles from least to greatest, you need to compare their values and arrange them in ascending order. For numbers, you can use a calculator1 or a number sorter2 to help you. For angles, you need to measure their size in degrees using a protractor3 and then classify them as acute (< 90°), right (= 90°), obtuse (> 90°) or reflex (> 180°) angles4. The smallest angle is an acute angle and the largest angle is a reflex angle.

Therefore, by algebra the answer will be л 7л < 38° < 4 < 80° < 6 < 2x

Answer:

30 cm²

Step-by-step explanation:

solve for area of rectangle: 12 x 4 = 48 cm²

solve for area of triangle: 9 x 4= 36 / 2 = 18 cm²

subtract: 48- 18 = 30cm²

The cluster in the data is the most circles together in the middle ( data points in the range 6 ≤ y ≤ 8))

"It is a graph that presents the relationship between two variables in a data-set."

"The data points in a scatter plot form distinct groups known as clusters."

For given question,

We have been given the scatter plot.

We know, a cluster is a group of points that follow the same general pattern.

If we observe the graph,

The data points in the range (6 ≤ y ≤ 8) or (7 < x < 9) form a cluster.

This means, the cluster in the data is the most circles together in the middle (data points in the range 6 ≤ y ≤ 8)

Step-by-step explanation:

From the line plot, the length of wood measuring atleast 1/2 in length include :

Piece with length 1/2 and pieces with length 2/3

Number of pieces with length 1/2 feets = 4

Number of pieces with length 2/3 feets = 2

Pieces with atleast 1/2 feet length = 4 + 2 = 6

Answer:

Dvds cost 12 games cost 19.

Step-by-step explanation:

Put the amount of dvds and video games into an equation and assign variables.

3x+2y=74

5x+2y=98

You can solve multiple ways, although I'll do graphing for this equation.

After graphing, you get 2 lines that intersect. The point of intersection is 12,19 meaning that a dvd is 12 (x) and a video game is 19 (y)

DVD = x

video games = y

3 DVD + 2 video games = $74

3x + 2y = 74

5 DVD + 2 video games = $98

5x + 2y = 98

We can easily use eliminations by changing one of the equations, with all variables becoming negative signs, in order to eliminate the variable y.

-(3x + 2y = 74)

-3x -2y = -74

Now add both equations toegther (in order to eliminate the avriable y and solve for x).

5x + 2y = 98

-3x -2y = -74

____________

2x + 0y = 24

2x = 24

x = 12 [A DVD costs $12]

Plug that value for x into one of the equations:

5x + 2y = $98

5(12) + 2y = 98

60 + 2y = 98

2y = 38

y = 19 [A video game costs $19]

Step-by-step explanation:

The most likely to have the greatest variability is,

⇒ The height of all students at West Middle school.

A Mathematical expression is defined as collection of the numbers, variables and functions by using operations like addition, subtraction, multiplication, and division

Now, We know that;

Greatest variability is large spectrum of possibilities.

Hence, We get;

The costs of candy from vending machine are going to be about the same price because they are all candy, so that does not vary much more.

And, The age of all the students in the sixth grade is going to be about the same because they are in the same grade.

Since, The number of days in a month is usually 31 or 30, so that also does not vary much.

This means, it has to be the height of all the students at West Middle school because it is a middle school so there are 3 different grades each having many students. This means that it will have the greatest variability.

Thus, The most likely to have the greatest variability is,

⇒ The height of all the students at West Middle school

Answer:

Step-by-step explanation:

First, decide if this situation describes a combination or a permutation by looking at the significance of order. Consider a specific example where the letters A – C represent the 3 different pitchers. The pitching order A, B, C is different from the pitching order B, C, A because the players will be pitching at different times. Therefore, this situation describes a permutation. Use the formula for finding the number of permutations when the number of pitchers is 3, so n = 3, and all 3 are taken at a time, so r = 3 as well.

Answer/Step-by-step explanation:

To find out the mistake of the student, let's find the min, max, median, Q1 and Q3, which make up the 5 important values that are represented in a box plot.

Given, {2, 3, 5, 6, 10, 14, 15},

Minimum value = 2

Median = middle data point = 6

Q1 = 3 (the middle value of the lower part of the data set before the median)

Q3 = 14 (middle value of the upper part of the data set after the median)

Maximum value = 15

If we examine the diagram the student created, you will observe that he plotted the median wrongly. The median, which is represented by the vertical line that divides the box, ought to be at 6 NOT 10.

See the attachment below for the correct box plot.

Me I don't know the answer teacher am waiting for the correction

The required probability of both A and B occurring is 0.3827.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

The conditional probability of A provided B has happened, so it can be written as follows:

P(B|A) = P(A and B)/P(A)

Given that P(A) = 0.43 and P(B|A) = 0.89

We can use the formula of conditional probability:

P(A and B) = P(B|A) × P(A)

Substitute the given values in the above formula,

P(A and B) = 0.89 × 0.43

P(A and B) = 0.3827

Therefore, the probability of both A and B occurring is 0.3827.
