Answer:

Step-by-step explanation:

1. 3x + 2y - 2x + y + 12 is equivalent to x + 3y + 12

2. 4y + 3y + 3x - 6y - 10 - 2 is equivalent to 3x + y - 12

3. x + 3y + 2x - 3x + 7 + 5 is equivalent to 3y + 12

4. I do not know unfortunately

Answer:

See attached image

Step-by-step explanation:

To solve this, first simplify the compound expressions - the ones with multiple x, y terms and see which of the other expressions matches the simplified expression

I will tell you how to solve one of the more complex expressions; the technique is the same for the rest

Let's take the very last expression
4y + 3y + 3x - 6y -10 - 2

To simplify,

group like terms:

=(4y + 3y - 6y) + 3x +(-10 -2)

= y + 3x - 12

Rewriting with x before y gives
3x + y - 12

and there is a matching 3x + y - 12

4y + 3y + 3x - 6y -10 - 2   ⇔  3x + y - 12

Based on the information, we can infer that celebrity quotes include percentages to give their words more credibility.

To identify the meaning of famous quotes we must read them carefully and identify the key words to know the deep meaning of these sentences. According to the above, the meaning would be:

The first means that geniuses work harder than people think because their genius is generally related to their creativity. However, he points out that it is 99% work.

The second means that to be successful you have to fail many times. In this case, it refers to the fact that success is made up of 99% of failed attempts and the 100th attempt is the one that is successful.

The third refers to the fact that if we do not try to carry out a challenging activity, we are losing 100% of the possibilities of achieving it. On the contrary, if we try at least we will learn to do it.

The fourth refers to the fact that sometimes people exceed their capacity to carry out an action and that extra 10% is what allows them to make a difference.

Answer:

the answer is straight through the origin

Answer:

A certain number is added to 6

After 50 seconds the runners will meet if the graph shows the distance covered by two runners in a race with respect to time option (C) is correct.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

\(\rm m =\dfrac{y_2-y_1}{x_2-x_1}\)

We have two lines shown on the coordinate plane.

As we know,

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

Both lines have a positive slope.

From the graph, we can see the intersection point of the lines is at (50, 400)

50 seconds, as that is where the lines cross, where the two runners collide.

Thus, after 50 seconds the runners will meet if the graph shows the distance covered by two runners in a race with respect to time option (C) is correct.

Answer: 7.5 Batches

Step-by-step explanation:

Plug 45 in for Y:

45/6=6x/6

Isolate variable (divided by 6)

X=7.5

The required number of batches of cookies corresponding to the 45 ounces is 7.5 batches. Option C is correct.

Given that,

The number of ounces of chocolate chips per batch of cookies can be represented with the equation y = 6x, where y represents ounces of chocolate chips and x represents batches of cookies.

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,
Given proportionality,
y = 6x
Put y = 45
x = 45 / 6
x = 7.5

Thus, the required number of batches of cookies corresponding to the 45 ounces is 7.5 batches. Option C is correct.

Step-by-step explanation:The most basic Equation for Circles is Circumference = Diameter x Pi.

Answer:

No

Step-by-step explanation:

The first coordinate is x and the second is y so that makes the equation 3=6 which is not true.

Part A: To calculate the measures of center, we can find the median and the mean for each school.

For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.

To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.

For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.

To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):

18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.

Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.

The measures of center for Seaside School are: median = 15, mean ≈ 15.9.

Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.

For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.

To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.

For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.

To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.

Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.

The measures of variability for Seaside School are: range = 15, IQR = 6.

Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.

Answer:

-x-12

Step-by-step explanation:

Given:

\(\displaystyle \large{|x-(-12)| \quad (x < -12)}\)

Simplify:

We know that negative times negative equals positive, therefore:

\(\displaystyle \large{|x+12| \quad (x < -12)}\)

Modulus Property:

\(\displaystyle \large{|x+a| = \begin{cases} x+a \quad (x \geq -a) \\ -x-a \quad (x < -a) \end{cases}}\)

Therefore, since given interval is x < -12:

\(\displaystyle \large{|x+12| \quad (x < -12) = -x-12}\)

Hence, simplified expression is -x - 12

Answer:

the answer is B (x and y have a weak, positive correlation)

Give the person above me brainlyest for helping!

Step-by-step explanation:

The coefficient of correlation for the given data of x and y is 0.78.

x and y have a strong, positive correlation

A correlation coefficient is a number between -1 and 1 that tells you the strength and direction of a relationship between variables. In other words, it reflects how similar the measurements of two or more variables are across a dataset.

Here, given values of x and y

x   1    2    3   4   5    6

y   3   4    9   7    2    18

xy  3   8   27  28 10  108

x²   1   4    9    16   25   36

y²   9  16  81  49  4  324

∑x = 21,  ∑y = 43,  ∑xy = 194, ∑x² = 91, ∑y² = 483, n = 6

Now, Correlation between x and y

r = (n∑xy - ∑x.∑y)/ √[{n∑x²- (∑x)²}{n∑y² - (∑y)²}]

r = ( 6 X 194 - 21 X 43 ) / √[ {6 X 91 - (21)²}{ 6 X 483 - (43)²}]

r = ( 1164 - 903) / √( 546 - 441)(2898 - 1849)

r = 261 / √ 105 X 1049

r = 261 / √110145

r = 261 / 331.88

r = 0.78

Thus, The coefficient of correlation for the given data of x and y is 0.78.

x and y have a strong, positive correlation

Answer:

graph the figures B

Step-by-step explanation:

Answer:

  (d)

Step-by-step explanation:

You want to identify the stem and leaf plot for the 16 scores listed. Their minimum is 0.

A typical stem and leaf plot lists the number of tens in a value at the left margin (the stem), then units digits (in order, least to greatest) of the values with that number of tens.

For example, the scores 0 and 5 both have 0 tens, so would be plotted as ...

  0 | 0 5

where the leftmost 0 is the "stem" and the right two digits, 0 and 5, are the "leaves".

The plot will have as many leaves as there are values in the data set.

The two scores less than 10 are 0 and 5, so the first line of the stem-and-leaf plot will be ...

  0 | 0 5 . . . . . . . . . eliminates choices B and C

There are 16 scores in the data set, so the plot will have a total of 16 leaves. (eliminates choice A).

The correct stem-and-leaf plot is choice D:

0 | 0 5

1 | 1 5 5 5

2 | 0 0 0 0 3 6

3 | 1 4 9 9

Key 1|1 = 11
