what is the solution to the system of equations y23x3 x 2

Answers

Answer 1

The Solution for the given system of equations is (-2) and [tex](\frac{5}{3})[/tex].

The given are linear equations as follow:
y = [tex]\frac{2}{3}x[/tex] + 3              .. ... ...(1)
and x  = -2.          .. .... ...(2)

We already know the first part of the solution (x) which is -2.  We can find the other part (y) by putting the value of equation (2) in equation (1).

By putting the values of x in equation (1), we get

y = [tex](\frac{2}{3})(-2)[/tex] + 3
y = [tex]\frac{-4}{3}[/tex] + 3

Taking the L. C. M of denominators which will be '3', we get:

y = [tex]\frac{-4 + 9}{3}[/tex]

y = [tex]\frac{5}{3}[/tex]

So the second part (y) of the solution of the given equation is [tex]\frac{5}{3}[/tex].

Hence, the overall solution to the given system of equation is [tex](-2, \frac{5}{3})[/tex].

Answers

Answer:

Q1. The sum of your hat size and shoe size is 54.

Q2. The correct answer is 101.

Q3. The correct answer is 6561.

Step-by-step explanation:

Q1. Let's call the size of your hat H and the size of your shoe S. You can set up the following equation based on the given information:

H = 2S

H = S + 18

Substituting the first equation into the second equation, we get:

2S = S + 18

S = 18

Then, substituting this value back into the first equation, we get:

H = 2S

H = 2 * 18

H = 36

The sum of your hat size and shoe size is S + H = 18 + 36 = 54.

Q2. The least 3-digit odd sum of two prime numbers is 101, which can be achieved by adding the two prime numbers 2 and 99. Both 2 and 99 are prime numbers, and their sum is 101, which is a 3-digit odd number.

What is a special segment?

Answers

The special segments of a triangle are median, altitude, perpendicular bisector, angle bisector, and mid-segment.

What is a special segment?

A line segment that establishes a special relationship with the existing segments of a geometrical shape is said to be a special segment.

Using this special segment, we can able to find the other characteristics of the geometry (a triangle or a circle, etc.)

Description about special segments:

The special segments in a triangle are:

1) Altitude 2) Median 3) Perpendicular bisector and 4) Angle bisector

Altitude: This line segment whose one end starts at one of the vertexes of the triangle and the other end is perpendicular to the opposite side of the triangle.

The point of intersection of three altitudes of a triangle forms an "Orthocenter".

Median: This line segment whose one end starts at one of the vertexes of a triangle and the other end meets at the midpoint of the opposite side.

The point of intersection of three medians of a triangle forms a "Centroid".

Perpendicular bisectors: These line segments whose ends bisect the two sides of the triangle perpendicularly.

The point of intersection of perpendicular bisectors of a triangle form a "Circumcenter".

Angle bisector: This line segment bisects the angle of the triangle and divides the angle into exactly two halves.

The point of intersection of angle bisectors of a triangle form an "Incenter".

We have one more special segment in a triangle i.e., a midsegment. This line connects two midpoints of opposite sides of a triangle and becomes parallel to the third side.

(Enter your answer to three decimal places.) flight hours/104

Answers

On solving the provided question we got to know that, the median value won't change if the greatest sample Observation is decreased to 1.3735.

What is median?

One of three ways to gauge central tendency is the median. The center position of a record is specified when describing it. A measure of central tendency is what this is. The mean, median, and mode are the three most frequently used indicators of central tendency.

The sum of all the values is divided by the total number of values, giving the mean value.

[tex]0.736 + 0.863 + 0.865 + 0.913 + 0.915 + 0.937 + 0.983 + 1.001 + 1.011 + 1.064 + 1.109 + 1.132 + 1.140 + 1.153 + 1.253 + 1.397 = 16.472\\16.472 /16 = 1.0295\\1.0295 is the mean value[/tex]

The number near the middle of the point is the median value. At the halfway point, there are two values.

[tex](1.001 + 1.011) / 2 = 1.006\\ 1.006 is the median value.[/tex]

As a result, the median value, which depicts the middle value of the numbers in the result, is less than the mean value, which depicts the real middle value of the numbers if they were equally distributed.

Their difference is that 1.0295 - 1.006 = 0.0235

1.397 observations make up the biggest sample. It may be made smaller by taking the number and removing the difference between the mean and median.

Consequently, there is a 0.0235-point difference between the mean and median.

Therefore;

[tex]1.397 - 0.0235 = 1.3735[/tex]

The median value won't change if the greatest sample Observation is decreased to 1.3735.

Answers

4.65 kg the mass of each item (assuming the bag's mass is negligible). (Sand density is 3.00 g/cm3, while the density of gold is 19.3 g/cm3)

Given that,

A gold statue that is perched on a pedestal with a weight-sensitive alarm is replaced by a thief using a bag of sand. The statue and the bag of sand have the exact same volume, 1.55 L.

We have to calculate the mass of each item (assuming the bag's mass is negligible). (Sand density is 3.00 g/cm3, while the density of gold is 19.3 g/cm3)

We know that,

Mass of gold = Volume × Density

= 1.55×1000 cc × 19.3

= 29915 grams

= 29.915 Kg

Mass of sand = 1.55×1000×3

= 4650g

= 4.65 Kg

Volume = 1.55 L

= 1.55 × 1000 cc

= 1550 cc

Mass = Volume × Density

Mass of gold = 1550 × 19.3

= 29915 grams

= 29.915 kg

Mass of sand = 1550 × 3

= 4650 grams

= 4.65 kg

Therefore, 4.65 kg the mass of each item (assuming the bag's mass is negligible). (Sand density is 3.00 g/cm3, while the density of gold is 19.3 g/cm3)

Unit of Conversion is a multi-step process involving multiplication or division by a numerical factor.

Given:

Speed of Adam = 13 feet per second

Speed of Stephanie = 199 feet in 17 seconds

Speed of Noah = 1 mile in 592 seconds

Speed of Katie = 878 feet in 1 minute

Now on converting all the units to one single unit,we get  

1 mile = 5280 feet

1 minute = 60 seconds

Speed of Adam = 13 feet per second

Speed of Stephanie = 199 feet in 17 seconds

                                 = [tex]\frac{199}{17}[/tex] feet per second

                                 = 11.705 feet per second

Speed of Noah = 1 mile in 592 seconds

Step-by-step explanation:

You want to fill a table using the given rules, then describe the relationship between the table values.

Pattern A

Starting with 100, you want to subtract 20 to get next terms:

  100

  100 -20 = 80

  80 -20 = 60

  60 -20 = 40

The next terms are 80, 60, 40.

Pattern B

Starting with 20, you want to subtract 4 to get next terms:

  20

  20 -4 = 16

  16 -4 = 12

  12 -4 = 8

The next terms are 16, 12, 8.

Relationship

Looking at second terms, we can determine which description is true:

  80 -80 = 0 ≠ 16 . . . . . the description "subtract 80" fails

  80/5 = 16 . . . . . . . . . . the description "divide by 5" works

(7a + 10b) - (4a - 6b)

= 7a + 10b - 4a + 6b

On combining like terms we get,

(7a - 4a) + (10b + 6b)

= 3a + 16b

Therefore, (7a + 10b) − (4a − 6b) = 3a + 16b

b) Given expression :

−5x + 8y + 2x − 3y

On combining like terms we get,

-5x + 2x + 8y - 3y

= (-5x + 2x) + (8y - 3y)

= -3x + 5y

therefore, −5x + 8y + 2x − 3y  = -3x + 5y

c) Given expression:

x - 4 ≤ -1

⇒ x ≤ -1 + 4

⇒ x ≤ 3

Graph of the function is given below:

If other factors are held constant, which set of sample characteristics is most likely to lead a researcher to reject a null hypothesis stating that µ = 80? a. M = 85 and s2 = 9 b. M = 90 and s2 = 9 c. M = 85 and s2 = 18 d. M = 90 and s2 = 18

Answers

If other factors are held constant, which set of sample characteristics is most likely to lead a researcher to reject a null hypothesis stating that µ = 80 then s2 = 18 and C. M = 85

The standard deviation (s2) is a measure of the variability of the sample data, while the mean (M) is a measure of the central tendency. The higher the mean and the higher the standard deviation, the more likely it is that the null hypothesis will be rejected. Therefore, the set of sample characteristics that is most likely to lead to a rejection of the null hypothesis is M = 85 and s2 = 18.

A set of n = 15 pairs of scores (X and Y values) produces a correlation of r = 0.20. If each of the X values is multiplied by 2 and the correlation is computed for the new scores, what value will be obtained for the new correlation?​

Answers

The new value of  correlation will be 0.20.

What is correlation?

The strength and direction of a relationship between two or more variables are described by the statistical measure of correlation, which is given as a number. However, a correlation between two variables does not necessarily imply that a change in one variable is the reason for a change in the values of the other.

Given that the size of the sample is n = 15.

The correlation is r = 0.20.

The degree of the association between two measurement variables is quantified and determined via correlation analysis. Regression aims to describe the relationship as an equation at the same time. For patients who visit an emergency room (ED), for instance, we could use correlation and regression.

The correlation coefficient is unaffected by the change of origin.

Thus r = 0.20.

Which is always true about a trapezoid?

Answers

Answer: They always have one pair of parallel lines.

Step-by-step explanation:

In Original Source 2, "Development and initial validation of the Hangover Symptoms Scale: Prevalence and correlates of hangover symptoms in college students," one of the questions was how many times respondents had experienced at least one hangover symptom in the past year. Table 3 of the paper (page 1,445) shows that out of all 1,216 respondents, 40% answered that it was two or fewer times. Suppose the researchers are interested in the proportion of the population who would answer that it was two or fewer times. Can they conclude that this population proportion is significantly less than half (50% or 0.5)? Go through the four steps of hypothesis testing for this situation for women only. Use appropriate software or a calculator to find the standard deviation and the test statistic. (Round your standard deviation to three decimal places and your test statistic to two decimal places.) Test Statistic?

Answers

Only twice or less, according to 40% of respondents. Suppose the researchers are curious about the percentage of the population that would respond that it was two or less times, in which case the test statistic would be -0.208 and the standard deviation would be 0.048.

H0: The population proportion of women who have experienced two or fewer hangover symptoms in the past year is equal to or greater than 0.5.

Ha: The population proportion of women who have experienced two or fewer hangover symptoms in the past year is less than 0.5.

Set the alpha level

α = 0.05

Calculate the test statistic

n = 618 (women only)

p = 0.4 (from Table 3)

Standard Deviation = sqrt[p*(1-p)/n]

Standard Deviation = sqrt[0.4*(1-0.4)/618]

Standard Deviation = 0.048

Test Statistic = (0.4 - 0.5) / 0.048

Test Statistic = -0.208

Step 4: Make a decision

Since the test statistic (-0.208) is less than the alpha level (0.05), we reject the null hypothesis and conclude that the population proportion of women who have experienced two or fewer hangover symptoms in the past year is less than
