Answer:

X=1

Step-by-step explanation:

reverse multiplication -

7=4+3x

we know one value so we just isolate the 3x

7-4=3, meaning that 3x has to be equal to 3.

Then we just do 3/3=1 so therefore x=1

Also if you wanna check it then you can plug x=1 into the equation.

4+3*x or 1=4+3=7

Jacinta says that the product of a rational number and an irrational number is always irrational her claim is wrong.

A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.

Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers. Decimal notation is the term used to describe the method of representing numbers in the decimal system.

Given that Jacinta says that the product of a rational number and an irrational number is always irrational.

Her statement is incorrect because if 0 a rational number is multiplied with the π which is irrational then the result will be 0 which is rational.

Therefore, Jacinta's claim is wrong.

Both the interquartile range (IQR) and the range indicate that Bus 18 is the more consistent option. Its IQR of 16 and range of 16 are both smaller than the corresponding values for Bus 47, implying that the travel times of the students on Bus 18 are more consistent and have less variability.

To determine which bus is the most consistent, we can compare the measures of variability provided for each bus, namely the interquartile range (IQR) and the range.

The IQR is a measure of spread that represents the range of the middle 50% of the data. It is calculated by subtracting the first quartile (Q1) from the third quartile (Q3) of a dataset. The IQR provides information about the spread of the central portion of the data, ignoring outliers.

Looking at the given information:

For Bus 18:

IQR = 16

For Bus 47:

IQR = 24

Comparing the IQRs, we can conclude that Bus 47 has a larger IQR of 24, while Bus 18 has a smaller IQR of 16. A larger IQR indicates a greater spread or variability in the data, suggesting that the travel times of the students on Bus 47 vary more widely than those on Bus 18. Therefore, Bus 18 is more consistent or has less variability in travel times based on the IQR.

Additionally, we can also consider the range, which is the difference between the maximum and minimum values in a dataset. The range provides a measure of the total spread of the data, including the extreme values.

For Bus 18:

Range = 16

For Bus 47:

Range = 24

Comparing the ranges, we see that Bus 47 has a larger range of 24, while Bus 18 has a smaller range of 16. Similar to the IQR, a larger range indicates a wider spread or variability in the data, whereas a smaller range suggests less variability. Therefore, based on the range as well, Bus 18 is more consistent or has less variability in travel times compared to Bus 47.

In summary, both the interquartile range (IQR) and the range indicate that Bus 18 is the more consistent option. Its IQR of 16 and range of 16 are both smaller than the corresponding values for Bus 47, implying that the travel times of the students on Bus 18 are more consistent and have less variability.

So for any designated number 1-6 = (p) = 1/6

Step-by-step explanation:

When there is just one event there will always be 6 possible outcomes for one number, so the number of favorable outcomes will be divided by 6 to get your probability.

A) 2 can occur 1 time. P(2) = 1/6

B) there are 3 even numbers. P(even) = 3/6 = 1/2

C) 4 or 5 are 2 possible outcomes. P(4,5) = 2/6 = 1/3

D) there are 3 odd numbers. P(odd) = 3/6 = 1/2

So for any designated number 1-6 = (p) = 1/6

Answer:

38 7/18

Step-by-step explanation:

The LCD of denominators 3, 9 and 2 is 72; all three of these divide evenly into 72.  Rewriting the original problem, we get

7 24/72 - 5 64/72 + 8 36/72

Rewriting the original quantities as improper fractions, we get

22/3 - 53/9 + 17/2

Applying the LCD, we get

24(22)       8(53)       17(36)        2764

----------- - ----------- + ---------- = ------------ = 38 7/18

   72             72           72             72

\(7\frac{1}{3}-5\frac{8}{9}+8\frac{1}{2}= \frac{22}{3}-\frac{53}{9} +\frac{17}{2} = \frac{132}{18}-\frac{106}{18}+\frac{153}{18} =\frac{132-106+153}{18} =\frac{179}{18}=9\frac{17}{18}\)

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

For a dilation centered at the origin with a scale factor of 3/2:

(a) original coordinates → final coordinates

R (-4,6) → R' (-6,9)

S (6,2) → S' (9,3)

T (-6,-4) → T' (-9,-6)

(b) (x, y) → ((3/2)x, (3/2)y)

To determine a dilation mapping, follow these steps:

For example, if the center of dilation is (2, 3) and the scale factor is 2, the dilation mapping can be expressed as:

(x, y) → (2(x-2), 3(y-3))

This means that every point (x, y) is transformed into the point (2(x-2), 3(y-3)) after the dilation.
