Can you divide 2 by 9? Explain your response.

Answers

Answer 1

Answer:

0.22222222222

Step-by-step explanation:

To divide two by nine, you need to use your long division skills. Unfortunately, this interface doesn't lend itself well to showing you the actual long division problem, so try to follow the steps with me.

draw a division symbol (should look like half a rectangle). Put the 9 in front of the rectangle and a 2 inside it. Make the top of the rectangle long.

Note that the result of the division 2÷9 is not an exact value and is equivalent to recurring decimal 0.22... (which has 2 as the period).

Find the discriminant of the quadratic equation x2 14x 8 = 0 and use it to determine the number and types of solutions. b2 − 4ac

Answers

The discriminant is 164 and there are two real solutions.

What is Quadratic equation?

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax^2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.

We can find the discriminant as shown below:

x^2+14x+8=0

a=1, b=14, c=8

Discriminant=b^2-4ac

=(14)^2-4*1*8

=196-32

=164>0

As the discriminant is positive and greater than zero. So, there are two real and distinct solution.

Hence, discriminant is 164 and two real solution.

Determine the equation of the circle with centre (-3;5) and passing through a point (2;-9)

Answers

Therefore, the equation of circle is: [tex](x+3)^{2}+(y+5)^{2} = 100[/tex]

What is a circle?All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant. The radius of a circle is the separation between any point on the circle and its center. The radius must typically be a positive integer. Except when otherwise specified, this article discusses circles in Euclidean geometry, namely the Euclidean plane. A circle, specifically, is a straightforward closed curve that separates the plane into its inner and exterior.

Here we know that[tex](h,k) = (-3,5)[/tex]but we are not given the radius.

However, we can find the radius by using the distance formula.

[tex]\sqrt{x^{2} +y^{2} }[/tex], where [tex]x=x_{1} -x_{2}[/tex] and [tex]y=y_{1} -y_{2}[/tex]

Putting the values, we get:

[tex]\sqrt{8^{2} +6^{2} }[/tex]

The radius comes out to be:

[tex]r=10[/tex]

An equation of the circle with center [tex](h,k)[/tex] and radius r is

[tex](x-h)^{2} +(y-k)^{2} = r^{2}[/tex]

Now, substituting the values, we get:

[tex](x--3)^{2} +(y-5)^{2} = 10^{2}[/tex]

Therefore, the equation of circle is:

[tex](x+3)^{2}+(y+5)^{2} = 100[/tex]

See attachment for graph

Type of correlation

The correlation is a negative correlation, because weights and city MPG do not increase at the same time

The equation of the line of best fit

To do this, we make use of a graphing calculator.

From the graphing calculator, we have the following summary:

Sum of X = 463Sum of Y = 388Mean X = 28.9375Mean Y = 24.25Sum of squares (SSX) = 862.9375Sum of products (SP) = -857.75

The line of best fit equation is

y = bx + a

Where

b = SP/SSX = -857.75/862.94 = -0.99

a = MY - bMX = 24.25 - (-0.99*28.94) = 53.0

So, we have:

y = -0.99x + 53

Hence, the equation of the line of best fit is y = -0.99x + 53

The weight for 30 MPG

This means that y = 30

So, we have:

-0.99x + 53 = 30

Subtract 53 from both sides

-0.99x = -23

Divide by -0.99

x =23

Hence, the predicted weight is 23 pounds

The city MPG for 1500 pounds

This means that x = 1500

So, we have:

y = -0.99 * 1500 + 53

Evaluate

y = -1432

Hence, the city MPG for 1500 pounds is -1432

The gas exerts a pressure of 218.75 kPa when its volume is reduced to 2.0 L, following the behavior of an ideal gas.

Ideal gas behavior:

Suppose the initial volume of carbon dioxide gas is V = 3.5l

Since the volume is reduced to 2.0l, the final volume is shown as V'= Will be done. 2L

The final pressure of the gas is P'.

We consider the behavior of gas to be ideal. From the ideal gas equation, it becomes as follows.

The force will be calculated. We can make an equation from the given data in the question:-

[F1/F2] = [d2/d1]

F2 = [F1 x d1 ] / [d2]

F2 = [ 80 x 9 ] / [ 15 ]

I need help writing a 2 column proof

Answers

The proof that quadrilateral WXYZ, having vertices W(-5, 6), X(-1, 10), Y(1, 4), and Z(-2, -3) is a trapezoid is given below.

What is a mathematical proof?

Mathematical proof is a set of logical statements that are sequentially indicated to guaranty that a stated position is indeed accurate.

What is the proof for the quadrilateral above?

It is to be noted that with parallelograms, the diagonals intersect at the midpoints. (See the attached image).

The Diagonals are  WY  and  XZ; Where

WY :  (-4, -3) to  (6, -2); and

Midpoint is  [ (0 + 2)/2 ,  (-1 + -4)/2 ]  

= (1, -5/2)

The diagonals are bisectors of each other.

It is to be noted that the diagonals are not congruent. For if they were congruent, then the above would not be a trapezoid.

The Length of WY  = √((-4 - 6)²  +  (-3 - (-2))²)

WY = √(100 + 1)

WY = √101

The Length of XZ =    √((0 - 2)²  +  ( -1 - -4)²)

XZ = √(4+9)

XZ = √13

From the above, it is clear that both diagonals are unequal. Hence, given the first and second proof, we can state that quadrilateral WXYZ is a Trapezoid.

Which statement correctly compares the mean number of students for the data in the plots?

Answers

The correct answer is option B: there are about 2 more students in each class at Oak Middle School than at Poplar Middle School.

What are statistics?

The practice or science of organizing and interpreting numerical data in big quantities, particularly for the objective of concluding proportions in a whole from those in an expected sample.

From the dot plot attached, we can find the average number of students per class for each school.

For Poplar Middle School;

Total number of students = (20 × 3) + (21 × 5) + (22 × 7) + (23 × 4) + (24 × 1) = 435 students.

There are 20 classes.

Thus;

Average number of students per class = 435/20 = 21.75

For Oak Middle School;

Total number of students = (20 × 1) + (21 × 2) + (22 × 2) + (23 × 4) + (24 × 3) + (25 × 2) + (26 × 2) + (27 × 2) + (28 × 1) + (29 × 1) = 483

The average number of students per class; 483/20 = 24.15

Difference in average = 24.15 - 21.75 = 2.40

This implies that there are about 2 more students in each class at Oak Middle School than at Poplar Middle School.

Therefore the correct answer is option B: there are about 2 more students in each class at Oak Middle School than at Poplar Middle School.
