Answer:

(6, 0)

Step-by-step explanation:

Coordinates are written in the form (x, y), where x is the x-axis value that the point is in, in this case 6, and where y is the y-axis value, in this case 0.

Hi!

Answer:

(6, 0)

Step-by-step explanation:

Coordinate point "G" on this graph is on the very bottom. On the X axis, point G is on the 6. On the Y axis, its on the 0, so since the domain, (X) comes first before the range, (Y), you get (6, 0)

Answer:

Step-by-step explanation:

Quadratic equation has a leading degrees of 2. The correct equation in vertex form is (x - 3)^2 + 5

Quadratic equation has a leading degrees of 2.

Given the quadratic function expressed as:

f(x) = x^2 - 6x + 14

Complete the square

x^2 - 6x + (-3)^2 - (-3)^2 + 14

(x- 3)^2 - 9 + 14
(x - 3)^2 + 5

Hence the correct equation in vertex form is (x - 3)^2 + 5

Angle one and two lie on straight line.

this means there sum is equal to 180°

Given :-

so we can say :-

[tex] \angle1 + \angle2 = 180 \degree \\ 7x + x + 12 = 180 \\ 8x + 12 = 180 \\ 8x = 180 - 12 \\ 8x = 168 \\ x = \frac{ \cancel{168} {}^{ \: \: 21} }{ \cancel8} \\ x = 21 \degree[/tex]

so angle one = 7x= 7×21 = 147°

angle two = x+12 = 21+12 = 33°

Answer:

y = 15

Step-by-step explanation:

JKLM ~ PQRS means that quadrilateral JKLM is similar to quadrilateral PQRS.

In similar shapes the corresponding sides have same ratio and the corresponding angles are congruent.

This means angle J is congruent to angle P, K is congruent to Q, L is congruent to R and M is congruent to S. Order of the vertices matters.

Solving for y.

Angle J is congruent to angle P.

5y - 4 = 71 Add 4 on both sides.

5y = 71 + 4

5y = 75  Divide both sides with 5.

y = 15

(Btw your solution for x is wrong.)

For the spinner with 3 sectors, the total number of outcomes for 3 spins is 27.

A combination is a mathematical technique that determines the number of possible arrangements.

Let's we have to define

A, B, and C, as the regions in the spinner.

So, we spin it 3 times, and for each of these times there are 3 outcomes, so the outcomes will be of the form:

The outcome of spin 1, the outcome of spin 2, outcome of spin 3.

The total number of  different outcomes will be:

3^3 = 27

Step-by-step explanation:

A) as you can see there is no current flowing in a bar magnet so (incorrect)

B) Lines of magnetic field is going in A-->B direction so it have starting and ending points.(incorrect)

C) Yes whenever a magnetic object is placed near the another magnetic object they either attract or repell so they have a force in a form of push and pull [correct]

D)No because magnetic field lines goes from North--> South so A is the South pole [ incorrect]

E) Yes it will point always towards North pole of the magnet [correct]

F) yes it depends upon the density of field lines[correct]

G)No the near the magnet is it becomes more stronger as compared to magnet kept far.(incorrect)

So option C E F are correct

===========================================================

Explanation:

There are two approaches here.

Method 1

Focus on the numbers along the top only.

The left arrow points at 50 while the arrow on the right points at 180. Subtract these numbers to get 180 - 50 = 130

------------------------------

Method 2

Focus on the numbers along the bottom row this time.

The left arrow points at 130 and the right arrow points at 0

The difference of which is 130 - 0 = 130

Because we're subtracting off 0, it means we can simply look at only one number without having to do any math. This only works if the other portion of the angle is pointing at 0 or 180.

------------------------------

Notice that 130 degrees is larger than 90, so this angle is obtuse. This means that if you aren't sure whether to go with 50 or 130, it will depend on if it's acute or obtuse.

Answer:

x = 59

Step-by-step explanation:

[tex]\frac{1}{4}[/tex] x = 14 [tex]\frac{3}{4}[/tex] ← convert to improper fraction

[tex]\frac{1}{4}[/tex] x = [tex]\frac{59}{4}[/tex] ( multiply both sides by 4 to clear the fractions )

x = 59

Answer:

8%

Step-by-step explanation:

9+3=12 (total number of students that write left handed)

12/150 x 100% = 8%

The probability of rolling the die once to get a four is 1/6

So we do 1/6*1/6*1/6 which is 1/216 since it's combined probabilities

Answer:

26.17%

Step-by-step explanation:

P(Grey) = 1/4

P(Grey at least 2 times in 4) = 1 - P(no Grey in 4) - P(1 Grey in 4)

P(no Grey in 4) = 4C0 * 3/4 * 3/4 * 3/4 * 3/4 = 81/256

P(1 Grey in 4) = 4C1 * 1/4 * 3/4 * 3/4 * 3/4 = 27/64

P(Grey at least 2 times in 4) = 1 -  81/256 -  27/64 = (256-81-108)/256=67/256=26.17%

Answer:

44 degrees

Step-by-step explanation:

angle c = 90 degrees

angle a = 46 degrees

the measure of all sides on a triangle is 180

so to solve for the other side we can do this equation...

180 - (90 + 46) = 44

The best answer from the options that proves that the residual plot shows that the line of best fit is appropriate for the data is: ( Statement 1 ) Yes, because the points have no clear pattern

X         Given     Predicted     Residual value

1            3.5           4.06             -0.56

2           2.3           2.09             0.21

3            1.1            0.12               0.98

4           2.2           -1.85              4.05

5          -4.1            -3.82            -0.28

The residual value is calculated as follows using this formula: ( Given - predicted )

1) ( 3.5 - 4.06 ) = -0.56

2) ( 2.3 - 2.09 ) = 0.21

3) ( 1.1 - 0.12 ) = 0.98

4) (2.2 - (-1.85) = 4.05

5) ( -4.1 - (-3.82) = -0.28

Residual values are the difference between the given values and the predicted values in a given data set and the residual plot is used to represent these values .

attached below is the residual plot of the data set
