Given: m ∠XOY = m ∠WOV
m YZ = m ZW
Prove: m XZ = m ZV

Complete The Following Proof.Given: M XOY = M WOVm YZ = M ZWProve: M XZ = M ZV

Answers

Answer 1

Answer:

Step-by-step explanation:

m ∠XOY = m ∠WOV

so, m XY = m WV --- (i)

     { If angle subtended by two arcs at the center are equal, then length of arc are equal}

m YZ = m ZW  ------- (ii)    {given}

Add (i) and (ii)

XY + YZ = WV + ZW

XZ = ZV    

Hence proved.

Answer 2

Answer:

Given that m ∠XOY = m ∠WOV then m XY = m WV, because central angles are equal to arcs.

Given: m YZ = m ZW

The addition of arcs XY and YZ make arc XZ, that is: m XY + m YZ = m XZ

The addition of arcs ZW and WV make arc XZ, that is: m WV + m ZW = m ZV

Then, m XZ = m ZV

Jane has rolled a fair die 7 times and each time has gotten a 3. She says that the probability that she will get a 3 on the next roll is high (close to 1). Is she correct?
A) No, the probability of getting a 3 on a fair die does not change. It will always be 1/6
no matter what she got on the previous roll.
B) Yes, since she has gotten a 3 on the last 7 rolls, the probability of getting a 3 is higher on the next roll.
C) No, the probability of getting a 3 will be slightly higher than any other number but not close to 1.
D) There is no way to tell until she rolls the die. You cannot accurately predict what she will get.

Answers

A) No, the probability of getting a 3 on a fair die does not change. It will always be 1/6  no matter what she got on the previous roll.

Step-by-step explanation:

Lets define probability first

"Probability is the likeliness of occurrence of an event"

When we call a die fair, that means that each number on the die has an equal chance of occurrence when rolled.

If on 7 rolls, the outcomes were 7 each time, this doesn't mean that the chances of rolling a specific number on a fair die is changed. On the next roll, 3 will have the same probability as before that is 1/6

So,

The correct answer is:

A) No, the probability of getting a 3 on a fair die does not change. It will always be 1/6  no matter what she got on the previous roll.

What is the point slope equation of line that passes through the point (2,-3) and has the same y intercept as y =5×+2

Answers

Answer:

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

Step-by-step explanation:

First look at y =5x + 2.  It's immediately apparent that the y-intercept is 2, or (0, 2).  (0, 2) must then be a point on the new line, and we are told that (2, -3) is also on this new line.

The general point-slope equation is y - k = m(x - h).

We need to determine the slope of the new line.

Let h = 2, k = -3, x = 0 and y = 2.  Then:

2 + 3 = m(0 - 2).  Therefore, -2m = 5, and m = -5/2.

Then the equation of the new line, in point-slope form, is

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

Let's check this result.  Do the coordinates of the y-intercept, (0, 2) satisfy this equation?

Is 2 + 3 = (-5/2)(0 - 2) true?

Is 5       = (-5/2)(-2) true?  YES

The equation of line is 2y = -5x+ 4.

What is slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. The slope of the line is the ratio of the rise to the run, or the rise divided by the run, therefore the change in y coordinate with regard to the change in x coordinate may be expressed as follows

m = Δy/Δx

where, m is the slope

In the coordinate plane, it describes the slope of the line.

Given:

passes through the point (2,-3) and has the same y intercept as y =5×+2

The, the intercept for the required line is 2.

Now, using y= mx+b

-3 = m(2) + 2

2m = -5

m= -5/2

Now, the equation of line passes through (2, -3)

y - y1 = m(x- x1)

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

2y + 6= -5x+ 10

2y = -5x+ 4

Hence, the equation of line is 2y = -5x+ 4.

Answers

Answer:

y = 5x - 10 and y = 5(x + 2) are the system of equations that has no solution.

Step-by-step explanation:

The slope-intercept form of a straight line equation is given by, y = mx + c, where m is the slope and c is the y-intercept.

Now, only a system of parallel straight lines has no solution.

And the parallel straight lines have an equal slope and different y-intercept.

Hence, the given equation, y = 5x - 10 has slope equals to 5 and y-intercept - 10.

And the lines given in the options, only the second line i.e. y = 5(x + 2) has the same slope i.e. 5 and different y-intercept i.e. 10 ≠ - 10.

So, y = 5x - 10 and y = 5(x + 2) are the system of equations that has no solution. (Answer)

Given a grid with 15 sections, determine how many sections in the grid need to be shaded so the probability of a point chosen at random in the shaded area is exactly 0.8. Explain your reasoning

Answers

0.8 is equal to 80%

you need to figure out 80% of 15

100% = 15

10% = 1.5

(x8)

80% = 12

you would need to shade 12 out of 15 boxes which gives 0.8 chance of picking a shaded one

Answer:

Sample answer: The number of squares that are shaded divided by 15 must equal 0.8, so the number of squares must be 0.8(15), which equals 12. The fraction 12/15 reduces to 4/5 which is equal to 8/10.

apply the distributive property to Factor out the greatest common factor of 75+20​

Answers

Final answer:

The greatest common factor of 75 and 20 is 5, and by applying the distributive property, the expression 75+20 can be factored as 5(19).

Explanation:

The greatest common factor (GCD) of 75 and 20 is 5. Applying the distributive property to factor out 5, we get:

75 + 20 = 5 × (15 + 4)

Here's the breakdown:

Find the GCD: The largest factor that divides both 75 and 20 is 5.

Divide each term by the GCD: Divide 75 by 5 to get 15 and divide 20 by 5 to get 4.

Rewrite with the GCD factored out: Combine the results from step 2 and multiply by the GCD: 5 × (15 + 4).

Therefore, the factored expression using the distributive property is 5 × (15 + 4).

Thus, the factored form of the expression 75+20 is 5(19).

x - 3(2x - 7) = 76
Help!

Answers

Answer:

To solve this equation your goal is to get x by itself

First we need to distribute the 3 through the (2x-7)

x-6x+21=76 (-3*2x=-6x, -7*-3=21)

Your next step is to combine like terms

-5x+21=76 (x-6x=-5x)

Next subtract 21 from both sides

-5x=55 (21-21=0, 76-21=55)

Last you need to divide both sides by -5

x=-11 (-5/-5=1, 55/-5=-11)

x=-11

Hope this helps ;)

The solution to the given equation x - 3(2x - 7) = 76 is x = -11.

The equation is given as follows:

x - 3(2x - 7) = 76

First, distribute the 3 to the terms inside the parentheses:

x - 6x + 21 = 76

Combine like terms:

-5x + 21 = 76

Subtract 21 from both sides:

-5x = 76 - 21

-5x = 55

Divide both sides by -5 to solve for x:

x = 55 / -5

x = -11

Therefore, the solution to the given equation x - 3(2x - 7) = 76 is x = -11.
