In total there are 12 marbles because 6+4+2=12 and it says you pick 2 marbles from the hat so you subtract 12-2 and that gives you 10 and it says the marbles aren't returned so therefore you are left with 10 marbles. Hope this helps .

Step-by-step explanation:

Answer:

3/11

Step-by-step explanation

We have 12 marbles in total

First, picking white ones probability is 6/12

Then we set aside the white marble we chose and now we have 11 marbles in total

The number of non-white marbles is 6 and the probability of choosing one of them is 6/11

6/12*6/11 = 3/11

Answer:

please tell me if there iscany sing after 4xy

Answer:

xy-x+y+1

Step-by-step explanation:

(1-x^2)(1-y^2)+4xy=1-y^2-x^2+x^2y^2+4xy

here, 4xy=2xy+2xy

then, -(x^2-2xy+y^2)+(x^2y^2+2xy+1)=-(x-y)^2+(xy+1)^2

by a^2-b^2=(a+b)(a-b)

(xy+1+x-y)(xy+1-x+y)

1-2x+y-x^2y+x^2=-y(x^2-1)+(x^2-2x+1)=-y(x+1)(x-1)+(x-1)^2

=(x-1)(x-1-xy-y)=-(x-1)(xy-x+y+1)

thus, common factor is xy-x+y+1

Answer:

\( P(A) = 0.25, P(B= 0.3\)

And if we want to find \( P(A \cap B)\) we can use this formula from the definition of independent events :

\( P(A \cap B) =P(A) *P(B) = 0.25*0.3= 0.075\)

And the best option would be:

\( P(A \cap B) =0.075\)

Step-by-step explanation:

For this case we have the following events A and B and we also have the probabilities for each one given:

\( P(A) = 0.25, P(B= 0.3\)

And if we want to find \( P(A \cap B)\) we can use this formula from the definition of independent events :

\( P(A \cap B) =P(A) *P(B) = 0.25*0.3= 0.075\)

And the best option would be:

\( P(A \cap B) =0.075\)

Answer:

The answer is D. An Exponential Function.

Step-by-step explanation:

So the table is setup as;

x :   0     1      2     3      4

f(x): 3    7     29    87    199

If you plot the points on the coordinate plane, the value of x increases, and value of y increases .

It is not linear, because slope between two points is not the same, so you can rule that one out.

It´s not quadratic or cubic, because it is not intercepting the x axis.

So, it can only be D, an exponential function since we ruled out every other option.

I hope this helps :))

Answer:

y = 2x -2

Step-by-step explanation:

y = mx + b

We need the slope (m) and the y-intercept (b) to write the eqation.

The slope is the change in y over the change in x.  We can see from the table that the y is changing by 2 as the x changes by 1

So the slope is 2/1 which is the same as 2

The slope (m) is 2.

The y-intercept is the place where the line crosses the y axis.  It is at the point (0,b).  When x is zero, what is y?  If we follow the patter and move to the number before x is 1, we get x = 0.  That means that we have to move back 2 units of the y's.  That would be -2.  So the y-intercept is the point (0,-2).

The y-intercept (b) is -2

y = 2x - 2

Answer:

  9x -4y = -44

Step-by-step explanation:

You want the equation of the line through (-4, 2) and perpendicular to the line through (-4, 6) and (5, 2).

The equation of a line through (h, k) and perpendicular to the line through (x1, y1) and (x2, y2) can be written as ...

  (x2 -x1)(x -h) +(y2 -y1)(y -k) = 0

Using the given points, this becomes ...

  (5 -(-4))(x -(-4)) +(2 -6)(y -2) = 0

  9(x +4) -4(y -2) = 0

Expanding this gives the general form equation:

  9x -4y +44 = 0

Subtracting the constant gives the standard form equation:

  9x -4y = -44

Mrs. Grubbs would get more cookie to eat by choosing the 4 smaller cookies with diameter 5 cm each rather than the single cookie with diameter 14 cm.

To compare the amount of cookie Mrs. Grubbs would get by eating a single cookie with diameter 14 cm and 4 smaller cookies with diameter 5 cm each, we need to consider the total area of the cookies.

The area of a cookie with diameter 14 cm can be calculated as follows:

A = πr^2 = π(7 cm)^2 = 49π cm^2

where r is the radius of the cookie.

On the other hand, the area of a single small cookie can be calculated as follows:

A1 = \(πr^2\) = \(π(2.5 cm)^2\)= \(6.25π cm^2\)

where r is the radius of the small cookie.

Therefore, the total area of 4 small cookies is:

A2 = 4A1 = \(4(6.25π cm^2)\) = \(25π cm^2\)

Comparing the two options, we see that the total area of the 4 small cookies is greater than the area of the single large cookie:

A2 > A

\(25π cm^2 > 49π cm^2\)

It's worth noting that this comparison assumes that the thickness or volume of the cookies is the same for both options. If the cookies have different thicknesses, then the comparison would need to take into account the volume of the cookies instead of just the area.

Answer:

B. Shape A can be matched to shape B by reflecting about the origin and then shifting –3 on the x-axis and 1 on the y-axis.

Step-by-step explanation:

Answer: Choice A

Note: the range should be \([-5, \infty)\). See explanation below.

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

We can plug in any real number for x to get some output for y. The domain is the set of all real numbers in which we say \((-\infty, \infty)\) which is interval notation. It represents the interval from negative infinity to positive infinity.

The range is the set of possible outputs. The smallest output possible is y = -5 which occurs at the vertex (3,-5). We can get this y value or larger. So we can describe the range as the set of y values such that \(y \ge -5\) and that translates to the interval notation \([-5, \infty)\).

The square bracket says "include this endpoint" while the curved parenthesis says to exclude the endpoint. Your teacher mistakenly wrote \((-5, \infty)\) for choice A, when they should have written \([-5, \infty)\)

I think either your teacher made a typo or somehow the formatting messed up. Either way, choice A is the closest to the answer.

Option A is the correct choice .

Domain will be → all real numbers .

Range will be → y belongs to R : y greater than or equal to -5 .

→ (x+3)^2 It means 0 to infinity

So (x+3)^2-5= (-5, infinity)

→ Range = (-5, infinity )

(3, -1)

Any point can be located using a Cartesian coordinate system or coordinate system, and that point can be displayed as an ordered pair (x, y) known as Coordinates. The origin, denoted by the letter "O," is the point where the two number lines intersect. The horizontal number line is known as the X-axis, and the vertical number line is known as the Y-axis.

Reflection of a coordinate in x-axis, negates the y - coordinate.

So, negation of 1 = -1

Answer:

x^2 + y^2 = r^2

Step-by-step explanation:

See image. "An angle in standard position" means the vertex (point part) of the angle is at the origin (0,0). And one side of the angle is glued onto the x-axis. The other side of the angle is free to rotate around the axis. That's the terminal side. Then there's a point P (x,y) on that side. See image. And r is labelled there. This set up makes a right triangle. So I put Pythagorean theorem as the answer here, but honestly if you are learning any right triangle theorems or trigonometry, you could use this set up. The leg that lays along the x-axis is x units long and the other leg is y units long. The hypotenuse is r units long.

Given:

To find the inverse of f(x), we first switch x and y and then solve for y. So, x = y-3/y+4, which we can rewrite as x(y+4) = y-3. Simplifying, we get xy + 4x = y-3, and then we can isolate y on one side: y-xy = 4x-3. Factoring out y on the left side, we get y(1-x) = 4x-3, and then we can divide both sides by (1-x) to get y = (4x-3)/(1-x). This is our inverse function.

Find:

To find the inverse of g(x), we follow the same process of switching x and y and solving for y. So, x = 4y+3/1-y, which we can rewrite as x(1-y) = 4y+3. Simplifying, we get -xy + y = 4x+3, and then we can isolate y on one side: y(-x+1) = 4x+3. Dividing both sides by (-x+1), we get y = (4x+3)/(-x+1). This is our inverse function.

Solve:

As for the given set of values, we have 187, 191, 202, 209, 218, and 1984. The outlier is obviously 1984, and its presence will not affect the range because the range is simply the difference between the largest and smallest values, which will be the same regardless of the presence of an outlier. However, the outlier will greatly affect the interquartile range, which is the difference between the upper and lower quartiles. This is because the upper and lower quartiles are the median of the upper half and lower half of the data, respectively, and including an outlier in one of these halves can greatly skew the median and thus the interquartile range.
