Answer: -4 over 0 (I think) I hope this helps a little bit

Step-by-step explanation: Finding the slope

(-14,-10) and (-14,-6)

Use your Y values and subtract them -10-(-6) or -10 + 6= -4 that will be your numerator

Use your 2 X values and subtract them -14-(-14) or -14+14=0  that will be your denominator

Slope will be  -4 over 0

Step-by-step explanation:

The perimeter of triangle VYZ is 12 units.

The perimeter of a triangle is the sum of the whole sides of the triangle.

In other words, the perimeter of a triangle is the total distance covered by its boundaries or the sides.

Therefore,

perimeter of ΔVYZ = VY + ZY + ZV

Therefore,

VY  =  ZY = ZV = XW

Hence,

YW = YX + XW

Therefore,

XW = YW - YX

YW  = 3x - 1

YX = 1

Hence,

XW = 3x - 1 - 1

XW = 3x - 2

Therefore,

perimeter of ΔVYZ = 3x - 2 + 3x - 2 + 3x - 2

perimeter of ΔVYZ = 9x - 6

ZX = YW

2x + 1 = 3x - 1

2x - 3x = - 1 - 1

-x = -2

x = 2

Therefore,

perimeter of ΔVYZ = 9(2) - 6

perimeter of ΔVYZ = 18 - 6

perimeter of ΔVYZ = 12 units

The value of variable x and y are 24 and 19 respectively.

We have to find the variables x and y of the angles.

Therefore,

using angles in a triangle,

2x + 13 + 47 + 5y - 23 = 180

2x + 5y = 180 - 13 - 47 + 23

2x + 5y = 143

Using corresponding angles,

180 - (2x + 13) = 47 + 3x

180 - 2x  - 13 = 47 + 3x

180 - 47 - 13 = 3x + 2x

120 = 5x

x = 120 / 5

x = 24

Hence,

2(24) + 5y = 143

5y = 143 - 48

5y = 95

y = 95 / 5

y = 19

To find the scale factor of the model to the sculpture, we have to divide one set of measurements of the model and sculpture.

Let us divide the length of the model by that of the sculpture:

That is the scale factor of the model to the real sculpture.

A34 should represent either a square matrix with number of columns=number of rows =34 or the 4th element in the 3rd row in the matrix A [which is not possible in the given matrix since each row has only 3 elements]

The dimension of a matrix is given as (the number of rows it has, say a) x (the number of columns it has, say b) [read as a by b].. The given matrix has 4 rows and 3 columns, so its dimension is 4x3.

For a matrix A of dimension axb to be multiplied with a matrix B of dimension cxd, the number of columns of matrix A should be equal to the number of rows of matrix B, that is b = c should be satisfied. In this case both matrices are of the same dimension 2x3 but 3 (number of columns in first matrix) is not equal to 2 (number of rows in second matirx). So these matrices cannot be multiplied as their dimensions do not match.

A confidence interval is made up of the mean of your estimate plus and minus the estimate's range. This is the range of values you expect your estimate to fall within if you repeat the test, within a given level of confidence.

A 95% confidence interval gives you a 5% chance of being wrong. A 90% confidence interval gives you a 10% chance of being wrong. In comparison to a 99% confidence interval, a 95% confidence interval is smaller (for example, plus or minus 4.5 percent instead of 3.5 percent).

When constructing a confidence interval for a propotion, if the condition of proportion requires 10 individuals in each category is not met, then confidence interval should be adjusted.

The number of individuals in each category is increased by 2 and sample size increases by 4.

Step-by-step explanation:

you can check the the correct answer by giving tables value for eg f(x)= 2 g(f(x))= 1/2(2)²=2

The table will be:

Number of Minutes: 0.25. 0.5. 0.75 1

Number of heartbeats: 0.6675 1.335 2 2.67

The veterinarian recorded a cat's resting heart rate to be 120 beats over a 45-second time period. The constant will be:

= 120 / 45

= 2.67

Therefore, to find the heartbeat, we have to multiply the numbers of minutes by 2.67. This is illustrated as:

= 2.67 × 0.25 = 0.6675

Pythagoras theorem states that the square of hypotenuse equals the sum of square of other two sides.

now using quadratic formula ,

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

Work Shown:

As you mentioned, we'll use Pythagoras' Theorem aka Pythagorean Theorem.

[tex]a^2+b^2 = c^2\\\\(x+3)^2+(4(x+2))^2 = 25^2\\\\(x+3)^2+16(x+2)^2 = 625\\\\(x^2+6x+9)+16(x^2+4x+4) = 625\\\\x^2+6x+9+16x^2+64x+64 = 625\\\\17x^2+70x+73 = 625\\\\17x^2+70x+73-625 = 0\\\\17x^2+70x-552 = 0\\\\[/tex]

Next, we'll use the quadratic formula with a = 17, b = 70, c = -552.

[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-70\pm\sqrt{(70)^2-4(17)(-552)}}{2(17)}\\\\x = \frac{-70\pm\sqrt{42436}}{34}\\\\x = \frac{-70\pm206}{34}\\\\x = \frac{-70+206}{34} \ \text{ or } \ x = \frac{-70-206}{34}\\\\x = \frac{136}{34} \ \text{ or } \ x = \frac{-276}{34}\\\\x = 4 \ \text{ or } \ x \approx -8.1176\\\\[/tex]

Ignore the negative x value solution. The sides (x+3) and 4(x+2) will be negative values if we plugged in x = -8.1176, but negative side lengths do not make sense.

This makes x = 4 the only possible solution.
