X-int =(-3,0)
Y-int=(0,_1)
Slope: _1/3

As for the slope, it is the deviation of the line from a horizontal. Slope is expressed as $\frac{change in y}/{change in x}$ .
A point is any point on the coordinate plane. Points are expressed as an ordered pair in the form (x,y). Examples include (5,) and (2,1).
The x-intercept of a line is the point at which it intercepts, or intersects, the x-axis. In other words, it is the point where the line crosses the x-axis.
The y-intercept of a line is the point where it intercepts the y-axis.

Tiffany sees this given dilation and claims that the scale factor is 2

Alenkinab [10]

Answer:

The scale factor is not 2

Step-by-step explanation:

Given

See attachment for the dilated triangles

Triangle ABC is dilated through center point O to form triangle A'B'C'.

From the attachment, we have:

$OC = 2$ i.e. the distance from the center point to C

and

$OC' = 6$ i.e. the distance from the center point to C'

The length of OC' is calculated using:

$OC' = OC + CC'$

$OC' = 2 + 4$

$OC' = 6$

The scale factor (k) is then calculated by dividing OC' by OC

$k = \frac{OC'}{OC}$

$k = \frac{6}{2}$

$k = 3$

Hence, Tiffany's claim is incorrect.

Consider the following data: x −4−4 −3−3 −2−2 −1−1 00 P(X=x)P(X=x) 0.20.2 0.30.3 0.10.1 0.20.2 0.20.2 Copy Data Step 4 of 5 : Fi

AysviL [449]

Answer:

$P(x\geq -1) = 0.4$

Step-by-step explanation:

We are given the following in the question:

x: −4 −3 −2 −1 0

P(X=x): 0.2 0.3 0.1 0.2 0.2

We have to evaluate

$P(x\geq -1)$

Since it is a discrete probability distribution as

$\displaystyle\sum P(X=x_i) = 0.2 + 0.3 + 0.1 + 0.2 + 0.2 = 1$

We can evaluate the probability as:

$P(x\geq -1) = P(x = -1 + P(x = 0)\\P(x\geq -1) = 0.2 + 0.2\\P(x\geq -1) = 0.4$

Thus, 0.4 is the require probability.

multiplication is defined as repeated addition.use the word repeated to define exponential form.justify your reasoning.

mash [69]

Exponential form is when a certain number is raised to the power of a certain number or also known as exponents. Exponents signifies that the base or the number that is being raised to a certain powers will be multiplied a number of times, based on the exponents).

Exponential form is defined as repeated multiplication of the base.
