Answer:

Yes

Step-by-step explanation:

You can use the perpendicular bisector theorem, because the bisecting line is intersecting at a right angle, which means it is actually perpendicular. Along with IJ and IH being congruent (equal)

Choose Yes or No to tell whether each expression is equivalent to –43p – 25.
Rashid [163]

Answer:

–43p + (–25)  is  EQUIVALENT to  –43p – 25.

Step-by-step explanation:

<u>The options are MISSING.</u>

The needed options are:

1. 25 – 43p

2. 25 – 43p

3. –25p –43

4. –43p + (–25)

Now, here the given expression is:  –43p – 25

Taking each option and simplifying it , we get:

1. 25 – 43p

Here, the second term is NEGATIVE, but the first term (25) is POSITIVE.

⇒  25 – 43p  ≠ –43p – 25

Hence, 25 – 43p is  NOT EQUIVALENT.

2. 25 – 43p

Here, the second term is NEGATIVE, but the first term (25) is POSITIVE.

⇒  25 – 43p  ≠ –43p – 25

Hence, 25 – 43p is  NOT EQUIVALENT.

3. –25p –43

Here, the variable p is multiplied with (-25) and NOT (-43).

⇒   –25p –43 ≠ –43p – 25

Hence,  –25p –43 is  NOT EQUIVALENT.

4. –43p + (–25)

Here, both the given terms (43) and (25) are NEGATIVE.

Also, the varibale p is multiplied with (-43)

⇒  –43p + (–25) = –43p – 25

Hence, –43p + (–25)  is  EQUIVALENT.

4x - y = 3<br> The coordinate points for that equation
zlopas [31]

Answer:

Step-by-step explanation:

4x - y = 3

add Y to both sides

4x = 3 + y

minus 3 from both sides

y = 4x - 3

Instructions:Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.
Svetllana [295]

Answer:

D = 108°

F = 180°

H = 252°

I = 288°


Explanation:

Every regular polygon with <em>n </em>sides can be divided into <em>n</em>  congruent triangles. The angle with vertex the center of the polygon will measure 360 : <em>n </em>degrees. This will also be the angle of rotation under which the polygon matches itself.

We are given a regular decagon, therefore:

<em>n </em>= 10

α = 360 : <em>n </em>= 36°


We consider that, if the decagon is not rotated, A' coincides with A and the rotation is towards the next letter of the alphabet. This means that after one rotation of 36° A' will coincide with B, after two rotations A' will coincide with C and so on.

A' will coincide with D after three rotations: 3 × 36° = 108°

A' will coincide with F after five rotations: 5 × 36° = 180°

A' will coincide with H after seven rotations: 7 × 36° = 252°

A' will coincide with I after eight  rotations: 8 × 36° = 288°

A random variable X has a Poisson distribution with a mean of 3. What is the probability that X P(1≤X≤3) ?.
frosja888 [35]

Answer:

P(1≤X≤3) = 0.5974

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given interval.

Mean of 3

This means that \mu = 3

P(1≤X≤3) ?

P(1 \leq X \leq 3) = P(X = 1) + P(X = 2) + P(X = 3)

So

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

P(X = 1) = \frac{e^{-3}*3^{1}}{(1)!} = 0.1494

P(X = 2) = \frac{e^{-3}*3^{2}}{(2)!} = 0.2240

P(X = 3) = \frac{e^{-3}*3^{3}}{(3)!} = 0.2240

So

P(1 \leq X \leq 3) = P(X = 1) + P(X = 2) + P(X = 3) = 0.1494 + 0.2240 + 0.2240 = 0.5974
