Transforming the points involves changing their coordinates

The image of the points are: (3, 6), (-11, 12) and (-3, -12)

<h3>How to complete the transformations?</h3>

The coordinates of the points are given as:

X(2, 4)

Y(5,-3)

Z(-7, 1)

<u>a) Rotate the points 90 degrees clockwise</u>

The rule of this transformation is:

(x, y) to (y, -x)

So, we have:

X' = (4, -2)

Y' = (-3, -5)

Z' = (1, 7)

<u>b) Dilation by a scaling factor of 2</u>

The rule of this transformation is:

(x, y) to (2x, 2y)

So, we have:

X'' = (8, -4)

Y'' = (-6, -10)

Z'' = (2, 14)

<u>c) Reflect across the x-axis</u>

The rule of this transformation is:

(x, y) to (x, -y)

So, we have:

X''' = (8, 4)

Y''' = (-6, 10)

Z''' = (2, -14)

<u>d) Translation 2 Up and 5 to the Left</u>

The rule of this transformation is:

(x, y) to (x -5, y + 2)

So, we have:

X'''' = (3, 6)

Y'''' = (-11, 12)

Z'''' = (-3, -12)

Hence, the image of the points are: (3, 6), (-11, 12) and (-3, -12)

Marianna [84]

Answer:

32.33% probability of having at least 3 erros in an hour.

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 time interval.

The mean number of errors is 2 per hour.

This means that $\mu = 2$

(a) What is the probability of having at least 3 errors in an hour?

Either you have 2 or less errors in an hour, or we have at least 3 errors. The sum of the probabilities of these events is decimal 1. So

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

We want $P(X \geq 3)$

$P(X \geq 3) = 1 - P(X \leq 2)$

In which

$P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)$

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

$P(X = 0) = \frac{e^{-2}*(2)^{0}}{(0)!} = 0.1353$

$P(X = 1) = \frac{e^{-2}*(2)^{1}}{(1)!} = 0.2707$

$P(X = 2) = \frac{e^{-2}*(2)^{2}}{(2)!} = 0.2707$

$P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.1353 + 0.2707 + 0.2707 = 0.6767$

$P(X \geq 3) = 1 - P(X \leq 2) = 1 - 0.6767 = 0.3233$

32.33% probability of having at least 3 erros in an hour.

Nina [5.8K]

Answer: 4 years after the original investment, it is approximately $1,093.

Step-by-step explanation:

Hi, to answer this question we have to apply the simple interest formula:

I = p x r x t

Where:

I = interest

P = Principal Amount

r = Interest Rate (decimal form)

t= years

Replacing with the values given

I = 1000x (2.25/100) x t

It will triple in approximately 3 years. FALSE

I = 1000x (2.25/100) x 3 =67.5

1000+67.5 = 1067.5

It will no longer grow after several years: False, it will grow because it has a growth rate.

4 years after the original investment, it is approximately $1,093. TRUE

I = 1000x (2.25/100) x 4 =90

1000+90 = $1090

It will double in approximately 10 years.

I = 1000x (2.25/100) x 10 =225

1000+90 = $1225
