Answer:

C counterclockwise 90 rotation; enlargement

Step-by-step explanation:

From the photo, we can see that triangle A"B"C" is the product of triangle ABC  after the transformation.

Please have a look at point C on line y-axis and after that it lies on x-axis. So we have possible reasons:

1. rotated either counterclockwise 90°

2. rotated clockwise 270°.

The rule is: (x,y)\rightarrow (-y,x)

The corresponding sides of image A"B"C" are bigger than the preimage ABC.  

k=\frac{A"B"}{AB}=\frac{6}{2}=3 > 0

Because k >0, the transformation shows the enlargement

So we choose option C counterclockwise 90 rotation; enlargement

Answer:

The measure of \angle 3 :

\angle 3 = 45\textdegree

Step-by-step explanation:

The measurement of \angle 3 is also 45\textdegree, because both \angle 3 and the angle with the measure of 45\textdegree are congruent.

Please Help me Please Please the question and options are in the picture
Vladimir [108]

The correct answer is B)x = \frac{y - p + mq}{m}.

In order to find this, we need for follow the order of operations.

y - p = m(x - q) ----> Divide both sides by m

\frac{y - p}{m} = x - q ----> add q to both sides

\frac{y - p}{m} + q = x ---> now we need to give it a common denominator. Multiply the q term by m/m

\frac{y - p + mq}{m} = x

This is our final answer.

It appears that people who are mildly obese are less active than leaner people. One study looked at the average number of minute
hoa [83]

Answer:

Obese people

Lower = \mu - 2\sigma = 373- 2(67) = 239

Upper = \mu + 2\sigma = 373+ 2(67) = 507

Lean People

Lower = \mu - 2\sigma = 526- 2(107) = 312

Upper = \mu + 2\sigma = 526+ 2(107) = 740

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

The empirical rule, also referred to as the three-sigma rule or 68-95-99.7 rule, is a statistical rule which states that for a normal distribution, "almost all data falls within three standard deviations (denoted by σ) of the mean (denoted by µ). Broken down, the empirical rule shows that 68% falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ)".

Solution to the problem

Obese people

Let X the random variable that represent the minutes of a population (obese people), and for this case we know the distribution for X is given by:

X \sim N(373,67)  

Where \mu=373 and \sigma=67

On this case we know that 95% of the data values are within two deviation from the mean using the 68-95-99.7 rule so then we can find the limits liek this:

Lower = \mu - 2\sigma = 373- 2(67) = 239

Upper = \mu + 2\sigma = 373+ 2(67) = 507

Lean People

Let X the random variable that represent the minutes of a population (lean people), and for this case we know the distribution for X is given by:

X \sim N(526,107)  

Where \mu=526 and \sigma=107

On this case we know that 95% of the data values are within two deviation from the mean using the 68-95-99.7 rule so then we can find the limits liek this:

Lower = \mu - 2\sigma = 526- 2(107) = 312

Upper = \mu + 2\sigma = 526+ 2(107) = 740

The interval for the lean people is significantly higher than the interval for the obese people.

Please solve this problem.<br> 2x + 34 = 56
maksim [4K]

Answer:

x = 11

Step-by-step explanation:

2x + 34 = 56

2x = 56 - 34

2x = 22

x = 22/2

x = 11
