Answer:

The area of that bedroom in real life is of 216 square feet.

Step-by-step explanation:

Real dimensions:

One of the bedrooms on the blueprint is a rectangle measuring 3 inches by 4.5 inches.

The scale is that each inch on the drawing represents 4 feet in real measure.

So the dimensions of the bedroom are:

3*4 = 12 feet by 4.5*4 = 18 feet.

What is the area of that bedroom in real life?

Rectangular bedroom, so the area is the multiplication of the dimensions.

12*18 = 216 square feet.

The area of that bedroom in real life is of 216 square feet.

Answer:

coordinates of M will be (4, [tex]\frac{13}{2}[/tex])

Step-by-step explanation:-

To find the coordinates of the midpoint, we can use this equation:-

[tex]\frac{x1 + x2}{2} , \frac{y1 + y2}{2}[/tex]

M is the midpoint of AC, where A is (2,3) and B is (6, 10)

So, x1 will be 2,

x2 will be 6

y1 will be 3

and y2 will be 10.

So, substituting these in the equation, we get:-

[tex]\frac{2 + 6}{2} , \frac{3+10}{2}[/tex]

[tex]\frac{8}{2} , \frac{13}{2}[/tex]

4, [tex]\frac{13}{2}[/tex]

So, the coordinates of the point M will be 4, [tex]\frac{13}{2}[/tex]

Answer:

x = 2.5

Step-by-step explanation:

It is given based on the topic that these are similar right triangles. Note the placement of the right angles. The 2 and x are base, while the 7.5 and 6 are hypotenuses. There are a couple of ways you can set the equation, but in this case I will set it as [tex]\frac{base}{hypotenuse}[/tex]

Set the equation:

[tex]\frac{2}{6} = \frac{x}{7.5}[/tex]

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Multiply 6 and 7.5 to both sides of the equation:

[tex]7.5 * 6 * (\frac{2}{6}) = (\frac{x}{7.5}) * 6 * 7.5\\7.5 * 2 = x * 6[/tex]

Simplify. First, multiply, then isolate the x by dividing 6 from both sides:

[tex]7.5 * 2 = 6x\\15 = 6x\\\frac{15}{6} = \frac{6x}{6} \\x = \frac{15}{6} = 2.5[/tex]

Plug in 2.5 for x in the equation to see if the equation comes out true:

[tex]\frac{2}{6} = \frac{2.5}{7.5}\\[/tex]

Multiply 6 and 7.5 to both sides of the equation:

[tex]6 * 7.5 * \frac{2}{6} = \frac{2.5}{7.5} * 7.5 * 6\\7.5 * 2 = 2.5 * 6\\15 = 15[/tex](True)

~

2.5 is your answer for x.

Answer:

1: 0.8461 = 84.61% probability that a randomly selected 1-year old boy from the population will have a weight that is less than 25 lbs.

2: 0.9994 = 99.94% probability that the mean weight for a sample of size 10 1-year-old boys will be less than 25 lbs

3: In part 2, we use the sampling distribution of the sample means, which has more values closer to the mean due to the smaller standard error, so a higher probability of finding a mean less than 25 lbs.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean of 22.8 lbs and a standard deviation of about 2.15 lbs.

This means that [tex]\mu = 22.8, \sigma = 2.15[/tex]

Part 1: Find the probability that a randomly selected 1-year old boy from the population will have a weight that is less than 25 lbs.

This is the pvalue of Z when X = 25. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{25 - 22.8}{2.15}[/tex]

[tex]Z = 1.02[/tex]

[tex]Z = 1.02[/tex] has a pvalue of 0.8461

0.8461 = 84.61% probability that a randomly selected 1-year old boy from the population will have a weight that is less than 25 lbs.

Part 2: Find the probability that the mean weight for a sample of size 10:

Now [tex]n = 10, s = \frac{2.15}{\sqrt{10}}[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{25 - 22.8}{\frac{2.15}{\sqrt{10}}}[/tex]

[tex]Z = 3.24[/tex]

[tex]Z = 3.24[/tex] has a pvalue of 0.9994

0.9994 = 99.94% probability that the mean weight for a sample of size 10 1-year-old boys will be less than 25 lbs

Part 3: Explain the difference between Part 1 and Part 2.

In part 2, we use the sampling distribution of the sample means, which has more values closer to the mean due to the smaller standard error, so a higher probability of finding a mean less than 25 lbs.

Old value: 51.09+0.91=$52.00

52(1-r)=51.09

Answer:

162√3.

Step-by-step explanation:

Area = 1/2 * p * q  where p and q are the diagonals.

Here p = 2*9 = 18 and we need to find q.

tan 60 = 0.5q/9

0.5q = 9 tan 60 = 9*√3

q = 18√3

So the area of this rhombus

Your welcome ;)

The possible numbers of riders for week 5 are option (B) 16809 and option (C) 17724 is the correct answer.

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.

Mean absolute deviation (MAD) is a way to describe variation in a data set. It is the average distance between each data value and the mean.

For the given situation,

Tim drives the Grand Avenue bus route. He records the total number of passengers each week for 4 weeks. The details are

Mean = 17,123 and

Mean absolute deviation = 611

The possible numbers of riders for week 5 that are within the mean absolute deviation can be calculated by adding and subtracting the MAD value with the mean value.

[tex]17123-611=16512[/tex]

[tex]17123+611=17734[/tex]

Thus the range should lie between [tex]16512[/tex] and [tex]17734[/tex]. The possible numbers of riders for week 5 that are within the mean absolute deviation are 16809 and 17724.

Hence we can conclude that the possible numbers of riders for week 5 are option (B) 16809 and option (C) 17724 is the correct answer.

Answer:

50.26 if you use 3.14 for pi

50.35 if you use 3.15 for pi

Step-by-step explanation:

First, we find the circumference of the circle in the center.

(15 - 3 - 3)/2 = 4.5

4.5 is the radius

Equation for circumference: 2*pi*r

2*pi*4.5

9pi

Depending on where you normally use 3.14 or 3.15 for pi changes the answer but for this example I will use 3.14

The circumference of the circle is 28.26

Next, add the other sides of the figure.

28.26 + 3 + 3 + 3 + 3 + 5 + 5 = 50.26
