The three sides of a triangular lot are represented by x , 2 x , and 3 x + 2. Find each side if the perimeter of the triangular lot is 362 feet. The lengths of the sides of the triangle are :
Answer:
60 ft, 120 ft, 182 ft
Step-by-step explanation:
Hi there,
To find the perimiter of a polygon, you need to add of all of the sides.
So, let's do that:
x + 2x + 3x+2
Since we are given the perimeter, we make what we just did above, equal to the perimeter
x + 2x + 3x +2 = 362
Combine lke terms...
6x + 2 = 362
Subtract 2 from both sides to start to isolate the variable...
6x = 360
Divide both sides by 6 to isolate x...
x = 60
But we're not done yet...
The length of the first side is 60 ft, the length of the second side is 2*60 which is 120 ft, and the length of the third side is 3*60 + 2 which is 182 ft.
Let's check...
Does 60 + 120 + 182 = 362?
362 = 362
Our answers are right

how old am i if 500 reduced by 4 times my age is 184
Answer:
79 years old
Step-by-step explanation:
Let's say your age is x.
The problem says "500 reduced by 4 times my age is 184", so we convert this to math:
- "4 times my age" ⇒ 4 * x = 4x
- "500 reduced by" ⇒ 500 - (something)
- "500 reduced by 4 times my age" ⇒ 500 - 4x
- "is 184" ⇒ = 184
- "500 reduced by 4 times my age is 184" ⇒ 500 - 4x = 184
Now, we simply solve for x:
500 - 4x = 184
4x = 500 - 184 = 316
x = 79
Thus, you are 79 years old.

Kathy and her brother Clay recently ran in a local marathon. The distribution of finishing time for women was approximately normal with mean 259 minutes and standard deviation 32 minutes. The distribution of finishing time for men was approximately normal with mean 242 minutes and standard deviation 29 minutes. (a) The finishing time for Clay was 289 minutes. Calculate and interpret the standardized score for Clay's marathon time. Show your work. (b) The finishing time for Kathy was 272 minutes. What proportion of women who ran the marathon had a finishing time less than Kathy's? Show your work. (c) The standard deviation of finishing time is greater for women than for men. What does this indicate about the finishing times of the women who ran the marathon compared to the finishing times of the men who ran the marathon?
Part a)
We have that,the distribution of finishing time for men was approximately normal with mean 242 minutes and standard deviation 29 minutes.
We want to calculate and interpret the standardized score for Clay's marathon time, if the finishing time for Clay was 289 minutes.
We use the formula:
[tex]z = \frac{x - \bar x}{s} [/tex]
we substitute the values to get:
[tex]z = \frac{289 - 242}{29} [/tex]
[tex]z = 1.62[/tex]
This means Clay's finishing time is 1.62 standard deviation above the mean finishing time.
Part b)
This time, we have that, the distribution of finishing time for women was approximately normal with mean 259 minutes and standard deviation 32 minutes.
We want to find the proportion of women who ran the marathon that had a finishing time less than Kathy if the finishing time for Kathy was 272 minutes.
We first calculate the z-score to get:
[tex]z = \frac{272 - 259}{32} = 0.41[/tex]
From the normal standard distribution table P(z<0.41)=0.6591.
This means 65.91% of women had a finishing time less than Kathy's finishing time.
Part c
The standard deviation of a data set tells us how far away the individual data are from the mean.
If the standard deviation of finishing time is greater for women than men, it means the finishing time for women are farther from the mean finishing time than that of men.
Using the normal distribution, it is found that:
a) His standardized score was of z = 1.6, which means that his finishing time is of 1.6 standard deviations above the mean finishing time for all men.
b) 0.6591 = 65.91% of women who ran the marathon had a finishing time less than Kathy's.
c) The higher standard deviation shows that the finishing times of the women who ran the marathon are more spread out compared to the finishing times of the men who ran the marathon.
In a normal distribution 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]
It 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, which is the percentile of X.Item a:
For men, mean of 242 minutes, thus [tex]\mu = 242[/tex].Standard deviation of 29 minutes, thus [tex]\sigma = 29[/tex].The z-score is found when X = 289, thus:[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{289 - 242}{29}[/tex]
[tex]Z = 1.6[/tex]
His standardized score was of z = 1.6, which means that his finishing time is of 1.6 standard deviations above the mean finishing time for all men.
Item b:
For women, mean of 259 minutes, thus [tex]\mu = 259[/tex]Standard deviation of 32 minutes, thus [tex]\sigma = 32[/tex].The proportion is the p-value of Z when X = 272, thus:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{272 - 259}{32}[/tex]
[tex]Z = 0.41[/tex]
[tex]Z = 0.41[/tex] has a p-value of 0.6591.
0.6591 = 65.91% of women who ran the marathon had a finishing time less than Kathy's.
Item c:
The higher standard deviation shows that the finishing times of the women who ran the marathon are more spread out compared to the finishing times of the men who ran the marathon.

Solve the following quadratic equations using completing the square x2 – 8x – 34 = 0
Answer:
x=4± 5sqrt(2)
Step-by-step explanation:
x^2 – 8x – 34 = 0
To complete the square Add 34 to each side
x^2 -8x -34+34=0+ 34
Take the coefficient of x, and divide by 2
-8/2 =-4
Then square it and add it to each side
(-4)^2 =16
x^2 – 8x +16 = 34+16
x^2 – 8x +16 = 50
We replace the left side with (x + the coefficient of x/2)^2
(x -4)^2=50
Take the square root of each side
sqrt((x -4)^2)=±sqrt(50)
x-4 = ±sqrt(25*2)
x-4 = ±sqrt(25)*sqrt(2)
x-4 = ±5sqrt(2)
Add 4 to each side
x=4± 5sqrt(2)
Answer:
4 + 5sqrt(2), 4 - 5sqrt(2)
Step-by-step explanation:
x² - 8x - 34 = 0
x = [-(-8) +/- sqrt((-8)² - 4(1)(-34))]/2

The lifespans of zebras in a particular zoo are normally distributed. The average zebra lives 20.5years; the standard deviation is 3.9 years. Use the empirical rule (68-95-99.7%)to estimate the probability of a zebra living less than 32.2 years.
Answer:
Using the empirical rule, the probability of a zebra living less than 32.2 years is about [tex] \\ P(z<3) = P(x<32.2) = 0.9985[/tex] or about 99.85%.
Step-by-step explanation:
Roughly speaking, the empirical rule tells us that, in a normal distribution, the distance of one standard deviation from the mean, above and below it, contains approximately 68% of the observations of the normally distributed data; two standard deviations from the mean, above and below it, 95% of the data, and, finally, the distance of three standard deviations from the mean, above and below it, contains 99.7% of the data, approximately.
To estimate probabilities with this rule, we need to use, at least, two concepts: the standard normal distribution and the z-scores. A standard normal distribution is a normal distribution with mean = 0 and standard deviation = 1. It represents standardized data. This standardized data are those coming from a normal distribution and commonly called raw data. The way to standardized them is using the z-scores:
[tex] \\ z = \frac{x - \mu}{\sigma}[/tex] [1]
Where
x represents raw data. In this case, x = 32.2 years.
[tex] \\ \mu[/tex] is the population mean. In this case, [tex] \\ \mu = 20.5[/tex] years.
[tex] \\ \sigma[/tex] is the population standard deviation. In this case, [tex] \\ \sigma = 3.9[/tex] years.
Then, using [1], we "transform" the raw score into a z-score (a standardized value) and then use this to find the corresponding probability using the standard normal distribution (or the cumulative standard normal distribution to be more precise), available in any Statistics book or on the Internet.
However, applying the empirical rule, we can estimate those probabilities faster but in an approximate way.
Let us take the corresponding z-score:
[tex] \\ z = \frac{x - \mu}{\sigma}[/tex]
[tex] \\ z = \frac{32.2 - 20.5}{3.9}[/tex]
[tex] \\ z = \frac{11.7}{3.9}[/tex]
[tex] \\ z = 3[/tex]
That is, the value z = 3 tells us the raw score 32.2 years is three standard deviations from the mean. In other words, 99.7% of the values are between z = -3 and z = 3. However, we are asked for P(z<3). The remaining area is below z = -3 and above z = 3. Since the normal distribution is symmetrical, we have to divide the remaining area by 2. That is, (1 - 0.997)/2 = 0.003/2 = 0.0015.
The area below z = -3 is, therefore, 0.0015, as well as above z = 3 or P(z<-3) = P(z>3) = 0.0015. The only area that not correspond to P(z<3) is P(z>3). As a result, we need to add the area below z = -3 (0.0015) to the value of 0.997 to finally have P(z<3).
Then
[tex] \\ P(z<3) = P(x<32.2) = 0.997 + P(z<-3)[/tex]
[tex] \\ P(z<3) = P(x<32.2) = 0.997 + 0.0015[/tex]
[tex] \\ P(z<3) = P(x<32.2) = 0.9985[/tex]
Thus, using the empirical rule, the probability of a zebra living less than 32.2 years is about [tex] \\ P(z<3) = P(x<32.2) = 0.9985[/tex].
In the graph below, we have a representation of the area below z = 3 or P(z<3) = P(x<32.2) is, approximately, 0.9985 or 99.85%.
Notice that using the cumulative standard normal table, as explained before, we have that P(z<3) = 0.99865.
Answer: 68, if the question asks between 16.6 and 24.4 years. 99.85, if the question asks for less.

Grace earns $5 each times she walks her neighbor's dog. She walks the dog 5 times in one week. Then she spends $7 on a book and $9 on a building set. Write an equation to represent how much money Grace has left, m.
Answer:
$5 (5) - ($7+$9)=m
$25 - $16 =m
Step-by-step explanation:
$5 (5) - (7+9)=m
$25 - 16 =m
The equation to represent how much money Grace has left is:
m = $25 - $7 - $9
m = $25 − $16
m = $9
How do we represent the event in the form of an equation?Grace earns $5 for each dog walk.
She walks the dog 5 times in one week, so she earns 5 walks * $5/per walk = $25.
She spends $7 on a book and $9 on a building set, so she spends a total of $7 + $9 = $16.
To find out how much money Grace has left, m, we subtract her total spending from her earnings.

There are 30 students in Mrs. Taylor's kindergarten class. If there are twice as many students with blond hair as with blue eyes, 6 students with blond hair and blue eyes, and 3 students with neither blond hair nor blue eyes, how many students have blue eyes?
Answer:
11
Step-by-step explanation:
Let e represent the number of students with blue eyes. Then the number of students with blond hair is 2e. The total number of students is ...
3 + e + 2e -6 = 30
We subtracted 6 because the expressions e and 2e cause the 6 students with both blond hair and blue eyes to be counted twice.
3e = 33 . . . . add 3 and simplify
e = 11
11 students have blue eyes.
In the given problem, using the logical reasoning to deduce from the given facts, it can be determined that there are 10 students in Mrs. Taylor's class that have blue eyes.
Explanation:To find out how many students in Mrs. Taylor's kindergarten class have blue eyes, we need to use the information given in the problem and make a series of logical deductions.
First, we know that there are twice as many students with blond hair as with blue eyes. Let's say the number of students with blue eyes is x. This implies that the number of students with blond hair is 2x.
We also know that there are 6 students with both blond hair and blue eyes. So, those students are included in both of our previous counts. Therefore, we need to subtract 6 from each count to get the number of students with only one of those attributes.
So far, this gives us x - 6 students with only blue eyes and 2x - 6 students with only blond hair. We know that there are 3 students with neither attribute, so the total number of students is (x - 6) + (2x - 6) + 6 (students with both attributes) + 3 (students with neither attribute) = 30.
Adding these together gives us 3x = 30, so x = 30/3 = 10. Therefore, there are 10 students with blue eyes.

You have been asked to determine where a water works should be built along a river between Chesterville and Denton to minimize the total cost of the project. The pipe to Chesterville costs $3000 per mile and the pipe to Denton costs $7000 per mile. Find the length of each pipe so that the total cost is a minimum. What is the cost?
Answer:
Length of pipe to Chesterville is 8.376 miles and
Length of pipe to Denton is 5.46 miles
Step-by-step explanation:
Here we have
The distance of Chesterville from the river is 3 miles, while the distance of Denton from the river is 5 miles
The bank of the river is 10 miles long
Therefore, we have
If x is the distance from the point directly opposite to Chesterville to the location of the water works, the equation is;
Cost to Chesterville = [tex]3000\times \sqrt{x^2 + 3^2}[/tex]
Cost to Denton = [tex]7000\times \sqrt{(10-x)^2 + 5^2}[/tex]
Total cost is then;
[tex]7000\times \sqrt{(10-x)^2 + 5^2} + 3000\times \sqrt{x^2 + 3^2}[/tex]
We differentiate the above equation and equate it to zero to get the minimum cost as
[tex]\frac{\mathrm{d} (7000\times \sqrt{(10-x)^2 + 5^2} + 3000\times \sqrt{x^2 + 3^2})}{\mathrm{d} x}[/tex] = 0
[tex]7000\frac{2x-20}{2\sqrt{x^2-20x+125} } +3000\frac{2x}{2\sqrt{x^2+9} } = 0[/tex]
[tex]3500\frac{2x-20}{\sqrt{x^2-20x+125} } = -1500\frac{2x}{\sqrt{x^2+9} }[/tex]
[tex]3500\frac{\sqrt{x^2+9}}{\sqrt{x^2-20x+125} } = -1500\frac{2x}{2x-20 }[/tex]
[tex]x^4-20x^3+10.54x^2-22.05x+110.25 =0[/tex]
Solving the quartic equation we get
x = 7.82 miles
Therefore the length of is given as
Length of pipe to Chesterville [tex]\sqrt{7.82^{2} +3^2 } = 8.376 \, miles[/tex]
Length of pipe to Denton = [tex]\sqrt{(10-7.82)^2 + 5^2} = 5.46 \, miles[/tex].

One hundred and 50 people were asked whether they like to see comedies or dramas and whether or not I buy popcorn from for the movie out of 90 people that like comedies they bought popcorn day or 40 people that said they do not buy popcorn
Answer: a) 0.6, b) [tex]\dfrac{4}{15}[/tex]
Step-by-step explanation:
Since we have given that
Total number of people were surveyed = 150
Number of people that like comedies they bought popcorn that day = 90
Number of people that said they do not buy popcorn = 40
So, Probability of getting who like comedies and bought popcorn = [tex]\dfrac{90}{150}=\dfrac{3}{5}=0.6[/tex]
Probability of getting who said they do not buy popcorn = [tex]\dfrac{40}{150}=\dfrac{4}{15}[/tex]
Hence, a) 0.6, b) [tex]\dfrac{4}{15}[/tex]

-6.75 is a rational number since it can be expressed as a fraction of two integers. It's also a real number, but it's not a natural, whole, integer, or irrational number.
Explanation:The number -6.75 is a Rational Number. Here's why:
A Natural Number is a number that is a positive integer, which would not include -6.75 because it is negative. A Whole Number is a number without fractional components, so -6.75 isn't a whole number as it has a fractional part. An Integer is a whole number that can be positive, negative, or zero, but does not include fractions or decimals, therefore, -6.75 isn't an integer. A Rational Number is a number that can be expressed as a fraction of two integers, and since -6.75 can be written as -675/100, it falls into this category. Since all rational numbers are included in the Real Number set, -6.75 is also a real number. However, an Irrational Number cannot be expressed as a ratio of two integers, which means that -6.75 isn't irrational.

A cylinder has a radius of 30.8 centimeters and height of 20.5 centimeters. Which measurement is closest to the lateral surface area of the cylinder in square centimeters
To find the lateral surface area of a cylinder with a radius of 30.8 cm and a height of 20.5 cm, use the formula 2πrh. The calculation gives a result of approximately 3981.86 square centimeters.
Explanation:The question asks for the closest measurement to the lateral surface area of a cylinder with a radius of 30.8 centimeters and a height of 20.5 centimeters. To find the lateral surface area of the cylinder, we use the formula: Lateral Surface Area = 2πrh, where 'r' is the radius, and 'h' is the height of the cylinder. Substituting the given values,
we get Lateral Surface Area = 2 × 3.14 × 30.8 cm × 20.5 cm.
Calculating this, we find:
Lateral Surface Area = 3981.864 square centimeters. Therefore, the closest measurement to the lateral surface area of the cylinder is 3981.86 square centimeters.
