Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. Midpoint (15, -8), endpoint (16, -3). What is the other endpoint?
Answer:
the other endpoint is [tex](14,-13)[/tex]
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two points is equal to
[tex]M(\frac{x1+x2}{2},\frac{y1+y2}{2})[/tex]
Let
[tex](x1,y1)=(16,-3)[/tex]
so
[tex](16+x2)/2=15[/tex] -----> [tex]x2=30-16=14[/tex]
[tex](-3+y2)/2=-8[/tex] -----> [tex]y2=-16+3=-13[/tex]
therefore
the other endpoint is [tex](x2,y2)=(14,-13)[/tex]

Therefore, The total volume of the space inside the steps is 2880 cubic inches.
Holly has a rectangular garden that measures 12 m wide by 14 m long. She wants to increase the area to 255 m? by increasing the width and length by the same amount. What will be the length (longer dimension) of the new garden? Enter your answer in the box.
Answer:
255 square meters
Step-by-step explanation:
Present area = 12 * 14 = 168 square meters
The area has to increase by a factor of 255 / 168 = 1.5178571429
Therefore, the width and length are increased by a factor of the
square root of 1.5178571429 = 1.2320134508
So the width becomes
12 * 1.2320134508 = 14.7841614091
and the length becomes
14 * 1.2320134508 = 17.2481883107
That's roughly 14.78 by 17.25 and the area equals
14.78 * 17.25 = 255 square meters

Consider the triangle. Find the length of the hypotenuse, c
The length of the hypotenuse is (blank) cm.
Answer:
The length of the hypotenuse is 26 cm.
Step-by-step explanation:
In order to find the hypotenuse in this right triangle you can use the Pythagoras' Theorem.
The Pythagorean Theorem tells us that the relationship in every right triangle is:
[tex]a^{2}+b^{2}=c^{2}[/tex],
See the picture attached to know what is the meaning of constants a, b and c.
In the triangle given, a = 24cm and b = 10 cm, now you can use the Pythagorean Theorem to find c or the hypotenuse.
[tex]a^{2}+b^{2}=c^{2}\\ 24^{2}+10^{2}=c^{2}\\ 576+100=c^{2}\\ c^{2}=676\\\mathrm{For\:}x^2=\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{\left(a\right)},\:\:-\sqrt{\left(a\right)}\\ x_{1}=\sqrt{676}, x_{2}=-\sqrt{676} \\ x_{1}=26, x_{2}=-26[/tex]
Because we are finding the distance between points AB, this distance cannot be negative, so the answer is the length of the hypotenuse is 26 cm.

75, 87, 49, 68, 75, 84, 98 (mean, median mode or range) Please help!!
Final answer:
The mean is 83, median is 75, mode is 75, and range is 49 for the set of numbers 75, 87, 49, 68, 75, 84, 98.
Explanation:
The given set of numbers is: 75, 87, 49, 68, 75, 84, 98.
To find the mean, add up all the numbers and divide the sum by the total count of numbers: (75 + 87 + 49 + 68 + 75 + 84 + 98) / 7 = 83.
To find the median, arrange the numbers in ascending order and find the middle number: 49, 68, 75, 75, 84, 87, 98. So the median is 75.
To find the mode, identify the number that appears most frequently in the set. In this case, 75 appears twice, which is the highest frequency. Therefore, the mode is 75.
The range is calculated by subtracting the smallest number from the largest number in the set: 98 - 49 = 49.

"Underwater weddings Inc. offers two kinds of weddings, Caribbean weddings and backyard swimming pool weddings. This last weekend, the company held 5 pool weddings and 2 Caribbean weddings. If the company took in $55,000, and Backyard Pool weddings cost $10,000 less than Caribbean weddings, how much does each kind of wedding cost?"
I will mark whoever can give me an explanation as well brainliest~! Thank you, and have a great day!
The cost of each Caribbean wedding is $15,000 and the cost of each backyard swimming pool wedding is $5,000.
To solve the word problem involving Underwater Weddings Inc., we can let the cost of a Caribbean wedding be x dollars. Since a backyard swimming pool wedding costs $10,000 less, its cost would be x - 10,000 dollars.
The problem states that there were 5 pool weddings and 2 Caribbean weddings, and the total income was $55,000. This gives us the equation:
5(x - 10,000) + 2x = 55,000
Now, we solve for x:
5x - 50,000 + 2x = 55,000
7x = 55,000 + 50,000
7x = 105,000
x = 105,000 / 7
x = 15,000
Caribbean weddings cost $15,000 each.
Therefore, backyard swimming pool weddings cost $15,000 - $10,000 = $5,000 each.
Juan’s game board is a square with sides that are 50 cm long. The area of the large circle is about 1,963.5 square cm.
What is the geometric probability that Juan will score more than 0 points?
Answers are in the pic
Answer:
C) 0.785
Step-by-step explanation:
I am assuming that hitting the blue area will result in 0 points.
The area of said square is 50*50, which is 2500 cm².
The chances of scoring >0 points is the chance of hitting the circle.
That is 1963.5/2500.
Therefore, the chance is 0.7854, or 0.785.
Final answer:
The geometric probability that Juan will score more than 0 points is 78.54%.
Explanation:
The geometric probability is the probability associated with geometrical events, such as the probability of a point landing in a certain region. In this case, the event is Juan scoring more than 0 points on his game board. To find the geometric probability, we need to compare the area of the circle to the area of the square. The area of the square is 50 cm x 50 cm = 2500 square cm. The probability of Juan scoring more than 0 points is then the area of the circle (1963.5 square cm) divided by the area of the square (2500 square cm), which equals 0.7854 or 78.54%.

How many 30 degree angles are in a 150 degree angle? Use repeated subtraction to solve.
150 minus 30 equals 120 but i did 150/30 and got 5
To find the number of 30 degree angles in a 150 degree angle using repeated subtraction, subtract 30 from 150 until reaching 30 and count the number of times you were able to subtract. In this case, there are four 30 degree angles in a 150 degree angle.
Explanation:To determine how many 30 degree angles are in a 150 degree angle using repeated subtraction, we start by subtracting 30 from 150 until we can no longer subtract without going negative. Each time we subtract 30, we count the number of times we were able to subtract. So, 150 - 30 = 120, 120 - 30 = 90, 90 - 30 = 60, and 60 - 30 = 30. We were able to subtract 30 four times before reaching 30, so there are four 30 degree angles in a 150 degree angle.

An elevator has a placard stating that the maximum capacity is 23252325 lblong dash—1515 passengers. So, 1515 adult male passengers can have a mean weight of up to 2325 divided by 15 equals 155 pounds.2325/15=155 pounds. If the elevator is loaded with 1515 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 155155 lb. (Assume that weights of males are normally distributed with a mean of 161 lb161 lb and a standard deviation of 31 lb31 lb.) Does this elevator appear to be safe?
Answer:
0.7734; no, it does not.
Step-by-step explanation:
To find this probability we will use a z-score. We are dealing with the probability of a sample mean being larger than a given value; this means we use the formula
[tex]z=\frac{\bar{X}-\mu}{\sigma \div \sqrt{n}}[/tex]
Our x-bar in this problem is 155, as that is the sample mean we are trying to find the probability of. Our mean, μ, is 161 and our standard deviation, σ, is 31. Our sample size, n, is 15. This gives us
[tex]z=\frac{155-161}{31\div \sqrt{15}}=\frac{-6}{8.0042}=-0.75[/tex]
Using a z table, we see that the area under the curve less than this, corresponding with probability less than this value, is 0.2266. This means that the probability of the sample mean being larger than this is
1-0.2266 = 0.7734, or 77.34%.
Since there is a 77.34% chance of the passengers having a mean weight that is too heavy, this elevator is not safe.
The probability that the elevator is overloaded using the normal distribution principle is 0.7870
Given the Parameters :
Mean, μ = 161Standard deviation, σ = 31 Sample size, n = 15X = 155Using the relation :
Zscore = (xbar - μ) ÷ (σ/√(n))
Zscore = (155 - 161) ÷ (31/√15)
Zscore = - 0.796
The probability that lift is overloaded can be expressed thus :
P(Z ≥ - 0.796) = 1 - P(Z ≤ - 0.796)
Using a normal distribution table ; PP(Z ≤ - 0.796) = 0.2130
P(Z ≥ - 0.796) = 1 - 0.2130
P(Z ≥ - 0.796) = 0.7870
Therefore, the probability that weight is overloaded is 0.7870

Step-by-step explanation:
we have
[tex]5\frac{4}{5} \ cups[/tex]
Convert to an improper fraction
[tex]5\frac{4}{5}=\frac{5*5+4}{5}=\frac{29}{5}\ cups[/tex]
[tex]=(\frac{5}{5}+\frac{5}{5}+\frac{5}{5}+\frac{5}{5}+\frac{5}{5}+\frac{4}{5})\ cups[/tex]

The fraction represent (25/5) cups of milk plus (4/5) cups of milk left in a carton
or
The fraction represent 5 cups of milk plus (4/5) cups of milk left in a carton
5 4/5 cups of milk is equivalent to 29/5 cups when written as an improper fraction. This represents that there are a total of 29 fifths of a cup of milk in the carton.
Explanation:To convert 5 4/5 cups of milk to an improper fraction, you multiply the whole number by the denominator of the fraction and add the numerator. Here, 5 is the whole number, 4 is the numerator, and 5 is the denominator. So, you calculate (5 × 5) + 4 = 25 + 4 = 29. Therefore, 5 4/5 cups is the same as 29/5 cups of milk in improper fraction form.
In this situation, the improper fraction 29/5 represents the total number of fifths of a cup of milk in the carton. Since there are five fifths in a whole cup, and we have 5 whole cups plus an additional 4 fifths, we have a total of 29 fifths of a cup of milk.
Pete’s parents are offering to pay him a weekly allowance for doing his chores. They’ve given him two different payment options for a period of 15 weeks.
Option 1: $20 every week
Option 2: A penny in the first week, and then double the amount from the previous week in each week after that. So, 1 penny in the first week, 2 pennies in the second week, 4 pennies in the third week, and so on.
Which one is the better option for Pete? Explain why.
Find the total of each option to see which one is better.
Option 1:
$20 every week for 15 weeks = 15 x 20 = $300 total.
Option 2:
Week 1 you have 1 penny.
Week 2 you would have 1 +2 = 3 pennies.
Week 3 you would have 3 + 4 = 7 pennies.
From this we can see a pattern of 2^x - 1 where x is the number of weeks.
So in 15 weeks he would have 2^15 - 1 = 32767 pennies.
100 pennies equal $1
32767 / 100 = $327.67
The second option is better because he ends up with more money.

Answer:
A) x ≥ 0.074; B) x ≥ 0.108; C) x ≤ 0.006; D) 0.04 ≤ x ≤ 0.108
Step-by-step explanation:
68% of data will fall within 1 standard deviation of the mean; 95% of data will fall within 2 standard deviations of the mean; and 99.7% of data will fall within 3 standard deviations of the mean.
Breaking this down, we find that 34% of data fall from the mean to 1 standard deviation above the mean; 13.5% of data fall from 1 standard deviation above the mean to 2 standard deviations above the mean; 2.35% of data fall from 2 standard deviations above the mean to 3 standard deviations above the mean; and 0.15% of data fall above 3 standard deviations above the mean.
The same percentages apply to the standard deviations below the mean.
The highest 50% of data will fall from the mean to the end of the right tail. This means the inequality for the highest 50% will be x ≥ 0.074, the mean.
The highest 16% of data will fall from 1 standard deviation above the mean to the end of the right tail. This means the inequality for the highest 16% will be x ≥ 0.074+0.034, or x ≥ 0.108.
The lowest 2.5% of data will fall from 2 standard deviations below the mean to the end of the left tail. This means the inequality for the lowest 2.5% will be x ≤ 0.074-0.034-0.034, or x ≤ 0.066.
The middle 68% will fall from 1 standard deviation below the mean to 1 standard deviation above the mean; this means the inequality for the middle 68% will be
0.074-0.034 ≤ x ≤ 0.074+0.034, or
0.04 ≤ x ≤ 0.108
The cutoff values using the 68-95-99.7 Rule for the given mutual funds data are calculated. The highest 50% lies between 4.0% and 10.8%, the highest 16% lies between 0.6% and 14.2%, the lowest 2.5% lies between -2.8% and 17.8%, and the middle 68% lies between 4.0% and 10.8%.
Explanation:The cutoff values can be found using the 68-95-99.7 Rule, which states that approximately 68 percent of the data lies within one standard deviation of the mean, 95 percent lies within two standard deviations, and 99.7 percent lies within three standard deviations. With a mean of 7.4% and a standard deviation of 3.4%, we can determine the cutoff values:

What is the measure of ∠T, rounded to the nearest degree? 22° 33° 43° 68°
Answer:
22 degrees to the nearest degree.
Step-by-step explanation:
Use the Cosine Rule
3^2 = 5^2 + 7^2 - 2*5*7*cos T
9 = 74 - 70 cos T
cos T = (74-9)/ 70
cos T = 65/70
m < T = 21.8 degrees.
Answer:
∠T=22°
Step-by-step explanation:
Given triangle RST with sides 5 cm, 7 cm, 3 cm.
If all sides are given and find the missing angle, we use cosine rule
[tex]CosA=\frac{b^{2}+c^{2} -a^{2}}{2bc}[/tex]
Where,
sides are a, b, c and angle A, B, & C are opposite angles respectively.
So,
[tex]CosT=\frac{r^{2}+s^{2} -t^{2}}{2rs}[/tex]
[tex]cosT=\frac{25+49-9}{70}[/tex]
[tex]cosT=\frac{65}{70} =\frac{13}{14}[/tex]
T = 21.79°≈ 22°
That's the final answer.
