Find the equation of a circle with the Endpoints of a diameter: (11, −5), (3, 15)
Answer:
(x - 7)² + (y - 5)² = 116
Step-by-step explanation:
equation of a circle:
(x - h)² + (y - k)² = r²
where (h,k) is the centre and r is the radius
centre is the midpoint of the diameter:
(h,k) = (11+3)/2 , (-5+15)/2
(h,k) = (7,5)
diameter = sqrt[(15--5)² + (3-11)²]
diameter = sqrt(464) = 4sqrt(29)
radius = ½ diameter
radius = 2sqrt(29)
r² = 116
equation:
(x - 7)² + (y - 5)² = 116
Answer:
[x-7]^2 + [y-5]^2= 116
Step-by-step explanation:
General equation of a circle is
[x2 - xo]^2 + [y2- yo]^2 = r^2
Where xo and yo are coordinates of the circle at the origin.
But xo = [x2 + x1]/2
= 11 + 3 / 2 = 7
yo = [y2 + y1] / 2 = [-5 + 15] /2 = 5
x2= 11, x2= 3; y1= -5, y2= 15
[11-7]^2 + [15-5]^2 =
16+ 100=116 = r^2
From the expression below;
[x2-xo]^2 + [y2-yo] ^2 = r^2
[x1-xo]^2 + [y1-yo] ^2 = r^2
[x-7]^2 + [y-5]^2= 116

"Eat For 10 Hours. Fast For 14. This Daily Habit Prompts Weight Loss, Study Finds"
This is the title of an NPR article about a 2019 study that recruited 19 overweight adults diagnosed with metabolic syndrome (elevated blood sugar, elevated cholesterol levels, high blood pressure). Participants were asked to restrict any eating to a period of just 10 hours each day. The study found a statistically significant reduction in body weight after 12 weeks of this eating pattern.
1. To be able to conclude that a time-restricted eating pattern causes a weight loss in this population on average, we would need to ___________.
O use a much larger sample than what this study used
O collect weight-loss data on all adults, not just adults with metabolic syndrome
O find a significant weight-loss difference for participants that would be randomly assigned to time-restricted eating or regular eating
O collect weight-loss data on the entire population of adults with metabolic syndrome
O make sure that the study found a very small P-value and check that the conditions for inference were all met
Answer:
Option A
Step-by-step explanation:
To conclude that a time-restricted eating pattern causes a weight loss in this population on average, we would need to use a much larger sample than the 19 actually used in the study to get an unbiased conclusion and to also ensure that the sample itself and whatever result produced is a true representation of this particular population itself.
Please Help.... 50 points.
Answer:
94%
Step-by-step explanation:
We need to look at the graph. Olive wants the probability that 20 or more of the 50 babies were female. Looking at the graph, the x-axis is "number of females born out of 50 babies". We want to find the sum of all the ones that are at least 20, or 20 and above.
The numbers above the bars represents how many of each case there are. Above the bar labelled 20, there is the number 11, and so on. So, our sum is:
11 + 17 + 14 + 23 + 16 + 29 + 16 + 23 + 14 + 6 + 9 + 3 + 1 + 2 + 1 + 1 + 1 = 187
In total, there are 200 cases, so our probability is 187 / 200 = 93.5% ≈ 94%.
The answer is thus A.
Step-by-step explanation:
Step 1: Count up how many babies are more than 20
[tex]11 + 17 + 14 + 23+16+29+16+23+14+6+9+3+1+2+1+1+1[/tex]
[tex]187[/tex]
[tex]187 / 200[/tex] ← Will give us percentage of the probability that 20 or more of the 50 babies were born female.

data set A is {30, 45, 32, 50, 33, 40, 44, 32}. Data set B is {28, 43, 30, 48, 35, 42, 46, 34}. which statement best compares the two data sets
Answer:
the mean in set B is equal to the mean in set A (option C)
Question:
The question is incomplete as the answer choices were not given.Let's consider the following question:
Data set A is {30, 45, 32, 50, 33, 40, 44, 32}. Data set B is {28, 43, 30, 48, 35, 42, 46, 34}. which statement best compares the two data sets?
a) median for set A is equal to the median for set B
b) Range for set A is greater than range for set B
c) The mean in set B is equal to the mean in set A
Step by step explanation:
We can describe a data set using four ways:
Center, spread, shape and unusual features.
Let's consider the center and spread.
Center: This is the median of the distribution.
Spread: This is the variation of the data set. If the range is wide, the spread is larger and If the range is small, the spread is smaller.
Rearranging the data set:
A = {30, 32, 32, 33, 40, 44, 45, 50}
B = {28, 30, 34, 35, 42, 43, 46, 48}
From the data:
The median for set A = (33+40)/2 = 73/2= 36.5
The median for set B = (35+42)/2 = 77/2= 38.5
Range = highest value - lowest value
The data ranges from 30 to 50 (range = 20) for A
The data ranges from 28 to 48 (range = 20) for B
Mean for set A = (30+32+32+33+40+4445+50)/8 = 306/8 = 38.25
Mean for set B = (28+30+34+35+42+43+46+48)/8= 306/8 = 38.25
In both data set the mean is equal to 38.25.
Therefore the statement that best compares the two data sets is the mean in set B is equal to the mean in set A (C)
Answer:
I think it is The mean for data set B is greater that the mean for data set A

The percent markup on a video game is known to be 108% based on cost. If the seller paid $35 for one, then what would be the corresponding percent markup based on the sale price? (Round to the nearest tenth percent)
Answer: 48.1%
Step-by-step explanation:
The percent markup is defined as:
PM = (gross benefit/cost per unit.)*100%
We know that the cost per unit is $35
then we have:
108% = (gross benefit/$35)*100%
gross benefit = (108%/100%)*$35 = $37.8
This means that a game is selled by $35 + $37.8 = $72.8
Now we have:
Markup percent = (gross benefit/selling price)*100% = ($35/$72.8)*100% = 48.1%
The ages of Rohit and James are in the ratio 2 : 5. In 9 years, the ratio of their ages will be 5 : 8. Find their present ages.
Answer:
Step-by-step explanation:
I don't say you have to mark my ans as brainliest but if you think it has really helped you then plz don't forget to thank me...
Answer:
Rohit is 6 years old
James is 15 years old
Step-by-step explanation:
Rohit : James 2 : 5
the difference between their units is 3
Now we add the 9 years
5 : 8the difference between their units should be 3 because they both age every year. the question was nice enough to give to same amount of units
Now we subtract James's original 'unit age' from his new one
8u - 5u = 3 uWe also need to make sure the difference between Rohit's original 'unit age' is 3
5u - 2u = 3uthis 3 units represent the 9 years that have passed
3 units = 9 yearsTo find James's age all we ahve to find is their original unit number
James (5 units) -> 3 × 5 = 15same for Rohit
Rohit (3 units) -> 3×3 = 9hence, Rohit's and James's ages are 9 and 15 respectivelyA seabird rescue center has a special habitat for birds that will be released soon. The habitat is shaped like a rectangular prism. The habitat has a ground area of 2,000 square meters that is covered in grass and sand. The height of the habitat is 9 meters. What is the volume of the bird habitat? This is not collage level.
Answer:
18,000 Cubic meters
Step-by-step explanation:
Since volume is lwh and the area of the ground is lw and it gives you the height, You just multiply The area of the ground, 2,000 m, and the height, 9, to find the volume. 9 x 2,000= 18,000.

If one zero is irrational, the other zero is
Answer:
rational
Step-by-step explanation:
The correct statement is:
c. The other zero can be either rational or irrational.
A quadratic equation with integer coefficients can have two distinct zeros, and if one of the zeros is irrational, the other zero can be either rational or irrational.
The nature of the zeros depends on the specific values of the coefficients in the quadratic equation.
A quadratic equation with integer coefficients can be written in the form: [tex]ax^2 + bx + c = 0[/tex], where a, b, and c are integers.
The solutions to this equation can be found using the quadratic formula:
[tex]\mathrm x = \frac{\mathrm{-b}\pm \sqrt{\mathrm b^2-4\mathrm a \mathrm c} }{2 \mathrm a}[/tex]
If one zero is irrational, it means that one of the solutions obtained from the quadratic formula is an irrational number.
However, the other solution can still be either rational or irrational.
The discriminant, [tex]b^2 - 4ac[/tex], determines the nature of the solutions.
If the discriminant is a perfect square, both solutions will be rational.
If the discriminant is not a perfect square, one solution will be irrational, and the other may be either rational or irrational.
Therefore, it is possible for the other zero to be rational or irrational, depending on the specific values of a, b, and c in the quadratic equation.
Thus, option (c) is the correct answer.

(2x-23) value of angle x
Answer
65 degrees
Step-by-step explanation:
The value of x for which Angle B is supplementary to Angle A would be x = 26.17.
Used the definition of supplementary angle that states,
The sum of supplementary angles in any figure gives 180 degrees always.
Given that,
Angle A measures (2x - 23)°.
And, Angle B is supplementary to Angle A and measures (4x + 46)°.
Since Angle A and B are supplementary.
Hence the sum of both Angles is 180 degrees.
This gives,
∠A + ∠B = 180°
Substitute the given values,
(2x - 23)° + (4x + 46)° = 180°
Combine like terms,
6x + 23 = 180
Subtract 23 on both sides,
6x = 180 - 23
6x = 157
Divide 6 on both sides,
x = 26.17
Therefore, the value of x = 26.17

What do you think the message is from the "1936 Nazi Poster" poster?
Answer:
Become the leader of our nation.
Step-by-step explanation:
Like all Nazi propaganda, the 1936 poster suggests that young Germans are highly capable of becoming leaders of the nation. A young man who must be blond, with teeth and a perfect body. It was unconditional for Nazi propagandists to convince young people to support the goals and policies of the political party.
On the other hand, the leaders of the Nazi youths sought to integrate the children into the national Nazi community and prepare them to serve as soldiers in the armed forces or, later, in the SS.

Answer:
Step-by-step explanation:
The given fractions that we are comparing are expressed as mixed numbers. It means that each is made up of whole numbers and fractions. We would convert each mixed number to improper fraction. By converting to improper fraction, we would multiply the whole number by the denominator and add the product to the numerator. The fraction would be the ratio of the result to the denominator.
Considering 4 2/6, it becomes
(4 × 6) + 2) = 26/6
Considering 3 8/6, it becomes
(3 × 6) + 8)/6 = 26/6

1) Porphyrin is a pigment in blood protoplasm and other body fluids that is significant in body energy and storage. Let x be a random variable that represents the number of milligrams of porphyrin per deciliter of blood. In healthy circles, x is approximately normally distributed with mean μ = 43 and standard deviation σ = 9. Find the following probabilities.
a) x is less than 60
b) x is greater than 16
c) x is between 16 and 60
d) x is more than 60
2)Thickness measurements of ancient prehistoric Native American pot shards discovered in a Hopi village are approximately normally distributed, with a mean of 4.5 millimeters (mm) and a standard deviation of 1.0 mm. For a randomly found shard, find the following probabilities. a) the thickness is less than 3.0 mm
b) the thickness is more than 7.0 mm
c) the thickness is between 3.0 mm and 7.0 mm.
Answer:
1)
a) 0.9706 = 97.06% probability that x is less than 60.
b) 0.9987 = 99.87% probability that x is greater than 16.
c) 0.9693 = 96.93% probability that x is between 16 and 60.
d) 0.0294 = 2.94% probability that x is more than 60.
2)
a) 0.0668 = 6.68% probability that the thickness is less than 3.0 mm.
b) 0.0062 = 0.62% probability that the thickness is more than 7.0 mm
c) 0.9270 = 92.70% probability that the thickness is between 3.0 mm and 7.0 mm.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
1)
We have that [tex]\mu = 43, \sigma = 9[/tex]
a) x is less than 60
This is the pvalue of Z when X = 60.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{60 - 43}{9}[/tex]
[tex]Z = 1.89[/tex]
[tex]Z = 1.89[/tex] has a pvalue of 0.9706
0.9706 = 97.06% probability that x is less than 60.
b) x is greater than 16
This is 1 subtracted by the pvalue of Z when X = 16.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{16 - 43}{9}[/tex]
[tex]Z = -3[/tex]
[tex]Z = -3[/tex] has a pvalue of 0.0013.
1 - 0.0013 = 0.9987
0.9987 = 99.87% probability that x is greater than 16.
c) x is between 16 and 60
This is the pvalue of Z when X = 60 subtracted by the pvalue of Z when X = 16.
From a), Z when X = 60 has a pvalue of 0.9706.
From b), Z when X = 16 has a pvalue of 0.0013
0.9706 - 0.0013 = 0.9693
0.9693 = 96.93% probability that x is between 16 and 60.
d) x is more than 60
This is 1 subtracted by the pvalue of Z when X = 60.
From a), Z when X = 60 has a pvalue of 0.9706.
1 - 0.9706 = 0.0294
0.0294 = 2.94% probability that x is more than 60.
2)
Now [tex]\mu = 4.5, \sigma = 1[/tex]
a) the thickness is less than 3.0 mm
This is the pvalue of Z when X = 3.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{3 - 4.5}{1}[/tex]
[tex]Z = -1.5[/tex]
[tex]Z = -1.5[/tex] has a pvalue of 0.0668
0.0668 = 6.68% probability that the thickness is less than 3.0 mm.
b) the thickness is more than 7.0 mm
This is 1 subtracted by the pvalue of Z when X = 7.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{7 - 4.5}{1}[/tex]
[tex]Z = 2.5[/tex]
[tex]Z = 2.5[/tex] has a pvalue of 0.9938.
1 - 0.9938 = 0.0062
0.0062 = 0.62% probability that the thickness is more than 7.0 mm
c) the thickness is between 3.0 mm and 7.0 mm.
This is the pvalue of Z when X = 7 subtracted by the pvalue of Z when X = 3.
From b), Z when X = 7 has a pvalue of 0.9938.
From a), Z when X = 3 has a pvalue of 0.0668
0.9938 - 0.0668 = 0.9270
0.9270 = 92.70% probability that the thickness is between 3.0 mm and 7.0 mm.
