The ratio of the shadow of the building to the building's height is 34 meters / 204 meters = 1/6.
We can set up the following proportion to find the length of the shadow of the tree:
(shadow of the tree) / (height of the tree) = (shadow of the building) / (height of the building)
Solving for the shadow of the tree, we get:
(shadow of the tree) = (shadow of the building) * (height of the tree) / (height of the building)
Substituting in the values we know, we get:
(shadow of the tree) = 34 meters * 12 meters / 204 meters
Simplifying, we get:
(shadow of the tree) = 8.16 meters
So the shadow of the tree is approximately 8.16 meters long.
Mrs. Walker filled out a bracket for the NCAA National Tournament. Based on her knowledge of college basketball, she has a 0.45 probability of guessing any one game correctly. What is the probability Mrs. Walker will pick all 32 of the first round games correctly? What is the probability Mrs. Walker will pick exactly 10 games correctly in the first round? What is the probability Mrs. Walker will pick exactly 26 games incorrectly in the first round?
Answers
The probability is approximately 0.230 or 23%.
To calculate the probability of Mrs. Walker picking all 32 of the first round games correctly, we need to multiply the probability of her guessing each game correctly. Since each game is independent and she has a 0.45 probability of guessing correctly, the probability of picking all 32 games correctly is:
P(32 games correct) = (0.45)^32 ≈ 0.0000000403
So, the probability is extremely low, approximately 0.0000000403 or 4.03 × 10^-8.
To calculate the probability of Mrs. Walker picking exactly 10 games correctly in the first round, we need to consider the combination of games she can guess correctly. Since there are 32 games and she wants to pick exactly 10 correctly, we can use the binomial probability formula:
P(exactly 10 games correct) = C(32, 10) * (0.45)^10 * (1 - 0.45)^(32-10)
Using the combination formula, C(32, 10) = 32! / (10! * (32-10)!), we can calculate the probability:
So, the probability is approximately 0.025 or 2.5%.
To calculate the probability of Mrs. Walker picking exactly 26 games incorrectly in the first round, we can use the same approach as before:
P(exactly 26 games incorrect) = C(32, 26) * (0.45)^6 * (1 - 0.45)^(32-26)
Using the combination formula, C(32, 26) = 32! / (26! * (32-26)!), we can calculate the probability:
P(exactly 26 games incorrect) ≈ 0.230
So, the probability is approximately 0.230 or 23%.
In summary, the probability of Mrs. Walker picking all 32 games correctly is extremely low (approximately 0.0000000403), the probability of picking exactly 10 games correctly is 2.5%, and the probability of picking exactly 26 games incorrectly is 23%.
These probabilities reflect the likelihood of Mrs. Walker's guesses based on her 0.45 probability of guessing a single game correctly.

a tent maker wishes to support a 11-ft tent wall by attaching cable to the top of it, and then anchoring the cable 7 feet from the base of the tent. how long of a cable is needed?
Answers
A cord of roughly 13.04 feet is demanded to support the 11 ft roof wall and anchor it 7 feet from the base of the roof.
We can use the Pythagorean theorem to break this problem.
Let the length of the cord be represented by the variable c. We know that the height of the roof wall is 11ft and the distance from the base of the roof to where the cord will be anchored is 7ft. We can use these values to form a right triangle, where the length of the cord is the hypotenuse
Using the Pythagorean theorem, we have
c^2 = 7^2 + 11^2
c^2 = 49 + 121
c^2 = 170
Taking the square root of both sides, we get
c = sqrt( 170)
c is roughly 13.04 feet.
thus, a cord of roughly 13.04 feet is demanded to support the 11- ft roof wall and anchor it 7 feet from the base of the roof.

Will someone please help me with this problem!! **It's multiple choice!
Answers
A = (-7,-6)
B = (8,-9)
Find the slope of line AB
m = (y2-y1)/(x2-x1)
m = (-9-(-6))/(8-(-7))
m = (-9+6)/(8+7)
m = -3/15
m = -1/5
The slope of line AB is -1/5.
Flip the fraction and the sign to go from -1/5 to +5/1 = 5. The perpendicular slope is 5.
Let m = 5.
Use the coordinates of point C (2,12) along with the perpendicular slope to get
y - y1 = m(x - x1)
y - 12 = 5(x - 2)
y - 12 = 5x - 10
y = 5x - 10+12
y = 5x + 2
Lastly, convert this to standard form
y = 5x + 2
5x+2 = y
5x+2-y = 0
5x-y = -2
Choice A is the closest match, but the -56 should be -2 instead. It seems like your teacher made a typo somewhere.
Answer:
5x - y = -2.
Step-by-step explanation:
The equation of this altitude line has a slope = -1/m where m is the slope of line AB . It will also pass through the point C.
The slope of line AB = (-9 - (-6)) / (8 - (-7))
= -3/15
= -1/5
So the slope of the required line = -1 / -1/5 = 5.
Using the point C and the point-slope form of a line:
y - y1 = m(x - x1)
y - 12 = 5(x - 2)
y - 5x = -10 + 12
y - 5x = 2
5x - y = -2.

The volume of a cylinder is 54\pi cubic inches and the height is 6 inches. Find the radius.
Answers
Answer:
radius = 3 inches
Step-by-step explanation:
Volume of a circular cylinder is given by the formula
V = π r ² h
where

Given V = 54π and h = 6 we get
54π = π · r² · 6 = 6πr²
r² = 54π/6π
r² = 9
r = √9
r = 3

Three sticks p q and r of the same size are put together so that each one is perpendicular to the other two three longer stick's 's t and u are the placed to make a frame how many tringales will u get and of what type
Answers
Depending on the lengths of the sticks and the resulting shape of the frame, we can have either one or two triangles formed: an equilateral right-angled triangle, an isosceles right-angled triangle, or a combination of an acute-angled triangle and a right-angled triangle.
When three sticks of the same size are put together to form a frame, we can determine the number and types of triangles formed based on the relative lengths of the sticks.
Let's consider the sticks P, Q, and R forming the frame. Since each stick is perpendicular to the other two, we can visualize the frame as a right-angled triangle.
1. If all three sticks are of equal length, then we have an equilateral right-angled triangle. In this case, the frame forms only one triangle.
2. If two sticks are of equal length, and the third stick is shorter, we have an isosceles right-angled triangle. In this case, the frame also forms only one triangle.
3. If all three sticks are of different lengths, we have a scalene right-angled triangle. In this case, the frame forms two triangles: one acute-angled triangle and one right-angled triangle.

suppose we run an experiment where you toss a fair coin 6 times. what is the probability that you will toss exactly 2 heads? a. 0.0156 b. none of these c. 0.2344 d. 0.0938 e. 0.3750
Answers
Answer:
Step-by-step explanation:
Answer for this question is option (c) 0.2344
Approach:
The probability of getting a Head in single toss
x= 1/2
The probability of not getting a Head in single toss
y= 1 - 1/2 = 1/2
Now, using Binomial Theorem, the probability of getting r = 2 heads in total n = 6 tosses
= ⁶C₂ * (1/2)² * (1/2)⁶⁻²
= [ (6!) / (2! * 4!) ] * (1/4) * (1/16)
= [ (6*5*4*3*2*1) / (2*1 * 4*3*2*1) ] * (1/64)
= 15/64
= 0.234374
= 0.2344 (Round off value)
#SPJ4
Given:
A fair coin is tossed 6 times.
To find:
Probability that you will toss exactly 2 heads.
Probability that you will get a head in a single toss is: Q = 1/2
Probability that you will not get a head in a single toss is: R = 1 – 1/2 = 1/2
We use Binomial Theorem to find the probability of getting 2 heads (x) in a total of 6 tosses (n)
Probability = ⁶C₂ x (1/2)² x (1/2)⁶⁻²
Probability = [(6!) / (2! x 4!)] x (1/4) x (1/16)
Probability = [(6 x 5 x 4 x 3 x 2 x 1) / (2 x 1 x 4 x 3 x 2 x 1)] x (1/64)
Probability = 15 / 64
Probability = 0.234374
Probability = 0.2344
Therefore, the probability of getting exactly 2 heads in 6 tosses is 0.2344

Answers
The most common type of observational study is a Survey.
What is an observational study ?A study involving the measurement of variables that are not under the control of the researcher due to a specific logical problem. Experiments involve well-designed studies of the effect of one variable on another. Statistical inference is the process of making inferences about a population based on the results of a sample study. A debate is a formal discussion of a particular topic in a well-organized manner, in which opposing arguments are debated and finally the final argument is voted on. A survey is a data collection technique that investigates the characteristics of a sample of a population.Observe the change in behavior of the independent variable. Don't add prejudice. Use surveys to get information about variables.
CalculationIn the study, the independent variable is observed only for its behavior. Variables naturally exhibit variation. Researchers must not be biased when conducting research. Fundamentally, surveys help us obtain information about social parameters.
Step: 1
An experiment is a well-planned study of any particular cause and effect relationship between variables of interest. A debate is the form of discussion in which a conclusion is to be summarized at last. The statistical inference is a very crucial subject involving the predictions about population parameters based on sample statistics. The survey is the method of collection of information on variables which are not under the control of the experimenter.
The analysis defines various terminologies intermixed with the right answer to the question of interest.
Step: 2
An observational study is mostly conducted in the form of questionnaire. The questionnaire involves question regarding the issue to be studied. The most common type of observational study is a Survey.
Most of the observational studies are carried out in the form of surveys.
