Answer:
\(\frac{5}{143}\) chance
Step-by-step explanation:
Chance of getting yellow first time: \(\frac{2}{13}\)
Chance of getting green without replacement from yellow: \(\frac{5}{12}\)
Chance of getting red without any replacement: \(\frac{6}{11}\)
\(\frac{2}{13} *\frac{5}{12} *\frac{6}{11} =\frac{60}{1716} =\frac{10}{286} =\frac{5}{143}\)
13. For a given set of data, what does the standard deviation measure?
The difference between the mean and the data point farthest from the mean
The difference between the mean and the data point nearest to the mean
The difference between the mean and the median
None of the above
Source
The standard deviation measures the spread of data points around the mean. It considers all data points, not just the farthest or nearest ones. A higher standard deviation indicates a greater spread.
The standard deviation is a statistical measure that tells us how much the data points in a set vary from the mean. It provides information about the spread or dispersion of the data. To calculate the standard deviation, we take the square root of the variance, which is the average of the squared differences between each data point and the mean.
By considering all data points, the standard deviation provides a comprehensive measure of how spread out the data is. Therefore, the statement "The difference between the mean and the data point farthest from the mean" is incorrect, as the standard deviation does not focus on just one data point.
The statement "The difference between the mean and the data point nearest to the mean" is also incorrect because the standard deviation takes into account the entire data set. The statement "The difference between the mean and the median" is incorrect as well, as the standard deviation is not specifically related to the median.
Hence, the correct answer is "None of the above."

cars a and b leave town at the same time. car a heads due south at rate of 80 km/hr and car b heads due west at a rate of 60 km/hr. how far is the distance between the cars increasing after three hours?
The distance between the two cars after three hours is 300 km
Cars a and b leave town at the same time.
The speed of the car that went to south = 80 km/hour
The total distance traveled in three hours = 80 × 3
= 240 km
The speed of the car that went to the west = 60 km/hour
The total distance traveled in three hours = 60 × 3
= 180 km
The distance between the two car is the hypotenuse of the right triangle
The distance between the two cars after three hours = \(\sqrt{240^2+180^2}\)
= \(\sqrt{57600+32400}\)
= \(\sqrt{90000}\)
= 300 km
Hence, the distance between the two cars after three hours is 300 km

Find the volume and surface area of a square pyramid. Volume of a pyramid: v = 1/3(area of base) x (height) surface area of a pyramid: a = 1/2(perimeter of base) x (slant height) + (area of base) a pyramid has a height of 4. 7 in. And a slant height of 5. 2 in. Its base is a square with sides of 3. 5 in. Find the pyramid's volume and surface area. Volume (to the nearest tenth) = in3 surface area (to the nearest tenth) = in2.
The Volume of the Pyramid=19.19in³
Surface Area of the Pyramid=48.65in²
What is meant by volume?Volume is a unit of measurement for the area occupied in three dimensions. It is widely quantified and measured using SI-derived units, alternative imperial units, or US standard units (such as the gallon, quart, cubic inch). Volume and length (cubed) have a similar meaning.
First, volume was calculated using naturally occurring vessels with a similar shape, and then using standardized containers. Calculating the volume of numerous common three-dimensional forms is made simple by arithmetic formulas. The volumes of increasingly complicated shapes can be calculated using integral calculus.
Given that,
Height of the pyramid =4.7
Pyramid's slant height= 5.2
Base of pyramid is a square with side=3.5
Volume of the pyramid=(1/3)(3.5×3.5)×(4.7)
=19.19 in³
The surface area of a pyramid=((1/2)×(4×3.5)×5.2)+(3.5×3.5)
=18.65in²
Therefore, the volume of the pyramid=19.19 in³

In a recent tennis tournament, women playing singles matches used challenges on 135 calls made by the line judges. Among those challenges, 36 were found to be successful with the call overturned.
a. Construct a 95% confidence interval for the percentage of successful challenges.
b. Compare the results from part (a) to this 95% confidence interval for the percentage of successful challenges made by the men playing singles matches: 23.6%
a) The 95% confidence interval is 18.95% to 34.49%. b) The confidence interval for women (18.95% to 34.49%) does not include the value of 23.6%.
To construct a 95% confidence interval for the percentage of successful challenges made by women playing singles matches, we can use the formula for the confidence interval for a proportion. The formula is:
Confidence Interval = p ± Z * \(\sqrt{p(1-p)/n}\)
Where:
p is the sample proportion (successful challenges / total challenges)
Z is the z-score corresponding to the desired confidence level
n is the sample size
a. Let's calculate the confidence interval for the percentage of successful challenges made by women:
Sample size (n) = 135
Number of successful challenges (x) = 36
Sample proportion (p) = x/n
p = 36/135 ≈ 0.2667
To find the z-score corresponding to a 95% confidence level, we need to calculate the critical value. Since the sample size is large enough (n > 30), we can approximate the critical value using the standard normal distribution.
The z-score corresponding to a 95% confidence level (two-tailed test) is approximately 1.96.
Confidence Interval = 0.2667 ± 1.96 * \(\sqrt{0.2667(1-0.2667)/135}\)
Calculating the confidence interval:
Confidence Interval = 0.2667 ± 1.96 * \(\sqrt{0.2667*0.7333/135}\)
= 0.2667 ± 1.96 * \(\sqrt{0.19511/135}\)
= 0.2667 ± 1.96 * 0.03943
≈ 0.2667 ± 0.07723
The lower bound of the confidence interval is:
0.2667 - 0.07723 ≈ 0.1895
The upper bound of the confidence interval is:
0.2667 + 0.07723 ≈ 0.3449
Therefore, the 95% confidence interval for the percentage of successful challenges made by women is approximately 18.95% to 34.49%.
b. To compare the results with the 95% confidence interval for the percentage of successful challenges made by men (23.6%), we can observe that the confidence interval for women does not overlap with the value for men.
The confidence interval for women (18.95% to 34.49%) does not include the value of 23.6%. This suggests that there may be a significant difference in the percentage of successful challenges made by women compared to men.

Answer:
h = 61.83 feet
Step-by-step explanation:
length of string from Hector to kite = c = 86 feet.
and 4 feet off the ground.
angle A = 42° 15' 30"
req'd: how high is the kite?
angle A = 42° + 15' (1° / 60') + 30"(1° / 3600'')
angle A = 42.26
to get the side a (height of kite) 4 feet above ground: use Sin(A) = opp / hyp
Sin(A) = a / c
Sin(42.26) = a / 86
a = Sin(42.26) * 86

Step-by-step explanation:
Just by doing the math.
Consider the statement
"An angle with a measure of 88° is an acute angle."
Classify and determine whether each conditional form of this statement is true or false,
• If an angle is an acute angle, then its measure is 88°
Geometry
Answer:
The conditional form of this statement is false.
Step-by-step explanation:
Angles that are less than 90°, also known as right angle, are known as acute angles.
So, any angle that has a measure between 0° and 90° are known as acute angles.
The statement provided is:
"An angle with a measure of 88° is an acute angle."
The conditional form of this statement provided is:
"If an angle is an acute angle, then its measure is 88°."
This statement is false.
This is because an acute angle can measure between 0° and 90°.
It is not necessary that the measure of an acute angle is 88°.
Thus, the conditional form of this statement is false.
Answer:
this angle would be acute
Step-by-step explanation:
why? because its less than 90 in which means it acute.
Suppose that X has a hypergeometric distribution with N = 100, n = 4, and K = 20. Determine the following: a. P(X = 1) b. P(X = 6) c. P(X = 4) d.
The probabilities for the hypergeometric distribution with the given parameters are:
a. P(X = 1) ≈ 0.000407
b. P(X = 6) = 0
c. P(X = 4) ≈ 0.098117
d. P(X = 0) ≈ 1.97e-05
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty.
To determine the probabilities for the hypergeometric distribution with the given parameters, we can use the following formula:
P(X = k) = (choose(K, k) * choose(N-K, n-k)) / choose(N, n)
where "choose(a, b)" represents the binomial coefficient, calculated as a! / (b! * (a - b)!)
Let's calculate the probabilities:
a. P(X = 1):
P(X = 1) = (choose(20, 1) * choose(100-20, 4-1)) / choose(100, 4)
= (20 * 80) / 3921225
≈ 0.000407
b. P(X = 6):
P(X = 6) = (choose(20, 6) * choose(100-20, 4-6)) / choose(100, 4)
= (38760 * 0) / 3921225
= 0
c. P(X = 4):
P(X = 4) = (choose(20, 4) * choose(100-20, 4-4)) / choose(100, 4)
= (4845 * 80) / 3921225
≈ 0.098117
d. P(X = 0):
P(X = 0) = (choose(20, 0) * choose(100-20, 4-0)) / choose(100, 4)
= (1 * 77) / 3921225
≈ 1.97e-05
Therefore:
a. P(X = 1) ≈ 0.000407
b. P(X = 6) = 0
c. P(X = 4) ≈ 0.098117

Substitute:
\(= (8 - 4x - x^3) + (x^2 + 7x - 9)\)
Rewrite:
\(= (-x^3) + (x^2) + (7x - 4x) + (8 - 9)\)
Combine like terms:
\(= -x^3 + x^2 +3x -1\)
In conclusion:
\(f(x) + g(x) = -x^3 + x^2 +3x -1\)
