(6) In a triangle, the sides have a ratio of 3:7:10. If the perimeter is 210 feet, what is the length of the longest side in feet? (A) * 10.5 (B) 31.5 (C) (D) 105
Answer:
(D)105 ft
Step-by-step explanation:
In a triangle, the sides have a ratio of 3:7:10. If the perimeter is 210 feet, what is the length of the longest side in feet? (A) * 10.5 (B) 31.5 (C) (D) 105
we divide the perimeter by the sum of the ratios and multiply by the largest ratio and we will have the longest side.
[210 : (3 + 7 + 10)] x 10 = 105 ft (your answer)
Step-by-step explanation:
the ratio tells us into how many units the total amount is split and then distributed among the different parts or members of the ratio.
3:7:10 means there are 3+7+10 = 20 units of length.
210 ft is the total of all lengths.
this is now split into these 20 units.
that means one unit of length for the ratio is
210/20 = 10.5 ft
the longest side is clearly the one with 10 units in the ratio.
so, it has
10×10.5 = 105 ft
a circular hall has a hemispherical roof. the greatest height is equal to the internal diameter .if the capacity of the hall is 43510 m^3 ,then the area of the floor is
This building is basically a cylinder with a hemisphere on top. Let d be the diameter of the hemispherical roof. This is also the height of the entire building as the greatest height is this value (which is located at the center of the building)
The hemisphere itself is r = d/2 meters high, which is the radius of the roof. The cylinder portion's height must be d - r = d - d/2 = 2d/2 - d/2 = d/2 = r meters. So basically the cylinder and the hemisphere both have the same height of r.
At the same time, the cylinder and hemisphere also have the same radius r, or else the roof wouldn't fit on the cylinder.
------------------------------
Volume of cylinder = pi*r^2*h = pi*r^2*r = pi*r^3
Note how I replaced h with r and simplified.
Also,
Volume of hemisphere = (1/2)*(volume of sphere)
Volume of hemisphere = (1/2)*( (4/3)*pi*r^3 )
Volume of hemisphere = (2/3)*pi*r^3
------------------------------
Add the two volume expressions
total volume = (volume of cylinder) + (volume of hemisphere)
total volume = (pi*r^3) + ( (2/3)*pi*r^3 )
total volume = (3/3)pi*r^3 + (2/3)pi*r^3
total volume = (5/3)pi*r^3
------------------------------
Set this equal to 43510 and solve for r
(5/3)pi*r^3 = 43510
pi*r^3 = (3/5)*43510
pi*r^3 = 26106
r^3 = 26106/pi
r = (26106/pi)^(1/3)
r = 20.2549023450428
The building has a radius of approximately 20.2549023450428 meters
------------------------------
We can now compute the area of the circular floor
area = pi*r^2
area = pi*(20.2549023450428)^2
area = 1,288.87316044698
Answer: approximately 1288.87316044698 square metersRound this however you need to
the grades in an exam were normally distributed with a mean of 80 and standard deviation of 4 . what is the probability that a randomly selected student scored between 70 and 84 ? ( round to 4 decimal places)
The probability that a randomly selected student scored between 70 and 84 is 0.8351
Probability
Probability is simply how likely something is to happen.
Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.
given that:
mean = 80
standard deviation = 4
now we need to find the probability of students scored between 70 and 84
P(70<X<84) = P(X<84) - P(X>70)
= P(Z<(84-80)/4)-P(Z>(70-80)/4)
=P(Z<1) - P(Z>-2.5)
= 0.8413-0.0062
= 0.8351
the probability that a randomly selected student scored between 70 and 84 is 0.8351

A number cube that has sides numbered 1 through 6 is rolled 180 times
The probability of landing on any particular side is 1/6, assuming that the cube is fair. Based on the Law of Large Numbers, the more times the cube is rolled, the closer the results will be to the expected probability.
A number cube, commonly known as a die, has six sides numbered from 1 to 6.
When you roll the cube 180 times, each number has an equal probability of showing up, which is 1/6 or approximately 16.67%.
In this scenario, on average, each number (1-6) will appear 30 times (180 rolls divided by 6 sides).
However, due to the random nature of rolling a die, the actual occurrences of each number might vary slightly from the expected average.

Solve for all values of c in simplest form.
43=[c+21]
Answer:
If those are absolute value lines: 22 and -64
Step-by-step explanation:
43 = | c + 21 | is an absolute value equation, meaning it has two answers.
To get the first you keep 43 positive and remove the absolute values and solve normally: 43 = c + 21 -> 43 - 21 = c -> c = 22.
To get the second you make 43 negative and remove the absolute values then solve: -43 = c + 21 -> -43 - 21 = c -> c = -64
43 = 22 + 21 -> 43 = 43
43 = -64 + 21 -> 43 = 43

Let X be normally distributed random variable with mean 10 and variance 25.
a. Calculate P (X >= 2)
b. Plot the histogram of Y = FX(X) with n = 1000, where FX is the distribution function of X. What can you conclude about the distribution of Y? (Hint: compare the histogram of Y
with the histogram of uniform distribution of [0, 1])
To calculate P(X ≥ 2), we need to standardize the variable X. First, we find the standard deviation of X by taking the square root of the variance: σ = √(25) = 5.
Then, we calculate the z-score for the value 2 using the formula z = (X - μ) / σ, where μ is the mean of X. Plugging in the values, we get z = (2 - 10) / 5 = -1.6. We can then look up the probability corresponding to this z-score in the standard normal distribution table or use a calculator. P(X ≥ 2) is equal to 1 minus the probability of X being less than 2, which can be written as P(X ≥ 2) = 1 - P(X < 2). By looking up the z-score of -1.6 in the table, we find that the probability is approximately 0.0548. Therefore, P(X ≥ 2) ≈ 1 - 0.0548 ≈ 0.9452.
To plot the histogram of Y = FX(X), we need to generate random samples from the distribution of X and compute the corresponding values of the distribution function FX. Since X is a normally distributed random variable, we can use a random number generator to generate samples from the normal distribution with mean 10 and variance 25. We then apply the distribution function FX to each sample to obtain the corresponding values of Y. By plotting the histogram of Y with a sample size of n = 1000, we can observe the shape of its distribution. If the histogram of Y closely resembles a uniform distribution on the interval [0, 1], it suggests that Y follows a uniform distribution. Conversely, if the histogram of Y deviates significantly from a uniform distribution, it indicates that Y does not follow a uniform distribution. Comparing the histogram of Y with the histogram of a uniform distribution on [0, 1], we can draw conclusions about the distribution of Y.

a survey of 400 non-fatal accidents showed that 173 involved faulty equipment. find a point estimate for p, the population proportion of accidents that involved faulty equipment
Based on a survey of 400 non-fatal accidents, where 173 involved faulty equipment, the point estimate for the population proportion (p) of accidents that involved faulty equipment is 173/400 = 0.4325.
To calculate the point estimate for the population proportion, we divide the number of accidents involving faulty equipment (173) by the total number of accidents surveyed (400).
This gives us a ratio of 0.4325, which represents the estimated proportion of accidents involving faulty equipment in the population.
A point estimate is a single value that serves as an approximation or best guess for an unknown population parameter.
In this case, the population proportion (p) represents the proportion of all accidents that involved faulty equipment. The point estimate of 0.4325 suggests that approximately 43.25% of non-fatal accidents may involve faulty equipment based on the sample data.
It's important to note that this point estimate is subject to sampling variability and may not perfectly reflect the true population proportion. To obtain a more precise estimate with a measure of uncertainty, one would need to consider confidence intervals or conduct hypothesis testing using statistical methods.
