A ramp 24 ft long rises to a platform that is 20 ft off the ground. find x , the angle of elevation of the ramp. round your answer to the nearest tenth of a degree.
Final answer:
To determine the angle of elevation x, we use the sine function with the opposite side (20 ft) and the hypotenuse (24 ft) to get sin(x) = 20/24, and by taking the arcsin of the result, we find that x ≈ 56.4° when rounded to the nearest tenth of a degree.
Explanation:
To find x, the angle of elevation of the ramp, we can use trigonometric functions. Since we have the length of the ramp (hypotenuse) and the height of the platform (opposite side) in a right-angled triangle, we can use the sine function, which is defined as the ratio of the opposite side to the hypotenuse.
Using the sine function: sin(x) = opposite/hypotenuse = 20/24.
We first calculate the ratio: sin(x) = 20/24 = 0.8333.
To find the angle x, we take the inverse sine (also known as arcsine) of the ratio: x = arcsin(0.8333).
Using a calculator set to degree mode, we find that x ≈ 56.4° when we round to the nearest tenth of a degree.
How to go from sum of products to product of sums?
Multiplication gives us distribution over the products, so
(a′+b+d′) (a′+b+c′+f′) = a′ (a′+b+c′+f′) + b (a′+b+c′+f′) + d′ (a′+b+c′+f′)
And then you can then distribute again each of the factors on the right.
Then you should simplify in any given number of ways. To take as an example, you have a′b and ba′, and since a′b + a′b = a′b + a′b = a′b, you can just drop one of them. Since bb = b, you can rewrite bb as b and etc.
So in the end part we should arrive at a sum of products. Then you can just invert. For example, if at the end you had:
p′ = a′b + bc′ + d′f ′+ a′f′
Then we would have
p = p′′ = (a′b + bc′ + d′f′ + a′f′)′ = (a′b)′⋅(bc′)′⋅(d′f′)′⋅(a′f′)′
Then applying De Morgan's laws to each of the factors, e.g., (a′b)′ = a+b′, so we would have
p = (a+b′)⋅(b′+c)⋅(d+f)⋅(a+f)
which is a product of sums.

Gitta is asked to find the probability of getting all heads on 3 coin tosses. This is a compound event. True or False?
Answer with explanation:
Event Joining by two or more Simple events is called Compound Event.
When you throw a coin once, getting either Head or Tail is a Simple event.
And , when you throw a coin and dice together, getting , Head and 1 , is a Compound event.Because here we joined two simple events, one is Throwing of a coin and another one is throwing a dice.
When you toss a coin thrice, it is combination of three simple events, that is tossing of coin three times .So total possible outcome
[tex]=2^3\\\\=8[/tex]
Which can be written as: {(HHH),(HHT),(HTH),(THH),(HTT),(THT),(TTH),(TTT)}
Probability of getting all heads on 3 coin tosses
= Sum of three simple events
[tex]=\frac{HHH}{\text{Total 8 Outcome}}\\\\=\frac{1}{8}[/tex]
or
Probability of Getting head in all three throws
[tex]=\frac{1}{2}\times \frac{1}{2} \times \frac{1}{2}\\\\=\frac{1}{8}[/tex]
Yes, this is a Compound event.
How to write 100000 in scientific notation?
Answer:
100000 in scientific notation:[tex]100,000=1.0\times 10^{5}m/s[/tex]
Step-by-step explanation:
Scientific notation is defined as the notation in which a number is expressed in the decimal form. This means that the number is always written in the power of 10 form. The numerical digit lies between 0.1.... to 9.9.....
If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.
We are given: 100,000
Converting this into scientific notation, we get:
[tex]\Rightarrow 100,000=1.0\times 10^{5}m/s[/tex]
As, the decimal point is shifting to left side, thus the power of 5 is positive.

A board is 27 inches long. How long is the board in centimeters? Use the following conversion: 1 inch is 2.54 centimeters.
1 inch = 2.54 cm
so multiply 27 by 2.54
27 x 2.54 = 68.58 cm long
To convert 27 inches to centimeters, multiply 27 by the conversion factor of 2.54 cm per inch, resulting in 68.58 centimeters.
The student has asked how long a board that is 27 inches long is in centimeters, given the conversion factor that 1 inch is equal to 2.54 centimeters. To convert inches to centimeters, you multiply the length in inches by the conversion factor. In this case, you would multiply 27 inches by 2.54 to find the length in centimeters.
Here is the calculation:
27 inches x 2.54 cm/inch = 68.58 centimeters.
Therefore, a board that is 27 inches long is 68.58 centimeters long.

A building manager installs sensors to see how often people turn off the lights when they leave a room. After a month, the manager has a sample size of 400, a sample mean of 47%, and a sample standard deviation of 4%. What is the confidence level for a confidence interval of 46.6% to 47.4%?
A. 68%
B. 85%
C. 99.7%
D. 95%
The answer is C.
The figures in your problem are inconsistent with
the data.
The sample std deviation is not and cannot be .04 (4%).
the sample std dev is sqrt[(.47)(1-.47)/400]=.02495.
The margin of error from your CI is .474 -.47= .004 (very
small).
This would represent .02495/.004= 6.24 std dev. from
expected, which would have a very
high level of confidence (99.97.. %). Something is likely
wrong with the figures in your problem.
Answer: 95%

Is the data set “heights of the women in the U.S. Congress” quantitative or qualitative? If it is quantitative, is it discrete or continuous?
Answer with explanation:
The “heights of the women in the U.S. Congress” is Quantitative,because height of person does not represent Quality, it shows "Quantity".It means it has Magnitude.
We can find mean , median and mode of women in Congress.
So, Height of women in US congress is Quantitative.
As, different Women have different Heights, that is any rational number , so The Height of different women will be a discrete data set.For, example, height of different women can be={167 cm, 187.6, 176.6,165.5,.....}
