The elevation gain of Mount Everest is 15,028 feet, a very impressive feat considering it is the highest elevation gain of any mountain in the world.

The difference between the height at the base of Mount Everest, which is 14,000 feet and the summit, which is 29,028 feet is 15,028 feet. This is also known as the elevation gain. It can be calculated using the following formula:

Elevation Gain = Summit Height - Base Height

So in this case, Elevation Gain = 29,028 ft - 14,000 ft

Which gives us: Elevation Gain = 15,028 ft

The elevation gain of Mount Everest is 15,028 feet, a very impressive feat considering it is the highest elevation gain of any mountain in the world.

a. 1/4 of the accidents in May were serious.

b. 1/3 of the accidents in June were serious.

c. June had a higher proportion of serious accidents than May.

A fraction is represented as a numerical indication of a part of a whole that represents a rational numeral.

a. To find the fraction of accidents in May that were serious, we divide the number of serious accidents by the total number of accidents:

Fraction of serious accidents in May = 3/12

Simplifying the fraction in the simplest form as:

3/12 = (3 ÷ 3) / (12 ÷ 3) = 1/4

Therefore, 1/4 of the accidents in May were serious.

b. To find the proportion of accidents in June that were serious, we divide the number of serious accidents by the total number of accidents:

The proportion of serious accidents in June = 5/15

Simplifying the fraction in the simplest form as:

5/15 = (5 ÷ 5) / (15 ÷ 5) = 1/3

Therefore, 1/3 of the accidents in June were serious.

c. The proportion of serious accidents in May and June, we can compare the fractions we obtained in parts (a) and (b).

The mass of the fifth man is 153 kg.

The mean mass of five men is 76 kg.

The masses of four of the men are 72 kg, 74 kg, and 81 kg.

To solve this problem, we need to apply the concept of the mean of a set of data.

The mean is the average of all the values in a set of data.

It is calculated by adding up all the values and dividing by the total number of values in the set.

To find the mass of the fifth man, we need to use the mean of the entire set and the masses of the four men that are already given.

The formula to find the mean of a set of data is:

\(Mean = \frac{(sum of all the values)}{(total number of values)}\)

Let x be the mass of the fifth man.

Then we can write an equation using the given information:

\(Mean = \frac{(72 + 74 + 81 + x)}{5}\)

Substitute the given mean of 76 kg into the equation and solve for x:

\(76 = \frac{(72 + 74 + 81 + x)}{576 × 5} = 227 + x\)

Multiply both sides by 5:

\(380 = 227 + x\)

Subtract 227 from both sides:

\(153 = x\)

Therefore, the mass of the fifth man is 153 kg.

Step-by-step explanation:

The probability that a randomly chosen test-taker will score between 470 and 530 is 0.2358 (or 23.58% when expressed as a percentage).

To solve this problem, we need to use the standard normal distribution formula:
Z = (X - μ) / σ
where Z is the standard score (z-score) of a given value X, μ is the mean, and σ is the standard deviation.
First, we need to convert the given values of 470 and 530 to z-scores:
Z1 = (470 - 500) / 100 = -0.3
Z2 = (530 - 500) / 100 = 0.3
Next, we need to find the probability that a randomly chosen test-taker will score between these two z-scores.

We can use a standard normal distribution table or a calculator to find the area under the curve between -0.3 and 0.3.
Using a calculator or an online tool, we find that the area under the curve between -0.3 and 0.3 is approximately 0.2358.

using the cosine ratio in the right triangle

cos x = \(\frac{adjacent}{hypotenuse}\) = \(\frac{AC}{AB}\) = \(\frac{7}{23}\) , then

Answer:

n = 0 or 10

Step-by-step explanation:

From the question,

Equation of the circle = (x-1)²+(y-5)² = 50 ............... Equation 1

Coordinate of the circle = (6,n)

From the question

x = 6, y = n

Substitute the value of x and y into equation 1

(6-1)²+(n-5)² = 50

5²+(n-5)² = 50

25+(n-5)² = 50

(n-5)² = 50-25

(n-5)² = 25.

Solving for n

n-5 = √(25

n-5 = ±5

Either,

n-5 = -5

n = -5+5

n = 0

or

n-5 = +5

n = 5+5

n = 10

Answer:

n = 3.16

Step-by-step explanation:

Since the point (6, n) lies on the circle then the coordinates of the point make the equation true.

Substitute x = 6 and y = n into the equation

(6 - 1)² + (n - 5)² = 50, that is, expanding using FOIL

5² + n² - 10n + 25= 50 by simplifying

25 + n² - 10n = 50 ( subtracting 50 from both sides and rearrange )

n² - 10n = 0 ← in standard form

n²=10

n = √10

The values of n is 3.16

The Braille system uses two vertical columns of three dots each to represent characters. There are 8 possible combinations for each column, giving a total of 64 distinct Braille characters.

The Braille system of representing characters was developed by Louis Braille in the early nineteenth century. This system is used by blind people and consists of raised dots that represent characters. The positions for the dots are selected from two vertical columns of three dots each. At least one raised dot must be present to represent a character.

To determine the number of distinct Braille characters possible, we need to consider the number of ways we can arrange the dots in the two vertical columns. Each column has three dots, and we need to choose which of these three dots to raise to represent a character. This gives us a total of 2^3 = 8 possible combinations for each column.

Since we have two columns, we can multiply the number of possible combinations for each column to get the total number of distinct Braille characters. This gives us 8 x 8 = 64 possible characters.

If there are 50 coins in all. Of the​ coins, 12​% are pennies and ​32% are dimes there are 2 more nickels than pennies then the bag contains $5.55 in total.

Let P be the number of pennies in the bag.

Let N be the number of nickels in the bag.

Let D be the number of dimes in the bag.

Let Q be the number of quarters in the bag.

From the problem, we know that:

P + N + D + Q = 50 (because there are 50 coins in total)

P = 0.12(50) = 6 (because 12% of the coins are pennies)

D = 0.32(50) = 16 (because 32% of the coins are dimes)

N = P + 2 (because there are 2 more nickels than pennies)

Substituting the values we know into the equation for the total number of coins, we get:

6 + (P + 2) + 16 + Q = 50

Simplifying this equation, we get:

P + Q = 26

Substituting the value we know for pennies P, we get:

6 + Q = 26

Q = 20

P = 6

Substituting the values we know for P and Q into the equation for the total value of the coins in the bag, we get:

0.01(6) + 0.05(P + 2) + 0.1(16) + 0.25(20) = $5.55

Binomial probability distribution for the given set of data is

\(100C_x (0.20)^x (0.80)^{100-x}\)

What is binomial probability distribution?

"Binomial probability distribution is the representation of  a probability with only two outcomes success and failure under given number of trials."

Binomial probability distribution is given by

\(nC_x p^x q^{n-x}\)

n= number of experiments

x = 0, 1, 2, 3,.......

p = probability of success

q = probability of failure

According to the given question

Number of trials  'n' = 100

Probability of success 'p' = (20 / 100)

                                          = 0.20

Probability of failure 'q' = 1 - p

                                       = 1 - (20/100)

                                       =  (80 / 100)

Substitute the value in the formula we get

Required probability = \(100C_x (0.20)^x (0.80)^{100-x}\)

Example:

Tossing a coin 6 times getting exactly two heads.

Number of trials 'n' = 6

Number of heads 'x' =2

Only two possible outcomes head or tail

Probability of getting head 'p' = 1 / 2

Probability of not getting head 'q' = 1 /2

Required probability = \(6C_2\) (1/2)²(1/2) ⁶⁻²

                                  = \(6C_2\\\) (1/2)⁶

Hence, binomial probability distribution for the given set of data is

\(100C_x (0.20)^x (0.80)^{100-x}\)

In a binomial experiment with probability of success and trials is conducted, the probability of one trial is independent of another.

How to find the number of success in a binomial distribution?

The likelihood of success is constant from trial to trial, and subsequent trials are independent. A binomial expression, which derives from counting successes across a series of trials, has just two possible outcomes on each trial.

One of the two outcomes, known as success or failure, arises from every try. From trial to trial, the chance of success, indicated by the symbol p, stays constant. There are n independent trials. In other words, the probability of one trial do not influence those of the others.

Therefore, in a binomial experiment with probability of success and trials is conducted, the probability of onetrial is independent of another.
