Step-by-step explanation:

The total amount spent when the 10 items are bought is $97.17.

The final temperature given the increase in temperature and the decrease in temperature is 18 degrees.

In order to determine if your friend has enough money to buy all the items, the total cost of the items have to be determined. The total cost is the sum of all the items bought.

here, we have,

Total cost = total cost of the first three items + total cost of the second three + total cost of the last three

Total cost = (3 x 15.99) + (3 x 10.40) + (4 x 4.50)

Total cost = $47.97 + $31.20 +18

Total cost = $97.17

An increase in temperature would be represented with a positive number. While, a decrease in temperature would be represented with a negative number. The final temperature can be determined by adding the temperature increase and decease together.

Final temperature = increase in temperature - decrease in temperature

Final temperature = 32 - 14 = 18 degrees

Step-by-step explanation:

The probability that a randomly selected score from this normal distribution is less than x = 76 is 0.6915

To find the probability that a randomly selected score from a normal distribution with mean µ = 70 and standard deviation σ = 12 is less than x = 76,

we need to use the standard normal distribution and calculate the z-score corresponding to x = 76, and then look up the corresponding area under the standard normal curve using a standard normal distribution table.

The z-score is calculated as:

z = (x - µ) / σ

z = (76 - 70) / 12

z = 0.5

By using a standard normal distribution table, we can find the area under the curve to the left of z = 0.5, which is 0.6915.

Therefore, the probability that a randomly selected score from this normal distribution is less than x = 76 is 0.6915 or approximately 69.15%.

Therefore, the value of the car after three years is approximately $9,484.

Percent is a term used to represent a fraction of 100. It is denoted by the symbol "%". Percentages are commonly used to express proportions, ratios or fractions in terms of parts per hundred. The word "percent" comes from the Latin phrase "per centum," which means "by the hundred." Percentages are commonly used in everyday life, such as in calculating taxes, discounts, interest rates, and in comparing statistics, among others.

Here,

The exponential decay model for the value of the car after ⁿ years can be written as:

v = 22500 * (0.75)ⁿ

where 22500 is the initial value of the car, and (0.75)ⁿ represents the value after ⁿ years with a 25% annual decrease.

To find the value of the car after three years, we can substitute n = 3 into the equation:

The probability of at least one appearance in a 21-alternate period is 0.969803

(a) The appearance  rate is 10 passengers nanosecond , so the anticipated number of advents  in nanosecond is also 10. The probability of no advents  in one minute is given by the Poisson distribution with parameter lambda = 10:

P(X = 0) = [tex]e^{(-lambda)}[/tex] [tex]lambda^{0}[/tex] / 0! =  [tex]e^{(-10)}[/tex]* [tex]10^{0}[/tex] / 1! = 0.000045 (rounded to 6 decimal places)

Therefore, the probability of no arrivals in one-minute period is 0.000045.

(b) To compute the probability that three or fewer passengers arrive in one-minute period, we can use the cumulative distribution function (CDF) of the Poisson distribution:

P(X <= 3) = sum from i=0 to 3 of P(X = i)

= P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)

= [tex]e^{-10}[/tex] *[tex]10^{0}[/tex] / 0! + [tex]e^{(-10)}[/tex] * [tex]10^{1}[/tex]/ 1! + [tex]e^{(-10)}[/tex] * [tex]10^{2}[/tex] / 2! + [tex]e^{(-10) }[/tex]* [tex]10^{3}[/tex]/ 3!

= 0.010336 (rounded to 6 decimal places)

Therefore, the probability that three or fewer passengers arrive in one-minute period is 0.010336.

(c) The arrival rate is 10 passengers per minute, which is equivalent to 10/60 = 1/6 passengers per second. Therefore, the expected number of arrivals in a 21-second period is (1/6) * 21 = 3.5 passengers. The probability of no arrivals in a 21-second period is given by the Poisson distribution with parameter lambda = 3.5:

P(X = 0) = [tex]e^{(-lambda)}[/tex] * l[tex]lambda^{0}[/tex] / 0! = [tex]e^{(-3.5)}[/tex] * [tex]3.5^{0}[/tex]/ 1! = 0.030197 (rounded to 6 decimal places)

Therefore, the probability of no arrivals in a 21-second period is 0.030197.

(d) The probability of at least one arrival in a 21-second period is equal to 1 minus the probability of no arrivals:

P(at least one arrival) = 1 - P(no arrivals)

Answer:

Step-by-step explanation:

Volume of a cone = 1/3  pi  r^2 h

      4125 pi             = 1/3 pi r^2 h

                       4125  = 1/3 r^2 h  <===if diameter =30  then radius = 15 units

                         4125 = 1/3 (15)^2 h

                            4125 / (1/3 * 15^2) = h = 55 units

Take into consideration the solid that results from rotating the area enclosed by the provided curves about the x-axis. y = 2/7 x^2, y = 9/7 - x^2 . the volume of the solid is approximately 1.412 cubic units.

To find the volume of the solid obtained by rotating the region bounded by the curves y = 2/7 [tex]x^{2}[/tex] and y = 9/7 - [tex]x^{2}[/tex] about the x-axis, we can use the method of disks or washers.

First, we need to find the limits of integration. The curves intersect when:

2/7[tex]x^{2}[/tex] = 9/7 - [tex]x^{2}[/tex]

Multiplying both sides by 7, we get:

2[tex]x^{2}[/tex] = 9 - 7[tex]x^{2}[/tex]

9[tex]x^{2}[/tex] = 9

[tex]x^{2}[/tex] = 1

x = ±1

Therefore, the limits of integration are x = -1 and x = 1.

Next, we need to express the curves in terms of y. Solving for x in each equation, we get:

x = ±√(7/2 y)

x = ±√(9/7 - y)

Using the method of disks, we can find the volume of the solid by integrating the areas of circular disks with radius y from y = 0 to y = 9/7.

The radius of each disk is given by the difference between the upper and lower curves evaluated at y:

r = √(9/7 - y) - √(7/2 y)

The area of each disk is given by:

A = π[tex]r^{2}[/tex]

Substituting for r, we get:

A = π [√(9/7 - y) - √(7/2 y)]

Expanding and simplifying, we get:

A = π [9/7 - y + 7/2 y - 2√(9/7 y)]

A = π [9/7 + 3/2 y - 2√(9/7 y)]

Integrating with respect to y, we get:

V = ∫[0, 9/7] π [9/7 + 3/2 y - 2√(9/7 y)] dy

V = π [(9/7) y + (3/4) - (4/9) [tex]9/7^{3/2}[/tex] [tex]y^{3/2}[/tex]] [0, 9/7]

V = π [81/28 - (64/81)  [tex]9/7^{3/2}[/tex]]

V ≈ 1.412

The percentage of full marks was obtained by D is (d) 60%.

What is percentage  ?

Let's start by using the given information to find out how many marks B, C, and D got in the exam.

We know that A got 10% less than B, so if A got 360 marks, then B got 10% more than that, which is:

B = 360 + 10% of 360

= 360 + 36

= 396

We also know that B got 25% more than C, so if B got 396 marks, then C got 25% less than that, which is:

C = 396 - 25% of 396

= 396 - 99

= 297

Finally, we know that C got 20% less than D, so if C got 297 marks, then D got 20% more than that, which is:

D = 297 + 20% of 297

= 297 + 59.4

= 356.4

So D got 356.4 marks out of 500. To find out what percentage of full marks D obtained, we can use the formula:

A triangle can be classified as either right, obtuse, or acute depending on the measure of its angles. Right triangles have one right angle, obtuse triangles have one obtuse angle, and acute triangles have three acute angles.

To find the volume of a triangular prism, you need to calculate the area of the triangular base and then multiply it by the height of the prism. First, calculate the area of the base by finding the length of the triangle's sides and then using the Heron's Formula. Then, multiply the area of the base with the height of the prism to get the volume of the triangular prism. For example, if the length of the sides of the triangle is 3, 4 and 5, then the area of the base is 6 and the height of the prism is 8, then the volume of the prism is 48.

According to Pythagoras theorem.

c² = a²+b²

(51)² = (24)²+b²

2601 = 576+b²

2601-576 = b²

2,025 = b²

√2025 = √b²

b = 45
