What is a right rectangular pyramid?A right rectangular pyramid is a pyramid, with four slant sides, and a rectangular base, such that all the sides are congruent and the vertex is atop of the midpoint of the base rectangle.
Suppose the base of the pyramid has length = l units, and width = w units.
Suppose that the height of the pyramid is of h units, then:
[tex]v = \dfrac{l \times w \times h}{3} \: \rm unit^3[/tex]
is the volume of that pyramid.
The base is a rectangle with length = L units, and width = W units, so its area is:
[tex]b = l \times w\: \rm unit^2[/tex]
Given that;
Altitude of pyramid= 10
Each side base of pyramid= 6
Now,
So using pythagorean theorem,
x2=y2+(10)2....1
with y half of the length of the diagonal of the base.
2y=length of the diagnol
and (2y)2 = 72
4y2=72
y = 3√2.
So substitute y in eq1 and get x
( 3√2)2+(10)2=(x)2
(x)2=118
x=10.86.
x≈10.9
Therefore, the side of right square pyramid will be 10.9.

convert the following measurement
Answer:
3.4 x 10⁻² kg · m²/s²
Step-by-step explanation:
[tex]3.4\times \:10^5=340000[/tex]
The numerator is in g.cm² and the denominator is the same s²
So we only need to convert the numerator from g.cm² to kg.m²
1 kg = 1000 grams = 10³ grams
1 gm = 1/10³ kg
1 gm = 10⁻³ kg
1 m = 100 cm = 10² cm
1 m² = 100² cm² = (10²)² = 10⁴ cm²
Or 1 cm² = 1/10⁴ cm² = 10⁻⁴ cm²
Therefore to convert g · cm² to kg · m² we multiply by
(10⁻³) · (10⁻⁴) = 10⁻⁷
Therefore 3.4 x 10⁵ g · cm² = 3.4 x 10⁵ x 10⁻⁷ kg · m²
= 3.4 x 10⁻² kg · m²/s²

According to the posed question, the rectangular prism's surface area would be 90 cm2.
What is a Rectangular Prism's Surface Area?
The total surface area of a rectangular prism's rectangular faces is alluded to as the prism's surface area. There are two distinct types of it: lateral surface area and total surface area. In contradiction to the lateral surface area, which only includes the lateral faces and omit the base areas, the total surface area of a rectangular prism refers to the area among all six faces.
Given, W = 3 cm, L = 6 cm, and H = 3 cm
surface area = 2 (WL + LH + HW)
= 2 (18 + 18 + 9)
= 2× 45 = 90 cm².

what is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line
Answer:
[tex]\frac{8}{5}[/tex] and - [tex]\frac{5}{8}[/tex]
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
8x - 5y = 1 ( subtract 8x from both sides )
- 5y = - 8x + 1 ( divide through by - 5 )
y = [tex]\frac{8}{5}[/tex] x - [tex]\frac{1}{5}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{8}{5}[/tex]

A system is made up of two subsystems, A and B, connected in-series (i.e., the system fails if either subsystem fails). Subsystem A is made up of components 1 and 2, connected in series. Component 1 fails according to a Poisson process with rate 0.2 per month, whereas component 2 fails as a Poisson process with rate 0.08 per month. Subsystem B is made up of a single component 3, which is subject to repeated disruptions. The disruptions arrive as a Poisson. process with rate 1.2 per month but only 20% of them cause the failure of component 3.
a) Find the probability that the system will fail during a 3-month period.
b) Find the probability that there will be no more than two failures of the system during a 6-month period.
c) Find the probability that the next system failure will occur within a year.
Answer: a) The probability that the system will fail during a 3-month period can be calculated as the sum of the probabilities of subsystem A and subsystem B failing, since the system fails if either one fails. The probability of subsystem A failing in 3 months is given by P(A) = 1 - e^(-0.2 * 3) * (1 + 0.2 * 3 + (0.2 * 3)^2 / 2!) = 0.0664. The probability of subsystem B failing in 3 months is given by P(B) = 1 - e^(-1.2 * 3) * (1 + 0.2 * 3 + (0.2 * 3)^2 / 2!) = 0.36. Therefore, the probability that the system will fail in 3 months is P(system) = P(A) + P(B) = 0.0664 + 0.36 = 0.4264.
b) To find the probability that there will be no more than two failures of the system during a 6-month period, we need to use the cumulative distribution function (CDF) of the Poisson distribution. Let X be the number of failures of the system in 6 months. The CDF is given by F(x) = P(X <= x) = 1 - P(X > x), where P(X > x) is the probability that there will be more than x failures. Therefore, the probability that there will be no more than two failures of the system during a 6-month period is given by F(2) = 1 - P(X > 2). We can use the formula for the Poisson distribution to find P(X > 2), which is P(X > 2) = e^(-6 * (P(A) + P(B))) * ((6 * (P(A) + P(B)))^3 / 3! + (6 * (P(A) + P(B)))^2 / 2! + 6 * (P(A) + P(B)) / 1! + 1). Plugging in the values for P(A) and P(B) from part (a), we get F(2) = 1 - e^(-6 * 0.4264) * ((6 * 0.4264)^3 / 3! + (6 * 0.4264)^2 / 2! + 6 * 0.4264 / 1! + 1) = 1 - 0.2079 = 0.7921.
c) To find the probability that the next system failure will occur within a year, we need to find the cumulative distribution function (CDF) of the time between failures, which is the sum of the time between failures of subsystem A and subsystem B. Let X be the time between failures of subsystem A, which follows an exponential distribution with rate 0.2 per month. Let Y be the time between failures of subsystem B, which also follows an exponential distribution with rate 1.2 * 0.2 = 0.24 per month. Then the CDF of the time between failures is given by F(t) = P(X + Y <= t) = 1 - P(X + Y > t0.2 * 12) * e^(-0.24 * 12) = 1 - 0.17 = 0.83. Therefore, the probability that the next system failure will occur within a year is 0.83.

the average rent of one bedroom apartment in brooklyn is 2700 in 2021,if rent will increase 2.5% in 2022 and 2.5% in 2023.what would be the average rent in 2023?
The average rent of a one-bedroom apartment in Brooklyn is estimated to be $2,836.69 in 2023 after the 2.5% increase in both 2022 and 2023
What is the percentage increase?
Percentage increase is a measure of how much a value or quantity has increased relative to its original value, expressed as a percentage.
To calculate the percentage increase, you can use the following formula:
Percentage increase = (New value - Old value) / Old value x 100%
If the average rent of a one-bedroom apartment in Brooklyn is $2,700 in 2021, and it increases by 2.5% in both 2022 and 2023, we can calculate the average rent in 2023 as follows:
Calculate the increase in rent due to the 2.5% increase in 2022:
2.5% of $2,700 = 0.025 x $2,700 = $67.50
The new rent in 2022 will be $2,700 + $67.50 = $2,767.50
Calculate the increase in rent due to the 2.5% increase in 2023:
2.5% of $2,767.50 = 0.025 x $2,767.50 = $69.19
The new rent in 2023 will be $2,767.50 + $69.19 = $2,836.69
Therefore, the average rent of a one-bedroom apartment in Brooklyn is estimated to be $2,836.69 in 2023 after the 2.5% increase in both 2022 and 2023.

The drag force due to air resistance is 11 N acting backwards against Shaun. What is Shaun's acceleration? 30° 4.64 m/s2 down the slope
Previous question
If the drag force due to air resistance is 11 N acting backwards against Shaun. Shaun's acceleration is 4.64 m/s^2 down the slope.
To find Shaun's acceleration, we need to calculate the net force acting on him and his skateboard. The net force is the vector sum of all the forces acting on the object. We can use Newton's second law of motion, which states that the net force acting on an object is equal to the product of its mass and its acceleration:
Net force = mass × acceleration
Let's break down the forces acting on Shaun and his skateboard:
The force of gravity, which acts vertically downwards with a magnitude of mg, where m is the total mass of Shaun and his skateboard and g is the acceleration due to gravity (9.8 m/s^2).
F₁ = m * g * sin(30°) = 75 kg * 9.8 m/s^2 * sin(30°) = 367.5 N
The force due to rolling friction between the skateboard wheels and the concrete, which acts backward against the skateboard.
F₂ = 9 N (given)
The drag force due to air resistance, which acts backward against Shaun.
F₃ = 11 N (given)
Now, let's add up the forces to get the net force:
Net force = F₁ - F₂ - F₃
= 367.5 N - 9 N - 11 N
= 347.5 N
Using Newton's second law of motion, we can now calculate Shaun's acceleration:
acceleration = Net force / mass
= 347.5 N / 75 kg
= 4.64 m/s^2 (down the slope)

Binomial distribution calculation
If n=5 and p=0.7, find P(x=4)
Give at least 4 decimal places.
The binomial distribution P( x = 4 ) if n = 5 and p = 0.7 is 0.3602.
What is the binomial distribution?Binomial probability distribution determines the probability of a discrete random variable.
Given that;
n = 5p = 0.7p( x = 4 )Using the formula, probability mass function;
P( X = x ) = ⁿCₓPˣ( 1 - P )ⁿ⁻ˣ
P( X = x ) = ⁵Cₓ × 0.7ˣ × ( 1 - 0.7 )⁵⁻ˣ
Now for P( x = 4 )
P( X = 4 ) = ⁵C₄ × 0.7⁴ × ( 1 - 0.7 )⁵⁻⁴
P( X = 4 ) = ⁵C₄ × 0.7⁴ × ( 1 - 0.7 )
P( X = 4 ) = 5 × 0.2401 × 0.3
P( X = 4 ) = 0.3602
Therefore, the value of P( x = 4 ) is 0.3602.
