Step-by-step explanation:
Volume of the shaded portion = volume of triangular pyramid - volume of cone

Where,
A = 15*10 = 150 units²
r = ½(9) = 4.5 units
h = 12
Plug in the values
Volume of the shaded portion = ⅓*150*12 - ⅓*π*4.5²*12

What is the volume of the shape below
The volume of the given figure is 1176 cubic cm.
The value of the figure is calculated by multiplying all three side areas. Volume is a measure of the amount of space that an object or a substance occupies. It is typically expressed in cubic units such as cubic meters (m³), cubic centimetres (cm³), or cubic feet (ft³).
The volume of the figure is calculated as,
Volume = 2 ( 15 x 6 + 20 x 6 + 20 x 18 )
Volume = 1176 Cubic cm
Hence, the volume of the figure will be equal to 1176 Cubic cm.

Answer:
160 cm³
Step-by-step explanation:
The ratio of the linear dimensions is the square root of the ratio of areas:
scale factor B/A= √(64/144) = 8/12 = 2/3
The ratio of volumes is the cube of the scale factor:
(volume B)/(volume A) = (2/3)³ = 8/27
Then the volume of pyramid B is ...
volume B = (volume A) × (volume B)/(volume A)
= (540 cm³) × (8/27) = 160 cm³ . . . . volume of pyramid B
_____
Equivalently, the ratio of volumes is the 3/2 power of the ratio of areas.
Vb = Va(64/144)^(3/2) = (540 cm³)(4/9)^(3/2) = (540)(8/27) cm³ = 160 cm³

14. Mia saves $28 in 8 weeks. Her sister saves $18 in 24 days. Are the rates at which each sister saves equivalent? Explain your reasoning.
Answer: No, they are not equivalent. They arent equivalent because 28$/56 days= 0.5/day
18$/24 days= 0.75/day
Step-by-step explanation:
Answer:
no they are not equivalent.
Step-by-step explanation:
to start, the question has mias saving rate at weekly and we need to convert that to days so we can compare to her sister. we multiply 8*7 to find the number of days which is 56. we then divide $28 by 56. mias daily saving rate is y= .5x.
for mias sister we divide 18/24 which is .75. her sisters daily saving rate is y=.75x.
this shows that the saving rates for the sisters are not equivalent

The automatic opening device of a military cargo parachute has been designed to open when the parachute is 135 m above the ground. Suppose opening altitude actually has a normal distribution with mean value 135 and standard deviation 35 m. Equipment damage will occur if the parachute opens at an altitude of less than 100 m. What is the probability that there is equipment damage to the payload of at least one of five independently dropped parachutes? (Give your answer to four decimal places.)
Answer:
the probability that there is equipment damage to the payload of at least one of five independently dropped parachutes is 0.4215
Step-by-step explanation:
Let consider Q to be the opening altitude.
The mean μ = 135 m
The standard deviation = 35 m
The probability that the equipment damage will occur if the parachute opens at an altitude of less than 100 m can be computed as follows:
\(P(Q<100) = P(\dfrac{X- 135}{\sigma} < \dfrac{100 - 135}{35}})\)
\(P(Q<100) = P(z< \dfrac{-35}{35}})\)
\(P(Q<100) = P(z<-1)\)
\(P(Q<100) = 0.1587\)
If we represent R to be the number of parachutes which have equipment damage to the payload out of 5 parachutes dropped.
The probability of success = 0.1587
the number of independent parachute n = 5
the probability that there is equipment damage to the payload of at least one of five independently dropped parachutes can be computed as:
P(R ≥ 1) = 1 - P(R < 1)
P(R ≥ 1) = 1 - P(R = 0)
The probability mass function of the binomial expression is:
P(R ≥ 1) = \(1 - (^5_0)(0.1587)^0(1-0.1587)^{5-0}\)
P(R ≥ 1) =\(1 - (\dfrac{5!}{(5-0)!})(0.1587)^0(1-0.1587)^{5-0}\)
P(R ≥ 1) = 1 - 0.5785
P(R ≥ 1) = 0.4215
Hence, the probability that there is equipment damage to the payload of at least one of five independently dropped parachutes is 0.4215

What is Perimeter?
A perimeter is a closed route that covers, surrounds, or outlines a two-dimensional form or length. The circumference of a circle or an ellipse is its perimeter. There are various practical applications for calculating the perimeter.
Solution:
Perimeter of Rectangle = 2*(Length + Breadth)
According to the question
Breadth = 3*Length
Perimeter = 40

Consider the random variable X with cumulative distribution function F(x)=⎩⎨⎧04x21: for x<0: for 0≤x<2: for x≥2 a. Find the 25th percentile and the median of the random variable X. b. Find the probability density function f(x) for the random variable X. c. Compute E[X],E(X2), and V[X] for the random variable X.
a. The 25th percentile of X is 2/3.The median of X is 1/√2. b. the probability density function f(x) is given by f(x) = ⎩⎨⎧0, for x<01/2x3, for 0≤x<20, for x≥2. c. the expected value of X is 3/8.
a. To find the 25th percentile, we need to find the value x for which F(x) = 0.25.
Since F(x) is given by different formulas for different intervals, we need to consider each interval separately.
For x < 0, F(x) = 0. So this interval does not contribute to the percentile we are interested in.
For 0 ≤ x < 2, F(x) = ∫0x f(t) dt = ∫0x (1/4t²) dt = -1/(4x) + 1/4.
Solving -1/(4x) + 1/4 = 0.25 for x, we get x = 2/3.
For x ≥ 2, F(x) = 1. So this interval does not contribute to the percentile we are interested in.
Therefore, the 25th percentile of X is 2/3.
To find the median, we need to find the value x for which F(x) = 0.5.
For x < 0, F(x) = 0. So this interval does not contribute to the median we are interested in.
For 0 ≤ x < 2, F(x) = ∫0x f(t) dt = ∫0x (1/4t²) dt = -1/(4x) + 1/4.
Solving -1/(4x) + 1/4 = 0.5 for x, we get x = 1/√2.
For x ≥ 2, F(x) = 1. So this interval does not contribute to the median we are interested in.
Therefore, the median of X is 1/√2.
b. To find the probability density function f(x), we take the derivative of F(x) in each interval where it is defined:
For x < 0, f(x) = 0.
For 0 ≤ x < 2, f(x) = d/dx F(x) = 1/2x³.
For x ≥ 2, f(x) = d/dx F(x) = 0.
Therefore, the probability density function f(x) is given by f(x) = ⎩⎨⎧0, for x<01/2x3, for 0≤x<20, for x≥2
c. To compute E[X], we use the formula E[X] = ∫x f(x) dx over the entire range of X:
E[X] = ∫0∞ x f(x) dx = ∫0² x (1/2x³) dx = [(-1/4)\(x^{-2}\)]0² = 1/2.
To compute E[X²], we use the formula E[X²] = ∫x² f(x) dx over the entire range of X:
E[X²] = ∫0∞ x² f(x) dx = ∫0² x² (1/2x³) dx = [(-1/4)\(x^{-1}\)]0² = 1/2.
Finally, to compute V[X], we use the formula V[X] = E[X²] - (E[X])²:
V[X] = E[X²] - (E[X])² = 1/2 - (1/2)² = 3/8.
Therefore, the expected value of X is 3/8.

By finding all the four slopes, we can see that the word is ECHA.
How to find the word?We know that the general linear equation can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
We know that if the line passes through (x₁, y₁) and (x₂, y₂) then the slope is:
s = (y₂ - y₁)/(x₂ - x₁)
With that formula we can get the slopes.
1) Using the points (0, 3) and (2, 4).
m = (4 - 3)/(2 - 0) = 1/2, so the letter is E.
2)Using (-1, -12) and (1, -8)
m = (-8 + 12)/(1 + 1) = 4/2 = 2, so the letter is C.
3) We have (2, -6) and (-4, -3) so:
m = (-3 + 6)/(-4 - 2) = 3/-6 = -1/2, so the letter is H
4)we can use the points (0, 3) and (1, 1), so:
m = (1 - 3)/(1 - 0) = -2, so the letter is A
Then the word is ECHA
