What is a triangular pyramid?Take a traingle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first traingle and when they're taken together, they form a closed object, called as a triangular pyramid
What is a rectangular pyramid?Take a rectangle. This is the base. Now take 4 triangles such that each of them are connected to one-one side of the base rectangle and when they're taken together, they form a closed object. That shape is called rectangular pyramid.
What is a triangular prism?Connect three rectangles edge to edge. Now close their triangular mouths from both ends. That shape is called a triangular prism.
What are vertices, faces and edges?Faces are planar mathematical objects. Like a triangle, a rectangle etc. Edges are those line segments, which are on the edge of the faces (of some object considered).
Vertices are points of intersections of different edges.
The missing figure is attached below.
It consists of 3 rectangles joined edge to edge, and have two triangular ends in the shape they form, thus, making a triangular prism.

Jimmy's fishing boat is sailing near the shoreline when a lighthouse on the top of a 250-foot cliff is lit up. If Jimmy's sight line is 400 feet away from the lighthouse, what is the angle of depression from the lighthouse to the fishing
Answers
Answer:
32.0054
Step-by-step explanation:
i think
The angle of depression is approximately 32.01 degrees.
To find the angle of depression, we can use the concept of trigonometry. Specifically, we use the tangent function, which relates the height of the lighthouse to the distance from the lighthouse to Jimmy's boat.
Steps to solve:
Let θ be the angle of depression.The height of the lighthouse (opposite side) is 250 feet.The distance from the lighthouse to the boat (adjacent side) is 400 feet.Use the tangent function: tan(θ) = opposite / adjacent.Substitute the values: tan(θ) = 250 / 400.Simplify the fraction: tan(θ) = 0.625.Find the angle by taking the arctangent: θ = [tex]tan^{-1}[/tex](0.625).The result is approximately: θ ≈ 32.01 degrees.Therefore, the angle of depression from the lighthouse to the fishing boat is about 32.01 degrees.

What is the standard deviation of the data set? Round your answer to the nearest tenth.
A. 4.8
B. 4.6
C. 4.7
D. 4.3
Answers
Answer:
c. 4.7
Step-by-step explanation:
first, you find the mean of data set:
83 + 85 + 82 + 93 + 83 + 84 + 95 + 87 + 86 + 94 = 872/10 = 87.2
then, you take each number and subtract the mean and square it:
(87.2 - 83)² = (4.2)² = 17.64
(87.2 - 85)² = (2.2)² = 4.84
(87.2 - 82)² = (5.2)² = 27.04
(93 - 87.2)² = (5.8)² = 33.64
(87.2 - 83)² = (4.2)² = 17.64
(87.2 - 84)² = (3.2)² = 10.24
(95 - 87.2)² = (7.8)² = 60.84
(87.2 - 87)² = (0.2)² = 0.04
(87.2 - 86)² = (1.2)² = 1.44
(94 - 87.2)² = (6.8)² = 46.24
now, find the mean of the squared numbers:
17.64 + 4.84 + 27.04 + 33.64 + 17.64 + 10.24 + 60.84 + 0.04 + 1.44 + 46.24 = 219.6/10 = 21.96
then, take the square root of the number you just got:
√21.96 = 4.68
and last but not least, round to the nearest tenth: 4.7

Step-by-step explanation:
The probability of rolling an even number and then a 3 is,
⇒ 1 / 12
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Now, the probability of rolling an even number on the first roll.
Then, There are three even numbers 2, 4, and 6 out of the 6 possible outcomes,
so the probability of rolling an even number on the first roll is,
= 3/6,
= 1/2
And, For the probability of rolling a 3 on the second roll.
There is only one outcome that will result in a 3 out of the six possible outcomes,
so the probability of rolling a 3 on the second roll is 1/6.
Now we can multiply the two probabilities together to find the probability of rolling an even number on the first roll and then a 3 on the second roll:
1/2 x 1/6 = 1/12
Hence, the probability of rolling an even number and then a 3 is,
⇒ 1 / 12

Find the 4th term in the sequence.
Answers
The 4th term in the sequence is -17.
To find the 4th term in the sequence defined by the recursive formula [tex]\(a(n) = a(n-1) - 5\)[/tex] with the initial condition [tex]\(a(1) = -2\)[/tex], you can use the recursive formula to compute each term. Let's find the first few terms:
1. [tex]\(a(1) = -2\)[/tex] (given)
2. [tex]\(a(2) = a(1) - 5 = -2 - 5 = -7\)[/tex] (using the recursive formula)
3. [tex]\(a(3) = a(2) - 5 = -7 - 5 = -12\)[/tex] (using the recursive formula)
4. [tex]\(a(4) = a(3) - 5 = -12 - 5 = -17\)[/tex] (using the recursive formula)
The recursive formula tells us how to calculate each term in the sequence based on the previous term. Starting with \(a(1)\), we use the formula to find [tex]\(a(2)\)[/tex], then use [tex]\(a(2)\) to find \(a(3)\)[/tex], and so on.
So, the 4th term [tex](\(a(4)\))[/tex] is found by taking the previous term [tex](\(a(3)\))[/tex], which is -12, and subtracting 5.
Complete the question:

Find the 4th term in the sequence.
Final answer:
The 4th term in the sequence defined by a(1) = -2 and a(n) = a(n − 1) − 5 is -17, which is found by successively subtracting 5 from the previous term.
Explanation:
To find the 4th term in a sequence where a(1) = -2 and a(n) = a(n − 1) − 5, we will use the recurrence relation to determine each subsequent term:
First term (a(1)) is given as -2.The second term (a(2)) equals a(1) - 5 = -2 - 5 = -7.The third term (a(3)) equals a(2) - 5 = -7 - 5 = -12.The fourth term (a(4)) equals a(3) - 5 = -12 - 5 = -17.Therefore, the 4th term in the sequence is -17.

There is no question asked, and the statement is incomplete, but this describes Series and Sequence. They are usually arithmetic or geometric progressions. A set of numbers are written to follow a particular pattern, when the pattern is clear, one can find any number of the sequence or series.
For example, consider the sequence below (Arithmetic Progression)
2, 4, 6, 8, ...
This sequence has a particular pattern.
The first term of the sequence is
a = 2
The common difference d, which is the difference between any two consecutive terms is
d = 2
The nth term, which is the formula that defines every single term of the sequence is given as
Tn = a + (n - 1)d
Check
T1 = a = 2
T2 = 2 + 2 = 4
T3 = 2 + 2(2) = 6
T4 = 2 + 2(3) = 8

A bag contains 8 red marbles, 7 blue marbles and 5 green marbles. If two marbles are drawn out of the bag, what is the exact probability that both marbles drawn will be red?
Answers
The exact probability that both marbles drawn will be red is 4/25.
Given that:
Number of red marbles in the bag, R = 8
Number of blue marbles in the bag, B = 7
Number of green marbles in the bag, G = 5
The total number of marbles in the bag is:
T = 8 + 7 + 5
= 20
The probability of drawing a colored marble is the number of marbles of that color by the total number of marbles.
So, P(R) = 8/20, P(B) = 7/20 and P(G) = 5/20
If two marbles are drawn out of the bag, the probability that both marbles are red is:
P = P(R) P(R)
= (8/20)(8/20)
= (2/5)(2/5)
= 4/25
Hence, the probability s 4/25.

Final answer:
The exact probability of drawing two red marbles from the bag without replacement is the product of the individual probabilities, calculated as (2/5) × (7/19).
Explanation:
To find the probability that both marbles drawn from a bag will be red, given the bag contains 8 red marbles, 7 blue marbles, and 5 green marbles, we need to calculate the probability of drawing one red marble and then another red marble without replacement.
The total number of marbles in the bag is 8 red + 7 blue + 5 green = 20 marbles. The probability of drawing the first red marble is 8/20, which simplifies to 2/5. After drawing one red marble, there are now 7 red marbles left and the total drops to 19 marbles. The probability of drawing a second red marble is now 7/19.
To find the probability of both events happening, we multiply the probabilities of each event: (2/5) × (7/19). Therefore, the exact probability of drawing two red marbles in succession without replacement is (2/5) × (7/19).
