22 -- Here is a solid made from a square-based pyramid and a cube.
Each edge of the solid has length 6 cm.
On the centimetre grid, draw the plan of this solid.
How do I draw the plan
Answer:
Step-by-step explanation:
The solid's plan, consisting of a pyramid with a square base and a cube whose edges are each 6 cm long, will be represented in the attached graph.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
To draw the plan of a solid made from a square-based pyramid and a cube, with each edge having a length of 6 cm, you can start by drawing the top view of the cube. Since the edges of the cube have a length of 6 cm, the top view of the cube will be a square with sides of 6 cm.
Next, you can draw the top view of the square-based pyramid.
A square-based pyramid is a pyramid with a square base, so the top view of the pyramid will be a square with sides of 6 cm, just like the top view of the cube. However, the top view of the pyramid will also have four triangular faces extending from the corners of the square, each with a height of 6 cm.
To complete the plan of the solid, you can simply place the top view of the pyramid on top of the top view of the cube, aligning the edges of the squares.
The resulting drawing will be the plan of the solid made from a square-based pyramid and a cube, with each edge having a length of 6 cm.

Step-by-step explanation:
Peter, Dan, Harold, and Randy each have a nickel. All four of them flip their nickels at the same time. a. Draw a tree diagram of all the combinations possible when the four boys flip their coins.
You would get something like this. This is because with the first kid, they can get either Heads or Tails, two possibilities.
After this, the second kid can also cause either Heads or Tails but they are building on what the first kid had already done, so four possibilities.
Thsi keeps on multiplying on and on by 2 the more kids who flip a coin.
The probability exists a branch of mathematics in which the events of investigations happening exist estimated.
b) 50% probability that Dan and randy will flip the same thing.
25% of heads and 25% of tails.
What is the classical definition of probability?Probability exists the analysis of the circumstances of event of a result, which exists received by the ratio between favorable cases and possible cases.
b) 50% probability that Dan and randy will flip the same thing.
25% of heads and 25% of tails.

Find the area of the trapezoid
Answer:
The area of this trapezoid is equal to 240 [tex]m^{2}[/tex]
Step-by-step explanation:
The area of a trapezoid can be found by using the following formula...
[tex]Area = \frac{(a + b)h}{2}[/tex] (in this formula a and b are the bases of the trapezoid and h is
the height of the trapezoid).
Now we just substitute the values and get...
[tex]Area = \frac{(a + b)h}{2} = \frac{(9 + 15)(20)}{2} = \frac{480}{2} = 240m^{2}[/tex]
What is 90 divided by 1/3 as a fraction?
Answer:
270/1
Step-by-step explanation:
Here is 90 divided by 1/3 displayed mathematically in colors:
90 ÷ 1/3
The numbers in 90 divided by 1/3 are labeled below:
90 = whole number
1 = numerator
3 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
90x3/1 = 270/1
Answer: 270/1
Step-by-step explanation:
90/1*1/3 you have to do the reciprocal so it turns to 90/1*3/1= 270/1

9. Empty taxis pass by a street corner at a Poisson rate of two per minute and pick up a passenger if one is waiting there. Passengers arrive at the street corner at a Poisson rate of one per minute and wait for a taxi only if there are less than four persons waiting; otherwise they leave and never return. Ella arrives at the street corner at a given time. Find her expected waiting time, given that she joins the queue. Assume that the process is in steady-state.
Answer:
0.37
Step-by-step explanation:
To resolve the given problem we will apply
persistent time Markov chain : n = 0, 1, . . . , 4
n = number of individuals pausing
where The equalization conditions are : πn = ( πn - 1/2 )
Given that :
n = 0,1,2,3,4
π0 = 1/( 1 + 2−1 + 2−2 + 2−3 + 2−4) = 0.52 = 16/31
Also the normal number of travelers found by Ella will be represented as
E(N) = (π1 + 2π2 + 3π3) / ( π0 + π1 + π2 + π3) ------- ( 1 )
where : π1 = 8, π2 = 4, π3 = 2 , π0 = 16/31 input values into equation 1
E ( N ) = 22/30
given that the True to form hanging tight time = 0.5
hence Holding holding time = E(N ) * 0.5
therefore the expected waiting time for Ella = ( 22/30 ) * 0.5 = 0.37
