The probability tree has been drawn below and the probability that Lyn
walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks.
What is probability?The probability of an event occurring is defined by probability.
Do not take underestimate probability it has several uses in daily life whether forecasts like that.
As per the given probability tree,
(a)
The probability in branches adds to 1 thus,
0.2 + probability that she walks to the shop = 1
Probability that she walks to the shop = 1 - 0.2 = 0.8
The probability in the same branches multiplies as,
The probability that she took a bus to the shop x from the bus she again took the bus.
Similarly, the tree diagram has been drawn below.
(b)
The probability is 0.88 lies in that Lyn walks at least one way 0.88 is when she reaches the shop by bus and from the bus, she walks.
Hence "walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks".

A square and a rectangle have equal area.The rectangle is 64 cm by 81 cm. What is the perimeter of the square?
Answer:
2592 cm
Step-by-step explanation:
square area = x²
rectangle area = bh
so
x² = bh
since the areas are equal
b and h are in the problem as 64 and 81
x² = 64x81
x² = 5184
divide by 2
x = 2592 cm

[?]%
Step-by-step explanation:
The probability of spinning a one can be written as a fraction. One out of five sections contain a '1' and so, the probability of spinning a one is 1 / 5 . Because 1 is less than half of 5, this outcome can be described as unlikely. The probability of spinning a two is 3 / 5.
You can use the fact that is irrational to answer the questions below. You can also use other facts proven within this exercise. (a) Prove that is irrational. (b) Prove that is irrational. (c) Is it true that the sum of two positive irrational numbers is also irrational
Answer:
See Explanation for proofs
Step-by-step explanation:
Given
See attachment for complete question
Solving (a):
[tex]\frac{\sqrt{2}}{2}[/tex] is irrational
[tex]\sqrt{2} =1.41421356237.....[/tex]
So, we have:
[tex]\frac{\sqrt{2}}{2} = \frac{1.41421356237.....}{2}[/tex]
[tex]\frac{\sqrt{2}}{2} = 0.70710678118....[/tex]
[tex]0.70710678118....[/tex] can not be represented as a fraction of whole numbers.
Hence:
[tex]\frac{\sqrt{2}}{2}[/tex] is irrational
Solving (b):
[tex]\sqrt{2} -2[/tex] is irrational
[tex]\sqrt{2} =1.41421356237.....[/tex]
So, we have:
[tex]\sqrt{2} -2 = 1.41421356237..... - 2[/tex]
[tex]\sqrt{2} -2 = -0.58578643763.....[/tex]
[tex]-0.58578643763.....[/tex] can not be represented as a fraction of whole numbers.
Hence:
[tex]\sqrt{2} -2[/tex] is irrational
Solving (c):
The sum of two positive irrational number is always irrational
Proof Below
If a is irrational and b is also irrational,
then
[tex]a + b = irrational[/tex]
Take for instance:
[tex]a = \sqrt{2[/tex]
[tex]b = \sqrt{8[/tex]
[tex]a + b = \sqrt{2} + \sqrt{8[/tex]
[tex]a + b = \sqrt{2} + \sqrt{4*2[/tex]
[tex]a + b = \sqrt{2} + \sqrt{4}*\sqrt{2[/tex]
[tex]a + b = \sqrt{2} + 2\sqrt{2[/tex]
[tex]a + b = 3\sqrt{2[/tex]
[tex]3\sqrt{2[/tex] is irrational and this is true for the sum of every positive irrational numbers

13.65 = h + 4.88 What the answer
Answer:
h = 8.77
Step-by-step explanation:
Isolate the variable, h. Note the equal sign, what you do to one side, you do to the other. Subtract 4.88 from both sides:
h + 4.88 = 13.65
h + 4.88 (-4.88) = 13.65 (-4.88)
h = 13.65 - 4.88
h = 8.77
8.77 is your answer for h.

Which graph shows only the solutions of the inequality that makes sense for this situation?
Answer:
its on the bottom of the first answer the third one
Step-by-step explanation:
The First graph shows only the solutions to the inequality that makes sense for this situation.
What is Inequality?
Relation between two mathematical identities which is not equal that is it can be either greater than or less than or greater and equals to or less and equals to etc, is called Inequality.
In the given problem the variable is the number of cars.
Let us assume that the variable c represents the variable quantity which is the number of cars for the inequality.
Now we know that number of cars is always a positive and whole number.
So the suitable inequality to represent the condition that the number of cars is not more than 7 that is less than or equals to 7 is,
[tex]c \leq 7[/tex]
So the solutions are c=0,1,2,3,4,5,6,7
Hence the first graph shows the correct solution for the given inequality condition.

Answer:
Step-by-step explanation:
The sum of angles in a triangle is 180 degrees. So the third angle in the triangle is
90+32+a=180
a+122=180
a=58
Now angle x is adjacent to angle a so their sum must equal 180 degrees so
x+58=180
x=122 degrees

In the function f(x), x is replaced with 3x.
f(x)=1/2sin(x)−4
What effect does this have on the graph of the function?
A. The graph is vertically stretched by a factor of 1//3.
B. The graph is vertically compressed by a factor of 1/3.
C. The graph is horizontally stretched by a factor of 1/3.
D. The graph is horizontally compressed by a factor of 1/3.
Just took the test, so the answer is...
D. Horizontally compressed by a factor of 1/3
[tex]f(x)=\frac{1}{2}sin(x)-4[/tex] is horizontally compressed by a factor of 1/3 to get [tex]f(x)=\frac{1}{2}sin(3x)-4[/tex]
Option D is correct
What is horizontal compression?
Note that:
If a function [tex]f(x)=Asin(x)[/tex] is transformed to [tex]g(x)=Asin(kx)[/tex], it means that the function f(x) is horizontally compressed by 1/k
Relating this rule to the given function [tex]f(x)=\frac{1}{2}sin(x)-4[/tex]
If x is replaced with 3x, the function will become:
[tex]f(x)=\frac{1}{2}sin(3x)-4[/tex]
This means that the graph of [tex]f(x)=\frac{1}{2}sin(x)-4[/tex] is horizontally compressed by a factor of 1/3 to get [tex]f(x)=\frac{1}{2}sin(3x)-4[/tex]
