What is the probability of flipping a coin 3times and getting 3tailsin a row?
Answer:
1/8
Step-by-step explanation:
The probability of getting tails on a single flip is 1/2.
Each of the flips is an independent event so you must multiply the probability of getting tails on each flip together.
So, your answer will look like this
[tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] ; which equals;
1/8
Answer:
1/8
Step-by-step explanation:
To calculate the probability you have to name all possible results first. If you mark a result of a single coin flip as H for heads or T for tails all results of 3 flips can be written as:
Ω = { ( H , H , H ) , ( H , H , T ) , ( H , T , H) , ( H , T , T ) , ( T , H , H ) , ( T , H , T ) , ( T ,T , H ) , ( T , T , T ) }
Each triplet contains results on 1st, 2 nd and 3 rd coin. So you can see that in total there are 8 elementary events in Ω.
| Ω | = 8
Now we have to define event A of getting tails three times.
The only elementary event which satisfies this condition is ( T , T , T ) so we can write that:
A = { ( T, T , T ) }
| A | = 1
Now according to the (classic) definition of probability we can write, that:
P ( A ) = | A|/ | Ω | = 1 /8
So finally we can write the answer:
The Probability of getting 3 tails in 3 coin flips is 1 /8 .
Determine the area of the parallelogram.use proper units
Answer:
180 in^2
Step-by-step explanation:
to find the height you need to look at the triangle and apply pythagorean theorem
5^2=x^2=13^2
25+x^2=169
x^2=144
x=12
now we can find the area of the parallelogram:
b*h=area
15*12=180 in^2
The area of the parallelogram is 180 in^2
Find the volume of the cone in terms of pi. 405TT cm3 324TT cm3
405TT cm3 72TT cm3
The volume of the cone in terms of pi is 324π cubic cm.
What is volume of cone?Volume in mathematics describes how much space a three-dimensional item takes up. It is a measurement of the object's capacity, or the volume of fluid it can store. Typically, cubic units like cubic metres (m3) or cubic centimetres are used to determine an object's volume.
A three-dimensional object's shape affects the formula used to determine its volume. A rectangular prism's volume, for instance, can be determined by multiplying its length, width, and height.
The volume of the cone is given by the formula:
V = (1/3)πr²h
Now, for r = 9 and h = 12 we have:
V = (1/3)πr²h
V = (1/3)π(9²)(12)
V = 324π cubic cm
Hence, the volume of the cone in terms of pi is 324π cubic cm.

Zach has an above-ground pool that has a radius of 5.5 feet. He wants to put a new wall liner around his pool and needs to know the circumference of the pool. Find the circumference of the pool to the nearest hundredth.
Answer: 34.54feet
Step-by-step explanation:
Thw circumference of the pool will be calculated by using the formula:
= 2πr
where
π = 3.14
r = 5.5
Therefore, circumference = 2πr
= 2 × 3.14 × 5.5
= 34.54feet
Therefore, the circumference of the pool to the nearest hundredth is 34.54feet.

The amount of the money that they've raised.
Sami was asked to solve the following system of equations using substitution.
y=6x -4
y=2x
Here is the work that sami did:
2x = 6x -4
8x = -4
x = -0.5
And then to find y: y= 2 (-0.5) = -1
so Sami's answer for the point of intersection was (-0.5, -1).
Clearly state Sami's one error and then give the correct ordered pair for where the lines cross.
Answer:
see explanation
Step-by-step explanation:
Sami's error is in the second line of working
2x = 6x - 4 ← correct substitution ( subtract 6x from both sides, Sami has added 6x )
- 4x = - 4 ← correct second line ( divide both sides by - 4 )
x = 1
Substitute x = 1 into either of the 2 equations and evaluate for y
Substituting into the second equation
y = 2x = 2(1) = 2
solution is (1, 2 )

Fairview is 15 kilometers due north of the airport, and Lowell is due east of the airport. If the
distance between Fairview and Lowell is 17 kilometers, how far is Lowell from the airport?
Answer:
8km
Step-by-step explanation:
The three points form a right-angled triangle with 15km as the height and 17km as the hypotenuse.
To find the distance between Lowell and the port which is the base use the pythagorean theorem.
=√17² - 15²

Nina mixed 2 ⅛ pounds of apples, 1 ½ pounds of berries, and 1 ¼ pounds of grapes for a salad. She set aside ⅓ of the slad for dinner and put the rest in a container for later. How many pounds of salad did she put in the container?
Answer: [tex]\dfrac{13}{4}\ \text{or}\ 3\ \dfrac{1}{4}\ \text{Pounds}[/tex]
Step-by-step explanation:
Given
Nina mixed [tex]2\ \frac{1}{8}[/tex] pounds of apples, [tex]1\ \frac{1}{2}[/tex] pounds of berries, and [tex]1\ \frac{1}{4}[/tex] pounds of grapes.
Total salad is
[tex]\Rightarrow \dfrac{2\times 8+1}{8}+\dfrac{1\times 2+1}{2}+\dfrac{1\times 4+1}{4}\\\\\Rightarrow \dfrac{17}{8}+\dfrac{3}{2}+\dfrac{5}{4}=\dfrac{17+12+10}{8}\\\\\Rightarrow \dfrac{39}{8}\ \text{Pounds}[/tex]
Now, one-third of the salad is kept aside and the remaining is put in the container.
Amount of salad Put in the container is
[tex]\Rightarrow (1-\dfrac{1}{3})\cdot (\dfrac{39}{8})=\dfrac{13}{4}\ \text{Pounds}[/tex]
