An experiment consists of rolling a die and then flipping a coin.
The following tree diagram shows the possible outcomes.
A tree diagram in which a center point branches to numbers 1 through 6, which each branch to an H & T.
What is the probability of rolling an even number or flipping a tail?
Enter your answer as a reduced fraction, like this: 3/14
Answers
Using it's concept, it is found that the probability of rolling an even number or flipping a tail is of [tex]\frac{3}{4}[/tex].
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, there are 12 outcomes. Of those, 3 result in an even number and a tail, 3 more in an even number but not tail and 3 in a tail but an odd number, hence there are 9 desired outcomes.
Hence, the probability is given by:
[tex]p = \frac{9}{12} = \frac{3}{4}[/tex]

Answer: 48/44
Step-by-step explanation: if the area is 144 the perimeter is going to be 48. if the area is 121 the perimeter is 44. to find the perimeter you have to find the sides, since it is a square they will all be the same length. you have to find the square of the area since the formula for it is lw. then once you find the length of each side, you multiply it by 4 to find the perimeter. then to find the other question multiply the permimeter by 5.
area of square: side²
=======
side² = 121
side = √121
side = 11 cm

5. During a game of golf, Kayley hits her ball out of a sand trap. The height of the golf ball is modeled by the
equation h=-16r² + 20 - 4, where h is the height in feet and is the time in seconds since the ball was hit.
Find how long it takes Kayley's golf ball to hit the ground.
a. Write the equation that you are trying to solve.
b. Solve the equation by factoring.
Answers
Answer:
(a) [tex]\sf -16r^2+20r-4=0[/tex]
(b) r = 1, r = 1/4
Step-by-step explanation:
Given equation: [tex]\sf h=-16r^2+20r-4[/tex]
where:
h = height (in feet)t = time (in seconds)Question (a)
The ball will hit the ground when h = 0
[tex]\sf \implies-16r^2+20r-4=0[/tex]
Question (b)
To factor [tex]\sf -16r^2+20r-4=0[/tex]
Divide both sides by 4:
[tex]\sf \implies-4r^2+5r-1=0[/tex]
Swap signs:
[tex]\sf \implies 4r^2-5r+1=0[/tex]
Split middle term:
[tex]\sf \implies 4r^2-4r-r+1=0[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\sf \implies 4r(r-1)-(r-1)=0[/tex]
Factor out common term (r - 1):
[tex]\sf \implies (4r-1)(r-1)=0[/tex]
Therefore:
[tex]\sf \implies (4r-1)=0 \implies r=\dfrac14[/tex]
[tex]\sf \implies (r-1)=0 \implies r=1[/tex]

A group of friends wants to go to the amusement park. They have $272 to spend on parking and admission. Parking is $7.75, and tickets cost $37.75 per person, including tax. How many people can go to the amusement park?
Answers
Answer:
7 people
Step-by-step explanation:
Given:
$272 total money for all friends
parking costs $7.75 for all
tickets cost $37.75 per person
Solution;
Take away the money for parking to see how much money we have left for tickets
272 - 7.72 = $ 264.25
We divide the $264.25 to the price of 1 ticket $37.75 to see how many tickets we have money for
264.25 / 37.75 = 7
If we have money for 7 tickets then 7 friends can go to the amusement park.
An orange cone has a exact volume of 120π ft³. What is the height of the cone if the radius is 6ft?
Answers
Answer:
10 ft
Step-by-step explanation:
Given:
Radius ⇒ 6 feetFormula of cone ⇒ V = 1/3πr²hPlug in the values given:
120π=1/3π(6²)hCancel π from both sides and simplify:
120 = 1/3 36h120 = 12hAnswer:
Height = 10The height of the cone if the radius is 6ft is,
⇒ h = 3.18 feet
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
An orange cone has a exact volume of 120π ft³.
And, The radius = 6 feet
Now, We know that;
Volume of cone = πr²h/ 3
Hence, We get;
⇒ 120 = 3.14 × 6² × h / 3
⇒ 120 = 3.14 × 12h
⇒ 120 = 37.68h
⇒ h = 3.18 feet
Thus, The height of the cone if the radius is 6ft is,
⇒ h = 3.18 feet

find the area of the regular polygon.
A) 187.2
B) 887.5
C) 110.4
D) 63
Answers
Answer:
A) 187.2
Step-by-step explanation:
Area of a regular polygon = 1/2(apothem × perimeter)
The perimeter of the triangle can me calculated by multiplying the side length by 3 ( because the polygon shown has 3 sides )
Side length = 20.8 , so perimeter = 3 × 20.8 = 62.4
Now we can find the area
Remember area of a regular polygon = 1/2(apothem × perimeter)
Apothem = 6 and perimeter = 62.4
So area = 1/2(6×62.4)
==> multiply 6 and 62.4
area = 1/2(374.4)
==> multiply 374 and 1/2
area = 187.2

Mathew finds the deepest part of the pond to be 185 meters
Which measurement describes the depth of the pond?
Answers
[tex]\sqrt{196} = 14[/tex], and since [tex]\sqrt{185[/tex] is less than [tex]\sqrt{196}[/tex], the deepest part of the pond is less than 14.
-> The depth of the pond is between 13 and 14 meters.
Or, you can just calculate [tex]\sqrt{185}[/tex] = 13.6014... (between 13 and 14)
The measurement describes the depth of the pond is Between 13 and 14 meters.
What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
Since one side measure 14, and the height (depth) could not be higher than 14 meters .
The length of the pond can be calculated using the Pythagorean theorem as;
length^2 = 36^2 + 14^2
length^2 = 1296 + 196
length^2 = 1492
length = 38.6 m
