You roll a fair four-sided die and a fair five-sided die together. What is the probability of rolling at least one 3. Consider the following table.
Choices:
A. 8/25
B. 4/9
C. 9/20
D. 1/2
E. 2/5
Answers
Answer:
A
Step-by-step explanation:
Bc
Probability of rolling at least one 3 is option E. 2/5.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
Given that, a fair four-sided die and a fair five-sided die are rolled together.
Probability of rolling at least one 3 means that 3 is rolled in any one of the die or both dice.
Sample space of rolling 3 are {(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (1, 3), (2, 3), (4, 3)}
There are 8 chances of getting at least one 3 in any of the die.
Total number of outcomes = 4 × 5 = 20
Probability of getting at least one 3 = 8/20 = 2/5
Hence the required probability is 2/5.

The probability of a tropical storm becomes a hurricane is 0.53. If the weather service predicts 6 more tropical storms, what is the probability that exactly 5 of them become hurricanes?
Answers
Answer:
0.1179
Step-by-step explanation:
Given that :
p = 0.53
n = 6 ; x = 5
P(x = 5)
According to the binomial probability formula :
P(x = r) = nCr * p^r * (1 - p)^(n - r)
P(x = 5) = 6C5 * 0.53^5 * (1 - 0.53)^(6 - 5)
P(x = 5) = 6C5 * 0.53^5 * 0.47^1
P(x = 5) = 6 * 0.53^5 * 0.47^1
P(x = 5) = 0.117931129026
= 0.1179
If Blueface makes 3 songs for 10 hours each day and on wednesday 11 hours how long does blueface make music for
Answers
Answer:

Step-by-step explanation:
Each day....hmm so for like one week?
There are 7 days in a week
Each day except for Wednesday is 10 hours, and on Wednesday it is 11...
Monday = 10
Tuesday = 10
Wednesday = 11
Thursday = 10
Friday = 10
Saturday = 10
Sunday = 10
If you add them all up you get 71 hours. And songs....
Monday = 3
Tuesday = 3
Wednesday = 3
Thursday = 3
Friday = 3
Saturday = 3

Marcus throws a football straight up into the air. After it reaches its maximum height of 20 feet, it descends back to ground. What is the independent and dependent?
Answers
Answer:
Independent = Force used to throw foot ball (Marcus)
Dependent = Maximum Height
Step-by-step explanation:
The independent variable is h and the dependent variable is u.
What is kinematics?The study of motion without considering the mass and the cause of the motion.
We know that the equation of motion is given as,
v² - u² = -2gh
Where v is the final velocity, u is the initial velocity, g is the acceleration due to gravity (9.81), and h is the height of the ball.
We know that the final velocity will be zero at the highest point. Then the equation will be given as,
0² - u² = -2 × 9.81 × h
u² = 19.62h
u = √(19.62h)
Then the independent variable is h and the dependent variable is u.

Dave has 85p ellie has £1.43 How much should ellie give to dave so that they both have the same amount of money
Answers
Answer:
29p
Step-by-step explanation:
Money available with Dave = 85p
Money available with Ellie = £1.43
To find:
How much money should Ellie given to Dave so that they both have the same amount of money?
Solution:
First of all, let us convert £ to p.
1 £ = 100p
1.43£ = 143p
Let number of 'p' that Ellie has to give to Dave so that they have equal amount of money = [tex]x[/tex] p
Money left with Ellie after giving [tex]x[/tex] p to Dave = (143 - [tex]x[/tex])p
Money with Dave after taking [tex]x[/tex] p from Ellie = (85 + [tex]x[/tex])p
As per question statement, money with both of them is same.
i.e.
[tex]143-x=85+x\\\Rightarrow 2x=143-85\\\Rightarrow 2x = 58\\\Rightarrow x = \bold{29p}[/tex]
Therefore, Ellie should give 29p to Dave so that they have same amount of money.
They both will have 1.14£ or 114p each.

At a high school championship game 1200 tickets were sold. Student tickets cost $1.50 each and adult tickets cost $5.00 each. The total revenue collected for the game was $3200. How many of each ticket were sold for the game?
Answers
Answer:
Students= 800
Adults= 400
Step-by-step explanation:
Given data
number of tickets= 1200
let students be x
and adults be y
x+y= 1200--------------------1
'
The total revenue collected for the game was $3200
so
1.5x+5y=3200-------------2
Solve 1 and 2 for x and y
x= 1200-y
put this is 2
1.5( 1200-y)+5y=3200-------------2
1800-1.5y+5y= 3200
3.5y= 3200-1800
3.5y=1400
Divide both sides by 3.5
y= 1400/3.5
y=400
Put y= 400 in 1
x+400= 1200
x= 1200-400
x=800
Catarina and Tom want to buy a rug for a room that is 8 by 12. They want to leave an even strip of flooring uncovered around the edges of the room. How wide a stip willhave if they buy a rug with an area of 32 square feet
Answers
Answer:
The strip would be 2 ft wide
Step-by-step explanation:
Let the strip be x ft long
since it is on either sides, it will take a space each of 2x
So the dimensions of the rug will be;
(8-2x) and (12-2x)
The product of these will give the area of the rug
We have this as;
(8-2x)(12-2x) = 32
96-16x-24x + 4x^2 = 32
4x^2-40x + 96-32 = 0
4x^2 -40x + 64 = 0
x^2 - 10x + 16 = 0
x^2 - 8x - 2x + 16 = 0
x(x-8) -2(x-8) = 0
(x-2)(x-8) = 0
x = 2 or 8
The value 8 will not be possible as it will need to negative dimensions
So the possible dimensions will be;
(8-2(2)) and 12-2(2)
= 8-4 and 12-4
= 4 ft by 8 ft

This equation shows how the time required to ring up a customer is related to the number of items being purchased. t = 4p + 20 The variable p represents the number of items being purchased, and the variable t represents the time required to ring up the customer. If it takes 44 seconds to ring up a customer, how many items are being purchased?
Answers
Answer:
6 items are being purchased
Step-by-step explanation:
Given that variable p represents the number of items being purchased, and the variable t represents the time required to ring up the customer, If it takes 44 seconds to ring up a customer then the number of items being purchased may be computed by substituting the value of t into the given equation
t = 4p + 20.
Using t = 44
44 = 4p + 20
collect like terms or subtract 20 from both sides
44 - 20 = 4p
24 = 4p
Divide both sides by 4
24/4 = p
p = 6
