Suppose a die is rolled twice and let P(A) = 1/2 P(B) = 1/3 find the requested probability
Answer:
Step-by-step explanation:
P(AUB)=P(A)+P(B)+P(A∧B),P(A∧B)=0 as both the events are independent.
P(AUB)=1/2+1/3=(3+2)/6=5/6
The probability value of P(A u B) is 2/3
How to determine the probability?The probability values are given as:
P(A) = 1/2
P(B) = 1/3
The required probability is then calculated using:
P(A u B) = P(A) + P(B) - P(A) * P(B)
This gives
P(A u B) = 1/2 + 1/3 - 1/2 * 1/3
Evaluate the product
P(A u B) = 1/2 + 1/3 - 1/6
Take the LCM
P(A u B) = (3 + 2 - 1)/6
Evaluate
P(A u B) = 2/3
Hence, the probability value of P(A u B) is 2/3

1 1/4 pints how many ounces
Answer:
20 oz
Step-by-step explanation:
Answer:
Your answer would be 20. Just multiply the volume value by 20.
If x^3 - 5x - 4x + 20 is going to factor, then one of these combinations is going to “work”, that is, the polynomial will divide evenly and give f(k) = 0 according to the Factor Theorem. So the best thing to do is employ a little trail and error. Let’s start with the smaller numbers, they will be easier to evaluate.
1. Substitute for x: 1, -1, 2, -2, 4, -4 ...20, -20.
Step-by-step explanation:
x^3 - 5x^2 - 4x + 20 (I'm assuming this is what you meant)
(1)^3 - 5(1)^2 - 4(1) + 20 = 1 - 5 - 4 + 20 = 12
(-1)^3 - 5(-1)^2 - 4(-1) + 20 = -1 - 5 + 4 + 20 = 18
(2)^3 - 5(2)^2 - 4(2) + 20 = 8 - 20 - 8 + 20 = 0
Now I know (x-2) is a factor of the polynomial.
Synthetic division
2 | 1. -5. -4. 20
| 2. -6. -20
-----------------------------
1. -3. -10. 0
x^2 -3x -10
Factor -> (x-5)(x+2)
So the factors of the original polynomial are (x-5), (x+2), and (x-2)
f(x) = 0 when x = -2,2,or 5
jasmine sells beaded jewelry. she calculates the price at which she sells the jewelry by adding a percent markup to the amount it costs her to make the jewelry
Jasmine calculates the selling price of her jewelry by adding a markup percentage to the cost price. The sale price is equivalent to the cost price plus the percentage markup applied to this cost. For example, if the jewelry cost is $10 with a markup of 20%, the selling price will become $12.
Explanation:Jasmine's method of pricing involves costs and percentage markup into consideration. To determine the selling price, she first calculates the cost to make the jewelry. This could include the cost of beads, thread, and her time. Afterwards, she determines the percentage markup. This is the additional amount on top of the cost price to generate profit. The equation can be written as: Selling price = Cost price + (Percent markup/100 * Cost Price).
For example, if it costs her $10 to make a piece of jewelry and she uses a markup of 20%, the amount of markup added would be $2 (20/100 x $10). Therefore, she would sell the jewelry for $12 ($10 + $2).

rady White weighed 197 1/2 pounds when he decided to join a gym to lose some weight. At the end of the first month, he weighed 191 3/8 pounds. (Enter your answers as simplified mixed number
Brady White lost 4 pounds in the first month, leaving him at 193 pounds. To reach his goal weight of 184 pounds, he needs to lose an additional 9 pounds.
(a) To find out how much weight Brady White lost in the first month, we subtract his weight at the end of the month from his initial weight.
Initial weight = 197 pounds
Weight at the end of the first month = 193 pounds
So, the weight lost = Initial weight - Weight at the end of the first month
= 197 pounds - 193 pounds
= 4 pounds
Therefore, Brady White lost 4 pounds in the first month.
(b) To determine how much more weight Brady needs to lose to reach his goal of 184 pounds, we need to find the difference between his current weight and his goal weight.
Current weight = 193 pounds
Goal weight = 184 pounds
So, the amount of weight Brady needs to lose = Current weight - Goal weight
= 193 pounds - 184 pounds
= 9 pounds
Therefore, Brady needs to lose 9 more pounds to reach his goal weight of 184 pounds.

[tex]x^2 - 12x + 36 = (x-6)(x-6)[/tex]
Solution:
Given that,
[tex]x^2 - 12x + 36[/tex]
We have to find the factored form
From given,
[tex]x^2-12x+36\\\\\mathrm{Rewrite\:}36\mathrm{\:as\:}6^2\\\\x^2-12x+6^2\\\\\mathrm{Rewrite\:}12x\mathrm{\:as\:}2x\cdot \:6\\\\x^2-2x\cdot \:6+6^2\\\\\mathrm{Apply\:Perfect\:Square\:Formula}:\quad \left(a-b\right)^2=a^2-2ab+b^2\\\\a=x,\:b=6\\\\Therefore,\\\\x^2-12x+36 = \left(x-6\right)^2\\\\Which\ is\\\\x^2-12x+36 = (x - 6)(x - 6)[/tex]
Thus the given expression is factored
Final answer:
The expression x²−12x+36 is factored as (x-6)(x-6) or (x-6)².
Explanation:
The expression x²−12x+36 represents a quadratic equation. To factor this expression, we look for two numbers that both add to the middle term, -12, and multiply to the constant term, 36. The numbers that fit this requirement are -6 and -6, since (-6) + (-6) = -12 and (-6) × (-6) = 36. Therefore, the expression in factored form is (x-6)(x-6), which can also be written as (x-6)².
Leah and Christopher work at a dry cleaners ironing shirts. Leah can iron 25 shirts per hour, and Christopher can iron 15 shirts per hour. Leah and Christopher worked a combined 13 hours and ironed 265 shirts. Write a system of equations that could be used to determine the number of hours Leah worked and the number of hours Christopher worked. Define the variables that you use to write the system.
25x + 15y = 265
x+y = 13
Step-by-step explanation:
Step 1:
Given
Number of shirts Leah can iron in an hour = 25 shirts
Number of shirts Christopher can iron in an hour = 15 shirts
Total number of hours worked by both = 13 hours
Total number of shirts ironed by them = 265 shirts
Step 2 :
Let x represent the number of hours Leah works and y represent the number of hours Christopher works
Leah irons 25 shirts in one hour, so in x hours he would iron 25x shirts
Christopher irons 15 shirts in one hour, so in y hours he would iron 15y shirts
Given total shirts ironed by them together is 265 , we have
25x + 15y = 265
They worked a combined of 13 hours, so
x+y = 13
Step 3:
The system of equations that could be used to determine the number of hours Leah worked and the number of hours Christopher worked are ,
25x + 15y = 265
x+y = 13
Answer:
System of Equations:
x + y = 13
25x + 15y = 265
x = number of hours Leah works
y = the number of hours Christopher works
On average, Ainsley and her friends could complete 44 sit-ups in one minute. The number of sit-ups done by each of her friends is listed below. How many did Ainsley complete? *
47, 46, 38, 45, 41
Answer:
47
Step-by-step explanation:
The numbers given as 47, 46, 38, 45, 41 represent 5 people and adding Ainsley, they are 6 people.
The sum of individual sit ups by the 5 will be
47+46+38+45+41=217
Since the mean for 6 people is 44, it means their sum is 6*44=264
Getting the difference between the sum for 6 people and the sum for five people we get that
264-217=47
This is the number of sit-ups for the sixth person who is Ansley

A square has a perimeter of 32 inches what the length and width of the square
The length and width of square is 8 inches.
Step-by-step explanation:
Given,
Perimeter of square = 32 inches
We know that all sides of square are equal, therefore,
Length = width = s
Perimeter of square = 4s
[tex]32=4s\\4s=32[/tex]
Dividing both sides by 4
[tex]\frac{4s}{4}=\frac{32}{4}\\s=8[/tex]
Therefore,
The length and width of square is 8 inches.
Final answer:
The length and width of the square are each 8 inches, calculated by dividing the given perimeter of 32 inches by the number of sides of a square, which is 4.
Explanation:
To find the length and width of a square given its perimeter, we need to recall that all four sides of a square are of equal length. Since the perimeter of the square is 32 inches, we divide this number by 4 to find the length of one side. So, the length and width of the square are:
32 inches ÷ 4 = 8 inches.
Therefore, each side of the square is 8 inches long.
Find the equation of the line that is perpendicular to y = –3x + 1 and passes though the point (6, 3).
Answer:
y = [tex]\frac{1}{3}[/tex] x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 1 ← is in slope- intercept form
with slope m = - 3
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-3}[/tex] = [tex]\frac{1}{3}[/tex], thus
y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation of the perpendicular line
To find c substitute (6, 3) into the partial equation
3 = 2 + c ⇒ c = 3 - 2 = 1
y = [tex]\frac{1}{3}[/tex] x + 1 ← equation of perpendicular line
The equation of the line that is perpendicular to y = -3x + 1 and passes through the point (6, 3) is y = 1/3x + 1
Explanation:To find the equation of the line that is perpendicular to y = -3x + 1 and passes through the point (6, 3), we first need to find the slope of our new line. The slope of a line perpendicular to another is the negative reciprocal of the original slope. Since the slope of the original line is -3, the slope of the new, perpendicular line will be 1/3.
The general equation of a line is y = mx + b, where m is the slope and b is the y-intercept. We already have the slope, m = 1/3, and a point through which the line passes (6, 3). Substituting these values into the equation gives us 3 = 1/3 * 6 + b. Solving for b gives us b = 1.
Therefore, the equation of the line that is perpendicular to y = -3x + 1 and passes through the point (6, 3) is y = 1/3x + 1.
