Answer:
0.85% probability that the first two are good and the last three are spoiled
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the first two jugs is not important, as is not the order in which the last three are selected. So we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Desired outcomes:
2 spoiled, from a set of 43-11 = 32.
3 spoiled, from a set of 11.
So
[tex]D = C_{32,2}*C_{11,3} = \frac{32!}{2!(32-2)!}*\frac{11!}{3!(11-3)!} = 982080[/tex]
Total outcomes:
5 jugs from a set of 43.
[tex]T = C_{43,5} = \frac{43!}{5!(43-5)!} = 115511760[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{982080}{115511760} = 0.0085[/tex]
0.85% probability that the first two are good and the last three are spoiled

standard deck of 525252 cards contains 444 suits: hearts, clubs, diamonds, and spades. Each suit consists of cards numbered 222 through 101010, a jack, a queen, a king, and an ace.
Bashir decides to pick one card at random from a standard deck of 525252 cards. Let FFF be the event that he chooses a face card (a jack, queen, or king of any suit) and SSS be the event that he chooses a spade.
What is P(F\text{ or }S)P(F or S)P, left parenthesis, F, start text, space, o, r, space, end text, S, right parenthesis, the probability that the card Bashir chooses is either a face card or a spade?
Answer:
0.4231 or 42.31%
Step-by-step explanation:
In a standard 52 card deck there are 13 spade cards (52/4) and there are 12 face cards (4 suits x 3 face cards). Moreover, 3 cards are both face and spade cards.
Therefore, the probability that the card Bashir chooses is either a face card or a spade is given by:
[tex]P(F\ or\ S)=P(F)+P(S)-P(F\ and\ S)\\P(F\ or\ S)=\frac{13}{52} +\frac{12}{52} -\frac{3}{52}\\P(F\ or\ S)=0.4231[/tex]
The probability is 0.4231 or 42.31%

Mary has taxable income of $40,000, with short-term capital gains of $2,500. What will be her capital gains tax rate and tax owed? Single Taxpayers: Income Brackets Tax Rate Income Bracket 10% 0 to 9,525 12% 9,526 to 38,700 22% 38,701 to 82,500 24% 82,501 to 157,500 32% 157,501 to 200,000 35% 200,001 to 500,000 37% > 500,000 Single Taxpayers: Qualified Dividends and Long-Term Capital Gains Tax Rate Income Bracket 0% 0 to 38,600 15% 38,601 to 425,800 20% > 425,800 A. 0% tax rate with no taxes owed B. 15% tax rate with $375 in taxes owed C. 22% tax rate with $550 in taxes owed D. 24% tax rate with $600 in taxes owe
Answer:
The correct option is B,15% tax rate with $375 in taxes owed
Step-by-step explanation:
Mary has a taxable income of $40,000 which implies that Mary falls into tax bracket of capital gains tax of 15% for taxable income between $38,601 and $425,800.
The amount capital gains tax payable is however the capital gains itself multiplied by the percentage applicable of 15% not the entire taxable income since that consisted of other income from other sources aside from capital gains
capital gains tax=$2500*15%=$375
Answer: Its C, the rationale is that short-term capital gains are taxed at income tax rate
Step-by-step explanation:
$2500=$550 22%

Stefani is making a square quilt with a side length of x + 2 feet. If the quilt will have an area of 36 feet, what is the value of x?
Answer:
The value of x is 4
Step-by-step explanation:
Mathematically, we can calculate the area of the quilt by having the product of the side of the quilt by itself
Mathematically, the area of the quilt = L^2
This is (x + 2) * (x + 2)
This product is equal to 36 feet square
Thus;
(x + 2)^2 = 36
(x + 2)^2 = 6^2
Since the powers are equal, we equate the bases
x + 2 = 6
x = 6-2
x = 4

When Elena throws a shot put during track and field practice, it travels an average of 26 feet with a standard deviation of 3 feet, and the distribution of lengths is approximately normal. Approximately what percentage of her shots will travel less than 23 feet? *
Answer:
15.87%, that is, approxiately 16% of of her shots will travel less than 23 feet.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 26, \sigma = 3[/tex]
Approximately what percentage of her shots will travel less than 23 feet?
This is the pvalue of Z when X = 23. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{23 - 26}{3}[/tex]
[tex]Z = -1[/tex]
[tex]Z = -1[/tex] has a pvalue of 0.1587.
15.87%, that is, approxiately 16% of of her shots will travel less than 23 feet.

The table shows ordered pairs of the function . What is the value of y when ?
A 2-column table with 6 rows. The first column is labeled x with entries negative 3, negative 1, 1, 4, 8, 10. The second column is labeled y with entries 14, 10, 6, 0, question mark, negative 12.
–20
–8
8
48
Answer:
(B) -8
Step-by-step explanation:
Given the 2-column table below:
[tex]\left|\begin{array}{c|c}x&y\\--&--\\-3&14\\-1&10\\1&6\\4&0\\8&?\\10&-12\end{array}\right|[/tex]
Taking the pair (-3,14) and (-1,10)
[tex]Slope, m=\dfrac{10-14}{-1-(-3)} =\dfrac{-4}{2} =-2[/tex]
Taking the pair (1,6) and (4,0)
Slope, [tex]m=\dfrac{0-6}{4-1} =\dfrac{-6}{3} =-2[/tex]
Since the slope is constant, the table represents a linear function whose slope is -2. Therefore:
Taking the pair (8,y) and (4,0)
Slope, [tex]m=\dfrac{0-y}{4-8} =-2[/tex]
[tex]\dfrac{-y}{-4} =-2\\y=-2*4=-8[/tex]
Therefore, the value of ? on the y-column is -8.
Answer:
-8
Step-by-step explanation:
Rearrange w=3(2a+b)-4 to make a the subject
w = 3(2a + b) - 4
First, add 4 to both sides:
w (+4) = 3(2a + b) - 4 (+4)
w + 4 = 3(2a + b)
Next, divide 3 from both sides:
(w + 4)/3 = (3(2a + b))/3
(w + 4)/3 = 2a + b
Next, subtract b from both sides:
((w + 4)/3) - b = 2a + b (-b)
(w + 4)/3 - b = 2a
Finally, divide 2 from both sides:
((w + 4)/3 - b)/2 = (2a)/2
a = (((w + 4)/3) - b)/2
a = (((w + 4)/3) - b)/2 is your answer.

Answer:
[tex]\frac{w}{6} +\frac{2}{3} -\frac{3b}{6}[/tex]=a
Step-by-step explanation:
w=3(2a+b)-4 ---> add 4 to both sides
w+4=3(2a+b) --> distribute the 3
w+4= 6a+3b--> subtract 3b from both sides
w+4-3b=6a ---> to isolate the a divide both sides by 6
[tex]\frac{w}{6} +\frac{2}{3} -\frac{3b}{6}[/tex]= a ---> I hope this was what you were looking for

Write an equation of the line that passes through each pair of points.
Answer: y=-2x + 3
Step-by-step explanation:
(0,3) and (2,-1)
3-(-1)= 4
0-2= -2
4/-2= -2 so the slope is -2 and we already know the y intercept is 3 because that is when x is 0.
so the equation will y= -2x + 3

1.Nestor needs 750 centimeters of rope. Rope comes in length of 4 ½ meters and 9 meters at the hardware store 9 meters at the hardware store. Which length of rope should Nestor buy? Example: 4 ½ meters = centimeters 9 meters = centimeters Which length is greater? Explain your findings
Answer:
Nestor needs to buy 7 ½ meters rope
And: the length of the rope that is greater is : 9 meters
Step-by-step explanation:
From the length conversion table:
We know that:
1 meters = 100 centimetres
We are told that Nestor needs 750 centimeters of rope
Now; these ropes comes in the length of 4 ½ meters and 9 meters at the hardware store
To determine the length of rope should Nestor buy? ; we will need to first convert the length of the ropes in meters to centimeters first;
so
4 ½ meters to centimeters = 4 ½ × 100 centimeters = 450 centimeters
9 meters to centimeters = 9 × 100 centimeters = 900 centimeters
And Nestor needs to purchase 750 centimeters of rope;
So if ;
4 ½ meters = 450 centimeters
Then ; let x meters = 750 centimeters
So;
x meters × 450 centimeters = 4 ½ meters × 750 centimeters
x meters = (4 ½ meters × 750 centimeters) / 450 centimeters
x = 7 ½ meters
Also; if
9 meters = 900 centimeters
Then ; let x meters = 750 centimeters
So;
x meters × 900 centimeters = 9 meters × 750 centimeters
x meters = (9 meters × 750 centimeters) / 900 centimeters
x = 7 ½ meters
Thus; Nestor needs to buy 7 ½ meters rope
And: the length of the rope that is greater is : 9 meters
Answer:
Nestor should buy the rope that is 9 meters long
Step-by-step explanation:
Nestor will need to buy a rope that is longer than 750 centimeters so that he can easily cut it to serve his need. If he buys a shorter rope, it will be a lot more difficult to join to get the required length that he needs.
To know the length of his various options and determine the one that is best, we will convert all the ropes to the same unit (cm) and compare is with the required length.
Rope A: 4.5 meters
1 m = 100 cm
4. 5 cm = 4.5 X 100 = 450 cm
This is clearly shorter than is required
Rope B: 9 meters
1 m = 100 cm
9 m = 9 X 100 = 900 cm
This is clearly longer than is required, hence should be Nestor's choice
