Levin Furniture buys a living room set with a $4,900 list price and a 50% trade discount. Freight (FOB shipping point) of $45 is not part of the list price. What is the delivered price (including freight) of the living room set, assuming a cash discount of 4/10, n/30, ROG? The invoice had an April 8 date. Levin received the goods on April 19 and paid the invoice on April 25.
Delivered price = $Answer:
Answer:Delivered price=$1,814
Step-by-step explanation
Explanation:
List Price = $4,000
Trade discount = 55%
Price after discount = $4,000 - 55% x $4000
$4000- $2,200 = $1,800
if Levin pays within 10 days he will have a discount of 2 %, which he did
Therefore 2% x $1800 = $36
Delivered price = $1800 -$36+ freight charges ( shipping)
$1800 -$36 + $50=$1814
What's the probability of the compound event for. A bag contains 4 red, 8 blue, 6 yellow and 2 green marbles. Maria selects a marble, puts it back and then selects a second marble. P (blue, red)
Given:
Number of red marbles = 4
Number of blue marbles = 8
Number of yellow marbles = 6
Number of green marbles = 2
To find:
The probability of getting a blue marble then a red marble, i.e., P(blue, red).
Solution:
Using the given information,
The total number of marbles = 4+8+6+2
= 20
Probability of getting a blue marble in first draw is
[tex]P(Blue)=\dfrac{\text{Number of blue marbles}}{\text{Total number of marbles}}[/tex]
[tex]P(Blue)=\dfrac{8}{20}[/tex]
[tex]P(Blue)=\dfrac{2}{5}[/tex]
Maria selects a marble, puts it back and then selects a second marble. It means the total number of marbles remains the same.
[tex]P(red)=\dfrac{\text{Number of red marbles}}{\text{Total number of marbles}}[/tex]
[tex]P(red)=\dfrac{4}{20}[/tex]
[tex]P(red)=\dfrac{1}{5}[/tex]
Now, the probability of getting a blue marble then a red marble is
[tex]P(blue,red)=\dfrac{2}{5}\times \dfrac{1}{5}[/tex]
[tex]P(blue,red)=\dfrac{2}{25}[/tex]
Therefore, the required probability P(blue, red) is [tex]\dfrac{2}{25}[/tex].
What is the multiplicative inverse of y?
Answer:
The multiplicative inverse of y is [tex]\frac{1}{y}[/tex].
Step-by-step explanation:
Multiplicative inverse implies a value that you would multiply with the given value so as to give 1.
Let the multiplicative inverse of y be represented by a, so that;
a x y = 1
ay = 1
divide both sides by y to have,
a = [tex]\frac{1}{y}[/tex]
Thus, the multiplicative inverse of y is [tex]\frac{1}{y}[/tex].
This is applicable to any given value. Examples:
i. Given 2, the multiplicative inverse is [tex]\frac{1}{2}[/tex].
⇒ 2 x [tex]\frac{1}{2}[/tex] = 1
ii. What is the multiplicative inverse of 5?
The required answer is [tex]\frac{1}{5}[/tex].
Help plz....................
In the past, 30% of a country club's members brought guests to play golf sometime during the year. Last year, the club initiated a new program designed to encourage members to bring more guests to play golf. In a sample of 95 members, 34 brought guests to play golf after the program was initiated. When testing the hypothesis that the new program has increased the proportion of members bringing out guests (using a 5% level of significance), what is the null and alternative hypothesis
Answer:
The null hypothesis, H₀: p = 0.3
The alternative hypothesis is Hₐ: p ≠ 0.3
Step-by-step explanation:
The null hypothesis, H₀, in inferential statistics is the default hypothesis that the measured quantity is zero or null and therefore there is no difference between the population characteristic measured, when the quantity measured is the difference between two situations
Therefore, the null hypothesis, H₀: p = 0.3
The alternative hypothesis is usually the opposite of the null hypothesis, therefore, the alternative hypothesis Hₐ is given as follows;
The alternative hypothesis is Hₐ: p ≠ 0.3
Identify the angles , solve for x
Answer:
Consecutive interior angles ; x = 20
Step-by-step explanation:
These are known as consecutive interior angles. This means they are equal to each other. Knowing this, we can set up an equation to solve for x.
4x - 30 = 2x + 10
2x - 30 = 10
2x = 40
x = 20

The speed of the current in a creek is 5 mph. A person clan kayak 3 mi upstream in the same time that it takes him to kayak 13 mi downstream. What is the speed
the person's kayak in still water?
The speed of the person's kayak in still water is
Answer:
8
Step-by-step explanation:
0) the basic formula is: L=v*t, where L - distance, v - speed/velocity; t - time;
1) if the person's speed in still water is 'v' and the speed of water is 5 (according to the condition), then the upstream speed is 'v-5' and the downstream speed is 'v+5';
2) according to the condition the upstream time and the downstream time are the same, it means t₁=t₂=t, where t₁=upstream time and t₂=downstream time;
3) according to the items above it is possible to make up the equation of the upstream travel: t(v-5)=3; ⇒ t=3/(v-5);
4) according to the items above it is possible to make up the equation of the downstream travel: t(v+5)=13; ⇒ t=13/(v+5);
5) if t=3/(v-5) and t=13/(v+5), then
[tex]\frac{3}{v-5} =\frac{13}{v+5}; \ => \ v=8.[/tex]
Lee el siguiente planteamiento y resuelve los problemas:
Un globo electrostáticamente cargado ejerce una fuerza de atracción sobre un papel de tal forma que se pueden identificar dos cargas positivas en la periferia del globo y una negativa en la periferia del papel. Las cargas del globo y del papel están colocadas en los vértices de un triángulo equilátero cuyos lados tienen una longitud de 5 cm, tal como se muestra en la figura. Se sabe que la carga q1 tiene polaridad negativa con un valor de 20 μC (microcoulomb), la carga q2 tiene polaridad positiva con una magnitud de 10 μC y la carga q3 también tiene polaridad positiva con una intensidad de 30 μC.
Calcula la fuerza de q3 sobre q1. Para ello, hay que sustituir los valores de las respectivas cargas en la ecuación de la ley de Coulomb y el valor de la distancia d , la cual corresponde a la separación entre q1 y q3.
Realiza el cálculo de la fuerza de q2 sobre q1.
a. Utiliza el plano cartesiano para graficar los resultados de las fuerzas solicitadas.
Determina la magnitud de la fuerza de atracción resultante que ejercen las cargas q2 y q3 sobre q1 y el ángulo del vector de la resultante.
a. Utiliza el plano cartesiano para graficar el resultado, de la magnitud de la fuerza de atracción.

- 10x + y = 4
Please help I’ve been stuck on this for an hour now PLEASEEEEE
Answer:
y= 10x + 4
Step-by-step explanation:
-10x + y = 4
-10x + y +10x = 10x + 4
y= 10x + 4
depending on what its asking usually this is what its asking for but im not sure exaclty what its asking so here.....
next step is to plug the numbers in
so for the first box it says that x is -2
plug it in.....
y = 10(-2) + 4
y = -20 + 4
y = -16
then keep doing it for the next boxes.....
second box:
y = 10(-1) + 4
y = -10 + 4
y = -6
third box:
y = 10(0) + 4
y= 4 because 10 times zero is zero (basically any number times 0 is zero)
fourth box:
y = 10(1) + 4
y = 10 + 4
y = 14
fifth box:
y = 10(2) + 4
y = 20 + 4
y = 24
Hope this helps!

Answer:
9.5
Step-by-step explanation:divide area by 12.3
i think it is right
Answer:
u= 19 miles
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Given that the area is 116.85 mi² and height= 12.3 mi,
116.85= ½ ×u ×12.3
6.15u= 116.85
u= 116.85 ÷6.15 (÷6.15 on both sides)
u= 19 mi

PLEASE HELP!! The AHS Football team did a weigh in at the start of training camp. The weights of the players were distributed normally with a mean of 98kg and a standard deviation of 6kg. Which of the following curves represents the data? A,B, Or C??
Answer: Choice C
=========================================================
Explanation:
The mean is 98, so that's the center of the distribution. This is where the highest point occurs because the most people are clustered around here. This rules out choice A and the answer is between B or C.
One standard deviation above the mean is 98+6 = 104. All we do is add on the standard deviation (6) to the mean (98) to get 104.
One standard deviation below the mean is 98-6 = 92
The graph that has tickmarks at 92 and 104 indicate we are exactly 1 standard deviation from the mean (98)
Similarly, 2 standard deviations above the mean is at 98+2*6 = 98+12 = 110. Or you could say 104+6 = 110.
2 standard deviations below the mean would get us to 98-2*6 = 98-12 = 86
The same idea applies to 3 standard deviations as well.
All of this matches with graph C. We can eliminate graph B by noticing that something like 95 is not a result of 98-6.
Apply the distributive property to create an equivalent expression. 6(3c-5d+6) = ?
Answer:
18c-30d+36
Step-by-step explanation:
6(3c-5d+6)
= 6(3c)-6(5d)+6(6)
= 18c-30d+36
