Tv emporium had a huge sale in the morning 5/12 of the flat screen televisions were sold in the afternoon one-third of the flat screen televisions were sold how many flat screen televisions were sold all together
Answer:
Total number of flat screen sold is 3/4
Step-by-step explanation:
Let the total number of the flat screen sold be y
y = number of flat screen sold in the morning + number of the flat screen sold in the afternoon.
Number sold in the morning = 5/15
Number sold in the afternoon = 1/3
Y = 5/12 + 1/3
Find the LCM of 12 and 3
Y = (5 + 4)/12
Y = 9/12
Y = 3/4
Total number of flat screen sold is 3/4

A jar contains 11 green marbles, 7 red marbles, and 6 blue marbles. A marble is selected at random, not replaced, and then a second marble is selected. What is the probability of selecting a blue marble followed by a green marble?
Write In a fraction.
Answer:
11/92
Step-by-step explanation:
G = 11
R = 7
B = 6
P(b) = 6/24 = 1/4
P(g) = 11/23
P(blue first and then green(without replacement)) = 1/4 * 11/23
= 11/92
The probability of randomly selecting a blue marble followed by a green marble from a jar of 24 marbles (6 blue, 7 red, 11 green) is 11/92.
Explanation:The number of outcomes considered favorable or desired is compared to the total number of outcomes possible. In this situation, we're interested in choosing a blue marble first, then a green marble. The total number of marbles is 11 green + 7 red + 6 blue = 24 marbles.
Initially, the probability of selecting a blue marble is 6/24 = 1/4
because there are 6 blue marbles out of a total of 24.
After taking one marble out (assuming it's blue), you have 23 marbles left, with 11 of them being green. So, the probability of selecting a green marble next is 11/23.
Therefore, the probability of both of these events happening (selecting a blue marble followed by a green marble) is found by multiplying these two probabilities together, which gives (1/4) * (11/23) = 11/92.

Kenneth measured a hotel and made a scale drawing the scale he used was 1 inch= 4 feet the actual length of a room in the hotel is 20 feel how long is the room in the drawing
Answer:
The length of the room in the drawing is 5 inches.
Step-by-step explanation:
Given:
Kenneth measured a hotel and made a scale drawing the scale he used was 1 inch= 4 feet.
The actual length of a room in the hotel is 20 feet.
Now, to find the length of the room in the drawing.
Let the length of the room in the drawing be [tex]x.[/tex]
The actual length of the room = 20 feet.
The scale used in drawing is 1 inch = 4 feet.
As, 1 inch is equivalent to 4 feet.
Thus, [tex]x[/tex] is equivalent to 20 feet.
Now, to get the length of the room in the drawing we use cross multiplication method:
[tex]\frac{1}{4} =\frac{x}{20}[/tex]
By cross multiplying we get:
[tex]20=4x[/tex]
Dividing both sides by 4 we get:
[tex]5=x[/tex]
[tex]x=5\ inches.[/tex]
Therefore, the length of the room in the drawing is 5 inches.

The sum of two numbers is 29
and their product is 180.
Find the numbers.
Final answer:
To find the two numbers with a sum of 29 and product of 180, we set up a system of equations, solve for one variable in terms of the other, and then factor a quadratic equation to find that the two numbers are 20 and 9.
Explanation:
The student's question is about finding two numbers based on their sum and product. To solve this, we can set up two equations based on the given information: let's call our numbers x and y. The first equation based on their sum is x + y = 29, and the second equation based on their product is xy = 180.
We can find one number in terms of the other using the first equation: y = 29 - x. We then substitute this into the second equation to get x(29-x) = 180. Simplifying, we have x² - 29x + 180 = 0. Factoring the quadratic equation, we get (x - 20)(x - 9) = 0, which gives us two possible values for x: 20 or 9. Thus, the two numbers are 20 and 9.

If six cookies cost the same as 2 brownies, and four brownies cost the same as 10 cupcakes, how many cupcakes can Bob buy for the price of eighteen cookies?
Bob can buy 15 cupcakes for the price of 18 cookies.
Step-by-step explanation:
Assume the cost of a cookie is $x, the cost of a brownie is $y and the cost of a cupcake is $z.It is given that 6 cookies and 2 brownies cost the same, so 6x = 2y, take this as equation 1.It is also given that 4 brownies cost the same as 10 cupcakes, so 4y = 10z, take this as equation 2.If we divide equation 2 by 2 we get, 2y = 5z so that the y value is the same as equation 1 and we can equate equation 1 and 3.We get 6x = 2y = 5z, 6x = 5z, dividing both sides by 5, we get 1.2x = z.We need to calculate how many cupcakes Bob can buy for the price of 18 cookies, So we must find the z value when the x = 18.If we multiply 1.2 with 15 we get 18 so we the last equation is multiplied with 12 so that 18x = 15z. 18 cookies and 15 cupcakes cost the same.Right △EFG has its right angle at G, EF=8 , and FG=6 .
What is the value of the trigonometric ratio of an angle of the triangle?
Drag a value to each box to match the trigonometric ratio with its value.
Answer:
[tex]sec\ E = \frac{4\sqrt{7} }{7}[/tex]
[tex]Cos\ F = \frac{3}{4}[/tex]
[tex]Tan\ F =\frac{\sqrt{7}}{3}[/tex]
Step-by-step explanation:
Given
EF = 8
FG = 6
We need to find the trigonometric ratios.
Solution:
First we will find the length of the third side.
Now we know that;
△EFG is a right angled triangle with right angle at G.
Now applying Pythagoras theorem which states.
"The sum of square of the two legs of the triangle is equal to square of the hypotenuse."
so we can say that;
[tex]FG^2=EF^2+EG^2\\\\EG^2=FG^2-EF^2[/tex]
Substituting the given values we get;
[tex]EG^2=8^2-6^2=64-36=28[/tex]
Taking square roots on both side we get;
[tex]\sqrt{EG^2} =\sqrt{28}=\sqrt{4\times7}\\ \\EG = 2\sqrt{7}[/tex]
Now we will find the trigonometric values.
[tex]secE=\frac{Hypotenuse}{Adjacent\ side}[/tex]
Here Hypotenuse = EF = 8
Adjacent side of E = EG = [tex]2\sqrt{7}[/tex]
[tex]secE=\frac{8}{2\sqrt{7}} =\frac{4}{\sqrt{7}}[/tex]
Now rationalizing the denominator by multiplying numerator and denominator by [tex]\sqrt{7}[/tex] we get;
[tex]secE=\frac{4\times \sqrt{7} }{\sqrt{7}\times \sqrt{7} }\\\\secE = \frac{4\sqrt{7} }{7}[/tex]
Now,
[tex]Cos F = \frac{Adjacent \ side}{Hypotenuse}[/tex]
Adjacent side to F =GF = 6
Hypotenuse = EF = 8
[tex]Cos\ F = \frac{6}{8}\\\\Cos\ F = \frac{3}{4}[/tex]
Now,
[tex]Tan F = \frac{opposite \ side}{adjacent\ side}[/tex]
Here Opposite side of F = EG = [tex]2\sqrt{7}[/tex]
Adjacent side of F = GF = 6
[tex]Tan\ F= \frac{2\sqrt{7}}{6}\\\\Tan\ F =\frac{\sqrt{7}}{3}[/tex]
Hence Below are required details.
[tex]sec\ E = \frac{4\sqrt{7} }{7}[/tex]
[tex]Cos\ F = \frac{3}{4}[/tex]
[tex]Tan\ F =\frac{\sqrt{7}}{3}[/tex]
The value of the trigonometric ratio of an angle of the triangle is;
[tex]\rm SecE=\dfrac{8}{2\sqrt{7}}=\dfrac{4}{\sqrt{7} }\\\\CosF = \dfrac{6}{8}=\dfrac{3}{4}\\\\Tan F =\dfrac{2\sqrt{7}}{3}=\dfrac{\sqrt{7} }{3}\\[/tex]
Given
Right △EFG has its right angle at G, EF=8, and FG=6.
Pythagoras theoremThe Pythagoras theorem states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of the other two sides of the right-angled triangle.
In right-angle △EFG, in which E is a right angle.
[tex]\rm EF^2=FG^2-EG^2\\\\8^2=6^2-EG^2\\\\EG^2=8^2-6^2\\ \\EG^2=64-36\\\\EG^2=28\\\\EG = 2\sqrt{7}[/tex]
The value of the trigonometric ratio of an angle of the triangle is;
[tex]\rm SecE=\dfrac{8}{2\sqrt{7}}=\dfrac{4}{\sqrt{7} }\\\\CosF = \dfrac{6}{8}=\dfrac{3}{4}\\\\Tan F =\dfrac{2\sqrt{7}}{3}=\dfrac{\sqrt{7} }{3}\\[/tex]

A warehouse worker ships 25 boxes each day. Every box contains 3 shipping labels. Inventory has 500 shipping labels. How many days will it take to use the inventory of shipping labels? round to the nearest whole.
Answer: It will take 7 days to use the inventory of shipping labels.
Step-by-step explanation:
Given : Total boxes shipped by warehouse worker per day = 25
Every box contains 3 shipping labels.
Inventory has 500 shipping labels.
Then, the total number of boxes can be made = (Total shipping labels) ÷ (labels in each box)
500 ÷ 3 =166.67≈166
Number of days it will take to use the inventory of shipping labels= (total number of boxes can be made) ÷ (Total boxes shipped per day)
= 166÷ 25=6.64≈7
Hence, it will take 7 days to use the inventory of shipping labels.
It will take about 7 days to use the inventory of shipping labels.
Explanation:To find how many days it will take to use the inventory of shipping labels, we need to divide the total number of shipping labels by the number of shipping labels used per day.
The total number of shipping labels is 500 and the worker ships 25 boxes each day, with each box containing 3 shipping labels.
So, the worker uses 25 x 3 = 75 shipping labels per day.
Dividing the total number of shipping labels (500) by the number of shipping labels used per day (75), we get 500 / 75 = 6.67.
Rounding to the nearest whole number, it will take about 7 days to use the inventory of shipping labels.

A researcher records the family relationship (brother, son, father, cousin, etc.) of the
people who stay in regular contact with loved ones in a nursing home. What type of measure
is family relationship?
A) Quantitative and discrete
B) Qualitative and discrete
C) Qualitative and continuous
D) Quantitative and continuous
Answer:
The correct option is B) Qualitative and discrete.
Step-by-step explanation:
Consider the provided information.
Quantitative variable is the variables that can be determined by counting or measuring something.
Qualitative variable is the variables that can't be determined by counting or measuring something.
If the value is obtained by counting then it is called discrete variable, If the value obtained by measuring then it is called continuous variable.
Since the relationship can't be measure by counting so it it qualitative variable.
We can calculate the regular contact days so it is discrete variable.
Therefore, the correct option is B) Qualitative and discrete.

At [tex]x=3,y=72[/tex]
Now, for a proportional relationship, the constant of proportionality is given as the ratio of the two values of the two variables that are in proportion.
Here, 'x' and 'y' are in proportion. So, the constant of proportionality is given as:
[tex]k=\frac{y}{x}\\\\k=\frac{72}{3}=24[/tex]
Therefore, the constant of proportionality is 24.
Now, a proportional relationship in 'x' and 'y' is given as:
[tex]y=kx[/tex]
Now, plug in the given value of 'k' and complete the equation. This gives,
[tex]y=24x[/tex]
Therefore, the equation that relates 'x' and 'y' is [tex]y=24x[/tex]
How do you do this problem?
Answer:
A) g is increasing, and the graph of g is concave up.
Step-by-step explanation:
g'(x) = ∫₀ˣ e^(-t³) dt
Since e^(-t³) is always positive, ∫₀ˣ e^(-t³) dt is positive when x > 0. So the function is increasing.
Find g"(x) by taking the derivative using second fundamental theorem of calculus:
g"(x) = e^(-x³)
g"(x) is always positive, so the function is always concave up.
A baker started out with 13 cups of flour.She had 9 and 1 four cups of flour left after the first batch of batter she made.She have 6 and 1 half cups of flour left after the second batch of batter she made.If she makes two more batches of batter,how many cups of flour will be left?
Question is wrong; Correct question is given below;
A baker started out with 12 cups of flour she had 9 1/4 cups of flour left after the first bunch of batter she made she had 6 1/2 cups of flour left after the second bunch of batter she made if she makes two more batches of batter how many cups of batter will be left?
Answer:
Baker will be left with 1 cups of Flour.
Step-by-step explanation:
Given
Amount of flour baker started with = 12 cups
Amount of flour left after making first batter = [tex]9\frac14\ cups[/tex]
[tex]9\frac14\ cups[/tex] can be Rewritten as [tex]\frac{37}4\ cups[/tex]
Amount of flour left after making first batter = [tex]\frac{37}4\ cups[/tex]
Now we can say that;
Amount of flour used to make first batter is equal to Amount of flour baker started with minus Amount of flour left after making first batter
Thus, the Amount of flour she use to make first batter = [tex]20-\frac{37}{4}[/tex]
Now we will use LCM to make the denominator common we get;
Amount of flour she use to make first batter = [tex]\frac{20\times4}{4}-\frac{37\times1}{4\times1} = \frac{48}{4}-\frac{37}{4}[/tex]
Now denominator common so we will solve the numerator we get;
Amount of flour she use to make first batter = [tex]\frac{48-37}{4}=\frac{11}{4}\ cups.[/tex]
Now Given:
Amount of flour left after the second batch of batter = [tex]6\frac12\ cups[/tex]
[tex]6\frac12\ cups[/tex] can be Rewritten as [tex]\frac{13}2\ cups[/tex]
Amount of flour left after the second batch of batter = [tex]\frac{13}2\ cups[/tex]
Thus, the quantity she use to make second batter = [tex]\frac{37}{4}-\frac{13}{2}[/tex]
Now we will use LCM to make the denominator common we get;
Amount of flour she use to make Second batter = [tex]\frac{37\times1}{4\times1}-\frac{13\times2}{2\times2}=\frac{37}{4}-\frac{26}{4}[/tex]
Now denominator common so we will solve the numerator we get;
Amount of flour she use to make Second batter = [tex]\frac{37-26}{4}=\frac{11}{4}\ cups[/tex]
Thus, she use [tex]\frac{11}{4}\ cups[/tex] of flour for each batter.
Amount of Flour used in making 2 more batter = [tex]2\times\frac{11}{4}= \frac{11}{2}\ cups[/tex]
Now we can say that;
Cups of flour left will be equal to Amount of flour left after the second batch of batter minus Amount of Flour used in making 2 more batter.
framing in equation form we get;
Cups of flour left = [tex]\frac{13}{2}-\frac{11}{2}=\frac{13-11}{2}=\frac{2}{2}=1\ cup[/tex]
Hence Baker will be left with 1 cups of Flour.
To determine customer opinion of their safety features, Daimler - Chrysler randomly selects 110 service centers during a certain week and surveys all customers visiting the service centers. What type of sampling is used? a.Simple b.random c.Convenience d.Cluster e.Systematic f.Stratified
Simple sampling - A method where individuals are chosen randomly from a larger set.
Convenience sampling - The sample is being chosen as per ease of access thus it is not a random sampling.
Systematic sampling - Probability method where elements are chosen from a target population.
Stratified sampling - Method where population were divided into different groups called strata and the sample is then drawn from each group.
Cluster sampling - Population is where population were divided into different groups known as clusters. The clusters were then chosen randomly as the samples.
Answer: D (cluster sampling) - The service centers refer as the clusters and it is chosen randomly.
Final answer:
The Daimler - Chrysler survey method is an example of cluster sampling, where random groups (service centers) are selected and all members within these groups are surveyed.
Explanation:
The type of sampling used by Daimler - Chrysler when they randomly select 110 service centers during a certain week and survey all customers visiting those service centers is cluster sampling. In cluster sampling, the overall population is divided into groups, or clusters, and a random selection of these clusters is chosen.
All members (or customers, in this case) within these selected clusters are surveyed. This method is often more practical and cost-effective than surveying the entire population. It is important that the clusters themselves are representative of the population to ensure that data obtained is not biased.
Alden paid to have some programs printed for the football game last weekend. The printing cost per program was 54 cents, and the plan was to sell them for 75 cents each. Poor weather kept many fans away from the game, however, so unlucky Alden was left with 100 unsold copies, and lost $12 on the venture. How many programs did Alden have printed?
Answer:
300 programs
Step-by-step explanation:
Let’s work with cents to make this easier. We convert the $12 to cents, making 1200 cents
Let the number of copies Alden printed be x. His total printing cost would be x * 54 = 54x cents.
He sold at 75 cents each and still had left 100 copies. This means his total sale would be (x - 100)75
He lost $12 on the venture. This means his cost price minus his selling price is $12 since it’s a loss.
Computing this:
54x - 75(x - 100) = 1200
54x - 75x + 7500 = 1200
-21x = 1200 - 7500
-21x = -6,300
x = 6300/21 = 300 programs
