The best graphical representation for the given data would be a histogram. A histogram is a graph that displays the distribution of continuous numerical data. It consists of a series of bars, where each bar represents a range of values and the height of the bar represents the frequency or proportion of data points that fall within that range. Since the variable of interest in this case is the number of hours slept per night, which is a continuous numerical variable, a histogram would be an appropriate way to display the distribution of the data. A stem-and-leaf plot is another way to display numerical data, but it is better suited for smaller data sets. Circle graphs and bar graphs are used to display categorical data.
Marissa spent $45 on a hat and a shirt.
The hat cost $10. What is x, the cost of
the shirt in dollars? What is the answer
Answer:
To determine the cost of the shirt, we can set up an equation using algebra. Let x be the cost of the shirt in dollars. We know that Marissa spent a total of 45 on the hat and the shirt, and the hat cost 10. Therefore, we can write the equation:
x + 10 = 45
To solve for x, we need to isolate it on one side of the equation. We can do this by subtracting 10 from both sides:
x = 35
Thus, the cost of the shirt is $35.
What is the surface area of this right triangular prism?
Enter your answer in the box.

The surface area of right triangular prism of height 3 in, base 8 in, slop 5 in and width 4 in is 76 in².
What is surface area?Surface area is a measure of the total area occupied by the surfaces of a three-dimensional object.
It is the sum of the areas of all the faces, including the base(s), of the object.
The units for measuring surface area are squared units, such as square meters or square inches.
To find the surface area of a right triangular prism, we need to add the areas of all of its faces.The prism has two congruent triangular faces and three rectangular faces.
The area of every single triangle face is (1/2)bh, where b is the base of the triangle and h is its height.
In this case, the base is 8 in and the height is 5 in, so the area of each triangular face is (1/2)(8)(5) = 20 inches². Since there are two triangular faces, their combined area is 2(20) = 40 inches².
The area of each rectangular face is lw.
In this case, the width is 4 in and the height is 3 in, so the area of each rectangular face is (4)(3) = 12 inches². Since there are three rectangular faces, their combined area is 3(12) = 36 inches²
Therefore, the total surface area of the right triangular prism is the sum of the areas of all its faces:
Surface area = 2(triangular face area) + 3(rectangular face area)
Surface area = 2(20) + 3(12)
Surface area = 40 + 36
Surface area = 76 inches²

The equation [tex]p^{2} =5a[/tex] represents the perimeter, p, of a square with an area, A, a square stained glass had an area of 20ft. What is the perimenter of the window?
The area of the stained glass is given as 20ft².
Let's start by finding the length of one side of the square stained glass. Since the area of a square is given by the formula A = s^2, where s is the length of one side of the square, we have:
s^2 = A
s^2 = 20ft²
s = sqrt(20)ft
s = 2sqrt(5)ft
Now, we can use the given equation p^2 = 5A to find the perimeter p of the square, by substituting the value of A:
p^2 = 5A
p^2 = 5(20ft²)
p^2 = 100ft²
p = sqrt(100ft²)
p = 10ft
Therefore, the perimeter of the square stained glass is 10 feet.

2. Tammi has a bowl of fruit which has only apples and bananas. The ratio is 2 apples to each banana. If there are a total of 15 fruits in the bowl, how many apples are there?
there are 200 green balloons, there are 120 red balloons , there are 10 apples and 5 bananas in the bowl, for a total of 15 fruits. To solve this problem, we need to use the given ratio and the total number of balloons to find the number of green balloons.
Let's assume the number of green balloons is x. Then, the number of red balloons is 3/5 of x, or (3/5)x.
The total number of balloons is 320, so we can write an equation based on the given information:
x + (3/5)x = 320
To solve for x, we can simplify the equation:
(8/5)x = 320
x = 200
Therefore, there are 200 green balloons.
To check our answer, we can use the ratio given in the problem:
(3/5)x = (3/5) * 200 = 120
So there are 120 red balloons.

The total number of fruits in the bowl is 15, so we can write an equation based on the given information:
x + 2x = 15
To solve for x, we can simplify the equation:
3x = 15
x = 5
Therefore, there are 5 bananas in the bowl.
To find the number of apples, we can use the ratio given in the problem:
2x = 2 * 5 = 10
So there are 10 apples in the bowl.

a university's administrator proposes to do an analysis of the proportion of graduates who have not found employment in their major field one year after graduation. in previous years, the percentage averaged 13%. he wants the margin of error to be within 4% at a 99% confidence level. what sample size will suffice?
To have a margin of error within 4% at a 99% confidence level, a sample size of at least 469 graduates is needed for the administrator's analysis of the proportion of graduates who have not found employment in their major field one year after graduation.
To determine the sample size needed for the administrator's analysis, we can use the formula:
n = (Z^2 * p * (1 - p)) / E^2
where:
n = sample size needed
Z = the Z-score corresponding to the desired confidence level (99% corresponds to a Z-score of approximately 2.576)
p = the expected proportion of graduates who have not found employment in their major field (13%, or 0.13)
E = the desired margin of error (4%, or 0.04)
Substituting the given values into the formula, we get:
n = (2.576^2 * 0.13 * (1 - 0.13)) / 0.04^2
Simplifying and solving for n, we get:
n ≈ 468.42
Rounding up to the nearest whole number, we get:
n = 469
Therefore, a sample size of at least 469 graduates is needed for the administrator's analysis to have a margin of error within 4% at a 99% confidence level.

El valor de las razones trigonométricas no depende del tamaño del triángulo sino de la medida del ángulo ¿ es verdad o falso ? argumenten su respuestas
Answer: Falso. Las razones trigonométricas dependen tanto del tamaño del triángulo como de la medida del ángulo. Esto se debe a que las razones trigonométricas de un triángulo se calculan relacionando los lados del triángulo con el ángulo. Por lo tanto, si cambia el tamaño del triángulo, los lados cambiarán y, por consiguiente, las razones trigonométricas también cambiarán.
Step-by-step explanation:
Consider the parametric curve x = 4t 3 − 3t, y = t 5 − 5t, t ∈ R. (a) Find the points where the tangent line is horizontal or vertical. (b) Determine the intervals where the slope of the tangent line to the curve is positive or negative. (c) Determine the intervals where the curve is concave upward or downward. (d) Sketch the curve.
The points where the tangent line is vertical are (13/16, -5/16) and (-13/16, 5/16) and The slope of the tangent line is positive on the intervals t < -1 and t > 1, and negative on the interval -1 < t < 1.
How can we analyzing the properties of a parametric curve?(a) To find where the tangent line is horizontal, we need to find values of t where the derivative of y with respect to x (dy/dx) is equal to 0.
We have:
dy/dx = (dy/dt)/(dx/dt) = (5t^4 - 5)/(12t^2 - 3)
Setting dy/dx = 0, we get:
5t^4 - 5 = 0
t^4 = 1
t = ±1 or t = ±i
Substituting t = 1 into the parametric equations gives us the point (1,-4). Substituting t = -1 gives us the point (-1,4). Substituting t = i or t = -i gives us points on the imaginary axis, which are not part of the real plane.
Therefore, the points where the tangent line is horizontal are (1,-4) and (-1,4).
To find where the tangent line is vertical, we need to find values of t where dx/dt is equal to 0.
We have:
dx/dt = 12t^2 - 3
Setting dx/dt = 0, we get:
t^2 = 1/4
t = ±1/2
Substituting t = 1/2 into the parametric equations gives us the point (13/16, -5/16). Substituting t = -1/2 gives us the point (-13/16, 5/16).
Therefore, the points where the tangent line is vertical are (13/16, -5/16) and (-13/16, 5/16).
(b) To determine the intervals where the slope of the tangent line is positive or negative, we need to examine the sign of the derivative dy/dx.
From part (a), we know that dy/dx is equal to:
dy/dx = (5t^4 - 5)/(12t^2 - 3)
The denominator is always positive, so the sign of dy/dx is determined by the numerator.
For t < -1, we have 5t^4 - 5 > 0, so dy/dx > 0.
For -1 < t < 1, we have 5t^4 - 5 < 0, so dy/dx < 0.
For t > 1, we have 5t^4 - 5 > 0, so dy/dx > 0.
Therefore, the slope of the tangent line is positive on the intervals t < -1 and t > 1, and negative on the interval -1 < t < 1.
(c) To determine the intervals where the curve is concave upward or downward, we need to examine the sign of the second derivative d^2y/dx^2.
We have:
d^2y/dx^2 = ((d^2y/dt^2)(dx/dt) - (dy/dt)(d^2x/dt^2)) / (dx/dt)^3
Calculating the second derivatives, we get:
d^2y/dt^2 = 20t^3
d^2x/dt^2 = 24t
Substituting these into the expression for d^2y/dx^2, we get:
d^2y/dx^2 = (20t^3)(12t^2 - 3) - (5t^4 - 5)(24t) / (12t^2 - 3)^3
Simplifying this expression, we get:

Answer:
X = 34, Y=56
Step-by-step explanation:
BOA is an isosceles triangle.
Angle CBO = 90°
Angle DBO = 90 - 56 = 34
Angle ODB = 34° and ODB is x
Angle EBD is also 90°
Y = 180 - (90+34) = 56
The value of x is 34 degree and y is 56 degree.
What is a Tangent?Tangents to circles are lines that cross the circle at a single point. Point of tangency refers to the location where a tangent and a circle converge. The circle's radius, where the tangent intersects it, is perpendicular to the tangent. Any curved form can be considered a tangent.
We have, BOA is an isosceles triangle.
< CBO = 90°
So, < DBO = 90 - 56
<DBO = 34
and, <ODB = 34°
Now, let the angle ODB be x

a local paint company surveyed people and found that 53% prefer brand a paint. a sample of 6 was taken. what is the probability that at least 1 person prefers brand a paint?
By using the complement probability that none of the 6 people prefer brand A paint, the probability that at least 1 person in a sample of 6 prefers brand A paint is 0.9939 or approximately 99.39%.
To find the probability that at least 1 person in the sample of 6 prefers brand A paint, we need to find the probability of the complement event that none of the 6 people prefer brand A paint, and subtract it from 1.
The probability that one person prefers brand A paint is 0.53, and the probability that one person does not prefer brand A paint is 0.47. Since we are dealing with a binomial distribution, we can use the formula for the probability of k successes in n trials:
P(k successes) = n! / (k! * (n - k)!) * p^k * (1 - p)^(n - k)
Using this formula, we can calculate the probability of 0 people preferring brand A paint:
P(0 people prefer brand A) = 6! / (0! * 6!) * 0.53^0 * 0.47^6 = 0.0061
Therefore, the probability of at least 1 person preferring brand A paint is:
P(at least 1 person prefers brand A) = 1 - P(0 people prefer brand A) = 1 - 0.0061 = 0.9939
So, the probability that at least 1 person prefers brand A paint is 0.9939 or approximately 99.39%.

The fraction of vehicles on the road are trucks is 3/7
Let's assume there are a total of x vehicles on the road.
According to the first statement, 3/7 of those vehicles are trucks followed by a car. This means that (3/7)x trucks are on the road and are followed by a car.
According to the second statement, 3/9 of the vehicles are cars followed by a truck. This means that (3/9)x cars are on the road and are followed by a truck.

(27/63)x + (21/63)x = x
(48/63)x = x
We can then solve for x
x = 63
So there are 63 vehicles on the road.
To find out what fraction of vehicles on the road are trucks, we need to determine what fraction of those 63 vehicles are trucks.

Answer: $10,00; $15,00 and $20,00
First, let’s mark the streaming platforms as letters x, y, z:
x - Disney +
y - Netflix
z - Hulu
Each platform costs $540,00 per year, so that would be $540,00/12=$45,00 per month
Since we know that Disney + and Hulu per year cost $300,00 and all three platforms cost $540,00 per year, we can find how much does Netflix cost per year:
$540,00-$300,00 = $240,00
Per month: $240,00/12 = $20,00
Now we can write equations according to the given information:
y = 2x
x+y+z = 540,00
x+z = 300,00
We can find how much does Disney + cost per year from the first equation, since we already know the price of Netflix per year:
2x = 240,00 / : 2
x = 120,00 (per year)
Per month: $120,00/12 = $10,00
And finally, since we know that all three platforms cost $45,00 per month, we can find the price of Hulu per month:
$45,00 - $20,00 - $10,00 = $15,00
So, Netflix costs $20,00 per month, Disney + - $10,00 per month and Hulu - $15,00 per month
What is the answer to this question? If m angle J +(7x+13) , mangleK = (83-2x) and the sum of the measures of the angle is 141 degrees find the measure of each angle>
The expression has basic mathematical operators. is The measurement of the two angles ∠J and ∠K is 76° and 65° respectively.
What is Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given to us
∠J = (7x + 13)°,
∠K = (83 - 2x)°,
the sum of the two angles is 141°.
As it is given that the sum of the two angles is 141°, therefore, the expression for the sum of the two angles can be written as,
∠J + ∠K = 141°
(7x + 13)° + (83 - 2x)° = 141°
7x + 13 +83 - 2x = 141
5x = 141 - 83 - 13
5x = 45
x = 9
Now, we got the value of x, substitute the value of x in given measurements, therefore,
∠J = (7x + 13)°
∠J = 7(9) + 13
∠J = 63 + 13
∠J = 76°
∠K = (83 - 2x)°
∠K = (83 - 2(9))°
∠K = (83 - 18)°
∠K = 65°
Hence, the measurement of the two angles ∠J and ∠K is 76° and 65° respectively.
