The histogram shows the number of points scored by a basketball team for one season. A histogram titled points scored in one season shows the number of games in which a certain number of points were scored. The data is as follows. 69 to 76 points: 3 games. 77 to 84 points: 6 games. 85 to 92 points: 8 games. 93 to 100 points: 1 game. According to the histogram, in what percentage of games did the team score between 77 and 92 points? Enter your answer in the box. Round your answer to the nearest percent.
Answers
Find the total number of games with points scored between 77 & 92 pts - 14
To find the percentage divide 14/18 - .777
Multiply .777*100 - 77.7
Round to 78%
Percentage of games the team scored between 77 and 92 is 77.7% .
Given data from the histogram shows the number of games that are played in the range of 77 - 92.
Total number of games played = 18
Number of games played in the range 77 - 92 = 14
Percentage of games played in the range 77-92 = (Number of games played in the range 77 - 92) / (Total number of games played) × 100
Percentage = (14)/(18) × 100
= 77.7% .
Hence the number of games played in the given range is 77.7%.

Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G

A right triangle is drawn on graph paper. The length of the legs measure 1.5 centimeters and 2 centimeters. The length of the hypotenuse measures 2.5 centimeters. Write an equation using the triangle’s side lengths to show the Pythagorean Theorem holds true for the triangle.
Answers
The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
In this case, let's denote the lengths of the legs as a = 1.5 centimeters and b = 2 centimeters, and the length of the hypotenuse as c = 2.5 centimeters.
The equation using the triangle's side lengths to show the Pythagorean Theorem holds true for the triangle is:
a^2 + b^2 = c^2
Substituting the given values, we have:
(1.5)^2 + (2)^2 = (2.5)^2
2.25 + 4 = 6.25
6.25 = 6.25
Therefore, the equation holds true, confirming that the Pythagorean Theorem is satisfied for the given right triangle.

Error Analysis: A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing $6 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Part 1: The correct selling price is (Round to the nearest dollar as needed.)
Part 2: What was the manager's likely error?
A. The manager set the selling price at the markup.
B. The manager subtracted the markup from the cost instead of adding it.
C. The manager set the selling price at the cost.
D. The manager added the markup to the cost instead of subtracting it.
Answers
Answer:
To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.
Therefore, the correct selling price is $4.
The manager's likely error was that they set the selling price at the cost (option C).
Step-by-step explanation:
The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Cost of item = $6
Markup = 67%
67% of $6 ⇒ 0.67 x 6 = $4.02
Add the markup in the cost = $6 + $4.02 = $10.02
Round to nearest dollars = $10.2 ≈ $10.
The manager put $4 which is a markup instant of the selling price of $10.
Hence "The correct selling price is $10 and the manager set the selling price at the markup".

state the vertices, foci, and asymptotes of the hyperbola with the equation
20x^2-25y^2=100
PLEASE SHOW YOUR WORK SO I CAN UDERSTAND!!!
Answers
(x^2)/(5) - (y^2)/(4) = 1
From this equation, we can see that the hyperbola has a horizontal transverse axis, since the x^2 term is positive and is divided by a smaller number than the y^2 term. Therefore, the center of the hyperbola is (0,0).
Using the standard form of the hyperbola, we can find the values of a and b:
a^2 = 5, so a = sqrt(5)
b^2 = 4, so b = 2
Now we can find the vertices, foci, and asymptotes:
Vertices:
The vertices are located at (±a,0), so the vertices are at (-sqrt(5),0) and (sqrt(5),0).
Foci:
The foci are located at (±c,0), where c = sqrt(a^2 + b^2). Plugging in our values of a and b, we get:
c = sqrt(5+4) = sqrt(9) = 3
So the foci are at (-3,0) and (3,0).
Asymptotes:
The equations of the asymptotes are y = ±(b/a)x, so the equations of the asymptotes are:
y = ±(2/sqrt(5))x
Therefore, the vertices are (-sqrt(5),0) and (sqrt(5),0), the foci are (-3,0) and (3,0), and the equations of the asymptotes are y = ±(2/sqrt(5))x.

a train passes through an intersection at the rate of 3 cars per 30 seconds. Assume that it takes 5 minutes for the train to completely pass through the intersection. How many cars does the train have all together
Answers
Answer:
30
Step-by-step explanation:
To answer this question, we need to figure out the amount of cars that the train has. The info we have is that the train is moving at 3 cars every 30 seconds. To make this easier to solve, we can multiply the rate by 2 to get the minutely rate, which is 6 cars per minutes. Then you multiply 6 by 5 and you get 30 cars on the train.
The area of triangle ABD is 50cm, and one of its sides is 10cm in length. Find one of the heights of the triangle.
Answers
Answer:
10cm
Step-by-step explanation:
If you want to find one of the heights of the triangle, you need to use some math magic. The magic spell is:
A = (1/2) * b * h
where A is the area, b is the base, and h is the height. Don't ask me why, it just works.
Now, we know that the area of triangle ABD is 50 cm and one of its sides is 10 cm. We can pretend that this side is the base of the triangle. Why? Because it makes our life easier. Trust me.
Then we put these numbers into the magic spell and we get:
50 = (1/2) * 10 * h
Now we need to solve for h, which is the height we want. To do that, we need to do some algebra. Don't worry, it's not that hard. Just follow these steps:
- Multiply both sides by 2. This gives us:
100 = 10 * h
- Divide both sides by 10. This gives us:
10 = h
- Celebrate! We found the height!
So, one of the heights of the triangle is 10 cm. Isn't math fun?
Area of triangle = 1/2 × base × height
We know the area of the triangle is 50 cm², and one of the sides (which is also the base) is 10 cm. Let's substitute these values in the formula and solve for the height:
50 = 1/2 × 10 × height
Multiplying both sides by 2, we get:
100 = 10 × height
Dividing both sides by 10, we get:
height = 10 cm
Therefore, the height of triangle ABD is 10 cm.
