Answer:
c) 27 percent, 36 percent, 37 percent
Step-by-step explanation:
Given,
Hot dogs sold by,
Vendor a = 456
Vendor b = 607
Vendor c = 637,
Total hot dogs = 1700,
Thus, the percentage of the hot dogs sold by a = [tex]\frac{\text{Hot dog sold by a}}{\text{Total hot dogs}}\times 100[/tex]
[tex]=\frac{456}{1700}\times 100[/tex]
[tex]=\frac{456}{17}[/tex]
= 26.82%
≈ 27%
Similarly,
Percentage of the hot dogs sold by a
[tex]=\frac{607}{1700}\times 100[/tex]
[tex]=\frac{607}{17}[/tex]
= 35.71%
≈ 36%
Percentage of the hot dogs sold by a
[tex]=\frac{637}{1700}\times 100[/tex]
[tex]=\frac{637}{17}[/tex]
= 37.47%
≈ 37%
Hence, OPTION c) is correct.

Find the total area of the regular pyramid.
Answer:
Area of the regular pyramid = 16.64 square units.
Step-by-step explanation:
Given : Regular pyramid .
To find: Find the total area of the regular pyramid.
Solution : We have given that regular pyramid.
Area = 4 ( area of triangle ) + area of base .
Area of the regular pyramid = 4 ( [tex]\frac{1}{2} * base * height + side * side[/tex].
Area of the regular pyramid = [tex]4(\frac{1}{2}* 2* \sqrt{10} + 2*2[/tex]
Area of the regular pyramid = [tex]4( \sqrt{10} ) + 4[/tex]
Area of the regular pyramid = (4 [tex]( \sqrt{10} ) \+\ 1[/tex].
Area of the regular pyramid = 16.64 square units.
Therefore, Area of the regular pyramid = 16.64 square units.

a. 95% of all gallup poll samples like this one give answers within ±3% of the true population value.
b. the percent of the population who jog is certain to be between 15% and 21%.
c. 95% of the population jog between 15% and 21% of the time.
d. we can be 3% confident that the sample result is true.
e. if gallup took many samples, 95% of them would find that exactly 18% of the people in the sample jog.
Final answer:
The ±3 percent represents the margin of error in the Gallup poll, indicating the potential variation in the poll results due to sampling. The percentage of people who jog regularly could be as low as 15% or as high as 21%.
Explanation:
The ±3 percent represents the margin of error in the Gallup poll. The margin of error is a measure of the uncertainty or potential variation in the poll results due to the sampling process. In this case, it means that the percentage of people who say they jog regularly could be as low as 15% or as high as 21%.

Larry's lemons is a street vendor business that sells lemonade and lemon bars. A cup of lemonade sells for $2 and a lemon bar sells for $1.50. When all related business expenses are included, a cup of lemonade costs $0.25 to prepare and a lemon bar costs $0.20 to prepare. Last Monday, one of the vendors selling Larry's Lemons sold at least $500 worth of lemonade and lemon bars and its expenses were no more than $100. At least 150 cups of lemonade were sold. Let x be the number of cups of lemonade sold last Monday and y be the number of lemon bars sold last Monday. Which ordered pair representing a combination of cups of lemonade and lemon bars could have been sold last Monday and make sense in the context of the situation?
The one possible ordered pair that satisfies all conditions is (x, y) = (150, 134).
The ordered pair (x, y) that satisfies the following conditions:
1. The total revenue from selling x cups of lemonade and y lemon bars is at least $500. This gives us the inequality:
[tex]\[ 2x + 1.50y \geq 500 \][/tex]
2. The total expenses for preparing x cups of lemonade and y lemon bars is no more than $100. This gives us the inequality:
[tex]\[ 0.25x + 0.20y \leq 100 \][/tex]
3. At least 150 cups of lemonade were sold, which gives us the inequality:
[tex]\[ x \geq 150 \][/tex]
To find a combination of x and y that satisfies all these conditions, we can start by considering the minimum number of lemonade cups sold, which is 150. We can then calculate the revenue and expenses for this minimum number and see how many lemon bars would be needed to meet the revenue requirement while keeping the expenses within the limit.
Let's start with the minimum number of lemonade cups:
[tex]\[ x = 150 \][/tex]
The revenue from lemonade alone would be:
[tex]\[ 2 \times 150 = \$300 \][/tex]
The expenses for lemonade alone would be:
[tex]\[ 0.25 \times 150 = \$37.50 \][/tex]
Now, we need to find out how many lemon bars (y) would be needed to make up the remaining revenue to at least $500 while keeping the total expenses at or below $100.
Let's denote the remaining revenue needed as R and calculate it:
[tex]\[ R = 500 - 300 = \$200 \][/tex]
The revenue from selling y lemon bars is $1.50y, so we have:
[tex]\[ 1.50y \geq 200 \][/tex]
[tex]\[ y \geq \frac{200}{1.50} \][/tex]
[tex]\[ y \geq 133.33 \][/tex]
Since we cannot sell a fraction of a lemon bar, we round up to the nearest whole number, so at least 134 lemon bars must be sold.
Now let's check the expenses for the lemon bars. We have $100 - $37.50 = $62.50 left for expenses. The cost to prepare each lemon bar is $0.20, so we calculate the maximum number of lemon bars (y) that can be prepared with the remaining expenses:
[tex]\[ 0.20y \leq 62.50 \][/tex]
[tex]\[ y \leq \frac{62.50}{0.20} \][/tex]
[tex]\[ y \leq 312.5 \][/tex]
Combining the two conditions for y, we find that y must be at least 134 but no more than 312.
Therefore, one possible ordered pair that satisfies all conditions is (x, y) = (150, 134). This means that at least 150 cups of lemonade and at least 134 lemon bars were sold last Monday to meet the revenue and expense conditions.

The missing number using Euler's formula is: Option A. 17
The maximum volume of a square pyramid is: Option B. 4,608
What is Euler's formula?"It is a geometrical formula. V − E + F = 2, where V represents number of vertices, E represents number of edges and F represents number of faces."
What is square pyramid?"Square pyramid is a three dimensional geometrical figure where four triangular sides are associated to square base."
What is cube?"A cube is a three-dimensional geometric structure with six congruent square face."
Formula for volume of a square pyramid:[tex]V=\frac{1}{3}a^{2}h[/tex]
where [tex]a[/tex] represents the length of square base and [tex]h[/tex] represents the height of the pyramid.
Consider the first question,
number of vertices (V) = 13
number of edges (E) = 28
So, using Euler's formula:
[tex]13-28+F=2[/tex]
⇒ [tex]-15+F=2[/tex]
⇒ [tex]F=2+15[/tex]
⇒ [tex]F=17[/tex]
So, the number of faces are 17.
Hence, the correct answer is option A. 17
Consider last question,
the side length of a cube = 24 cm
As the square pyramid fit inside a cube.
⇒ the length of the square base of a pyramid [tex]b[/tex] = 24 cm
and the height of a square pyramid [tex]h[/tex] = 24 cm
So, the volume of a square pyramid is,
[tex]V=\frac{1}{3} a^{2} h[/tex]
⇒ [tex]V=\frac{1}{3}[/tex] × [tex]24^{2}[/tex] × [tex]24[/tex]
⇒ [tex]V= 4608[/tex] [tex]cm^{3}[/tex]
Therefore, the maximum volume of a square pyramid that can fit inside a cube with a side length of 24 cm is [tex]4608[/tex] [tex]cm^{3}[/tex].
And the correct answer is option B. 4,608

D) The number of observations is 15.
Please give the correct answer, there will be consequences if you don't which include being reported
Answer:
The correct option is D.
Step-by-step explanation:
From the given figure it is clear that two dots above 2, three dots above 3 five dots above 4, three dots above 5, and two dots above 6. It means the data set is
2, 2, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 6, 6
Total number of observations = 15
Therefore option D is correct.
15 is an odd number, so the median of the data is

Circle O is shown below. The diagram is not drawn to scale.
If m∡R = 28°, what is m∡ O?
Please Explain.
Answer:
Measure of angle O is 56 degrees.
Step-by-step explanation:
We can see from diagram that NQ is minor arc and NRQ is major arc. Our angle R (inscribed angle) and O (central angle) are corresponding to minor arc NQ. We will use inscribed angle theorem which states that measure of inscribed angle is one-half the measure of central angle.
We are given that measure of inscribed angle R is 28 degrees. To find measure of our central angle O we will multiply 28 by 2.
[tex]28*2=56[/tex]
Therefore, measure of angle O will be 56 degrees.

Two cars leave towns 360 kilometers apart at the same time and travel toward each other. One car's rate is 12 kilometers per hour less than the other's. If they meet in 2 hours, what is the rate of the slower car?
The speed of the slower car is 84 km/h. This was calculated by using the distance equals rate times time formula, setting up an equation based on the combined distance both cars travel and the time they take to meet, and solving for the unknown rate.
Explanation:Two cars leave towns 360 kilometers apart and travel toward each other; one car travels at a rate 12 kilometers per hour slower than the other. They meet in 2 hours, so we need to find the rate of the slower car. To solve this, we'll use the formula for distance which is rate × time. Let's denote the rate of the faster car as r and the rate of the slower car as r - 12. Since they meet in 2 hours, the faster car would have traveled 2r kilometers and the slower 2(r - 12) kilometers. The total distance covered by both cars should add up to 360 km, which gives us the equation 2r + 2(r - 12) = 360.
Simplifying the equation gives 4r - 24 = 360, and adding 24 to both sides gives 4r = 384. Dividing both sides by 4, we get r = 96. Therefore, the speed of the slower car, which is 12 km/h less than the faster car, is 96 - 12 = 84 km/h.

6/x+7 - 3/x-2
To simplify the given expressions into one fraction, we find a common denominator for each set of fractions, adjust the numerators accordingly, and then combine the numerators over the common denominator.
To simplify the given expressions into one fraction, we need to find a common denominator and combine the fractions accordingly. Let's go through each expression step by step.
For the expression 7/x-3 + 3/x-5, the common denominator would be (x-3)(x-5). We need to multiply each fraction by the denominator that it's missing to get common denominators, and then sum the numerators over the common denominator.
The expression -5/x-3 - (-4)/(x+2) involves subtracting fractions. To simplify, we again find a common denominator, which is (x-3)(x+2), and proceed similarly to the first expression.
For 6/x+7 - 3/x-2, the common denominator is (x+7)(x-2). We perform the same process of equating denominators and combining.
To illustrate with the first expression:
(7(x-5))/((x-3)(x-5)) + (3(x-3))/((x-3)(x-5)) = (7x - 35 + 3x - 9)/((x-3)(x-5))
Combine the numerators to get a single fraction:
(10x - 44)/((x-3)(x-5))
Apply the same approach to the other two expressions to get them into a single fraction form.

[tex]2x^2+3x-7=x^2+5x+39[/tex]
[tex]2x^2-x^2+3x-7=x^2-x^2+5x+39[/tex]
[tex]x^2+3x-7=5x+39[/tex]
[tex]x^2+3x-5x-7-39=5x-5x+39-39[/tex]
[tex]x^2-2x-46=0[/tex]
Using quadratic formula, we will get:
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
[tex]x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-46)}}{2(1)}[/tex]
[tex]x=\frac{2\pm\sqrt{4+184}}{2}[/tex]
[tex]x=\frac{2\pm\sqrt{188}}{2}[/tex]
[tex]x=\frac{2\pm2\sqrt{47}}{2}[/tex]
