The results of a poll show that the percent of people who want a new restaurant is in the interval (24%, 38%) . There are 112,483 people in the city.
What is the interval for the number of people who are likely to want this restaurant in their city?
Round to the nearest person.
Answer: (26996, 42744)
Step-by-step explanation:
24% of 112,483 = 26,995.92 --> rounded to the nearest person is 26,996
38% of 112,483 = 42,743.54 --> rounded to the nearest person is 42,744
The number of people who want a new restaurant is somewhere between 26,996 and 42,744.
Answer:
26,996-42,744
Step-by-step explanation:
To calculate the spam of the people that who are likely to want this restaurant you just have to multiply the total number people in the city by the two points in the extremes of the intervals.
24% * 112,483=26996
and the other one would be:
38%* 112,483= 42744
And those are the extremes of the interval of people in the city who are likely to want this new restaurant.

Answer:
10.92 m
Step-by-step explanation:
To solve for the height, we first find the area of the triangle. Since the area of a triangle is 1/2 of the base times the height, we get the area to be 109.2. Dividing it by 20 and then multiplying by 2, we get 10.92 as the height.
Lin's goal is to drink 8 cups of water every day.She drank 37 ounces before lunch today.How much more water does Lin need to drink today to reach her goals
Answer:
Lin needs to drink 27 ounces of water to reach her goal.
Step-by-step explanation:
1 cup = 8 fluid ounces.
8 cups = [tex]8\times8=64[/tex] ounces.
As of now Lin has drank 37 ounces of water. So, this means till now she has drank [tex]\frac{37}{8}= 4.625[/tex] cups of water.
In terms of ounces, she needs to drink 64-37=27 ounces of water to reach her goal.
Hence, the answer is 27 ounces or 8-4.625=3.375 cups.
The correct answer is A. 27 ounces. Lin needs to drink 27 more ounces of water to reach her goal of 8 cups (64 ounces) of water daily.
To determine how much more water Lin needs to drink to reach her goal, we need to follow these steps:
First, we convert Lin's goal of drinking 8 cups of water into ounces. Since 1 cup = 8 ounces, 8 cups = 8 * 8 = 64 ounces.Next, we subtract the amount of water Lin has already drank from her goal. Lin has already consumed 37 ounces.Now, we calculate the remaining amount of water she needs: 64 ounces (goal) - 37 ounces (already drank) = 27 ounces.Thus, Lin needs to drink 27 ounces more water today to reach her goal.
Complete question:
Lin's goal is to drink 8 cups of water every day.She drank 37 ounces before lunch today.How much more water does Lin need to drink today to reach her goals? (8 fluid ounces = 1 cup)

if rectangle ABCD is dilated by a scale factor of 3 with a center of dilation at vertex D, what is the perimeter of A'B'C'D'?
Final answer:
To find the perimeter of the dilated rectangle A'B'C'D', we need to know the dimensions of the original rectangle ABCD and the scale factor of the dilation. The perimeter of A'B'C'D' is equal to the sum of the lengths of all the sides in the dilated rectangle. Since AB = A'B' and BD = B'D', the perimeter can be simplified to AB + BC + CD + BD.
Explanation:
To find the perimeter of the dilated rectangle A'B'C'D', we need to know the dimensions of the original rectangle ABCD and the scale factor of the dilation.
If the scale factor is 3, it means that each side of the original rectangle will be multiplied by 3 to get the corresponding side of the dilated rectangle.
Since the rectangle ABCD is dilated with a center of dilation at vertex D, the length of side AB remains the same in the dilated rectangle A'B'.
To find the perimeter of A'B'C'D', we need to compute the lengths of all the sides in the dilated rectangle and sum them up.
Perimeter of A'B'C'D' = A'B' + B'C' + C'D' + D'A'
Since AB = A'B' and BD = B'D', the perimeter can be simplified to:
Perimeter of A'B'C'D' = AB + BC + CD + BD
The perimeter of rectangle A'B'C'D', which is a dilation of rectangle ABCD by a scale factor of 3 with center D, is three times larger than the original perimeter of ABCD.
Explanation:If rectangle ABCD is dilated by a scale factor of 3 with a center of dilation at vertex D, to find the perimeter of A'B'C'D', we must first understand that a dilation scales all dimensions by the given factor. If the original lengths of the sides of rectangle ABCD are 'a' and 'b', with CD and AD being adjacent to vertex D, then after the dilation, the lengths of the corresponding sides would be '3a' and '3b'.
Since the perimeter of a rectangle is calculated by adding together the lengths of all its sides, the formula for the perimeter 'P' before dilation is P = 2a + 2b. After dilation, the new perimeter 'P' of A'B'C'D' will be P = 2(3a) + 2(3b) = 6a + 6b, which is simply three times the original perimeter. Therefore, the perimeter of rectangle A'B'C'D' after dilation is three times larger than the perimeter of the original rectangle ABCD.
A company manufactures televisions in batches of 25 and there is a 1% rate of defects. Find the standard deviation for the number of defects per batch.
Final answer:
To find the standard deviation for the number of defects per batch, use the formula for the standard deviation of a binomial distribution.
Explanation:
To find the standard deviation for the number of defects per batch, we need to use the formula for the standard deviation of a binomial distribution.
Given that the company manufactures televisions in batches of 25 and there is a 1% rate of defects, we can calculate the mean and variance of the number of defects per batch.
The mean (μ) of a binomial distribution is given by μ = np, where n is the number of trials (batch size) and p is the probability of success (defect rate). In this case, μ = 25 * 0.01 = 0.25. The variance (σ^2) of a binomial distribution is given by σ² = np(1-p). In this case, σ² = 25 * 0.01 * (1-0.01) = 0.2475.
The standard deviation (σ) is the square root of the variance, so σ ≈ √0.2475 ≈ 0.4975. Therefore, the standard deviation for the number of defects per batch is approximately 0.4975.
To calculate the standard deviation for the number of defects per batch with a 1% defect rate, use the formula for the standard deviation of a binomial distribution. The standard deviation is approximately 0.4975, indicating the variation in defects per batch.
Explanation:The question you asked is about finding the standard deviation for the number of defects per batch in a manufacturing process where there is a 1% rate of defects.
To calculate the standard deviation for a binomial distribution, which is the case here since each television can be either defective or not, we use the formula: σ = √(np(1-p)), where σ is the standard deviation, n is the number of trials (or televisions), and p is the probability of success (or defect in this context).
Since each batch contains 25 televisions and the defect rate is 1% (0.01), we have:
n = 25
p = 0.01
1-p = 0.99
Plugging these values into the formula we get:
σ = √(25 * 0.01 * 0.99) = √(0.2475) ≈ 0.4975
Therefore, the standard deviation for the number of defects per batch is approximately 0.4975, which means – on average – you would expect the number of defects to vary around this value.
Eve knits scarves for her online store. This week she has already knitted 9 scarves. There are 2 days left in the work week. She set a goal for herself to knit at least 15 scarves and at the most 21 scarves this week. Eve wants to know how many scarves she should knit each day to meet her goal.
Eve should knit between 3 and 6 scarves per day in the next 2 days to meet her goal, with a minimum total of 15 and a maximum of 21 scarves for the week.
Explanation:Eve has already knitted 9 scarves and wants to knit at least 15 scarves and at most 21 scarves by the end of the week. With 2 days left in her work week, we need to calculate how many more scarves she should knit each day to achieve her goal.
First, let's calculate the minimum number of scarves she needs to knit to meet her goal of 15 scarves. She needs to knit 15 - 9 = 6 more scarves. Dividing 6 scarves by 2 days, we find she needs to knit a minimum of 3 scarves per day.
Now, let's calculate the maximum number of scarves to meet her goal of 21 scarves. She needs to knit 21 - 9 = 12 more scarves. Dividing 12 scarves by 2 days, we find she needs to knit a maximum of 6 scarves per day.
Therefore, to meet her goal for the week, Eve should knit between 3 and 6 scarves per day for the remaining two days.
Eve should knit between 3 and 6 scarves per day in the next two days to meet her goal.
To determine the number of scarves Eve should knit each day, we need to find how many more scarves she needs to meet her goal and then spread that number evenly over the 2 remaining days. Eve has made 9 scarves already.
The maximum and minimum scarves can be calculated as below:
Minimum scarves needed [tex]= 15 - 9 = 6[/tex]
Maximum scarves needed [tex]= 21 - 9 = 12[/tex]
Now the remaining scarves need to be completed in 2 days. So, it find number of remaining scarves to be completed per day we divide the maximum and minimum value by 2 as follows:
Minimum scarves per day [tex]= \frac{6}{2} = 3[/tex]
Maximum scarves per day [tex]= \frac{12}{2} = 6[/tex]
Therefore, Eve should knit between 3 and 6 scarves per day in the next two days to meet her goal.

A. 486 units^2
B. 508 units^2
C. 729units^2
D. 405 units^2
Answer:
Correct option is:
A. 486 units²
Step-by-step explanation:
We have to find the surface area of cube with side length 9 units
We know that surface area of cube is:
6s²
where s is the side of the cube
Here, s=9 units
Surface area=6×9×9
= 486 units²
Hence, Correct option is:
A. 486 units²
486 units²
Further explanationGiven:
s = 9 units
Let us find out the surface area of a cube.
The formula of the surface area of a cube is [tex]\boxed{ \ S = 6(s^2) \ }[/tex],
where s is the length of one of the sides.
[tex]\boxed{ \ S = 6(9^2) \ }[/tex]
[tex]\boxed{ \ S = 6(81) \ }[/tex]
[tex]\boxed{ \ S = 6 \times 81 \ }[/tex]
Thus, the surface area of the cube is 486 sq. units.
Notes:
From the formula for surface area, we make it s as a subject.
[tex]\boxed{ \ 6(s^2) = S \ }[/tex]
[tex]\boxed{ \ s^2 = \frac{S}{6} \ }[/tex]
[tex]\boxed{\boxed{ \ s = \sqrt{\frac{S}{6}} \ }}[/tex] ... Equation-1
The formula of the volume of a cube is [tex]\boxed{ \ V = s^3 \ }.[/tex]
Substitute Equation-1 into the volume formula.
[tex]\boxed{ \ V = \bigg( \sqrt{\frac{S}{6}} \bigg)^3 \ }.[/tex]

Answer:
[tex]V = 2622\ in ^ 3[/tex]
Step-by-step explanation:
We have a composite figure, therefore the volume of the figure will be the sum of the volume of both figures.
The volume of the rectangular prism is the product of its length by its width by its height
[tex]V_r = 7 * 12 * 19\\\\V_r = 1596\ in^3[/tex]
The volume of the triangular prism is
[tex]V_t = A_b * l[/tex]
Where [tex]A_b[/tex] is the area of the triangular base and l is the length
[tex]A_b = 0.5 * 9 * 12 = 54\ in^2[/tex]
[tex]V_t = 0.54 * 19 = 1026\ in^3[/tex]
Finally
[tex]V = 1596 + 1026[/tex]
[tex]V = 2622\ in ^ 3[/tex]
The answer is:
The total volume is equal to: [tex]2622in^{3}[/tex]
Why?To calculate the total volume of the composite figure, we need to calculate the volume of both of the figures that creates the composite figure.
So, calculating we have:
First figure:
The first figure has a triangular base (side for this case) and height, to find its volume, we just need to calculate the area of its base and then, multiply it by its height.
We are given that:
[tex]base_{height}=9in\\base_{base}=12in\\length=19in[/tex]
Calculating the area of the side/base, we have:
[tex]A=\frac{b*h}{2}[/tex]
[tex]A=\frac{12in*9in}{2}=54in^{2}[/tex]
Now, calculating the volume, we have:
[tex]Volume_{1}=Area*Length\\\\Volume_{1}=54in^{2}*19in=1026in^{3}[/tex]
Second figure:
The second figure is a rectangle, we can calculate its volume using the following formula:
[tex]Volume_2=base*height*width\\\\Volume_2=12in*7in*19in=1596in^{3}[/tex]
Hence, we can calculate the total volume by adding the first volumen and the second volume:
[tex]TotalVolume=Volume_1+Volume_2\\\\TotalVolume=1026in^{3} +1596in^{3}=2622in^{3}[/tex]
The total volume is equal to [tex]2622in^{3}[/tex]

If triangle ABC is defined by the coordinates A(-4, -4), B(2, -2), C(0, 4) is dilated by a scale factor of 1 2 , with resulting vertex A' at (-2, -2). What is the center of the dilation?
Answer:
the origin, (0, 0)
Step-by-step explanation:
The coordinates of A' are 1/2 those of A, meaning each has been multiplied by the scale factor 1/2. When the dilated points are all the original points multiplied by the scale factor, the center of dilation is the origin.
_____
For center of dilation Q, the image of a point A after dilation by a factor of k is ...
A' = kA + (k-1)Q
Then for points A, A', and dilation factor k, the center of dilation can be found to be ...
(A' -kA)/(k-1) = Q
Here, that is ...
Q = ((-2, -2) -(1/2)(-4, -4))/(1/2 -1) = (0, 0)/(-1/2)
Q = (0, 0)

Answer:
C
Step-by-step explanation:
We can multiply each equation by a constant so they'll equal either 15 or -15 since that is the LCM.
Since the answer choices want us to make the top a negative 15, we'll do that.
[tex]2x-5y=-21 \\ \\ 3(2x-5y)=(-21)*3 \\ \\ 6x-15y=-63[/tex]
To make the y's cancel out, the second equation would have to have the y's coefficient equal 15.

B. f(q) = 2s + 3
C. f(s) = 1/2s - 3/2
D. f(q) = 2q + 3
Answer:
D. f(q) = 2q + 3
Step-by-step explanation:
Choices B and C are eliminated right away because there is no "q" in the definition, just "s". If the function is to be a function of "q", then "q" is expected to appear in the definition.
__
The two variables in the given equation are "s" and "q". If "q" is designated as the independent variable, then the dependent variable is "s". The equation must be solved for "s":
6q = 3s - 9
We observe that the coefficient of "s" is 3, and that all numbers are multiples of 3, so we can divide by 3 to simplify this a bit:
2q = s - 3
Since we want an expression for s alone, we can add 3 to get ...
2q +3 = s
Now, we can write ...
s = f(q) = 2q +3

Find the sine, cosine, and tangent of 45 degrees.
A) Sin 45 degrees = negative square root of 2 divided by 2, cos 45 degrees = negative square root of 2 divided by 2, tan 45 degrees = negative square root of 2
B) Sin 45 degrees = square root of 2 divided by 2, cos 45 degrees = square root of 2 divided by 2, tan 45 degrees = square root of 2
C) Sin 45 degrees = square root of 2 divided by 2, cos 45 degrees = square root of 2 divided by 2, tan 45 degrees = 1
D) Sin 45 degrees = square root of 2 divided by 2, cos 45 degrees = square root of 2 divided by 2, tan 45 degrees = −1
Answer:
The correct answer is option C.
Sin 45 degrees = square root of 2 divided by 2, cos 45 degrees = square root of 2 divided by 2, tan 45 degrees = 1
Step-by-step explanation:
The sin cos tan table used to calculate values of the ratios for different angles can be used for the values.
The table is easily available on the internet.
WE can use a a right-angles isosceles triangle to find the exact values for the angle 45.
The equal sides have length 1. So the thirs side using the pythagoras theorem will be √2.
So
Sin 45 = √2/2
Cos 45 = √2/2
and
Tan 45 = 1
So the correct option is C.
The sine, cosine, and tangent of 45 degrees can be found using the values of the adjacent side, opposite side, and hypotenuse of a right triangle. The sine of 45 degrees is (√2) / 2, the cosine is (√2) / 2, and the tangent is 1.
Explanation:The sine, cosine, and tangent of 45 degrees can be found using the values of the adjacent side, opposite side, and hypotenuse of a right triangle. In this case, for a 45-degree angle, the adjacent side and opposite side are equal, so we can use the Pythagorean theorem to find the value of the hypotenuse. Let's denote the length of the adjacent and opposite sides as x.
Sine (sin) 45 degrees: sin 45 degrees = opposite side / hypotenuse = x / √2x = 1 / √2 = (√2) / 2
Cosine (cos) 45 degrees: cos 45 degrees = adjacent side / hypotenuse = x / √2x = 1 / √2 = (√2) / 2
Tangent (tan) 45 degrees: tan 45 degrees = opposite side / adjacent side = x / x = 1

Step-by-step explanation:
We have been given a table containing a list of few places that are either city or in North America.
Total number of places in that list = 7
That means sample space has 7 possible events.
Given that a place from this table is chosen at random. Let event A = The place is a city.
Now we need to find about what is [tex]P(A^c)[/tex].
That means find find the probability that chosen place is not a city.
there are 3 places in the list which are not city.
Hence favorable number of events = 3
Then required probability is given by favorable/total events.
[tex]P(A^c)=\frac{3}{7}[/tex]

The total ribbon:
[tex]= \rm 1\dfrac{1}{4} +2\dfrac{5}{6} +3\dfrac{1}{2} \\\\=\rm \dfrac{5}{4}+\dfrac{17}{6}+\dfrac{7}{2}\\\\=\dfrac{15+34+42}{12}\\=\dfrac{91}{12}\\\\=7\dfrac{7}{12} \ yards[/tex]
Thus, the total ribbon is 7 whole 7/12 yards if the Traci bought 1 1/4 yards of yellow ribbon, 2 5/6 yards of pink ribbon, and 3 1/2 yards of purple ribbon

¯¯¯¯¯¯ J K is a tangent to circle C . If m ∠ K J L = 27 °, What is m ˆ K L ?
To find the angle ∠KL, knowing m∠KJL = 27°, it is essential to apply the properties of tangents and circles.
The angle ∠KJL can be determined using the properties of tangents and circles. Since JK is a tangent to circle C, we know that angle ∠KJL is equal to half of the intercepted arc KL. Therefore, if m∠KJL = 27°, then m∠KL = 2 × 27° = 54°.

V = 1152π in³
Step-by-step explanation:
The formula for the volume of a hemishere is
[tex] \frac{ \frac{4}{3}\pi {r}^{3} }{2} [/tex]
Next we need to substitute the values from the question in.
[tex] \frac{ \frac{4}{3}\pi {12}^{3} }{2} [/tex]
Then finally we need to simplify.
[tex] \frac{2304\pi}{2} = 1152\pi[/tex]
Can someone please check this? Thanks!
Answer:
Your choice is correct.
Step-by-step explanation:
The amplitude (multiplier of sin( )) is half the diameter, so is 17.5. The midline (value added to the sine function) is the difference between the maximum (50) and the amplitude (17.5), so is 50-17.5 = 32.5. All choices have the correct frequency.
The function will look like ...
f(t) = 17.5·sin(2πt/5) +32.5 . . . . . as you have marked

Ebit goes from $30m to $33m; depreciation goes from $10m to $12m; and interest expense goes from $6 m to $8m. what is the percent change in the numerator of the cash coverage ratio? what is the percent change in the denominator of the cash coverage ratio?
i am pretty sure you add up all of them
The percent change in the numerator for the cash coverage ratio, considering the changes in EBIT and depreciation, is 12.5%. Meanwhile, the percent change in the denominator, based on the interest expense, is 33.33%.
Explanation:The cash coverage ratio is a measure of a company's ability to pay off its obligations and is calculated by adding depreciation and EBIT and then dividing by the interest expense. For this question, we are looking at the percent change in the numerator, which is EBIT + depreciation, and the denominator, which is the interest expense. With EBIT going from $30m to $33m, depreciation going from $10m to $12m, and interest expense going from $6m to $8m we can calculate as follows.
The original numerator value was $40m (EBIT of $30m + depreciation of $10m) and the new numerator is $45m (EBIT of $33m + depreciation of $12m). So, the percent change in the numerator of the cash coverage ratio is ((45-40)/40)*100 = 12.5%. The original denominator was $6m and the new denominator is $8m. Thus, the percent change in the denominator of the cash coverage ratio is ((8-6)/6)*100 = 33.33%.

Which choice is equivalent to the expression below when y is greater or less than 0?
ANSWER
A. y√y
EXPLANATION
The given expression is:
[tex] \sqrt{ {y}^{3} } + \sqrt{16 {y}^{3} } - 4y \sqrt{y} [/tex]
We factor the perfect square in the first two terms to obtain;
[tex] \sqrt{ {y}^{2} \times y} + \sqrt{ {(4y)}^{2} \times y } - 4y \sqrt{y} [/tex]
This simplifies to:
[tex]y\sqrt{y } + 4y \sqrt{y } - 4y \sqrt{y} [/tex]
We simplify to get;
[tex]y\sqrt{y } + 0 = y \sqrt{y} [/tex]
The correct choice is A.
