Answer:

there were 223 child plates and 149 adult plates

Step-by-step explanation:

There were 223 child plates.

Since there were a total of 372 plates, there will be 149 adult plates (223 + 149 = 372)

To verify, the total amount raised would be $2121.50:

3.50c + 9a = 2121.50

3.50*223 + 9*149 = 780.50 + 1341.00= $2121.50

Answer:

B is the better buy.

Step-by-step explanation:

A: conical container: volume = π(6/2)²*9/3 = 27π

B: cylindrical container: volume = π(6/2)²*9 = 81π

Cost per unit volume:

A: $1.75/(27π) = $0.0206

B: $3.75/(81π) = $0.0147

So B is cheaper.

B is the better buy.

Answer:

$2.25

Step-by-step explanation:

First, you have to add the amount that Aaron paid. Then, subtract it from 10, which is the amount of the bill he is paying with.

5.25 + 2.50 = 7.75

10-7.75 = 2.25

Answer:

$2.25

Step-by-step explanation:

First, we will find out how much he needs to pay.

$5.25 + $2.50 = $7.75

Then, we will find the amount of change he should receive.

$10.00 - $7.75 = $2.25

Answer:

i wrote an explanation and the answers below!

Step-by-step explanation:

so ill give you a few tips on these!

1/2 can be written as 0.50 since its half .

1/4 can be written as 0.25 since its fourth (i dont know how to say it loll) ?

2 1/2 is 2.50 because it has 2 and 0.5

now ill just solve the rest since i explained

3 1/4 = 3.25

20 1/2 = 20.5

10.

to solve for these you have to simplify and look for the GCF (greatest common factor)

20/4

the GCF is 4 because you can divide 4 to the numerator and the denominator, and because it is the biggest value that you can divide between them

so now you just have to simplify it

20/4 = 5

30/5 = 6

40 / 8 = 5

Answer:

70

Step-by-step explanation:

if 21 is 30%, divide 21 by 3 for get 7, which is 10%. Now multiply 7 by 10 to get 70 which is 100%

Hey! 70 skittles is your answer. My work's below!

- - - - - - - - - - - - - - - - - - - -  

First, use this formula:

a certain percent (%) = a certain number (#)  

# x 100 / %

In this scenario...

30% = 21 (your provided numbers)

21 x 100 / 30 (the formula in action)

2,100 / 30 = 70

(2,100 is the result of 21 x 100, so divided by 30 you have 70!)

Using the z-distribution, as we are working with a proportion, it is found that there is evidence that the phrasing may have influenced responses.

At the null hypothesis, it is tested if there is no difference between the proportions, that is:

[tex]H_0: p_1 - p_2 = 0[/tex]

At the alternative hypothesis, it is tested if there is difference, that is:

[tex]H_1: p_1 - p_2 \neq 0[/tex]

For each sample, we have that:

[tex]p_1 = \frac{463}{615} = 0.7528, s_1 = \sqrt{\frac{0.7528(0.2472)}{615}} = 0.0174[/tex]

[tex]p_2 = \frac{403}{585} = 0.6889, s_2 = \sqrt{\frac{0.6889(0.3111)}{585}} = 0.0191[/tex]

For the distribution of differences, we have that:

[tex]\overline{p} = p_1 - p_2 = 0.7528 - 0.6889 = 0.0639[/tex]

[tex]s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0174^2 + 0.0191^2} = 0.0258[/tex]

It is given by:

[tex]z = \frac{\overline{p} - \mu}{s}[/tex]

In which [tex]\mu = 0[/tex] is the value tested at the null hypothesis.

Hence:

[tex]z = \frac{\overline{p} - \mu}{s}[/tex]

[tex]z = \frac{0.0639 - 0}{0.0258}[/tex]

[tex]z = 2.47[/tex]

Considering a two-tailed test, as we are testing if the proportion is different of a value, and a significance level of 0.05, the critical value is [tex]|z^{\ast}| = 1.96[/tex].

Since the absolute value of the test statistic is greater than the critical value, it is found that there is evidence that the phrasing may have influenced responses.

Answer:

80

Step-by-step explanation:

The 4 doesn't matter right now unless you were solving for area. Visualize the shape as a normal rectangle with no cut out. That would make the bottom line 10+10+10 which equals 30. The top line is the same as the bottom, so that would also be 30. Then you just have the two sides which are both 10, combined them and they would add up to 20. Perimeter is the distance around the edge of a shape. You find the perimeter by adding up the distance of all the sides. So in conclusion, you're answer will be 30+30+10+10 which equals 80.

Answer:

28

Step-by-step explanation:

Given:

Let [tex]x[/tex] = first number

[tex]\implies \dfrac76x = \textsf{second number}[/tex]

Therefore, as the sum of the two numbers is 52:

[tex]\implies \dfrac76x+x=52[/tex]

[tex]\implies \dfrac76x+\dfrac66x=52[/tex]

[tex]\implies \dfrac{13}{6}x=52[/tex]

[tex]\implies13x=52 \cdot 6[/tex]

[tex]\implies13x=312[/tex]

[tex]\implies x=\dfrac{312}{13}[/tex]

[tex]\implies x=24[/tex]

Therefore, the largest number is:

[tex]\implies \dfrac76\cdot 24 =\dfrac{168}{6}=28[/tex]

Answer:

area of a deck

A= External area - Internal area

A = length x width

A = ( 44ft x 28ft) - ( 32ft x 16ft)

A = 720ft²

Substitute [tex]y = x^{\frac{2n-1}2}[/tex] and [tex]dy = \frac{2n-1}2 x^{\frac{2n-3}2} \, dx[/tex]. Then the integral is

[tex]\displaystyle \int_0^\infty \frac{x^{\frac{2n-3}2} \tan^{-1}\left(x^{2n-1}\right)}{1 + x^{2n-1}} \, dx = \frac2{2n-1} \underbrace{\int_0^\infty \frac{\tan^{-1}\left(y^2\right)}{1 + y^2} \, dy}_I[/tex]

which is to say, the integral is now independent of n. Then

[tex]\displaystyle \sum_{n=1}^\infty (-1)^{n+1} \int_0^\infty \frac{x^{\frac{2n-3}2} \tan^{-1}\left(x^{2n-1}\right)}{1+x^{2n-1}} \, dx = I \sum_{n=1}^\infty \frac{2(-1)^{n+1}}{2n-1}[/tex]

Let's evaluate the sum. Recall that if |x| < 1, we have

[tex]\displaystyle \frac1{1-x} = \sum_{n=0}^\infty x^n[/tex]

which means

[tex]\displaystyle \frac1{1+x^2} = \frac1{1-(-x^2)} = \sum_{n=0}^\infty \left(-x^2\right)^n = \sum_{n=0}^\infty (-1)^n x^{2n}[/tex]

By the fundamental theorem of calculus, integrating both sides gives

[tex]\displaystyle \tan^{-1}(x) = \sum_{n=0}^\infty (-1)^n \frac{x^{2n+1}}{2n+1} = \sum_{n=1}^\infty (-1)^{n+1} \frac{x^{2n-1}}{2n-1}[/tex]

As x approaches 1 from below, we have

[tex]\displaystyle \lim_{x\to1^-} \tan^{-1}(x) = \lim_{x\to1^-} \sum_{n=1}^\infty (-1)^{n+1} \frac{x^{2n-1}}{2n-1}[/tex]

[tex]\displaystyle \frac\pi4 = \sum_{n=1}^\infty \frac{(-1)^{n+1}}{2n-1} \left(\lim\limits_{x\to1^-} x^{2n-1}\right) = \sum_{n=1}^\infty \frac{(-1)^{n+1}}{2n-1}[/tex]

and so

[tex]\displaystyle \sum_{n=1}^\infty (-1)^{n+1} \int_0^\infty \frac{x^{\frac{2n-3}2} \tan^{-1}\left(x^{2n-1}\right)}{1+x^{2n-1}} \, dx = \frac\pi2 I[/tex]

Now compute the remaining integral. First split it at y = 1 :

[tex]\displaystyle I = \int_0^1 \frac{\tan^{-1}\left(y^2\right)}{1 + y^2} \, dy + \int_1^\infty \frac{\tan^{-1}\left(y^2\right)}{1 + y^2} \, dy[/tex]

In the second integral, notice that replacing [tex]z=\frac1y[/tex] and [tex]dy = -\frac{dz}{z^2}[/tex] yields

[tex]\displaystyle \int_1^\infty \frac{\tan^{-1}\left(y^2\right)}{1 + y^2} \, dy = - \int_1^0 \frac{\tan^{-1}\left(\frac1{z^2}\right)}{1 + \frac1{z^2}} \, \frac{dz}{z^2}  = \int_0^1 \frac{\tan^{-1}\left(\frac1{z^2}\right)}{1+z^2} \, dz[/tex]

The inverse tangent function has the property

[tex]\tan^{-1}(x) = \dfrac\pi2 - \tan^{-1}\left(\dfrac1x\right)[/tex]

so it follows that

[tex]\displaystyle \int_0^1 \frac{\tan^{-1}\left(\frac1{z^2}\right)}{1+z^2} \, dz = \frac\pi2 \int_0^1 \frac{dz}{1+z^2} - \int_0^1 \frac{\tan^{-1}(z^2)}{1+z^2} \, dz[/tex]

and hence

[tex]\displaystyle I = \int_0^1 \frac{\tan^{-1}\left(y^2\right)}{1 + y^2} \, dy + \frac\pi2 \int_0^1 \frac{dz}{1+z^2} - \int_0^1 \frac{\tan^{-1}(z^2)}{1+z^2} \, dz[/tex]

[tex]\displaystyle I = \frac\pi2 \int_0^1 \frac{dz}{1+z^2}[/tex]

[tex]I = \dfrac\pi2 \times \dfrac\pi4 = \dfrac{\pi^2}8[/tex]

Then the original expression has an exact value of

[tex]\displaystyle \sum_{n=1}^\infty (-1)^{n+1} \int_0^\infty \frac{x^{\frac{2n-3}2} \tan^{-1}\left(x^{2n-1}\right)}{1+x^{2n-1}} \, dx = \frac\pi2 \times \frac{\pi^2}8 = \boxed{\frac{\pi^3}{16}}[/tex]
