15 x 4 = 60, which means that Beetle has 15 bottles of water and that Ameezy has bottles. 45 - 15 = 30.
Hope this helps :)
Answer:
36 bottles.
Step-by-step explanation:
If you wrote them out, like 1 over 4, 2 over 8, and added up their totals at the bottom, you would eventually reach 60. The last column has 12 over 48, so we subtract 12 from 48, which gives us 36. So the answer is 36 bottles.

At an international conference, flags from 12 different countries will be displayed. Of these flags, 6 are from the continent of South America and 6 flags are from the continent of Europe. The flags will be displayed in a row, alternating between continents. A flag from South America will be in the first position. In how many ways can the flags be displayed?
Using the Fundamental Counting Theorem, it is found that the flags can be displayed in 518,400 ways.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem, we have that odd positions get South American countries, hence:
[tex]n_1 = 6, n_3 = 5, n_4 = 3, \cdots, n_11 = 1[/tex]
Even positions get European countries, hence:
[tex]n_2 = 6, n_4 = 5, \cdots, n_12 = 1[/tex]
Hence, since the number of ways for both the South American and European countries is the factorial of 6, we have that:
N = 6! x 6! = 518,400
The flags can be displayed in 518,400 ways.

In a certain town there were 171 robberies last year. This year the number of robberies has gone down 39%. How many robberies were there this year, to the nearest whole number?
Answer:
104 robberies
Step-by-step explanation:
No of robberies last year = 171
Robberies for this year reduced by 39%
Percentage robberies of this year reduced to 39%
39% * 171
= 39/100 * 171
= 66.09
That is to say that this year robberies reduced by 66.09
Therefore this year robberies = 171 - 66.09
= 104.31
= 104 to the nearest

The cost of tuition at a 2 year school is $12,000 per academic year. Alejandro is eligible for $7,500 in financial aid to cover tuition each year. He will save money for one year to cover the remaining cost of tuition for his two years of school. What is the minimum amount he needs to save each month? $375 $450 $750 $1,200.
Division is one of the most basic arithmetical operators. The amount that Alejandro need to save for each month is $375.
What is division?The division is one of the most basic arithmetical operators. When we divide a number (P) by another number(q), then it tells us how many times the other number(q) must be added to itself to form the first number(P).
It is given that the cost of tuition for the two years is $12,000, while the financial aid that Alejandro is eligible for is $7500, therefore, the amount that he will not be able to pay with his scholarship(financial aid) will be the difference in the fees of the student and the financial aid he is getting.
Difference = Two-year tuition fees - Financial Aid
= $12,000 - $7,500
= $4,500
Now, since Alejandro needs to save for a year so the sum he saves is $4500 therefore, the amount he needs to save each month can be written as,
[tex]\text{Amount Alehjandro needs to save each moth}=\dfrac{\text{Amount that Alejandro need to save}}{\text{Number of months he needs to save}}[/tex]
[tex]\text{Amount Alehjandro needs to save each moth}=\dfrac{4500}{12} = \$375[/tex]
Hence, the amount that Alejandro need to save for each of the month so that he can pay his tuition fee is $375.

Find the value of x. Then find the angle measures of the trapezoid.
Sum of angle
measures: 360°
the value of x is 120 ....
3. Find the area of a trapezoid with bases 20 cm and 14 cm and height 5 cm.
Given :
Base = 20 cm and 14 cm.Height = 5 cm.To find :
Area of trapezoid.Solution :
We know,
[tex]{\qquad \dashrightarrow{ \bf{Area_{(Trapezoid)}= \dfrac{1}{2 } \times (b_{1} + b_{2}) \times h} }}[/tex]
Now, Substituting the values :
[tex]{\qquad \dashrightarrow{ \bf{Area_{(Trapezoid)}= \dfrac{1}{2 } \times (20 + 14) \times 5} }}[/tex]
[tex]{\qquad \dashrightarrow{ \bf{Area_{(Trapezoid)}= \dfrac{5}{2 } \times 34} }}[/tex]
[tex]{\qquad \dashrightarrow{ \bf{Area_{(Trapezoid)}= \dfrac{5}{ \cancel2 } \times \cancel{34}} }}[/tex]
[tex]{\qquad \dashrightarrow{ \bf{Area_{(Trapezoid)}=5 \times 17} }}[/tex]
[tex]{\qquad \dashrightarrow{ \bf{Area_{(Trapezoid)}=85} }}[/tex]
Therefore,
The area of the trapezoid is 85 cm² .Answer:
85cm²
Step-by-step explanation:
Here we are given a trapezium with base = 20cm and 14cm and height = 5cm . And we are interested in finding the area of the trapezium .
Figure :-
[tex]\setlength{\unitlength}{1.5cm}\begin{picture}\thicklines\qbezier(0,0)(0,0)(1,2.2)\qbezier(0,0)(0,0)(4,0)\qbezier(3,2.2)(4,0)(4,0)\qbezier(1.5,2.2)(0,2.2)(3,2.2)\put(0.8,2.4){$\bf A $}\put(3,2.4){$\bf D $}\put(-0.3,-0.3){$\bf B$}\put(4,-0.3){$\bf C$}\put(4.4,0){\vector(0,0){2.2}}\put( 4.4, 0){\vector(0,-1){0.1}}\put(4.6,1){$\bf 5\ cm$}\put(0, -0.5){\vector(1,0){4}}\put(0, -0.5){\vector( - 1, 0){0.1}}\put(1.7, - 0.9){$\bf 20\ cm $}\put(0.8, 2.8){\vector(1,0){2.5}}\put(0.8, 2.8){\vector( - 1, 0){0.1}}\put(1.7, 3){$\bf 14\ cm $}\end{picture} [/tex]
As we know that the area of trapezium is given by ,
[tex]\longrightarrow\rm Area =\dfrac{1}{2}(sum \ of \ || \ sides)\times height [/tex]
Here 20cm and 14cm are parallel sides .Substitute the respective values in stated formula,
[tex]\longrightarrow\rm Area =\dfrac{1}{2}(20cm +14cm)5cm \\[/tex]
Solve the parenthesis ,
[tex]\longrightarrow\rm Area =\dfrac{1}{2}\times (34cm)(5cm)[/tex]

Stefan said that the y-intercept for the graph of the function f(x)=3log(x−7)+1 is 1. He also said that as x approaches positive infinity, the graph of f(x) approaches positive infinity. Describe which of Stefan's statements, if any, are incorrect, and, if so, correct the statements.
Answer:
see below
Step-by-step explanation:
f(x)=3log(x−7)+1
There is no y intercept
log (x) does not intercept the y axis. This shifts the function 7 units to the right so the graph will not intercept the y axis
Answers:
His first statement is incorrect
His second statement is correct.
======================================
Explanation:
The first statement is incorrect because plugging x = 0 into f(x) leads to
f(x) = 3*log(x-7)+1
f(0) = 3*log(0-7)+1
f(0) = 3*log(-7)+1
We stop here because we cannot take the log of a negative number (unless you want a complex number but that's for another time). This means that x = 0 is not in the domain. The domain is x > 7 to ensure that x-7 > 0. That way we avoid taking the log of a negative number, and taking the log of zero as well.
The vertical asymptote is at x = 7 and the log curve is entirely to the right of it, so there's no way it's reaching the y axis.
Simply put: there is no y intercept for this function.
---------------------
The second statement is correct.
The function y = log(x) has y go off to infinity when x does.
The same applies to y = 3log(x) and y = 3log(x-7) and y = 3log(x-7)+1
We can say it "rises to the right" as another way of describing part of the end behavior.
A graph can confirm this as shown below.
A Buffalo school district randomly tests its employees to determine how many have gotten the flu shot this season. Their sample shows that 15 of them have gotten it, and 27 have not. Estimate the true proportion of employees in the district who have gotten a flu shot, with a 90% confidence level. Check conditions to see if you can use normal sampling distribution for sample proportion
Using the z-distribution, as we are working with a proportion, the 90% confidence level estimate for the true proportion of employees in the district who have gotten a flu shot is (0.2355, 0.4784).
What is a confidence interval of proportions?As long as there are 10 successes and 10 failures in the sample, that is, [tex]n\pi \geq 10[/tex] and [tex]n(1 - \pi) \geq 10[/tex], a confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem, the parameters are:
[tex]n = 42, \pi = \frac{15}{42} = 0.3571, z = 1.645[/tex]
We have the [tex]n\pi = 15, n(1 - \pi) = 27[/tex], hence you can find the interval.
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3571 - 1.645\sqrt{\frac{0.3571(0.6429)}{42}} = 0.2355[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3571 + 1.645\sqrt{\frac{0.3571(0.6429)}{42}} = 0.4787[/tex]
The 90% confidence level estimate for the true proportion of employees in the district who have gotten a flu shot is (0.2355, 0.4784).

Answer:
34/9 or 3 7/9
Step-by-step explanation:
to do this u must turn 5 2/3 into an improper fraction first
5 2/3 is also 17/3
to divide you can multiply the first number by the second numbers reciprocal or flipped numbers
17/3 * 2/3
you flipped 3/2 to make it 2/3
for 17/3 * 2/3 just multiply across
34/9
then you can make that a mixed number
3 7/9
that is your answer
Answer:
the answer is 3 7/9
Step-by-step explanation:
in order to find the answer to this you need to change the mixed fraction into a improper fraction then do the reciprocal on 3/2 would would change to 2/3. Then, since you cant divide fractions you need to multiply 17/3×2/3 which would give you 34/9. But since 34/9 is improper, you need to change it to a mixed fraction and simplify if you can. So that means your final answer should be 3 7/9
