Answer:
[tex]Area = 229.6125in^2[/tex]
Step-by-step explanation:
Given
[tex]h = 14in[/tex] --- height
[tex]d =4.5in[/tex] --- diameter
Required
The minimum amount of paper needed
This implies that we calculate the surface area of the can (cylinder)
This is calculated as:
[tex]Area = 2\pi r(r + h)[/tex]
Where
[tex]r = \frac{1}{2}d[/tex]
So, we have:
[tex]r = \frac{1}{2} *4.5[/tex]
[tex]r = 2.25[/tex]
This gives:
[tex]Area = 2 * 3.14 * 2.25(2.25 + 14)[/tex]
[tex]Area = 2 * 3.14 * 2.25*16.25[/tex]
[tex]Area = 229.6125in^2[/tex]

The ratio of boys to girls in a class
is 5:7. There are 36 students in the
class. How many more girls than boys
are there?
Answer:
tbh i may be too late but the answer is 6
Step-by-step explanation:
the ratio 5:7 in the question is basically saying for every 5 boys are 7 girls
if you multiply the number of boys by 5 ( which would equal 15) you would have 21 girls, 15 + 21 equals 36. 21- 15= 6 giving us the anser

[tex] (x-1.3) ^2 + (y+3.5) ^2= 37 [/tex]
Step-by-step explanation:
Radius of the circle [tex] r = \sqrt {37}\: units [/tex]
Center of the circle (h, k) = (1.3, - 3.5)
Equation of the circle in center radius form is given as:
[tex] (x-h) ^2 + (y-k) ^2= r^2 [/tex]
Plugging the values of h, k and r in the above equation, we find:

Answer:
The line equation is Y=(1/2)x+2
Step-by-step explanation: Start with the standard from: y=mx+b
Find the slope, or change in the y value divided by change in the x value.
For this graph the slope is 1/2 meaning the y value goes up once every time the x value goes up two. this is represented by the m value
Now we need to find the y intercept, or where the graph passes through the y intercept, this is represented by b
We find the intercept by inserting a point n the line into our equation and solving for b:
Point: (2,3) Equation: y=(1/2)x+b
3=(1/2)2+b
3=1+b

The weights of eight puppies have the following statistics:
mean: 10
median: 7.5
mode: 7
List one set of possible weights in the table below.
Answer:
7, 7, 7, 7.5, 7.5, 14, 20, 10
Step-by-step explanation:
Since the median has to be 7.5, you know that the 4th and 5th numbers have to average out to 7.5. In simpler terms, the two numbers have to add up to 15 so that when you divide them by 2, you get 7.5. Then you know that the mode is 7. So, the magority of the numbers have to be 7. This is why I made the first 3 numbers 7. Then you know that the mean is 10, so all the numbers have to add up to 80. So, if you add up the numbers you have so far you get 36. This means that the remaning numbers have to add up to 44. Here you can really choose any numbers you want, as long as they add up to 44. That is why I chose, 14, 20, and 10. Lastly to check the numbers you put in, find the mean, median and mode. If they all match up with median: 7.5, mean: 10, and mode: 7, then your numbers work! Hope that helps!
✌
One possible data set can be -
8, 7, 8, 7, 8, 7, 15, 7, 13
We have the following statistics for weights of eight puppies -
Mean: 10
Median: 7.5
Mode: 7
We have to list the set of possible weights for eight puppies.
Define Mean, Median and Mode for a given set of data.The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The median is the middle value when a data set is ordered from least to greatest.
The mode is the number that occurs most often in a data set.
According to the question, we have -
Number of puppies = 8
Mean = 10
Median = 7.5
Mode =7
Assume the sum of weights of all puppies be x. Therefore -
[tex]$\frac{x}{8} = 10[/tex]
x = 80
Now -
Mode = 7 → This means that the number 7 has occurred the most in the set.
Median = 7.5 → This means that 7 is the middle value when a data set is ordered from least to greatest. The data set can be -
8, 7, 8, 7, 8, 7, 15, 7, 13
Hence, one possible data set can be -
8, 7, 8, 7, 8, 7, 15, 7, 13

Rewrite the function by completing the square. f(x)=x^{2}+8x+4
Answer:
[tex]\implies f(x) = ( x + 2)^2[/tex]
Step-by-step explanation:
Given :-
f(x) = x² + 8x + 4 .And we need to rewrite the function by completing the square. The function is ,
[tex]\implies f(x) = x^2+8x + 4[/tex]
We can rewrite the function in the form of ,[tex]\implies ( a + b)^2= a^2+b^2+2ab [/tex]
Rewriting the function :-
[tex]\implies f(x) = x^2+8x + 4\\\\\implies f(x) = x^2 + 2.2.2x + 2^2[/tex]
This is similar to the whole square form stated above . So ,[tex]\implies f(x) = ( x + 2)^2[/tex]
Hence the function in whole square form is (x + 2)² .

You deposit $300 in a savings account. The account earns. 1% simple interest per year. What is the interest earned after 3 years? The balance after 3 years?
Please help, urgent
Answer:
9.09, 309.09
Step-by-step explanation:
Year1 300x.01=3. Balance is 303/(300+3)
Year2 303x.01=3.03 balance is 306.03
Year3 306.03x.01=3.06 balance=309.09
Answer:
Interest earned = $9
Balance after 3 years = $309
Step-by-step explanation:
For simple interest, the formula is I = PRT, where I is the interest earned or paid, P is the principal amount borrowed/deposited, R is the rate as a decimal, and T is the time in years.
I = PRT
I = (300)(0.01)(3)
I = 9
Add that to the amount deposited to start, and you have the balance aftere 3 years. $300 + 9 = $309

The time it takes to fly from Los Angeles to New York varies inversely as the speed of the plane. If
the trip takes 6 hours at 900 km/h, what would be the speed if the trip took 10 hours?
Answer: speed is 540 km/h
Step-by-step explanation: Lets mark speed as v.
Because distenace is same, you can mark 6 h · 900 km/h = 10 h · v
and v = 5400 km / 10 h = 540 km/h.
Or using inverse proportions : 10 h / 6 h = v / 900 km/h .
Before multiplying you turn lastproportion around :
10 h / 6 h = 600 km/ h / v ,which gives 10 v = 6 · 900 km/h
and result is same

Jamie is working on simplifying a problem with negative exponets and got the answer 1/4³. What might Jamie's original expression have been? In other words, work backwards and rewrite this expression with a negative exponet
Answer:
Your answer would be 4^-3.
Step-by-step explanation:
So, a negative exponent by definition, is writing out 1/x^y. Where x is the number and y is the negative exponent.
In this case, 4 would be the number and -3 would be the negative exponent.
So we're going from 1/x^y to x^-y in order to solve this. Therefore, this is something where the numbers can just be plugged in.
1/x^y ---> x^-y
1/4^3 ---> 4^-3
Your answer would be 4^-3.

The management of a relatively new social networking website named BooglePlus is conducting a pilot study comparing use of its own site with use of a longer established social networking site named FaceList. Some articles published on the Internet give the reader the opportunity to register votes (called "likes") for the article on social networking sites to which the reader belongs. A BooglePlus employee selects from the Internet a random sample of 28 articles where the opportunity is given for registering votes for the article on both BooglePlus and Face List. Letting x be the number of votes on FaceList and y be the number of votes on the BooglePlus, the slope of the least squares regression line of y on x is found to be 0.0623, with a standard error of 0.0224.

What could be used to compute a 95% confidence interval for the slope of the population regression line of y on x?
Answer:
0.0623 ± ( 2.056 )( 0.0224 ) can be used to compute a 95% confidence interval for the slope of the population regression line of y on x
Step-by-step explanation:
Given the data in the question;
sample size n = 28
slope of the least squares regression line of y on x or sample estimate = 0.0623
standard error = 0.0224
95% confidence interval
level of significance ∝ = 1 - 95% = 1 - 0.95 = 0.05
degree of freedom df = n - 2 = 28 - 2 = 26
∴ the equation will be;
⇒ sample estimate ± ( t-test) ( standard error )
⇒ sample estimate ± ( [tex]t_{\alpha /2, df[/tex]) ( standard error )
⇒ sample estimate ± ( [tex]t_{0.05 /2, 26[/tex]) ( standard error )
⇒ sample estimate ± ( [tex]t_{0.025, 26[/tex]) ( standard error )
{ from t table; ( [tex]t_{0.025, 26[/tex]) = 2.055529 = 2.056
so we substitute
⇒ 0.0623 ± ( 2.056 )( 0.0224 )
Therefore, 0.0623 ± ( 2.056 )( 0.0224 ) can be used to compute a 95% confidence interval for the slope of the population regression line of y on x

Answer:
1. 156 2. 84 3. 74
Step-by-step explanation:
1. b x h. 8 x 8 is every side on the square so one side is 64 and the one behind it is 64 also which is 128 and since that is the case with the other sides its 128 + 128 = 156
2. 1/2 x b x h = 1/2 x 4 x 3 = 6 x 2 because of the side behind it that is the same = 12. 6 x 5 = 30; 6 x 4 = 24; 6 x 3 = 18. 12 + 30 + 24 + 18 = 84
3. b x h. 2.5 x 2 = 5 x 2 because of the other side = 10; 7 x 2.5 = 17.5 x 2 = 35; 7 x 2 = 14 x 2 = 28. 10 + 35 + 28 = 76
