I believe the answer is $12.25 for 13lbs because it is 0.94 cents per pound. $14.29 = 0.95, $24.25 = 0.97, $9.90 = 0.99.

You sell your bicycle to your friend for 65$ your friend gives you x five dollar bills and y ten dollar bills. There are a total
jeka94

Answer:

There are 5 five dollar bills and 4 ten dollar bills.

Step-by-step explanation:

Given:

Selling price of bicycle =\$65.

The friend gave x five dollar bills and y ten dollar bills.

Total number of bills =9.

To find: Number of five dollar bills and ten dollar bills the friend gave.

Solution:

The friend gave x five dollar bills and y ten dollar bills and the friend gave 9bills in all.

So, x+y=9.

\Rightarrow x=9-y   ...(i)

Selling price of bicycle =\$65.

So, 5x+10y=65...(ii)

Putting the value of x from equation (i) in equation (ii).

\Rightarrow 5(9-y)+10y=65

\Rightarrow 45-5y+10y=65

\Rightarrow 45+5y=65

\Rightarrow 5y=65-45

\Rightarrow 5y=20

\Rightarrow y=\frac{20}{5}

\Rightarrow y=4

Now, putting the value of y in equation (i).

\Rightarrow x=9-4

\Rightarrow x=5

Hence, there are 5 five dollar bills and 4 ten dollar bills.

Degger [83]
(5,60)(10,40)
slope = (40 - 60) / (10 - 5) = - 20/5 = -4

y = mx + b
slope(m) = -4
(5,60)...x = 5 and y = 60
now we sub and find b, the y int
60 = -4(5) + b
60 = -20 + b
60 + 20 = b
80 = b

equation is : y = -4x + 80
function form : f(x) = -4x + 80...where x = number of weeks and f(x) = loads of waste removed

Katrina wants to estimate the proportion of adults who read at least 10 books last year. to do​ so, she obtains a simple random
Vaselesa [24]
E=Z*sqrt (p(1-p)/N), where E= error margin, p=proportion, N=sample size

Katrina's margin error at 85% confidence interval: E=1.96*sqrt (p(1-p)/100) = 0.196 sqrt (1(1-p))

Mathew's margin error at 99% confidence interval: E= 2.58*sqrt (p(1-p)/400) = 0.129 sqrt (p(1-p))

Since both obtained same estimate of proportion (that is, value of p), it can be seen that Mathew's estimate will have a small error (That is, 0.129 is smaller than 0.196). This can be attributed to larger sample size although a wider confidence (99%) interval was considered.
