Let y be your total price for buying juice at the farmers market. And x be the amount of juices you buy. If each juice cost 5 bucks then you multiply 5 by x(amount of juice) to get y(your total)
Answer:
Step-by-step explanation:
Given that confidence level is 95% and sample mean is within 10 minutes of the population mean. i.e. margin of error = 10
Std deviation of population= 211 minutes
Margin of error = Z critical * std error
Std error = sigma/sq rt n = ![\frac{211}{\sqrt{n} }](https://tex.z-dn.net/?f=%5Cfrac%7B211%7D%7B%5Csqrt%7Bn%7D%20%7D)
Hence we have
\frac{211}{\sqrt{n} }![\frac{211}{\sqrt{n} }*1.9641.356\\n>1710](https://tex.z-dn.net/?f=%5Cfrac%7B211%7D%7B%5Csqrt%7Bn%7D%20%7D%2A1.96%3C10%5C%5C%5Csqrt%7Bn%7D%20%3E41.356%5C%5Cn%3E1710)

Question not well presented
Point S is on line segment RT . Given RS = 4x − 10, ST=2x−10, and RT=4x−4, determine the numerical length of RS
Answer:
The numerical length of RS is 22
Step-by-step explanation:
Given that
RS = 4x − 10
ST=2x−10
RT=4x−4
From the question above:
Point S lies on |RT|
So, RT = RS + ST
Substitute values for each in the above equation to solve for x
4x - 4 = 4x - 10 + 2x - 10 --- collect like terms
4x - 4 = 4x + 2x - 10 - 10
4x - 4 = 6x - 20--- collect like terms
6x - 4x = 20 - 4
2x = 16 --- divide through by 2
2x/2 = 16/2
x = 8
Since, RS = 4x − 10
RS = 4*8 - 10
RS = 32 - 10
RS = 22
Hence, the numerical length of RS is calculated as 22
