Answer:
20%
Step-by-step explanation:
To find what percentage is $10 out of $50, we divide 10 by 50:
![\frac{10}{50}=0.2](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%7D%7B50%7D%3D0.2)
If we want to get the result in percentage form, we simply multiply it by 100%:
![0.2\cdot 100\%=20\%](https://tex.z-dn.net/?f=0.2%5Ccdot%20100%5C%25%3D20%5C%25)
So a tip of $10 on a $50 bill is a tip of 20%.
Answer:
Step-by-step explanation:
Select the correct answer from each drop-down menu.
We solve using z score formula
z-score is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
The average time taken to complete a test follows normal probability distribution with a mean of 70 minutes and a standard deviation of 25 minutes.
a) The probability of a randomly selected student completing the test in 45 minutes or less is approximately equal to %.
z = 45 - 70/25
b) The probability of a randomly selected student completing the test in 95 minutes is %.
z = 95 - 70/25

Answer:
the markup percentage is 66.67%
Step-by-step explanation:
The computation of the percent of markup based on cost is shown below:
= (Selling price - paid price) ÷ (paid price)
= ($15 - $9) ÷ ($9)
= 66.67%
By taking the difference of the selling price & paid price and then divided it by paid price we can get the percentage of markup
Hence, the markup percentage is 66.67%
Check the picture below.
to graph a LINEar equation, since it's just a line and for a line all you need is two points and draw away, simply pick two random "x" values to get the "y" values and plot those two points.
for y = -x + 2
if we choose x = 0, then y = -0 + 2 => y = 2, that gives us the point (0 , 2)
if we choose x = 2, then y = -2 + 2 => y = 0, that gives us the point (2 , 0)
graph it and we get the blue line.
for the 2nd equation
![y = \cfrac{2}{3}x-1\hspace{5em}\underline{x=3}~\hfill y=\cfrac{2}{3}(3)-1\implies y=2-1\implies y=1 \\\\\\ ~\hfill \boxed{(3~~,~~1)} \\\\\\ ~\hspace{9.5em}\underline{x=0}~\hfill y=\cfrac{2}{3}(0)-1\implies y=-1 \\\\\\ ~\hfill \boxed{(0~~,~~-1)}](https://tex.z-dn.net/?f=y%20%3D%20%5Ccfrac%7B2%7D%7B3%7Dx-1%5Chspace%7B5em%7D%5Cunderline%7Bx%3D3%7D~%5Chfill%20y%3D%5Ccfrac%7B2%7D%7B3%7D%283%29-1%5Cimplies%20y%3D2-1%5Cimplies%20y%3D1%20%5C%5C%5C%5C%5C%5C%20~%5Chfill%20%5Cboxed%7B%283~~%2C~~1%29%7D%20%5C%5C%5C%5C%5C%5C%20~%5Chspace%7B9.5em%7D%5Cunderline%7Bx%3D0%7D~%5Chfill%20y%3D%5Ccfrac%7B2%7D%7B3%7D%280%29-1%5Cimplies%20y%3D-1%20%5C%5C%5C%5C%5C%5C%20~%5Chfill%20%5Cboxed%7B%280~~%2C~~-1%29%7D)
graph it and we get the red line
notice, those points are in those lines, and to graph a LINE, all you need is two points.
