Answer:
![-\frac{1}{2}y-\frac{11}{24}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B2%7Dy-%5Cfrac%7B11%7D%7B24%7D)
Step-by-step explanation:
![\frac{3}{8}\:-\:\frac{1}{2}y-\frac{5}{6}\\\\ =-\frac{1}{2}y+\frac{3}{8}-\frac{5}{6}\\\\ =-\frac{1}{2}y-\frac{11}{24}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B8%7D%5C%3A-%5C%3A%5Cfrac%7B1%7D%7B2%7Dy-%5Cfrac%7B5%7D%7B6%7D%5C%5C%5C%5C%20%20%3D-%5Cfrac%7B1%7D%7B2%7Dy%2B%5Cfrac%7B3%7D%7B8%7D-%5Cfrac%7B5%7D%7B6%7D%5C%5C%5C%5C%20%20%3D-%5Cfrac%7B1%7D%7B2%7Dy-%5Cfrac%7B11%7D%7B24%7D)
a)
This sampling technique is simple random sampling, since the students are selected at random by drawing their names from a piece of paper.
b)
Since there is a condition to select a resident (being the sixth resident of the list), this technique is classified as systematic random sampling.
c)
The 20 students were selected by using a table of random numbers without any criteria. Therefores, this is a simple random sampling technique.
d)
Since, among the 100 selected random people, there was a pre determined subgroup of 5 barangays, this is a stratified random sampling technique.
e)
Since everyone in the sample was selected at random by dwaring lots, this is a simple random sampling technique.
Answer:
12
Step-by-step explanation:
With just the 84.00 of art supplies to break even he would need to sell 10.5 paintings so he will need 11 canvases. So he has spent 95.00 on it all. 95/8=11.875, which rounds up to 12 paintings. 12.00 for canvases plus 84.00 for art supplies is 96.00 spent. Divided by 12 is 0 so that is where he would break even
Answer:
17
Step-by-step explanation:
Answer:
Value of the car is decreasing by 13.9% each year.
Step-by-step explanation:
This equation tells us V(t) is the value of the car after a certain time in years, $21,000 is the initial value of the car. What we need to focus on is on the 0.861 part of this equation. This means that the price of the car is worth 0.861 or 86.1% of what it was worth the year prior, this means that the price of the car is decreasing over time. By how much is it decreasing? Well if we consider 1 to mean 100% (since 100 / 100 =1) then we have 100%-86.1%=13.9%. This means that the value of the car is decreasing 13.9% each year.
