Step-by-step explanation:
Answer: cross-sectional study
Step-by-step explanation:
- A cross-sectional study is a kind of research study in which a researcher collects the data from many different persons at a single point in time.
- In this study researcher observes the variables without influencing them.
Here, A research company uses a device to record the viewing habits of about 2500 households (that includes different persons such as adults , children and seniors )
The data collected today(at a single point in time).
If it is used to determine the proportion of households tuned to a particular children's children's program.
The type of observational study is described in the problem statement : "cross-sectional"
Answer:
Step-by-step explanation:
The zeros are where the graph intersects the x-axis
x = 0
x = 2
x = 4
------------------------
Extra Credit
Note x = 2 is a double zero since it touches, but does not cross the x-axis
The equation is
y = -x(x - 2)²(x - 4)
"Integer" I think! As all rational numbers can be written as integer fractions.
The equation representing the given statement is ~
The least number of lawns that he can cut and buy the computer is 10 lawns ~
Total savings should be greater or equal to $ 820 in order to buy the computer,
And his total savinga is equal to ~
Money he saved + money got from cutting lawns.
let's assume the lawns cut by Tyrod be x,
Money earned by cutting lawns is equal to
- total number of lawns cut × $50
total savings is equal to ~
hence,
by solving for " x (number of lawns cut) " we get ~
Hence, the least number of lawns he has to cut is the number that is greater than 9.8, which is
