Which of the following relations represent a function? A. {(-1,-1),(0,0),(2,2),(5,5)}. B. None of these. C. {(0,3),(0,-3),(-3,0)
Cerrena [4.2K]
Answer:
A
Step-by-step explanation:
In a list of ordered pairs, a relation that is a function will not have any repeated x-values.
A -- a function (x-values are {-1, 0, 2, 5} with no repeats)
B -- irrelevant
C -- not a function (x-values are {0, 0, -3, 3} with 0 being repeated)
D -- not a function (x-values are {-2, -1, -2, 2} with -2 being repeated)
Ok so what you fo to solve this is you take .26 and .70 and multiply them. to get 0.183 and then multiply it by 41 which equals 7.462
you then subtract it and get 33.54% still an F sorry I hope you can do do better.
ANSWER: 33.54
here is the problem I used for the equation to solve this.
(.26×.70)×41-41= -X
you do order of operations
P) parrenthises
E) exponents
M) multiplication
D) division
A) Add
S)Subtract
Answer:
This is cluster sampling.
Step-by-step explanation:
American Airlines randomly selects 110 flights during a certain week and surveys all passengers on the flights.
This is a type of cluster sampling.
This type of sampling is done by dividing the population into different groups and a simple random sample of clusters is selected from the population.
Answer:
[0,11]
Step-by-step explanation:
Required
Represent Set of numbers from 0 to 11
<em>In interval notation; the square bracket [ ... ] implies that the number in question is inclusive of the set.</em>
So; Given that
Beginning = 0
End = 11
The interval notation can be represented as [0,11] because both numbers are inclusive of the set.
