The graph which is a one-to-one function is:
Graph B
<h2>
Step-by-step explanation:</h2>
Function--
The graph of a function must always pass the vertical line test i.e. any line passing through the domain and parallel to the y-axis must pass through the graph exactly once.
and also for a function to be<em> one-one</em> the graph of the function must pass horizontal line test i.e. any line passing through the co-domain and parallel to the x-axis must intersect the graph at most once.
In the given graphs :
Graph A is not a function, since it does not pass the horizontal line test and hence we won't talk about being a one-one function.
Graph B is a function as well is one-one since it passes horizontal as well as vertical line test.
Graph C is a function but is not one-one as it fails the horizontal line test.
Hence, the correct answer is:
Graph B
Answer:
3025
Step-by-step explanation:
let's look at it in this concept.
For a number to be divisible by 11 and 5. it must be a multiple of the LCM of 11 and 5.
LCM of 11 and 5=55
therefore the number is 55x, where x is a positive integer.
it is a said that the number is a perfect square
therefore the square root of 55x must be an integer.
the smallest value of x to make 55x a perfect square is....
Therefore the number is.... .

Answer:
A one-tailed hypothesis will be used to perform the test.
Step-by-step explanation:
The purpose of the marketing research consultant hired by Coca-Cola is to determine whether the the proportion of customers who prefer Coke to other brands is over 50%.
The marketing research consultant selected a random sample of <em>n</em> = 200 customers. The sample proportion of people who favored Coca-Cola over other brands was 55%.
The marketing research consultant can perform a single proportion hypothesis test to determine whether greater than 50% of customers prefer Coca-Cola to other brands.
Since we need to determine whether the population percentage is greater than a null value, the hypothesis is not two-tailed.
The hypothesis can be defined as:
<em>H₀</em>: The proportion of people who favor Coca-Cola over other brands was 55%, i.e. <em>p</em> = 0.50.
<em>Hₐ</em>: The proportion of people who favor Coca-Cola over other brands was more than 55%, i.e. <em>p</em> > 0.50.
Thus, a one-tailed hypothesis will be used to perform the test.
