Which relation is a function of x?<br> 1 {(1,2), (7, 6), (3, 2), (1, 0), (5, 6)}. <br> 3. x=3y²–7
avanturin [10]

9514 1404 393

Answer:

  The given graph shows a function of x.

Step-by-step explanation:

Neither 1 nor 3 is a single-valued relation for some values of x. The graph shown passes the vertical line test, so does represent a function.

The graph is a relation that is a function of x.

___

The attached graph is of the equation of 3. A vertical line will intersect the graph in more than one place, so the relation is NOT a function.

recent survey found that 71​% of all adults over 50 wear glasses for driving. In a random sample of 30 adults over​ 50, what is
valentina_108 [34]

Answer:

Mean = 21.3

Standard Deviation = 2.48

Step-by-step explanation:

We are given the following in the question:

p = 71​% = 0.71

Sample size, n = 30

We have to find the mean and the standard deviation of those that wear​ glasses.

\text{Mean} = np\\=30(0.71)\\=21.3

Thus, the mean of those who wear glasses is 21.3

\text{Standard deviation} = \sqrt{npq}\\=\sqrt{np(1-p)}\\=\sqrt{30\times 0.71\times (1-0.71)}\\=2.48

Thus, the standard deviation of those who wear glasses is 2.48

If i= V-1, then which expression is equal to 9i(13i)?<br>F -117<br>H 117<br>G 117i<br>I -117i​
DaniilM [7]

If i= V-1, then -117 expression is equal to 9i(13i)

Step-by-step explanation:

Original problem : 9i(13i)

=> 117i^{2} (Multiply)

=> 117 * -1

=> i^{2} = -1

=> -117

If i= V-1, then -117 expression is equal to 9i(13i)
