Hey there!
In order to see if it's a function or not, it can't have the same x value twice, or it just has to pass the vertical line test.
This means that you could put a vertical line anywhere and it would not pass between two points.
If we look, we could indeed try the vertical line test, and and there would be no intersection between two points.
Additionally, we also do not have any repeating x values on this quadratic function's parabola.
Hope this helps!

WARRIOR [948]

Answer:

0.3 or 30%

Step-by-step explanation:

The professors will only seek a smaller publisher if they cannot place the statistics book with a major publisher. If the probability of getting a major publisher is 40% and the probability of getting a smaller publisher is 50%, then the probability that the statistics book would wind up being placed with a smaller publisher is given by:

$P=(1-P(major))*P(minor)\\P=(1-0.4)*0.5\\P=0.3$

The probability is 0.3 or 30%.

Ruth found 37 tickets for $7. Please help Ruth by figuring out the ratio. (round to 2 decimal places)

Amanda [17]

Answer:

Ratio of ticket to its price is 1 : 0.189.

Step-by-step explanation:

Here, the cost of 37 tickets = $7

Let us find the unit cost of the ticket.

$\textrm{Unit Price } = \frac{\textrm{Total Price of n units}}{\textrm{n}}$

$\implies U = \frac{7}{37}=0.189$

So, the unit price of each ticket = $0.189

Now, ratio of Each Ticket: Unit Price = 1 : 0.189

Hence, the ratio of ticket to its price is 1 : 0.189.

What's the probability of getting an odd number and a head when rolling a die and then tossing a coin?

nikdorinn [45]

P(getting odd number) = 3/6 = 1/2 ( as there are 3 odds and 3 evens on a die).

P(head) = 1/2

these are multiplied as the 2 events are independent :-
Answer is 1/2 * 1/2 = 1/4

taurus [48]

The term "concurrent validity" refers to the relationship between step count with vo2 data.

<h3>Define the term concurrent validity?</h3>

The degree of agreement between two measurements or assessments made at the same time is displayed by concurrent validity.
It contrasts a brand-new test with one that has already undergone testing and been shown to be reliable.

You wish to evaluate a new survey that measures employee commitment's concurrent validity. In order to accomplish so, you may:

Ask the same group of employees to respond to your new survey as well as an earlier (validated) survey. then contrast the outcomes.
Obtain some staff responses to your new survey. The findings of a popular employee performance indicator, including a performance evaluation, should then be compared to the respondents' responses.

There is a connection between daily step count and fitness level (as collected with vo2 testing)

Thus, the term "concurrent validity" refers to the relationship between step count with vo2 data.
