Which set of ordered pairs does not represent a function?

Mathematics
1 answer:
ser-zykov [4K]2 years ago
7 0

Answer: set 2 : O{(-6, -7), (-3, -3), (-2,-8), (-6,4)}

Step-by-step explanation: In order for a set of ordered pairs to be a function, then each input can correspond to only 1 output. In the context of your question, this means there cannot be two ordered pairs which have the same x value. The second set of ordered pairs does not represent a function because the input x = -6 corresponds to two different outputs, y = -7 and y = 4.

True or false the opposite sides of a kite are never parallel
Rasek [7]
Answer: True

If the opposite sides were parallel, then you would have a parallelogram (which isn't a kite). A parallelogram has opposite sides that are congruent.  

A kite is a figure with adjacent sides that are congruent. A kite does not have opposite sides that are congruent.

Can someone help please ? Answer correctly for brainliest and a thanks ! Don't answer if you don't know it please !
professor190 [17]
The first one would be approximately -0.8. It has a negative slope and the data points are fairly close together. The second one is almost a straight line so it would be very close to 1. I would say 0.97 The closer the data is to a straight line the closer the r value is to 1 or negative 1. Hope this helps.

Scott is on his school's academic team. On average, it takes Scott 4 minutes, with a standard deviation of 0.25 minutes, to solv
uysha [10]

Answer:

15.87% is the chance that Scott takes more than 4.25 minutes to solve a problem at an academic bowl.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 4 minutes

Standard Deviation, σ = 0.25 minutes

We standardize the given data.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(more than 4.25 minutes to solve a problem)

P( x > 4.25) = P( z > \displaystyle\frac{4.25 - 4}{0.25}) = P(z > 1)

= 1 - P(z \leq 1)

Calculation the value from standard normal z table, we have,  

P(x > 4.25) = 1 - 0.8413 = 0.1587 = 15.87\%

Thus,15.87% is the chance that Scott takes more than 4.25 minutes to solve a problem at an academic bowl.
