Answer:

<h2>D.</h2><h2>{(-9,8), (-5,-8), (-7,8), (-6,-8)}</h2>

Step-by-step explanation:

A function is defined as the relation between two sets with an specific characteristic:

  • If each x-value has only one y-value assigned, then the expression it's a function.
  • If each x-value has more than one y-value image, then the expression it's not a function, it's just a relation.

So, in this problem, we have to look for this characteristic. Option A has two points with the same x-value and different y-value assigned, so it's not a function. Option B has two y-values assigned for x=8, so it's not a function either. Option C is not a function because x=13 has to different images y=-3 and y=0.

At last, option D represent a function, because each x-value has only one image: {(-9,8), (-5,-8), (-7,8), (-6,-8)}

It's important to notice that, one y-value can have different x-values assigned, that's a function, but it cannot happen in the opposite way, one x-value with more than one y-value assigned.

Therefore, the right answer is D.

Answer Choices : (A) 1/6 (B)5/36 (C) 1/2 (D) 1/36
Sati [7]

Answer:

Probability = \frac{1}{6}

Step-by-step explanation:

Given

The above table

Required

Determine the probability of a sum that is a multiple of 6

Represent the event that an outcome is a multiple of 6 with M.

List out all possible values of M

M = \{6,6,6,6,6,12\}

Number of M is

n(M) = 6

Total possible outcome is:

n(Total) = 36

The theoretical probability is then calculated as follows:

Probability = \frac{Number\ of\ desired\ outcomes}{Number\ of\ possible\ outcomes}

In this case, it is:

Probability = \frac{n(M)}{n(Total)}

Probability = \frac{6}{36}

Simplify fraction

Probability = \frac{1}{6}

A large population of variable x is characterized by its known mean value of 6.1 units and a standard deviation of 1.0 units and
scoundrel [369]

Answer:

-6.134 to +6.134

Step-by-step explanation:

given that a large population of variable x is characterized by its known mean value of 6.1 units and a standard deviation of 1.0 units and a normal distribution

X is Normal with mean  =6.1 and std dev = 1 unit

We are to determine the range of values containing 70% of the population of x

We know that normal distribution curve is bell shaped symmetrical about the mean.

So to find 70% range we can use 35% on either side of the mean

Using std normal distribution table the value of z for which probability from 0 to z is 0.35 is 1.034

Hence corresponding x value is

x=6.1+1.034*1\\x=6.134

i.e. 70% values lie between

-6.134 to +6.134
