Answer:

1. Yes

2. Yes

3. No.

Step-by-step explanation:

1. Only one output y for the same x values

2. Only one output y for the same x values

3. More than one output y for the same x values

A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y

Answer:

The graph is a function because of the vertical line test.

The second one is not a function because it has 2 of the same x coordinate.

The third one is not a function because it has 2 of the same x coordinate.

Chris pays a fee if her balance falls below $10 on the statement data. Prior to the statement date, her balance was -$3.46. Then

alisha [4.7K]

Answer:

The solution of the inequality required for the situation is d ≥ $13.46.

Step-by-step explanation:

i) the minimum deposit is $10.

ii) the balance before the statement is $-3.46

iii) a deposit d is made so that the fee did not have to be made

iv) therefore d + (-3.46) ≥ 10

d - 3.46 ≥ 10

therefore d ≥ 10 + 3.46

therefore d ≥ $13.46

Assume that you assign the following subjective probabilities for your final grade in your econometrics course (the standard GPA

rodikova [14]

Answer:

$E(X) = 4*0.2 +3*0.5+ 2*0.2 +1*0.8+ 0*0.02= 2.78$

So then the best answer for this case would be:

C. 2.78

Step-by-step explanation:

For this case we have the following probabability distribution function given:

Score P(X)

A= 4.0 0.2

B= 3.0 0.5

C= 2.0 0.2

D= 1.0 0.08

F= 0.0 0.02

______________

Total 1.00

The expected value of a random variable X is the n-th moment about zero of a probability density function f(x) if X is continuous, or the weighted average for a discrete probability distribution, if X is discrete.

If we use the definition of expected value given by:

$E(X) = \sum_{i=1}^n X_i P(X_I)$

And if we replace the values that we have we got:

$E(X) = 4*0.2 +3*0.5+ 2*0.2 +1*0.8+ 0*0.02= 2.78$

So then the best answer for this case would be:

C. 2.78
