Answer:

Not a discrete probability distribution

Step-by-step explanation:

In order for a distribution to be a discrete probability distribution, the sum of the probabilities must be equal to 1:

Since 0.29 + 0.05 + 0.26 = 0.60, then it is not a discrete probability distribution

Select the correct answer. If f(x) = |x| and g(x) = |x| − 4, which transformation is applied to f(x) to get g(x)? A. a vertical
Ainat [17]

Answer:

<em>D. a vertical transformation of f(x) four units downward</em>

Step-by-step explanation:

f(x) = |x|

In f(x), for every x value you input into x, you get a corresponding y value.

Now look at g(x) = |x| - 4

The part |x| of g(x) gives you the same y-value for each x value as you had in f(x). The part -4, makes each y-value 4 less than it was in f(x). Since every y-value is 4 lower than the corresponding y-value of f(x), the function g(x) is a vertical translation of f(x) four units downward.

What's the answer........................
wariber [46]

Using the general recursive formula, he 25-th term in the arithmetic sequence is 29.7

<h3>How to find the value of a₂₅?</h3>

Here we have an arithmetic sequence with the first term a₁ = 3.3 and the common difference is d = 1.1

Remember that the general arithmetic recursive formula is:

aₙ = a₁ + (n - 1)*d

This formula allows us to find the n-th term of the arithmetic sequence only using the first term and the common difference.

In this case, we just need to replace n by 25 and the values written above.

a₂₅ = 3.3 + (25 - 1)*1.1 = 29.7

We can conclude that the 25th term in the sequence is 29.7

Graph 3x+y=-10 -x+3y=0
nikdorinn [45]

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

We have the equations in the standard form. Convert to the slope-intercept form:

3x+y=-10            <em>subtract 3x from both sides</em>

y=-3x-10

-x+3y=0             <em>add x to both sides</em>

3y=x             <em>divide both sides by 3</em>

y=\dfrac{1}{3}x

-----------------------------------------------------

We need only two points to plot a graph of each function.

y=-3x-10

for x = 0 and for x = -3:

y=-3(0)-10=0-10=-10\to(0,\ -10)\\\\y=-3(-3)-10=9-10=-1\to(-3,\ -1)

y=\dfrac{1}{3}x

for x = 0 and for x = -3:

y=\dfrac{1}{3}(0)=0\to(0,\ 0)\\\\y=\dfrac{1}{3}(-3)=-1\to(-3,\ -1)

Look at the picture.
