What is a Dependent event

1 answer:

7 0

Step-by-step explanation: If events are dependent, this means that the outcome of the first event will affect the outcome of the second event.

Let's look at an example.

Gianna has 8 blue socks and 4 red socks in her sock drawer. She chooses one sock at random and puts its on. She then chooses another sock without looking. Find the probability of the following event.

P (red, then red)

These would be dependent events because if she puts a sock on and doesn't replace it, there is 1 fewer sock in the drawer which affects the probability.

A system of equations is given below. y=1/2x-3 and -1/2x-3. Which of the following statements best describes the two lines?

pantera1 [17]

"They have different slopes but the same y-intercept, so they have one solution" is the statement which best describes the two lines.

Answer: Option D

<u>Step-by-step explanation:</u>

Given equations:

$y=\left(\frac{1}{2} \times x\right)-3$

$y=\left(-\frac{1}{2} \times x\right)-3$

As we know that the slope intercept form of a line is

y = m x + c

So, from equation 1 and equation 2 we can see that

$m_{1}=\frac{1}{2} \quad \text { and } c_{1}=-3$

$m_{2}=-\frac{1}{2} \text { and } c_{2}=-3$

So, from the above expressions, we can say that both lines have different slopes but have same y – intercept with one common solution when x = 0.

PLEASE HELP!!

Answer:

A. 90°+m∠4

Step-by-step explanation:

Also

∠ A + ∠ C = 180 o = ∠ B + ∠ D

⇒ 2 x+ ( 3 x − 5 ) = 180 0 = ( x + 5 ) + ∠ C

5 x − 5 = 180

Add 5 to both sides

5 x = 185

Divide both sides by 5

x = 185 5 = 37

But it was A. 90°+m∠4

What is the explicit rule for the arithmetic sequence shown in the graph?

Afina-wow [57]

Answer:

Step-by-step explanation:

Looking at the given graph, the slope of the line is expressed as

Slope = (y2 - y1)/(x2 - x1)

y2 = 19.5

y1 = 9.5

x2 = 6

x1 = 1

Slope = (19.5 - 9.5)/(6-1)

Slope = 10/5 = 2

The successive terms is increasing by 2

The formula for the nth term of an arithmetic sequence is expressed as

Tn = a + (n - 1)d

Where

a is the first term of the sequence

n is the number of terms in the sequence.

d is the common difference.

From the information given,

a = 9.5

Tn = an

d = 2

The explicit rule for the arithmetic sequence will be

an = 9.5 + 2(n-1)
