Answer:

I'm pretty sure that this is correct.

Step-by-step explanation:

this is the equation of a straight line that is generally written

y = m × x + q

m is the slope of the line and is the proportionality coefficient between y and x.

The larger m is, the more the line is hanging

q (-3) is the intercept with the Y axis and is the value you find if you put x=0 (this is the axis y equation)

similarly if you put Y=0 (that is the equation of X axis you find the intercept with X axis that is X= 3/2

If I am wrong I am SO SO Sorry. But I hope that I Helped! :D

Find a formula for the sum of the first n even integers : 2 + 4 + 6 + ... + 2n.

Sedbober [7]

Let S be the sum,

S = 2 + 4 + 6 + ... + 2 (n - 2) + 2 (n - 1) + 2n

Reverse the order of terms:

S = 2n + 2 (n - 1) + 2 (n - 2) + ... + 6 + 4 + 2

Add up terms in the same positions, so that twice the sum is

2S = (2n + 2) + (2n + 2) + (2n + 2) + ... + (2n + 2)

2S = n (2n + 2)

Divide both sides by 2 to solve for S :

S = n (n + 1)

List all your possibility of outcomes (there are 36 outcomes) if you roll a dice containing numbers 1-6 two times. Determine the

Talja [164]

Check the table attached.

The first coordinates of each pair represent the 1.roll, and the second coordinates the 2nd, roll.

All the possible outcomes are {(1, 1), (1, 2).... (6, 5), (6, 6)}, a total of 36, as can be seen in the table.

Each outcome has a chance of 1 out 36 total possible outcomes of occurring.

So the probability is 1/36=0.02778
