So,

I'm assuming you want me to make a formula for figuring your points after any given month assuming that you use the site at least once a month and you don't spend your points.

After one month, you will have your base 100 points plus an additional 10 points.

100 + 10 = 110

After two months, you will have gained an additional 10.
110 + 10 = 120

We can put this into a function, where P is your points, and m is the number of months you use the site.

P(x) = 100 + 10m

So after 500 months, you will have:

P(x) = 100 + 10(500) = 5100 points!

This is identical with:
y = 100 + 10m

and

y = 10m + 100

So this can be graphed as a linear equation/function with a y-intercept of 100 and a slope of 10/1.

What is equivalent to -2i(6-7i)
borishaifa [10]

Answer:

-14 - 12i

Step-by-step explanation:

Apply complex arithmetic rule: (ai)(b + ci) = -ac + abi

a = 2, b = 6, c = -7

-( -2(-7) + 2*6i )

-( 14 + 12i)

-14 - 12i

IQ scores are normally distributed with a mean of 100 and a
Alekssandra [29.7K]

Answer:

33.2%

Step-by-step explanation:

Calculate the z-scores.

z = (x − μ) / σ

z₁ = (82 − 100) / 15

z₁ = -1.2

z₂ = (98 − 100) / 15

z₂ = -0.133

Use a chart or calculate to find the probability.

P(-1.2 < Z < -0.133) = P(Z < -0.133) − P(Z < -1.2)

P(-1.2 < Z < -0.133) = 0.4470 − 0.1151

P(-1.2 < Z < -0.133) = 0.3319

Rounded to the nearest tenth, the percentage is 33.2%.

Consider the game where two dice, die A and die B, are rolled. We say that die A wins, and write A &gt; B, if the outcome of rol
In-s [12.5K]

Answer:

a) The probability of a tie is the probability of getting the same outcome in both dice.

First, we roll die A and we get a given outcome. (here the probability is 1 because there is no restriction)

Now we need to roll die B and get the same outcome, so here we have only one possible outcome out of 6, then in this case the probability is 1/6

The joint probability (the product of the individual probabilities) is: P =  1*(1/6) = 1/6

b) We want to find the probability that die A wins.

Here we need to analyze each possible outcome for die A.

Let's define:

pₙ = probability of winning given that the outcome is n.

If the outcome is a 1, die A can only lose or tie, then here:

p₁ = 0

If the outcome is a 2, then die A only wins if die B rolls a 1, (1 outcome out of 6)

Then the probability of winning is:

p₂ = 1/6

If the outcome is a 3, then die A wins if die B rolls a 1 or a 2, here we have two possible outcomes out of 6.

p₃ = 2/6

We already can see the pattern, if the outcome is a 4, we get:

p₄ = 3/6

if the outcome is a 5:

p₅ = 4/6

if the outcome is a 6:

p₆ = 5/6

The total probability is the sum of all the joint probabilities:

For each roll in dice A, the probability is 1/6 (the probability of getting a given outcome)

Then the probability that die A wins is:

P = (1/6)*p₁ + (1/6)*p₂ + ... = (1/6)*(p₁ + p₂ + p₃ + p₄ + p₅ + p₆)

P = (1/6)*(0 + 1/6 + 2/6 + 3/6 + 4/6 + 5/6)

P = (1/6)*(15/6) = 0.4167
