Angelita and Cynthia like to play a video game against each other that is scored by round. The goal is to score as many points a

s possible in each round. Here are summary statistics how many points they each score per round:
Mean Standard deviation
Angelita \mu_A=900μ
A
​
=900mu, start subscript, A, end subscript, equals, 900 \sigma_A=96σ
A
​
=96sigma, start subscript, A, end subscript, equals, 96
Cynthia \mu_C=800μ
C
​
=800mu, start subscript, C, end subscript, equals, 800 \sigma_C=72σ
C
​
=72sigma, start subscript, C, end subscript, equals, 72
Both distributions are approximately normal. Suppose we choose a round at random and calculate the difference between their scores. We can assume that their scores each round are independent.
Find the probability that Angelita's score is higher than Cynthia's.
You may round your answer to two decimal places.
P\left(\text{Angelita higher}\right)\approxP(Angelita higher)≈

Show that 3-underroot2 is irrational​
Greeley [361]

Answer:

Step-by-step explanation:

Hello,

Basically, we need to prove that \sqrt{2} is irrational

Let s assume that \sqrt{2} is rational

it means that we can find p and q (q different from 0) two integers <u>with no common factors other than 1 </u>

so that

   \sqrt{2}=\dfrac{p}{q}

And then we can write that

   2=\dfrac{p^2}{q^2}\\ p^2=2q^2

So p^2 is even so it means that p is even

so p^2 is divisible by 2*2=4

as  p^2=2q^2 it means that q^2 is even, meaning q is even

wait, p and q are then even !? but by definition they have no common factors. This is not possible.

so our assumption that \sqrt{2} is rational is false

So it means that this is irrational

and then 3-\sqrt{2} is irrational too

Hope this helps

You invest $1,000.00 in one account and $4,000.00 in another account. Both accounts have the same interest rate over the same am
STALIN [3.7K]

Answer:

The $4,000.00 account will earn 4 times the amount of interest.

Step-by-step explanation:

$4000 is 4 times $1000, so the interest earned will be 4 times more in the $4000 account as compared to the $1000 account.

1000 x 10% = 100

4000 x 10% = 400

400/100=4
