Answer:

(x, y ) → (- y, - x )

Step-by-step explanation:

Consider the coordinates of corresponding vertices of the 2 triangles, that is

A(1, 7 ) → D(- 7, - 1 )

Note the coordinates of D are the negative reversals of A

Thus (x, y ) → (- y, - x )

Answer:

Option A

fraction numerator square root of 2 over denominator 2 end fraction

Step-by-step explanation:

The answer can be obtained using a calculator.

It corresponds to a notable identity

sin (45) = $\sqrt{2}$ / 2

sin (45) = 0.7071

$\sqrt{2}$ / 2 = 0.7071

Suppose a simple random sample of size n = 1000 is obtained from a population whose size is N = 2,000,000 and whose population p

faltersainse [42]

Answer:

$p(x\geq 520) = 0.0293$

Step-by-step explanation:

Given data:

random sample size n = 1000

Population size is N - 2,000,000

P = 0.49

We know

$\sigma_p = \sqrt{\frac{p*(1-p)}{n}}$

$\sigma_ p = \sqrt{\frac{0.49*(1-0.49)}{1000}} = 0.0158$

Probability for having X =520

sample proportion $\hat p = \frac{520}{1000} = 0.52$

$p(x\geq 520) = P(\hat p\geq)$

$= P(Z\geq \frac{0.52 - 0.49}{0.0158})$

$= P(Z\geq 1.89) = 0.0293$

$p(x\geq 520) = 0.0293$

What is the probability of getting a factor of 6 when you have 1 2 3 4 5 6

Marrrta [24]

Hello,

I suppose you mean using all those digits one time.

The sum of the digits is a multiple of 3.
Every number formed with those digits is a multiple of 3.

To be divisible by 2 , the number must end with an even digit (2,4,6)

So probability is 3/6=1/2
