2sin x=√3
sinx=√3/2

x=arcsin √3/2=π/3  + 2Kπ U  2π/3+2Kπ

Sol: π/3  + 2Kπ   U    2π/3+2Kπ ;       K∈Z

π/3+2Kπ=60º+360ºk    
2π/3+2Kπ=120º+360ºK

sveticcg [70]

Answer:

No, because the sample was randomly selected.

Step-by-step explanation:

In this example, the main element that we need to focus on is the way in which the sample was determined. We learn that the sample was taken in California with 1000 people. However, this sample was random, and the survey was conducted in both English and Spanish. The fact that this was a random sample means that it is representative of the population. The size of the population does not affect the accuracy of a random sample.

What is the value of 4(-1+2-3+4-5+6-7+......+1000)???
ANTONII [103]

Answer:

<h2>            4(-1+2-3+4-5+6-7+......+1000) = 2000</h2>

Step-by-step explanation:

-1+2 = 1

-3+4 = 1

-5+6 = 1

and so on till -999+1000 = 1

1 ....  1000    - these are 1000 numbers, so

1000:2 = 500   pairs with sum equal 1

4(500•1) = 4•500 = 2000
