What is the sum of the first 1,000 consecutive odd numbers?

That is an arithmetic sequence of the form:

a(n)=2n-1

Now the sum of an arithmetic sequence is just the average of the first and last terms times the number of terms...

We know the first term is 1, let's find the last term...

a(1000)=2(1000)-1=1999

So the sum of that sequence is:

1000(1999+1)/2

1,000,000

Race relations: A New York Times/CBS poll surveyed 1,027 adults nationwide about race relations in the United States. Of the sam
Montano1993 [528]

Answer:

D. We are 95% confident that the proportion of all Americans who say that race relations in this country are generally bad is between 58% and 64%.

Step-by-step explanation:

The 95% confidence interval refers that 95% of data is correct with respect of the population

Given that 95% confidence interval is (0.58, 0.64)

So based on this, the option D is correct as it shows the right thing with regard to 95% confidence interval

Therefore all the other options are incorrect as the first option is of probability, the second option is the sample, and the third option is of statement form i.e not standardized.

A 34-ft. ladder resting against the wall of a building forms a right triangle with the wall and ground. The bottom of the ladder
BigorU [14]

The ladder resting against the house forms a triangle similar to the one in the image below

To answer this question you must use Pythagorean theorem

a^{2} +b^{2}=c^{2}

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = x

b = 8

c =  34

^^^Plug these numbers into the theorem

x^{2} +8^{2} =34^{2}

solve for x

x^{2} + 64 = 1156

Subtract 64 to both sides

x^{2} = 1092

Take the square root of both sides

x = √1092

This can be simplified to:

2√273

or

x ≈ 33.045...

The ladder reached roughly 33.05 ft up the wall of the building

Hope this helped!
