Answer:

-8655 = x

Step-by-step explanation:

Here is a method I call I move, you move, raise the roof, meaning that whenever our divisor is a decimal, we need to move the decimal point a quantity of times to make it a whole number, then the quantity of times we have moved the decimal point in the divisor, goes for the dividend as well, and the rest of the empty spaces are zeros as placeholders. So, if you had a difficult time dividing like this, do this:

20287320 ÷ -2344

Dividend Divisor

It is much easier to divide now, and of course we all know how to determine if our answers will be negative or positive, so that should be a piece of cake. In the dividend, as mentioned before, in the ones place, there is a zero as a placeholder.

**The quantity of times you move the decimal point in the divisor, is quantity of times you move the decimal point in the dividend.

For each sequence, find the first 4 terms and the 10th term 1) 2n-1

Katena32 [7]

Answer:

1st term: 1, 2nd term: 3, 3rd term: 5, 4th term: 7 & 10th term: 19

Step-by-step explanation:

1st term: 2(1) - 1

2 - 1 = 1

2nd term: 2(2) - 1

4 - 1 = 3

3rd term: 2(3) - 1

6 - 1 = 5

4th term: 2(4) - 1

8 - 1 = 7

10th term: 2(10) -1

20 - 1 = 19

The solution to the system equations

katovenus [111]

Let's solve this system of equations through substitution.

We have these two equations.

-7x-2y=14

6x+6y=18

Now let divide the second equation by 6.

6x+6y=18 ----> x+y=3

Next, let us move y to the right side of the equation.

x+y=3 -------> x=3-y (x equals 3-y)

Because we found out that what x is in terms of y, we can input that in for every instance of x in this equation below.

-7x-2y=14 becomes -7(3-y)-2y=14 (Why? Because x equals 3-y!)

We have a one variable equation now and can solve for y.

-7(3-y)-2y=14

-21+7y-2y=14

5y=35

y=7

Plug in 7 for y in any equation to find x.

x+y=3

x+7=3

x=-4

answer: x=-4, y=7

Which of the following estimates at a 95% confidence level most likely comes from a small sample?

dusya [7]

The correct answer is:

A) 60% ± 18%.

Explanation:

In a confidence interval, the margin of error is given by z*(σ/√n), where σ is the standard deviation and n is the sample size.

First we find the value of z:

We want a 95% confidence level; 95% = 95/100 = 0.95.

To find the z-score, we first subtract this from 1:
1-0.95 = 0.05.

Divide by 2:
0.05/2 = 0.025.

Subtract from 1 again:
1-0.025 = 0.975.

Using a z-table, we find this value in the middle of the table. The z-score that is associated with this value is 1.96.

Back to our formula for margin of error, we have 1.96(σ/√n). The larger n, the sample size, is, the larger its square root is. When we divide by a larger number, our answer is smaller; this gives us a smaller margin of error.

This means that if we had a small sample size, we would divide by a smaller number, making our margin of error larger. The largest margin of error we have in this question is 18%, so this is our correct answer.
