Answer:

the margin of error is 0.05

Step-by-step explanation:

Margin of error = confidence interval ÷ 2

MOE = CI ÷ 2

Confidence interval CI = 0.2 - 0.1 = 0.1

MOE = CI ÷ 2 = 0.1 ÷ 2 = 0.05

the margin of error is 0.05

PLEASE HELP <br> WHAT ARE THE coordinates for the center of the hyperbola??
solong [7]

Answer:

The coordinates of the center of the hyperbola are (1,-3)

Step-by-step explanation:

Equation of a hyperbola:

The equation of a hyperbola with center (x_0,y_0) is given by:

\frac{(x - x_0)^2}{a^2} - \frac{(y - y_0)^2}{b^2} = 1

In this question, we have that:

-x_0 = -1 \rightarrow x_0 = 1

-y_0 = 3 \rightarrow y_0 = -3

The coordinates of the center of the hyperbola are (1,-3)

What fraction represents 0.1875 ft?
aliya0001 [1]

Answer:

There is not much that can be done to figure out how to write 0.1875 as a fraction, except to literally use what the decimal portion of your number, the .1875 , means. Since there are 5 digits in 1875 , the very last digit is the "100000th" decimal place. So we can just say that .1875 is the same as 1875/100000.
