Answer:
I'm guessing you are talking about an isosceles RIGHT triangle.
In such a triangle, the length of the hypotenuse equals the length of either leg times the square root of 2.
hypotenuse = 14 * square root of 2 =
14 * 1.4142135623731 = 19.79898987322330
or rounding that equals 19.80 inches

Step-by-step explanation:
<u>Use two pairs of points to work out the equation: </u>
<u>Find the slope:</u>
- m = (5 - 1) / (2 - 1) = 4/1 = 4
<u>Find the y-intercept:</u>
- 1 = 4*1 + b
- b = 1 - 4
- b = - 3
<u>The line is:</u>
Correct choice is D
Answer:
The 99% confidence interval for the proportion of all American adults who blame Barack Obama a great deal or a moderate amount for U.S. economic problems is (0.4894, 0.5706)..
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
For this problem, we have that:

99% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 99% confidence interval for the proportion of all American adults who blame Barack Obama a great deal or a moderate amount for U.S. economic problems is (0.4894, 0.5706)..
Answer:
7630
Step-by-step explanation:
We have that the distance of a comet from Earth is about 7.63*10³ .
This number is given in scientific notation.
We want to write this number in standard form.
Since we are multiplying by a power of 10, we move forward three times.
Therefore in standard form:
