Since .7 is in the tens place you would put 70 0ver 100 as 70/100 which in percent would be = 70%
Answer:
integers, rational numbers
Explanation:
Integers are any whole number (positive or negative). -5 is a whole number, not a fraction or decimal.
Rational numbers can be written in the fraction form a/b where a and b are both integers and b does not equal 0. -5 can be written as -5/1.
Answer:
The 95% confidence interval for population mean is (18.19, 23.81).
Step-by-step explanation:
The confidence interval for population mean using the Student's <em>t</em>-distribution is:
Given:
The critical value of <em>t</em> for <em>α </em>= 0.05 and degrees of freedom, (<em>n</em> - 1) = 19 is:
Compute the 95% confidence interval for population mean as follows:
Thus, the 95% confidence interval for population mean is (18.19, 23.81).
The distance between them = 4.93
Step-by-step explanation:
The distance between two points (x1, y1) amd (x2, y2) is
Now putting the values of (0,2) and (4.5, 0) we get,
= = 4.93 (approx)
