Answer:
c=10 units
Step-by-step explanation:
The Pythagorean Theorem states that a^2+b^2=c^2.
This means that the sides are represented by a^2+b^2. In order to find the hypotenuse in this problem, we substitute a and b for 6 and 8.
6^2+8^2=c^2
we do what it shows us and get:
36+64=c^2
from there, we add the left side altogether then square each side to get rid of the root.
100=c^2
√100=√c^2
and we get c =<em> 10 units.</em>
Answer:
(26.6,29.4)
Step-by-step explanation:
The 98% confidence interval can be computed as
Point estimate± Margin of error
Point estimate=mean number of hours watching TV by college students=28.
Margin of error=1.4.
The 98% confidence interval for mean number of hours watching TV per week for all college students
28± 1.4
(28-1.4,28+1.4)
(26.6,29.4).
Answer:
x=2y+8

Answer:
Step-by-step explanation:
5. You are asked to write an equation of the line in slope-intercept form, so you need to determine the slope of the line and the y-intercept.
You're lucky. One of the points, (0,1), has an x-coordinate of 0, so you know that the y-intercept is 1.
Use the coordinates of the points to determine the slope of the line.
slope = (difference in y-coordinates)/(difference in x-coordinates) = (10-1)/(3-0) = 9/3 = 3
The slope-intercept equation of the line is y = 3x+1

7. When x = 0, function A = 0 and function B = 3, so function B has a greater initial value.
