When you graph an equation, it should be dependent variable against the independent variable. For this problem, the independent variable is the time, so this is along the x-axis. The dependent variable is d, so this is along the y-axis. Since the slope is Δy/Δx, then it is also equivalent to Δd/Δt. Therefore, the answer is B.
Answer: Option A.
Step-by-step explanation:
1. Dilation is defined as a transformation in which the figure is enlarged or reduced.
2. For dilation you have:
- A scale factor, that determines how much the figure will be reduced or enlarged.
- The center of dilation, which is defined a a fixed point in the plane.
3. If the figure is dilated with a scale factor of 4 and the center of dilation at the origin, you must multiply the coordinates of the original figure bu 4. Then:
(x,y)---->(4x,4y)
Answer:
1. x=4+2y/3
2. x=3/4+y/2

Answer:
a)
90% confidence interval for the mean grading time of all composition papers.
(12.47981 , 13.52019)
b)
Appropriate inequality
The interval is ( 12.47981 < μ < 13.52019)
Step-by-step explanation:
<u><em>Explanation</em></u>:-
a)
Given sample size 'n' = 40
Mean of the sample = 13 minutes
standard deviation = 2 min
level of significance = 0.10 or 90%
90% confidence interval for the mean grading time of all composition papers.
( 13 - 0.52019 , 13 + 0.52019)
(12.47981 , 13.52019)
b)
The interval is ( 12.47981 < μ < 13.52019)
Answer:
3 inches per hour
Step-by-step explanation:
divide the number on the y axis (i'm assuming it's inches of snow) by the number on the x axis (i'm assuming its hours)
by doing this you will get 3 inches per hour
