It is 0.4 so it should look like this
Answer:
29 seconds
Explanation
anchor dropped in to water at the rate = 2.5 m/s
so for one second = 2.5 m
so for 45 sec= 2.5 x 45 = 112.5 m
but it was already 40 m under water, so it have fallen from= 112.5-40= 72.5 m
so as we know the rate of falling was =2.5 m/s
so for 72.5 meter, it took = 72.5 /2.5= 29 sec
it took for anchor to get down to the water surface after it started dropping.
I believe this is a translation two units up, a reflection across the y-axis, and a reflection across the x-axis. Hope this is accurate & helpful.
Answer:
-b
Step-by-step explanation:
-(a+b) = -a - b
-a -b + a = -b
( the -a + a cancel each other out )
Answer:
The answer to the question is
The percent of the distribution is less than m + d is 84 %
Step-by-step explanation:
To solve the question we list out the variables
Percentage of distribution between m +d and m - d = 68 %
Therefore percentage that are outside the range of m + d and m - d = 32 %
For symmetry to be maintained, of the 32 % that are outside the range of m + d and m - d, 16 % are on either side of the range m + d to m - d
That is 16 % < (m-d) ↔ (m+d)< 16% total range = 100 %
Therefore the proportion of the range lesser than m+d = 100 - 16 or 84 %
