Answer:
Correct choice is C) 
.
Step-by-step explanation:
Given that the dimensions of a box are x, 2x, and 3x.
Now each dimension is decreased by 2.
Then new dimensions of a box are (x-2), (2x-2), and (3x-2).
Now let's calculate the volume of the box which is given by
Volume = (Length) x (Width) x (Height)
Hence correct choice is C) .
Answer:
0.180144 < p < 0.339856
Step-by-step explanation:
According to the Question,
- Given That, Out of 200 people sampled, 52 had kids, Thus the proportion of the mean is 52/200 = 0.26
⇒
standard error of the sample is square root(0.26 * (1-0.26) / 200) = 0.031
⇒alpha(a) = 1 - 99/100 = 0.01
⇒critical probability(p*) = 1 - a/2 = 0.995
⇒assuming a normal distribution, look for the z-score associated with 0.995 cumulative probability
, z-score = 2.576
⇒margin of error(ME) = 2.576 * 0.031 = 0.079856
-
the confidence interval is 0.26 + or - 0.079856
0.180144 < p < 0.339856
Answer:
19mph
Step-by-step explanation:
Divide 57 by 3 and you'll get 19mph - the average speed.
An irrational number is one that cannot be shown as ratio of two integers, an 3.14=314/100 so that means pi is irrational. Another thing to note is that pi is transcendental which means it is not the root of any algebraic equation.
