The answer is B) 1/3.
There are 6 faces on a rectangular prism, each of which is a rectangle.
The area of the front and back is given by 25(8) = 200 sq. cm.
The area of the bottom and top is given by 25(4) = 100 sq. cm.
The area of the right and left is given by 4(8) = 32.
There are 2 faces out of 6 with an area that is not a multiple of 100; 2/6 = 1/3.
Answer:
c
Step-by-step explanation:
If the dot product of the vectors is zero then they are perpendicular
(5, - 1) • (- 3, 6)
= (5 × - 3) + (- 1 × 6) = - 15 + (- 6) = - 15 - 6 = - 21 ≠ 0
Since product is not zero vectors are not perpendicular
The margin of error of the random selection is 0.29
The given parameters are:
--- the sample size
--- the standard deviation
--- the mean
--- the confidence level.
The margin of error (E) is calculated as follows:
So, we have:
The z-value for 90% confidence level is 1.645.
Substitute 1.645 for z
Take square roots
Multiply
Approximate
Hence, the margin of error is 0.29

Answer:
Substitution
Step-by-step explanation:
tbh i havent checked so sorry if its wrong
P = √ab
p² = ab
p²/b = a
a = p²/b
