List t consists of 30 positive decimals, none of which is an integer, and the sum of the 30 decimals is s. the estimated sum of the 30 decimals, e, is defined as follows. each decimal in t whose tenths digit is even is rounded up to the nearest integer, and each decimal in t whose tenths digit is odd is rounded down to the nearest integer. if 1/3 of the decimals in t have a tenths digit that is even, which of the following is a possible value of e - s ?
i -16
ii 6
iii 10

a i only
b i and ii only
c i and iii only
d ii and iii only
e i, ii, and iii

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
