What is the simplified form of the following expression? Assume a greater-than-or-equal-to 0 and c greater-than-or-equal-to 0

14 (RootIndex 4 StartRoot a Superscript 5 Baseline b squared c Superscript 4 Baseline EndRoot) minus 7 a c (RootIndex 4 StartRoot a b squared EndRoot)

7 a c (RootIndex 4 StartRoot a b squared EndRoot)
7 (RootIndex 4 StartRoot a b squared EndRoot)
Negative 7 (RootIndex 4 StartRoot a b squared EndRoot)
Negative 7 a c (RootIndex 4 StartRoot a b squared EndRoot)

use google you idiot omg you're so annoying

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
